Best Modem Router Combo For Xfinity & Comcast (2022) (2024)

If you subscribe to Comcast Xfinity, you will naturally want the best possible performance. To do this, you will want the best modem router combo for Xfinity that you can get. But, which device is the best one?

When it comes to finding the right device, you will need to think about many different factors, including the speeds, compatibility, and even coverage.

What you need for your network will determine which modem router combo that you should get.

Ultimately, you need a device that is compatible with Comcast Xfinity. Here’s how you can decide which the right one is for your network.

Factors To Consider When Getting A Modem Router For Xfinity

Best Modem Router Combo For Xfinity & Comcast (2022) (1)

WiFi Speed

The first consideration when looking for the best modem router for Xfinity is the WiFi speed. You will need to consider the speed package that you have with Comcast, but you also need to think about what you are doing with your internet at home.

Are you more of a browser than a streamer? Gamers need faster speeds than people who usually stick with social media. All of those factor into the speed.

Wireless Range & Coverage

Another factor to consider when getting a modem router for Xfinity is the range and the amount of coverage that you need. Every device should list what its wireless range is, so you need to compare that to the size of your home.

Think about the amount of walls, rooms, and even floors that the signal will have to travel to. More coverage is always better than less coverage.

Channel Bonding

Channel bonding should also be considered when looking at a modem router combo for Xfinity. Channel bonding is how your modem breaks up your web traffic at a packet level between several internet connections.

The more channels that you have, the more efficient your device will be. Modern cable modems will either have 16 x4 or 32 x 8 channel bonding, with the 32 x 8 being faster. At minimum, you need 16 x 4.

Compatibility

Compatibility also matters greatly when it comes to a modem router combo for Xfinity. Since Comcast is a cable company, you need to make sure that you have a cable modem. With Xfinity Voice, you need a modem that has voice capability.

All of the devices that we reviewed for you are compatible with Xfinity, so if you are looking for a device not listed here, make sure that Comcast says it is compatible.

Features That The Best Modem Router Combo For Comcast Should Have

Best Modem Router Combo For Xfinity & Comcast (2022) (2)

Security Features

The first features that you should look at for Comcast Xfinity is the security features. This can include anything from a firewall to a VPN network.

You will need to think about what kind of protections that your network needs in order to work effectively. Some networks might just need simple parental controls while other networks might need to be HIPAA compliant.

Every modem has different levels of security, so pay close attention to what a modem lists before you go ahead and commit to one. Your needs are different than someone else’s might be, so consider what you really need.

Voice Services

Another feature that you should look for with your cable modem router combo is whether it has voice services. This only matters if you have Comcast Xfinity Voice, which is a telephone service that works through your modem.

Only a few modems come equipped to handle this, so you will need to pay close attention to be sure that you are getting one that will actually work for your needs. If you have a modem that supports voice services, but you do not have Xfinity Voice, you should be fine compatibility-wise. Having a modem with it, means you always have the option to get it.

DOCSIS 3.0 or DOCSIS 3.1 Standard

DOCSIS 3.0 and DOCSIS 3.1 are the cable modem standards right now. The DOCSIS 3.0 was the old standard and is most commonly supported by cable companies.

DOCSIS 3.1 is the update and is much faster, but not all companies can support it yet. DOCSIS 3.1 modems are usually backward compatible, however, so you should still be able to use one even if Comcast is only supporting DOCSIS 3.0.

Either standard will work for the average household, but if you stream heavily, you should check out what DOCSIS 3.1 modem options are out there.

Dual-Band or Tri-Band

Do you need a dual-band or a tri-band router? A dual-band router has a 2.4 GHz band and a 5 GHz band while a tri-band has an additional 5 GHz band. As a result, tri-band routers have better speeds and are capable of a lot more than a dual-band router.

If you are gaming heavily on your router or there is a lot of streaming, you should try to get a tri-band router over a dual-band. If not, you should still aim for a dual-band over a single-band, because there is a huge speed difference between the two.

Firmware Updates

The final consideration that you should make as far as features go is whether the device has firmware updates. Some devices will update themselves automatically, while some other devices require a manual update to go forward.

These can usually be configured in the settings, but not all devices will even have the option to update. Some firmware updates are hard to do manually and will require a level of tech understanding in order to achieve.

Firmware updates will help keep your network safe against new threats and can help do any fixes for errors that might have been discovered after you bought it.

Beamforming

Beamforming is a great feature that you should look for when you are shopping for your modem router combo. Beamforming is a router feature that will allow you to really direct the signal in the areas of your network that need the strongest signals that they can get.

This will increase the overall strength of your signal as it travels through your home, ensuring that you will get the signal strength that you are looking for.

Modem Router Combo For Xfinity vs. Separate Units

When you really start looking for a new modem, you will see that you have the choice of buying a modem router combo or buying separate devices.

The choice for you is a matter of personal preference since both options have benefits.

Pros For Combo Units:

  • Less expensive since it is just one device
  • Takes up less room
  • Simple to update
  • Easy to setup

Pros For Separate Units:

  • More choice in router selection
  • You can update as needed
  • You can always upgrade your router
  • You don’t want a router

For the average network, a combo unit is the best choice, but it does come down to personal preference.

How To Install Your Own Modem Router Combo For Xfinity

  1. Buy a modem router combo that is compatible with Comcast Xfinity.
  2. Start by plugging the coaxial cable from the modem to the cable jack in your wall.
  3. Then, plug the modem into the power outlet.
  4. Next you will need to connect the Ethernet cable from your modem to your computer. The lights should all be on now.
  5. Call Comcast and let them know you are changing gateways so that they can activate the new modem for you. Do not let them tell you that you need to use one of their modems, because that is not true.
  6. After activation, open a browser on your computer and type in the location indicated on your modem’s packaging.
  7. Follow the setup wizard.

Final Words

While there are a lot of great modem router combos that work with Xfinity, we still have a favourite.

Our choice for the best modem router combo for Xfinity is the Motorola MG7550. This device really has everything that a modern network would need in order to run as efficiently as it wants to. Motorola makes reliable devices as well.

Still, if you are after something more high performance, you can look at the Netgear Nighthawk C7800, which is built to handle a lot more activity.

There are a lot of great options out there to work with Comcast Xfinity, so think about what your network needs and then you can decide which is best for you.
