If you have had enough and are fed up with spending hundreds of dollars every year to pay your internet provider, this article is precisely what you need!

Generally, internet providers charge around $10-$15 monthly to lease an all-in-one router and modem, which costs more than $360 yearly. Considering this surprising cost, purchasing a modem router combo seems logical. Moreover, it will be more practical, and you will not have to stress over any additional fees charged by your ISP.

Xfinity provides three services: cable TV, internet, and phone. Buying the best modem router for Xfinity will give you a boost in speed, and it is also cost-friendly.

To help you make the right purchase decision, we’ve reviewed some of the best modem router for Xfinity in this article. Have a look!

What to consider before purchasing a modem router combo

Selecting the correct modem router will optimize the provider plan, enhance download speeds so you can view and stream in high definition (HD), as well as link numerous devices in your home at once.

If you want to streamline your internet setup and avoid the trouble of dealing with numerous devices, a modem router combo is the way to go, mainly if you work from home.

To choose the right modem router combos, you must know a few details.

what is modem router combo


To take the maximum advantage of the bandwidth provided by your ISP, you will require a modem router combo that matches, and ideally surpasses, the highest speed promised by your provider. The maximum bandwidth is demonstrated in gigabits per second (Gbps) and is normally shown in a modem or router’s label title or description.


The first and foremost thing to consider when purchasing a modem router combo is the safety and security of the cable modem. It should be able to protect you from others trying to hack the server.

Good Range

Make sure the modem router combo has a strong signal range that reaches every room in your home. It will be pointless to have the fastest speed when you do not have the signal all over the house. Check how many antennas the modem router combo has and ask the company about the strength of the signal. Most of the time, you will find this information in people’s reviews. You will always have some spots in the apartment or house that will not receive a signal, but finding a router with a good range will help.


Another essential element is internet speed. Assess the full download and upload internet speed you can obtain. If you like to stream HD movies or videos often or are a gamer, fast speed is your topmost priority. You would want to purchase a modem and router combo to handle and support faster speeds.


The most important feature to most people is the price tag. However, it is essential to remember that cheaper combos do not always mean a smaller range or worse products, just like expensive combos do not always mean the best speed and good range. Do proper research!


Cable internet providers have largely embraced DOCSIS technology to enable quick, highly efficient, and reliable internet speeds. Nowadays, almost all modems in the market are either DOCSIS 3.0 or DOCSIS 3.1. The difference between these two is that DOCSIS 3.1 offers internet speeds up to 10 Gbps while DOCSIS 3.0 only delivers speeds up to 1 Gbps. Normally, DOCSIS 3.0 is enough if speed is not essential for you.
