Comcast Xfinity Compatible Modems (2020 List)

Unless you don't mind paying Comcast for something you don't even own, there is no reason to give them your money when you could be putting it to something better.

We are referring to the $10 a month charge to rent a modem from Comcast, when you can save yourself money and trouble and just buy your own Xfinity compatible modem.

Getting your own Comcast approved modem is economical, easier, and frankly more practical than using the generic modem that Comcast would be happy to rent to you.

Here's Why You Need To Get Your Own Comcast Compatible Modem

Comcast Xfinity Compatible Modems List

Save Money On Rental Fees

Do you really want to pay Comcast $10 a month (or $120 a year) to rent their modem? No other Xfinity approved modem is going to continually cost you money, so there is no reason to let Comcast profit off of you.

Buy your own modem and save yourself some money. As an added bonus, you can get a modem that you actually want and get to keep rather than whatever Comcast decides you should have.

Faster Internet Connection

We all are dependent on having the fastest internet possible, which you are unlikely to get from Xfinity’s rental modem. Instead, we recommend you buy your own Xfinity approved modem in order to get the fastest connection possible.

The rental modem will not take into consideration how many devices you use and the amount of streaming that you do, so there is no way their modem will be able to accommodate your speeds.

Better Wireless Coverage

It is obnoxious to find yourself losing your wireless connection as you move throughout your home. In one room, you might have a strong signal, but in another, it could be completely dead.

When you buy your own modem, you can confirm that the modem will reach across your entire living space. There’s no guarantee that Comcast’s modem has the type of coverage that you really need.

Why It's Usually Better & Easier To Get A Modem Router Combo

There is no good reason to buy a modem and router separately.

  • One Unit to Update: Imagine having to check for firmware updates for two devices instead of one. It’s a hassle. Add in that updates will not happen at the same time and you will find that you have given yourself an unneeded headache that you wouldn’t get with a combo unit.

  • One Unit to Figure Out: If you have a problem with your internet, you do not want to first try to work out whether it is your router, modem, or something else. Take the complication out of the equation and just worry about one unit.

Installing Your New Modem Step By Step

  • Start by plugging the modem into the power outlet.
  • Then, plug the coaxial cable from the modem to the cable jack in your wall.
  • Next you will need to connect the Ethernet cable from your modem to your computer. The lights should all be on now.
  • Open a browser on your computer and type in the location indicated on your modem’s packaging.
  • Follow the setup wizard.

1. Motorola MG7550 Modem Router Combo

Best Comcast Approved Modem (Editor's Choice)

We want you to have the best modem that you can get for Xfinity, which is why we are recommending the Motorola MG7550. You really can get anything that you need from this modem.

The MG7550 is an advanced DOCSIS 3.0 cable modem. It comes with a built-in AC1900 dual-band router as well, keeping up with the high speeds that you want to get from your router. The router also has Power Boost, which provides high speed internet access for any wireless device in your network, from tablets and phones, to Amazon Echo and Google Home.

Beyond, the amazing router, the MG7550 comes with four Gigabit Ethernet ports, a firewall, and a Broadcom cable modem chipset (as in not Intel) for extra security for your network. You have plenty of space to wire in any device that needs uninterrupted coverage.

2. Netgear C7500 WiFi Modem Router

High Performance Xfinity Compatible Modem

When your network needs that high performance modem, you should never settle for anything less than the best. This is why we recommend the Nighthawk C7500-100NAS for the best high performance modem.

The Nighthawk is more than your average modem, with a built-in router and a 4 Gigabit Wired Switch. It also has a DOCSIS 3.0, showing you that this modem has a lot of offer. This is a great choice if your network is going to be doing some heavy streaming from multiple devices, whether you are watching videos or gaming.

Another added touch from the Nighthawk is that it has four antennas, which you will not find with many other modems of this quality. The antennas might not be the most attractive or easiest to conceal, but they do make your modem look like a spaceship and give you a more powerful signal across the whole network.

3. Motorola MG7540 Modem Router Combo

Budget Friendly

Whether money is tight or you just prefer to be more conservative with your spending, you should not settle for a garbage-level modem when you can get a high-level modem at a more reasonable price. That is why we recommend the Motorola MG7540 for Xfinity users on a budget.

This budget friendly modem comes with AnyBeam Beamforming, which means that you can focus your WiFi at the devices that need uninterrupted connection and no buffering. This is also a dual band mode, so you will have the best speeds you can get on your network.

The built-in router is an AC1600, so it is an excellent choice. The DOCSIS3.0 modem has four Gigabit 10/100/1000 Ethernet ports as well, so it really should be able to handle any device that you have in your network. The ports mean that you can wire in any device that you want to, from HDTVs to an Xbox One.
