Ethernet Cables

While a purchased modem may include an Ethernet cable, it may be too short, the wrong color, or the wrong category cable. Ethernet cables get split into different categories ranging from Category 5 to Category 8 (Category 8 being the best in terms of performance). See the differences in the table below.

Coaxial Cable Splitters

Most people require the use of a coaxial cable splitter due to having only one coaxial connection or the fact they need multiple devices connected (cable boxes and a modem, for example).

A coaxial cable splitter splits off one cable into multiple cable outputs.

Modem Fans

Worried your modem is feeling too warm? Purchase a modem fan to help keep it cool. Modems are usually reliable as long as they do not overheat. You may even use these devices on a router.

Surge Protectors

Keep your expensive equipment safe from surges. A quality surge protector can save you money in the long run. Pro tip: get a surge protector with coaxial, telephone, and Ethernet protection to protect from surges that occur through more than just your electrical outlets.

UPS (Uninterruptible Power Supply)

An easy way to lose valuable data on a hard drive is to lose power while the drive is in use. Combat this problem with a UPS and have the time to properly shut down your equipment.

An uninterruptible power supply contains a battery that will switch on automatically when there is a power outage. The device gives you several minutes of operating time to continue using your equipment (depending on the model of UPS and how many devices are draining the battery).

Pro tip: get a UPS protector with Ethernet, coaxial, and telephone protection to protect from surges that occur through more than just your electrical outlets.

Cord Management

Keep your area tidy by wrapping up loose cords into a bundle instead of messy wires running everywhere. You may use VELCRO straps, plastic cable ties, twist ties, cable clips, and more to help with cord management.

Network Switches

A network switch may be your solution if you require more than one Ethernet cable connection. A switch may be needed if you do not want to deal with the hassle of poor connections using WiFi. Or, if you want the fastest possible internet speed using a wired connection, a network switch can offer several Ethernet connection points.

  1. Is there a listing available which identifies which cable motems and routers are MOCA compatable supporting either Verizon & Comcast
    or perhaps both ISP’s ?

    Thank you !

  2. Do you ever get any input from your readers about which seems to be the best 2-way splitter on the market?
    Or, do you have an opinion about which is the best splitter on the market for cable modems?

      • Must be the gold color and gold plated connectors, otherwise I’ve read where other brands are rated higher on many other websites that rate splitters.
        I do not always trust and believe 5 star reviews as many reviews could most likely be false and misrepresented of the product and especially on Ama..n.

        • True, some reviews on Amazon are fake. But when an item has 8,000+ reviews, some have to be legit reviews. When an item only has 30 reviews, those are more likely to be less reliable as legit reviews. Feel free to chose the splitter that appeals to you for your needs, Jeff.
