Guide to Buying a Modem for Comcast Xfinity

We are very confident that we have put together a good list above. But on the off chance that you actually don’t find what you are looking for, use this guide. There are certain things that you should know about and things that you should definitely have. Better safe than sorry. But we really do hope that you won’t need this part of the article.

Modem  & Router Features

  • LAN ports – Ability to make connections is the basis of any mode of communication. If the modem comes with LAN ports then it becomes easier to hook it up with your computer using an Ethernet cable. Moreover, the port can be used to connect other smart devices to the Modem as well.
  • USB ports – A USB port is a standard feature of any electronic device you can think of. Be it TVs, computers or even modems. But eyes should be on the number and kind of USB ports the device has. Remember to buy something that meets the requirements you need.
  • Quality of Service – The degree to which you can configure the settings of the modem so as to bring it up to your speed matters a lot. Since different people look to accomplish different things using the internet, different customizations are needed.
  • App-Based Management – You can find all kinds of apps in the store that are designed to be used as remotes. This trend has extended to modem management as well with apps that the company itself creates. The main pro is that you will never miss an update alert ever and at the same time you will be able to keep an eye on who is using your wifi network.

Things to keep in mind

  1. The maximum attainable internet speed using your modem – Talk about the internet and the next thing people will talk about is its speed. When it comes to this arena the slow and steady definitely does not win the race. So it is absolutely vital that you need to look for a modem that lets you off with the best possible speed. This means to look for a modem that can actually give you the speed that the company promises.
  2. DOCSIS 3 vs DOCSIS 3.1 – If you have already been looking online for a good modem, chances are that you have come across either one of these and quite often. You might not really know what they mean. But it actually isn’t that complicated. The 3.1 supports a larger number of simultaneous channels and offers higher speeds. But it is a tad bit more expensive than 3. Oh, and DOCSIS stands for Data Over Cable Service for those of you who are still wondering.
  3. Considering a Mesh Network – Ever get annoyed by the fact that you can’t get a strong signal over your favorite lite Chair in the far end of your room? Well, if you do then one solution is to get multiple routers to make a network. So buy a modem that can support as many routers as you need.
  4. Security Setting – You would wanna stay clear of every kind of hacks and virus that can affect your system’s health. In that sense, security settings should be casting around for. Plus, it wouldn’t be the worst thing in the world if you could watch over the people who are entering your WiFi network without you knowing about it.


So there you are. We have given you a glimpse of all the good modems out there. And we have also taken the time to write up a buying guide just in case. So if you are not interested to buy an item from this article, scout one for yourself. Good Luck.
