We weren’t looking for a modem that would work with a certain network provider; therefore, compatibility with various providers was the first item we looked at. We evaluated each modem’s compatibility and made sure it was generally accepted by popular ISPs while testing it.

Even when buying a low-cost modem, the device’s performance is always the most crucial factor to consider. The performance includes the modem’s speed handling and network stability. So we checked each of these aspects to ensure the modem performs as expected.


Nobody would just throw money without ensuring that the modem works for a specified period since we were short on time to use each modem and check its reliability. We went through the reviews of past customers about how reliably each modem works.


Purchasing a modem isn’t just for connecting to the internet, especially when you’re spending a good amount on it. However, the value also includes specific features for optimal use. Therefore, we made certain that each modem provides a fair value for the price.

Things to Look for in a DOCSIS 3.1 Modem

If you’re a less-techy person, then you might not be familiar with all the technical stuff of a modem. Therefore, avoid throwing your money down the drain and randomly grabbing a modem that won’t work for you. Consider the following factors to ensure that the modem best fits your network.


The first thing to check when purchasing a modem is its compatibility with your network provider. Each service provider has its criteria for approving a modem to work with its network. Thus, before checking anything else, check out your ISP’s website to see if the modem is present on their compatibility list.

The next thing is to make certain what type of modem you’re looking for. It can be a standalone cable modem or a modem-router combo (gateway). If you want full control over your network configuration, a standalone modem should be your choice. 

Otherwise, with a modem-router combo, you can avoid the hassle of buying a separate router to complete your connection. However, standalone modems still work better as compared to gateways, where the router part often suffers in performance.


Purchasing your own modem may appear to be a risk. Because you’re spending quite an amount, and what if it doesn’t turn out to be reliable enough? Warranty is a significant factor when determining a modem’s reliability. So lookout for a long period of warranty to rest assured that you wouldn’t be at a loss if something goes wrong.


This also affects the performance of your modem. So make sure the modem has LED lights to show the modem’s functioning, vents to keep the device cool, and Ethernet ports to connect to other devices for faster speeds through an Ethernet cable.
