You must first decide what kind of router you want. Next, make sure the router is compatible with Xfinity. 

To create this list, we looked into a wide range of manufacturer claims, model specs, peer experiences, and user impressions. Then, we chose our top five candidates.


Reviews, compliance with at least the very minimum criteria, and user-generated reports can provide valuable insight into a router’s general operation. 


Once you’ve reduced your options to a few, fewer considerations can assist you in making your decision.

Do I need a modem and router combination?

You connect to the internet service provided by Xfinity via a modem. Thanks to a router, your gadgets may access the internet from anywhere in your home. Without a modem, the use of the best router is minimal to nonexistent. If you purchase a router without a modem, you will be left with a box that provides access, the same as opening the door to a brick wall fi router.

Because you get everything you require in a single piece of equipment, some people choose modem-router combinations. Confirm compatibility, either from the manufacturer or through the Xfinity website, to prevent disappointment.


Based on the maximum speed they can produce, routers are rated. So, first, find the ideal internet speed for you, then choose a router with a maximum speed that is somewhat over but not much above that speed (after all, why pay for something you won’t use?).

The “Data Over Cable Services Interface Specification,” also known as DOCSIS, is the following factor you must consider. The ability of the internet to move from the modem component of the combo to the router component determines how strongly this element influences your download speed.

You’ll need to be concerned with DOCSIS 3.0 and DOCSIS 3.1, two different types of DOCSIS. DOCSIS 3.0 can deliver download rates of up to 1 Gbps and upload speeds of up to 200 Mbps. Conversely, the 2 Gbps upload and 10 Gbps download speeds of DOCSIS 3.1.

Wi-Fi protocol

While looking for a router, you may hear about one of three Wi-Fi standards. The three are Wi-Fi 5, Wi-Fi 6, and Wi-Fi 6E, in order of most to least widespread.

Most routers use the Wi-Fi 5 standard, which offers up to 3.5 Gbps. Around 2011, it was first presented.

Wi-Fi 6: To summarize everything we’ve written in-depth on Wi-Fi 6: 2019 saw the launch of Wi-Fi 6, which supports multi-gigabit internet rates. It can simultaneously manage many network devices, such as smart speakers and light switches. In addition, Wi-Fi 6 routers offer a more extended range and next-generation security methods like WPA3.

Wi-Fi 6E: Wi-Fi 6E is an updated version of Wi-Fi 6, with the “Enhanced” prefix. For devices to be future-proof, it’s crucial to comprehend Wi-Fi 6E. Therefore, one of our top selections for the best Wi-Fi 6 routers should be sufficient if you want something that will last for many years.


The type of router you’re using, the wireless protocol the router uses, and the area you’re in all affect the Wi-Fi range. For example, if you need long-distance Wi-Fi, 2.4 GHz Wi-Fi routers should be used because they range up to 150 feet within and 300 feet outside. 

You should choose a 5 GHz router for speed, but only if your devices can be placed closer to your internet access point. This is because 5 GHz routers can reach around one-third of these distances. After all, they employ narrower wavelengths. 

More modern routers use the 2.4 GHz and 5 GHz bands to cover more expansive areas and provide the highest throughput for devices closer to the router of the compatible modem.

The signal can be weakened by walls, electronics, and certain other items between your device and the router (which is why we’ve put together a helpful guide on Wi-Fi extenders).

The top Xfinity routers alleviate consumer problems while improving the overall user experience. Therefore, our suggestions concentrate on the most satisfactory solutions that are mainly future-proof but are compatible with more antiquated hardware and software.
