Introduction: What Is a Cable Modem?
A cable modem is needed to connect to a cable providers’ Internet network. It receives the Internet signal via a coax wire connected to the modem. Most cable companies strive to lease a modem so they can continuously charge an additional fee each month. However, you can buy your own to forgo this never-ending fee cycle. It’s actually an FCC law that each company allow you to buy your own cable modem. Charter Communications was actually fined by the FCC a few years ago for preventing customers from using their own. There are three different types of cable modems. They are as follows.
- Stand-Alone Cable Modems
- A stand-alone cable modem receives the cable Internet signal from your provider. From there, the signal can be sent via an Ethernet cable to ONE device. That can either be a PC or game system. Additionally, a router can be connected to add more wired ports and wireless signal to multiple devices. This is the most typical in today’s high demand for in home WiFi. Most believe that this is the best choice when buying a new cable modem. A separate router can work better with increased speeds and greater distances. Also, with two separate units, if one burns out down the road, it’s cheaper to replace an individual device.
- WiFi Cable Modem / Cable Modem Router Combo / Gateway
- WiFi Cable Modem – Commonly referred to as a modem / router combo.With a WiFi modem, the router is build-in and offers an all-in-one unit. It typically has four wired Ethernet ports and can support multiple wireless devices in the home. These are more expensive because you don’t have to buy a separate router.
- Voice Modem / Telephony Modem / eMTA
- As with the aforementioned modems, a telephony modem can have a built-in router or be used with a separate router. Only some cable companies allow the use of third-party eMTA modems, so be sure to check on your provider’s page here. This rule doesn’t apply to the FCC regulations due to the sophistication of the modems and how they are set up by each provider.

Tips For Buying A New Modem
- When buying a replacement modem, you should always buy new. Used modems are too often returned because the provider cannot activate it. Most of the time the modem is registered to another provider or user and can’t be undone. Some used modems belong to cable companies and are reported as stolen often.
- Always buy from a reputable seller, such as directly from Amazon or authorized third-party sellers. This ensures that you will be able to register any equipment for warranties and/or replacements shall any issues arise.
- Be sure you are at least getting a DOCSIS 3.0 approved modem. This is the most widely used form of DOCSIS today. However, DOCSIS 3.1 is taking off. Most companies require a 3.0 or higher. Anything less will hinder the speed of your internet if the provider acknowledges it all.
- Be sure the cable modem can support the speed that you subscribe to from your ISP. If you are unsure of your speed tier, you can find this info on your bill.
- Select a modem that has enough download channels to support the same speed. This is often a requirement from your provider. You will see this written most of the time as 32×8 (or different numbers), with the first number being download channels and the second upload channels. This is often referred to as channel bonding.
- Decide if you want a separate modem and router, one with a built-in router or an eMTA unit.
