What 3.1 modems does mediacom support? Why do I need to rent 3.1 modem from you and have you install?
Upload speeds with mediacom are very slow.
Hello Mike,
First of all, Mediacom does not operate this site. You will need to contact them for support issues (side note, you do not need to rent a modem – buy your own modem to save money). ApprovedModemList.com is a site that pulls information on certified modems for ISPs. The point of this website is to save people money on purchasing their own modems instead of renting, which is a big waste of dollars.
As for the DOCSIS 3.1 modems Mediacom supports, please check the list below. These modems are also indicated in the the list above with a * after the modem model #.
ARRIS SB8200
Motorola MB8600
NETGEAR CM1000
NETGEAR CM1100
Thanks for the question, Mike.
I have Mediacom and want to buy my own modem/router with VoIP and WiFi capabilities, are their any available that I can purchase?
On Mediacom’s approved modem list, they state Mediacom phone service will not work on these devices. Mediacom also states that their modem list is not all-inclusive, meaning you could purchase a NETGEAR CM1150V, however it may not work. Contact Mediacom directly with your address to be notified of any voice modems that may work in your area.
Thanks for the question, Julius.
I have a Netgear Nighthawk X6
AC 3200 Tri-Band WiFi Router. Model R8000.
Will this replace my modem from mediacom and my old router ?
Sorry, Robert, but the NETGEAR Nighthawk X6 R8000 Smart WiFi Router is only a router. You will still need a modem to access your internet. You may chose to purchase your own Mediacom approved modem listed on this page.
I need a modem with voice or phone service that will work with Mediacom system. I just bought a arris T25 modem- will it work?
Hello Tom,
The ARRIS T25 contains an Intel Puma 6 chipset, which may perform poorly for you. The T25 may work for your needs with Mediacom, but they want you to contact them directly via Twitter or by phone 1-855-633-4226 so they can notify you of what voice modems will work at your address. Free advice for you, Tom, try to avoid the modems listed on the bad Intel Puma chipset list.
