RCN Approved Modems

RCN is a different ISP (internet service provider). You must meet RCN’s requirements in choosing a modem for their internet service, because they do not offer an actual RCN approved modems list. If you meet RCN’s following qualifications, a modem should work on their network.

  • At least 8 Downstream Channels
  • DOCSIS 3.0 or DOCSIS 3.1 certified
  • Cannot be an eMTA (cable modem and telephone adapter); phone service requires a RCN provided eMTA in addition to an approved modem
  • Customers with fiber-to-the-home service must use a RCN internet device
  • Currently not compatible with the RCN network: Motorola MB8600 DOCSIS 3.1 modem

The modems listed on this page carry the minimum modem requirements for RCN internet service.

Read the Cable Modem Buying Guide to help you choose a modem. Do not forget to purchase your modem accessories.

Internet providers have begun removing some DOCSIS 3.0 modems from their networks. To maximize the years of use from a modem, it is strongly recommended to purchase a DOCSIS 3.1 device (the latest standard).

    • Yes, the NETGEAR C6300BD is compatible with RCN, but it is advised that you do not purchase this modem gateway. This network device contains an Intel Puma chipset, which may give you problems. You can read more about Intel Puma Chipset Defects here. You should pick a different modem.

    • Hi David,

      As stated at the top of the page (bullet list), RCN requires you to use their eMTA (telephone adapter). You can still use your own modem with RCN’s eMTA. Thanks for the question.

      Reply
    • Thanks Felipe for the question.

      Yes, the ARRIS SBG10 will work with RCN’s internet service. It is both a modem and WiFi router. However, you should avoid purchasing the ARRIS SBG10 as it contains an Intel Puma chipset. You can read more about the problems with this chipset on the Intel Puma 6 Modem List Chipset Defects page.

      You should really pick a different device for a hassle free experience. The NETGEAR C7000 is highly recommended.

      • I thought this only worked with Xfinity? I’ve had this router with them for about a year and am switching to RCN, you’re sure this will work with RCN?

        Reply
        • Mike, if you need phone service from RCN, you will need to use a RCN eMTA. If you need the ARRIS SVG2482AC for modem and router use only, you might be able to use it for RCN (the device has 24 downstream channels). RCN states that the only device that does not currently work with their network is the Motorola MB8600.

          To make sure, you should contact RCN and give them your local address. Let us know what they say, Mike.

  1. Does RCN support netgear CM1150V-100NAS.
    It has phone support, so I assume you would also need an eMTA adapter.
    Does that mean you have to pay for VOIP?

    Reply
    • Yes, RCN should support the NETGEAR CM1150V-100NAS since it has at least 8 downstream channels. But since you will need to pay for a separate RCN eMTA device for phone service (verify the cost of the eMTA with RCN for your area), the CM1150V is an expensive device just to use as a modem with 4 ethernet ports. Unless you plan on using the device with another ISP in the future, you would be better off choosing a cheaper modem to use for RCN service.

      Yes, you will have to use RCN’s eMTA device for phone service. There will be a cost for “renting” the eMTA plus the cost for the phone service itself (based on what package you order – phone, TV, internet).

      The RCN eMTA also contains a modem, but you will be stuck with whatever performance they give you instead of choosing your own device.

    • Unfortunately, no, Chris. The NETGEAR C7800 Nighthawk X4S DOCSIS 3.1 Ultra-High Speed WiFi Cable Modem Router Combo is one of only two modems that RCN has specifically stated is NOT compatible with their network (please see the forth bullet point at the top of the page).

      RCN has been trying for months to get the C7800 certified. Sorry, Chris, you will have to choose another device.

    • Yes, James, the NETGEAR CM700 is compatible, but you are mostly likely encountering the Intel Puma chipset defect. You can read about the issues in the link provided.

      In short, you should avoid the CM700. You may want to purchase a different modem.

      • AC1200 just refers to the speed of the WiFi, which NETGEAR has several devices that operate at Internet connection combined speeds of 1200 Mbps. You may be referring to the NETGEAR C6220, which is a modem and router combo unit. And yes, Daniel, it is approved for use on RCN’s network.

        Thanks for asking. Did that answer your question?

        Reply
        • A caveat to that answer… I have one and on moving service from one address 2 block away in Chicago the modem stopped working, despite both RCN service. Apparently the Netgear model I purchased on Amazon, a brand new in the box, was originally a Comcast ordered version. It locked out at the new address and even after factory reset continuously went to “Ready to start your xfinity service” screen on every website after modem / WiFi router initialization. $120 down drain as RCN said that type of lockout of other providers is common with xfinity and other major provider s

          Reply
    • Yes, they are both approved. The NETGEAR CM1000-100NAS means it is a regular NETGEAR retail box. The CM1000-1AZNAS means it is an Amazon packaged box (most likely frustration-free or easy open). The devices in the boxes are the same.

      Thanks for the question, Pedro.

    • Hello SG,

      No, it is not. The Actiontec GT784WNV is a DSL device. RCN requires a cable modem device – a DOCSIS 3.0 or DOCSIS 3.1 modem to be precise.

      Yes, the ARRIS SURFboard SB8200 is compatible with the RCN network. The SB8200 is on the RCN approved modem list and as you said, it does NOT contain the Intel Puma chipset.

      Thanks for the question.

        Thank you for all your great work on this website.

  5. Hello, I am deciding between this two, which one would you recommend for RCN compatibility? Netgear N900 Dual Band Gigabit WIFI Router (CG4500BD) or NETGEAR – N450 WiFi Cable Modem Router (CG3000D v2)?
    Thank you!

    Reply
      • Hello, Thank you for this wonderful resource. I notice that you highly recommend the NETGEAR C7000. However, the description on the Amazon link says that it is

        “Built for fast speed: best for cable provider plans up to 400 mbps speed.Modem technology: Engineered with 24×8 channel bonding and DOCSIS 3.0.”

        I do have the 256 plan (Washington DC) with RCN but this Modem doesn’t seem to give me room to grow. I’d prefer to buy Docsis 3.1 with at least a gig bandwidth modem/wifi combo. Do you have a recommended device?

        Reply
          • Hello Modem Gurus,

            Thank you for your prompt reply. This is very helpful and actually my service level is up to 330Mpbs. These wifi modems are pricey but I have the feeling that if I spend $200 on the Netgear C7000 I’ll end up needing a replacement sooner than later. Although, I’m not sure that with my current modem (its quite old) I’m actually experiencing the full benefits of the 330Mpbs plan. I think I’ll try one of the Docsis 3.1 units you recommend to see if I get full extent of 330Mpbs and still have space to grow when necessary. Thank You!

            Reply
            • Your welcome, LLEE. Yes, DOCSIS 3.1 modems are more expensive than DOCSIS 3.0 devices. Adding WiFi on top of that adds an additional cost. But as you say, if you feel you will be purchasing another device so soon after getting the NETGEAR C7000, it is probably best to future-proof yourself. The choice is yours, obviously. Any DOCSIS 3.1 device will more than allow you to reach the full benefit of your 330 Mbps speed (with plenty of room to grow).

              Reply
    • Pedro, thanks for the question and for pointing out a missing modem on this page. The NETGEAR CM1200 has been added to the RCN approved modems list. Currently, only the Motorola MB8600 and the NETGEAR C7800 are not certified by RCN as DOCSIS 3.1 modems.

      Reply
  6. Sorry, I understand now, the “WiFi” designation indicates that the modem is a modem/router combo with built-in wifi functionality. Sorry for the confusion and unnecessary comment. Please delete both of my comments. But you may still want to consider the 12/27/19 comment from “Michael in New York” relative to RCN’s support of the ARRIS SB8200. Thank you.

    Reply
    • ATC, glad you figured out the “WiFi” designation. Until RCN actually states the ARRIS SB8200 is not compatible with their network, it will continue to be listed as approved. RCN has stated that Motorola MB8600 and the NETGEAR C7800 are not compatible with their network (but only these two DOCSIS 3.1 modems). For people that read the comments, you may want to avoid the SB8200 or all DOCSIS 3.1 modems until RCN gets a handle on these more advanced modems.

      “Michael in New York” may be experiencing a local problem with the SB8200. Other cities may not experience issues.

      Thanks for the input, ATC.

      • Hi Guru,

        The man who will be doing the installation told me I need a docsis 3.1 modem/router combo.
        You say rcn can’t handle docsis 3.1? Does that mean that Arris SBG8300 is a no go? All the modems in the list are 3.0 or they don’t have wifi.

        Reply
        • First of all, avoid the ARRIS SBG8300 as it contains an Intel Puma chipset. If you need a DOCSIS 3.1 modem, it is best to combine that with a separate router, since as you mentioned, all of the modems on the list don’t have a built-in router.

          RCN should be able to handle DOCSIS 3.1 since they only exclude two DOCSIS 3.1 models from being used on their network: Motorola MB8600 and the NETGEAR C7800. All other DOCSIS 3.1 devices should work with RCN since they have only excluded the two model numbers.

          Hope this helps runpazu.

  7. Can you recommend a cable modem to be used with RCN 20 Mbps. The RCN rep told me to not get one that is rated for higher speeds because i would have to pay for service at the next level.

    Edit – I meant to say 250 Mbps not 20 Mbps speed

    Reply
    • Hello KennyD,

      While it is more than you currently need, the NETGEAR CM500 is the best bet here. The modem should reach anywhere between 300-375 Mbps (max theoretical download speed of 680 Mbps). It is only $60 at Amazon.

      FYI, just because you have a faster modem than your speed plan, you don’t “have to pay for service at the next level.” For example, you could purchase an even faster modem now (DOCSIS 3.1 modem), and be set for the future without having to upgrade your modem later. You can stick with the 250 Mbps plan now, and in 3 years upgrade to the Gig Internet plan if you like. The RCN rep is wrong to say “to not get one that is rated for higher speeds because i would have to pay for service at the next level.” Thanks for the question, KennyD.

  8. RCN support today told me that to get VOIP they will provide an emta modem, but the cable modem router that I provide needs to support VOIP. From the list above, none of them seem to support VOIP. What should I do? What should I buy to get VOIP?

    Reply
    • Jaim, no VoIP devices are listed because that is the purpose of the eMTA. If RCN is telling you to use a VoIP device, the NETGEAR CM500V is a top choice.

      But you should verify with RCN about your current modem router device. Reps are known for giving different advice to the same person. Contact RCN just to verify you need to actually purchase another device.

      • Modem Gurus,
        Excellent help thank you. Especially about Puma chipset.
        My problem stemmed from the first two RCN tech support people telling me that to get a landline I needed a cable modem router combo that supported VOIP.
        Subsequently I have talked to three RCN tech support people that tell me the emta modem they provide, free for all their landline customers, works independently of the cable modem router combo. It is not necessary to have a cable modem router that supports VOIP. I can therefore make a choice from your list above, and obviously staying away from Puma devices, as I don’t have one currently. Thanks again

        Reply
        • Thanks for responding back, Jaim. It didn’t make sense that RCN was telling you to use two VoIP devices together. Thank you for sharing your experience with the RCN techs.

          Glad you got the information you were looking for in regards to what device you actually need.

          Reply
    • Unfortunately, since RCN has not yet approved the NETGEAR C7800, you don’t have the option of a modem router combo for DOCSIS 3.1. You could purchase an approved DOCSIS 3.1 modem and a separate router (the TP-Link Archer A7 is a cheap and popular option) to achieve what you need, Chris. Hope this helps you.

    • Hello Cheng,

      The NETGEAR CAX80 is a new device that has just released into the market a couple of months ago. While RCN does not outright claim that the CAX80 would not work with their network, like they do with the Motorola MB8600 and the NETGEAR C7800, it is best to contact your local RCN representatives and get a definitive answer for your residential address. RCN may not have had time to evaluate the NETGEAR CAX80 since it has just released.

      Stay safe, Cheng.

  10. So glad I came across this list! Purchased the C7000 and it’s working great, it might even be safe to say it’s faster than the one we were renting. When I called to have it installed the guy told me I should’ve bout a 3.1 but didn’t offer to back up any particular brand. I’m happy with my purchase. Thanks for providing such an extensive list.

    • Hello Kris,

      Sounds like you got a dud modem. The NETGEAR CM600 is one of the most popular modems and should definitely work with RCN. Return the modem and try another CM600 if you would like. Don’t use a pre-owned modem (if that is what you have) as that introduces different problems like the modem still registered in someone else’s ISP account or defective electronics.

      Good luck, Kris.

        Thanks.

        Reply
  14. I think some of the comments have helped clarify, but just to confirm: at the top you mention the Motorola MB8600 as the only one not compatible. But then in the actual list, most of the modems have an X for WiFi. Does this mean, for example, that the Netgear CM600 will work, it’s just not officially approved by RCN?

    Reply
    • The NETGEAR CM600 is compatible with RCN. The X for WiFi means the device does not have WiFi capabilities; you will need a stand-alone router if you require WiFi. In other words, if a device has an X for WiFi, it means the modem is not a combo modem & router device. Thanks for the question.

      Reply
  15. You note that the C7800 is not supported by RCN in the comments section and refer to the top of the page that lists known non-compatible modems. The C7800 is no longer at the top of the page (only he Motorola is listed) does that mean that the C7800 is supported now?

        • The NETGEAR C7800 just got approved in May 2020. Not all of RCN local regions may have been updated yet. You should wait, Jose; RCN should allow this device (or RCN should put it back on the blacklist of uncertified modems).

          Reply
  16. So, does anyone know why RCN doesn’t support the Motorola MB8600? Seems like they’ve had the same disclaimer on their website for years but haven’t actually made any attempts to certify it.

    Reply
    • No idea why the Motorola MB8600 continues to give RCN problems. It has been listed as a problem for several years as you pointed out, Adam. The good news is the NETGEAR C7800 was listed as problematic for months and was finally approved in May 2020. Hopefully that means the Motorola MB8600 will be approved soon.

      When asked about RCN supporting the newer MB8611, RCN stated they had no information to give on the modem. So it appears that, for whatever reason, the Motorola MB86XX series has issues with the RCN network.

  17. Why does RCN not allow use of BYO EMTA for their phone service? . I just picked up an “exact” same model as RCN Arris TM822G but RCN will not accept it .

    Reply
    • Hello Ed B,

      RCN has not given a reason as to why you must use their own eMTA. It could possibly be a way to collect a rental fee now or in the future. Companies are always trying to find ways to get more money.

      You may want to contact RCN directly to see if they will give you an actual reason or say it is just a company policy reasoning (they will likely ask you for your address and account information). The likely answer is so that RCN can properly setup the phone service with their network for your address.

      Reply
  18. Hi, thanks for this site! Since RCN doesn’t provide this information on their own site, it is extremely helpful.

    Question: Can you verify that 8 channel modems are still compatible?
    Suggestion: Would love if the number of ethernet ports was included.

    Thank you!

    Reply
    • Hi Diane,

      Yes, 8 downstream channel modems are still compatible with RCN service. Unfortunately, adding any more columns to the tables makes it too congested, especially since 50% of viewers of this site are on mobile devices with small screens. If you need multiple ethernet ports, look for devices that include WiFi, which is included in the tables.

  19. Hi! Is the NETGEAR C6250 Modem Router Combo compatible with RCN? I’m in Boston and I’m planning on buying the 100Mbps Internet Plan. Also, thank you for this entire thread! It’s been so so SO helpful! <3

  20. Hi! I’m wondering what modem AND router you would recommend for the most reliable wifi (an NYC apartment building). I know I should go for a 32-channel, DOCSIS 3.1 model.

  21. Hi! What do you recommend for a Chicago apartment that is very long (instead of wide/open) and has concrete walls? I know I need a DOCSIS 3.1 modem/router for the 500 Mbps internet package. Is there a benefit to getting a separate modem + router vs. an all-in-one? Thank you!

    Reply
    • Anna,

      Since you have apartment neighbors, you will want to look at the best WiFi tech available on the market today (WiFi 6). The NETGEAR CAX80 is both a DOCSIS 3.1 modem and a WiFi 6 router. While pricey, it will help to avoid conflicts with your neighbors’ devices.

      You can read about the benefits and drawbacks on combo units and separate devices in the Cable Modem Buying Guide (look under the subheading Pros and Cons of Combo Modem and Router Devices). Hope this helps you, Anna.

    • Yes, the NETGEAR CM2000 is compatible with RCN. The device has been added to the RCN approved modem list. Thanks for the question, Jack.

    • It should be compatible with RCN; only the Motorola MB8600 is not approved for RCN’s network. However, you should really stay away from the NETGEAR CBK752. This device contains the NETGEAR CBR750 modem router which incorporates a bad Intel Puma chipset. You will likely encounter connection issues. Ace, the reality is you should avoid this device.

  22. I have a Arris SB6141 and am seeking RCN approved firmware, I believe the file name is R155_15-1-MOTOSB6141

    How do I receive firmware from RCN for the above Cable Modem?

    Reply
    • Only RCN can push the firmware to your modem (this is done automatically). If they haven’t pushed a certain firmware version yet, it is because they have not fully tested for stability and compatibility with their network. Unfortunately, Fran, you are stuck with what you have until an update by RCN is completed.

    • Yes, the TP-Link Archer A7 is compatible with RCN. It is just a router. Any router will work with internet service. However, only certain modems are approved by internet service providers.

  23. Hi thank you for your list of RCN approved modems. It’s been super helpful. I have a TP-link Archer C50 so basically I really just need the cable modem. I am thinking of signing onto RCN’s 250 or 330 Mbps plan. So seems the following ones would work: Arris SB6183, TP-Link TC-7620, Netgear CM500, ASUS CM16, Motorola MB7420. Hopefully I am correct on this list. So my question: do you have a recommendation of one over another? I am looking for something that works obviously but also that lasts. Thanks in advance for your help.

  24. I was going to go with the NETGEAR CM1200 (w RCN). need up to 1Gig. which router is recommended or is there a different one that would pair up better? was thinking NETGEAR R7000 AC1900 or the R6700 AC1750. Thinking Netgear + Netgear makes sense? or would the TP Link Archer A7 which has been recommended be just as well?

    Reply
    • If you go with all NETGEAR equipment, you can use the Nighthawk app if you have a smartphone. It will probably make the setup process a bit easier. The NETGEAR R6700 is a nice value (currently $82.30 from Amazon). The R7000 is almost twice the price, but you won’t get twice the performance, so that is not a good option. But if you need the best value, you can’t go wrong with the TP-Link Archer A7. There is a reason why it is a top-seller (excellent performance for the price – look at those Amazon reviews). Yes, some review are fake, but even if half are real, there are a lot of positive reviews. Your choice really should be between the Archer A7 or the R6700.

  25. Hello! Great site! Very helpful and informative. I actually have the same question as the previous person who commented on which Modem/Router Combo to buy. I’m currently testing out the Netgear CM500 that was recommended. I’m also trying to decide between inexpensive routers under $150 that could complement this Modem well. I was also thinking of a Nighthawk router because it made sense combining two Netgear products. I was thinking of either the R6400 or R6700 or the TP-Link Archer A7 you mentioned or maybe another TP-Link product. I’m not that familiar with this brand so not sure how good it is but seems to be on everyone’s top list. Although there have been complaints of cheap manufacturing, parts and poor quality control, I think they’re made in Vietnam. So with TP-Link it might be a classic case of if you don’t get a lemon you’re good.

    In regards to the Nighthawk R AC series the main complaint seems to be network drops and it seems to be an issue even with the R7000 due to poor revisions and firmware updates as well as cheaper chipsets being used in newer versions. Here’s a post from someone who discourages the R6700 on Amazon below. Sometimes you really have do to dig into those reviews to find truth. Also complaints of Netgear products crapping out well before time. I’m actually upgrading from two 6yr old Netgear products so I’m wondering if there quality is still good. Before that I had the old Linksys which were also pretty solid. Not sure if when it comes to routers these days it’s just a case of they’re all crappy and you might as well just go with the cheapest that will work for you but it’s been challenging finding one that seems reliable which is what I mostly care about.

    Amazon Review of R6700v2 which is I guess still being sold as the original:

    As others have stated, the Amazon listing is for the R6700 (AC1750) router. The router has now been updated by Netgear as the R6700v2. It uses completely different hardware, likely as a cost-saving measure.
    – The original R6700 used the exact same internal components as the R7000 (AC1900) model. i.e. a Broadcom dual-core chipset at 1Ghz. It only lacked a special slightly faster WiFi mode at 2.4Ghz and the additional rear USB 2.0 port from the R7000.
    – The R6700v2 uses a MediaTek chipset and is now advertised on the box as a ‘dual-core’ processor.

    Note that most positive reviews / speed tests for this model are for the R6700 version, *not* the v2. Every indication I’ve seen is that the R6700v2 is a step down from the original model in terms of speed, reliability, and features (for example, not supporting popular alternative firmware such as DD-WRT).

    Here’s what you should order instead:
    – The R6400 if you want to stay at the $99 price point (https://www.amazon.com/NETGEAR-AC1750-Gigabit-Router-compatible/dp/B00Z0V2NQ8) or – The older R7000 (AC1900) which is $50 more but identical hardware to the original R6700. Most normal households probably don’t need the R7000, and would be perfectly fine with the R6400.

    • Thanks for all the info, Mike. Unfortunately, router reviews are not reliable. Due to differences in building materials, number of devices, neighbors’ devices that can cause interference, a router may perform well in one home, but terrible in another. Wireless routers are hard to gauge performance from due to different situations for every home.

      You should try the TP-Link Archer A7. It is inexpensive and of course, if you get a lemon, return it (nobody is 100% perfect in manufacturing – too many variables to control, like shipping and handling). If a router does not perform like it should, return it and try another product.

      Reply
        • No, Andrea, those devices are both routers. You only use one of the two. The ARRIS SB6183 is a really solid modem (one of the few good modems that ARRIS makes).

  26. I have a Netgear Nighthawk R6700 (AC1750) router, and I’m having real problems with internet performance. If I take the ethernet cable directly from the (Netgear) cable modem and plug it into my laptop I can get speed tests > 600 Mbps. If I plug the cable into my router, and then connect my laptop to the router with an ethernet cable, the speed is never above 250Mbs. I bought a replacement R6700 thinking it was a hardware issue, but I had the same problem. I spent quite a bit of time with Netgear phone support (free for the first 90 days). They made a few suggestions, but they gave up too and offered to send me a replacement. Since the last two had the same problem, I’m not optimistic that a 3rd try with the same model will give me better results.

    • Don’t bother with a third model. You may have interference from the devices in your home or building materials in the walls that are limiting your performance. Here are a couple of suggestions for you, Rich. You may want to try a mesh network to get better coverage in your home. A better option is to go with WiFi 6, the latest standard, which can improve speed and better handle congestion. TP-Link’s WiFi 6 article explains the advantages of of the new standard.

      The recommended WiFi 6 router, the ASUS ROG Rapture GT-AX11000, is out-of-stock by Amazon (only third-party overpriced sellers have stock). You can view Amazon’s stock of WiFi 6 routers on this page if you decide to go that route. There are a couple of TP-Link WiFi 6 routers currently on sale.

      Because everyone’s home is different (different variables to account for), troubleshooting wireless routers is difficult.

      **Update: Just re-read your comment, Rich, and you are not using the router in wireless mode; you are directly connecting the router and laptop with an ethernet cable. That seems like a bad ethernet cable. Have you tried a new ethernet cable? Have you tried running the laptop in WiFi mode? What speeds do you get doing that? Try another ethernet port on the back of the NETGEAR R6700 (maybe the LAN port you are using is bad).

  27. Hi, first of all thanks so much for this helpful site. The info is very helpful. I was wondering about your opinion of Netgear modems vs other companies. I searched through the relevant modems on amazon and (while I know I need to take most reviews with a grain of salt) found lots of comments about Netgear modems only working for a year. Do you have any insight into that?
    Thanks again!

    Reply
    • It is difficult to judge reviews due to many being fake or spam reviews. Some could even be left from competitors to try to make a competing product look bad. Overall, all products could develop problems from any manufacturer. Every company will get bad (and good) reviews. If NETGEAR modems stop working after one-year, that is concerning because their warranty is for only one-year. Patrick, if you are concerned with these reviews (there is no way of telling how many devices are returned to NETGEAR), you have a couple of options.

      One, you can choose another brand. But again, every manufacturer can have bad reviews. Some people have unrealistic expectations. A dog may slobber all over the modem or a kid may throw it against the wall and the customer still expects it to work. Reviews often leave these details out. A second option, is to purchase a protection plan. For Amazon, this is listed in your shopping cart or under the ships from and sold by info. Often these protection plans are priced according to the purchase price of the modem. Hopefully, this helps you make a purchase for whatever brand you choose, Patrick.

  28. Good morning, would you recommend getting 1Gbps internet and also buying the NetgearC7800 Nighthawk Cable Modem WiFi Router Combo that should allow up to 2Gbps or getting the 500Mbps internet plan and buying the Arris SURFboard SBG7600AC2 which should allow up to 600Mbps. We currently have a medium sized house with 4 tenets all running computers/laptops and the usual phones/tech devices. At least 3 users use computers for work/school and 2 of us also use computers for streaming/content creation. Appreciate all the help!

  29. I’m considering a switch from Comcast to RCN and pretty sure my trusty zoom will need to be replaced. It’s only an 8 channel, and about 6 yrs old — but I’m getting excellent connectivity when used with an Apple AirPort Extreme. I was wondering if it’s possible to get a modem + router combo but disable the router portion … it would be a good back up if my current router dies— but I’d rather keep using it for now. Does that make sense, or shoukd I simply get a modem-only and then deal with router replacement when necessary? Also, if I rented a modem from RCN ( any idea which models they lease?) could I still use my own router? I’m thinking of getting either a 300 Mbps or 600 speed plan. Thanks! Great, useful site.

    Reply
    • Yes, it is time for an upgrade for your modem, Art. Yes, you can use a modem and router combo unit with your Apple AirPort Extreme. You would need to enable bridge mode (NETGEAR explains bridge mode here). You may find it more convenient (and cheaper) to simply purchase a cable modem without a router since often times a combo unit’s WiFi performance is hampered on those types of devices. Purchasing a separate router often leads to better WiFi performance and if your modem becomes defective, you don’t have to scrap an entire combo unit; you would still have your router to keep. Your Apple AirPort Extreme should last you years; no need to buy something you don’t actually need right now.

      For the RCN modem models they have, they only list this page with no modem models named but a few pictures. It really depends on what your local RCN office has in their inventory. Yes, you can still use your own router when renting a modem. Renting is expensive (minimum charge is $10 a month – it is actually cheaper to just buy your own device). Hope that helps you with a decision, Art.

      Reply
      • Really appreciate this advice — especially since you’ve confirmed my thoughts about the potential downsides of renting and combo packages. I love the old AirPort Extreme, and the ease of managing the network on the rare occasions when something needs to be tweaked, so it’s good to know there’s still some life in it. I’ve been offered a used modem that would probably be fine once reset, but I think it’s best to buy new and get a warranty (despite horror stories about companies failing to honor them) and a return window if it doesn’t work as expected. RCN doesn’t seem too settled on 3.1 yet, so at this point I think an inexpensive DOCSIS 3.0 is my best bet — if at some point I decide to boost my speed, I can always shop again! The savings on service would pay for new equipment in a couple of months! This modem/router question has been holding up my decision to switch-so thanks very much!

        Reply
        • Thanks for checking out this site, Art. Another thing to consider about used modems is they may not have been deactivated from the previous user’s account and you don’t know what condition it will be in. Maybe somebody used their modem as a kickball. So, buying new is the best option (especially with electronics). Stay safe, Art.

      • Thanks. Good Advice. I currently have the DG2470 with MoCA 2.0 which was supplied by RCN and they are now charging 14.99/Month rental. It probably has the defective chip set also. There have been times where it just stops and I have to reboot the entire system. I have the 250MBS download speed, but I’m more concerned with the WiFi transmission range. I definitely need MoCA since I have a second TV upstairs and a 6 channel TIVO box. I’m guessing the MoCA is in the TIVO and not required in the WiFi Cable Modem/Router. What do you think is the best replacement. I will most likely never go above the 250MBS, but want good WiFi? I really appreciate your site. You are providing a great service.

      The Motorola MG8702 will be an outstanding device for you, John. The only downside is the router is only WiFi 5, while the latest standard is WiFi 6 if you are “future-proofing”. Thanks for the question and the MG8702 has been added to the list above.

  32. Modem Gurus,
    Thank you, you have been very helpful. I have decided on the Netgear C7000 which actually has slightly better WiFi than my current unit. I currently have no WiFi issues, so this should be great. I will check with RCN on the MoCA situation first before purchasing. The price at my local Walmart store is $159.99 which seems very good and will be paid off in about 11 months.
    Thanks again.

  33. Hey modem gurus. Because of the recommendation here to try and save money I bought a used CM500 and went through the steps with RCN to register the mac address to their network. Once it gets connected, the upload portion of a speed test kills its connection to the cable company, and it has to reconnect. I’ve powercycled multiple times, disconnected / reconnected router and modem, done a factory reset, and the connection is still intermittent. I’ve been on with support and all they can recommend to do is powercycle, and it doesn’t change anything. Firmware is v1.01.5

    Right now it’s showing 8 locked channels, and the power meters on http://il.speedtest.rcn.net are in the green.

    Is this a bad modem? Or is there a step I need to take?

    Reply
    • Aaron, you should definitely return that modem. Used electronics are never a good idea. You do not know what abuse the device went through with the previous owners. If you are having this many problems with the NETGEAR CM500, you should return it and buy a new modem. A modem, when connected properly, should not cause this many issues for you, Aaron; it should just work.

  34. Question –
    I am looking for a combo wifi/modem and saw this one: ARRIS SURFboard SBG8300 DOCSIS 3.1 Gigabit Cable Modem & AC2350 Dual Band Wi-Fi Router. Is this compatible with RCN? Yes, I am a gamer and want the best for not only my computer gaming but also my other gaming systems.

    Reply
    • The ARRIS SBG8300 is compatible with RCN. However, you should avoid it, Ingrid, since it contains the Intel Puma chipset, which is bad for gaming. The best modem/router combo is the NETGEAR CAX80, which has WiFi 6. However, it is not sold by Amazon and third-party sellers have it listed at over-inflated prices. If you need something right now, the NETGEAR C7800 would be a solid option and it has no Intel Puma chipset.

  37. Hi Modem Guru(s),
    You are a wizard—and patient!
    Four interconnected Qs for you.
    1) I switched in June to RCN for internet. Got my own modem, a Netgear C7000. Solid, but pricey. I could return it… but tell me, is the Arris 2470a (which I may rent for $15/mo from RCN) just as good?
    2) A related Q re: VOIP from RCN. RCN throws in their eMTA (voice device) *if* you rent their internet modem. But they charge $8/mo for the eMTA if you provide your own internet modem. I guess I lean toward the RCN package: Arris-rental-with-freebie-eMTA. Is this a reasonable approach? Or is the Arris so inferior to the Netgear that I should not switch?
    Oh, and 3) do these internet devices always have 4 ethernet ports? We need at least 3 given our set-up.
    4) One last crazy Q (outside the modem realm per se, and driven by my being a 20th-century geezer):
    Is there any way to avoid the whole VOIP approach, and retain POTS (plain old telephone) voice service with RCN or anybody else? I’d feel safer with POTS in case of complete power failure.
    Many thanks.
    – Jeff

    • Hello Jeff,

      1. No, avoid the ARRIS DG2470 (DG2470A); it contains a bad Intel Puma 6 modem chipset defect. You may encounter connection issues. You are better off with the really solid NETGEAR C7000.

      2. Do not switch. Renting is never a good idea, because you are literally throwing money away. You will never “pay-off” the rental; you just keep paying for it over and over again. Plus with rentals, you may be stuck with a defective chipset modem. Jeff, you are better off purchasing your own devices, so you stay in control of what is used in your home.

      3. Yes, most modem/router combo units include 4 Ethernet ports. A stand-alone modem will usually only include one Ethernet port; on a rare occasion, two ports may be included.

      4. Keep in mind, you are not required to use an internet provider’s phone service. There are a few options here, Jeff. First, you can use your local phone company’s service. Second, you could use a smartphone. If you don’t use phone service a lot, you can purchase a TracFone with one-year of service (1500 minutes) for $60 on eBay.

      Third, you can get away from RCN’s eMTA by using an Ooma device. Ooma uses any internet connection to give you inexpensive phone service (but it is still a VoIP service).

      Fourth, if you don’t want to deal with a power failure for your phone service through any use of VoIP, you can purchase an uninterruptible power supply (UPS); it will power devices connected to it for several minutes or hours depending on the model you purchase. The more devices using juice, the quicker the UPS will fade. Keep in mind, if a tree takes out a power line or phone line, your service will stop anyway. The only way around this is to use a mobile phone (as long as the cellular network is still online).

      Hopefully all that info will help with your situation, Jeff.

  38. Hello,
    Thank you for this amazing resource! I will be moving to Somerville, MA, and switching from Fios fiber to RCN cable 250 Mbps. I am pretty sure I will end up getting the 500 Mbps or 940 Mbps over the next year or so. I will be in a 2000 sqft condo so hoping to get a Modem/WiFi combo in one device instead of getting these separately that will give me good speed and coverage. So far, NETGEAR R7000P-100NAS has been recommended to me.

    Would you be so kind as to make a few suggestions as to which modem/WiFi combo (in one device) I should get that will allow me to bump up the speed in the future without having to buy a new one? Thank you so so much!

  39. Hi. I own a Arris SBG8300 and have been using it with Comcast/Xfinity about a year now. I see it’s listed on the “RCN Approved Modem List” and today I discovered it has the dreaded Intel Puma Chipset. I’ve gotten some confusing info from calling RCN tech person (no you can’t use your own modem/router combo even though the RCN rental is a modem/router combo). Can I use this Arris SBG8300 with RCN internet service? I know it’s got the Intel Puma Chipset but too late, I already own it.

    Reply
    • That tech is just trying to get you to rent a device from RCN most likely. RCN rental fees are steep. Always talk to multiple service reps if you don’t get the answer you want. Yes, the ARRIS SBG8300 should work on RCN’s network. If, for some reason, RCN continues to hassle you about your device, it could be a good opportunity to purchase a non-Intel Puma chipset modem, Michael G.

      Reply
    • It sure will, Mitch. You can use any router you choose for RCN. Only modems are specific to internet providers. In other words, WiFi is not provided by RCN; they only provide internet. Your router provides WiFi.
