AT&T and Xfinity are two popular telecommunication networks that boast strong internet service and have different yet renowned use in many homes. But what happens if you have an AT&T router and want to switch to Xfinity internet? Can you use a router provided by AT&T with Xfinity internet?

AT&T brand routers cannot support Xfinity internet. This is because AT&T uses DSL and fiber networks, while Xfinity uses coaxial cable networks. However, AT&T-compatible routers can sometimes accommodate Xfinity internet and vice versa.

Having to get a new router to pair with your new Xfinity internet can be a hassle. Fortunately, there are ways to connect some AT&T-compatible routers to Xfinity internet. Keep reading to learn more about how to go about making this connection.

Can I Use My AT&T Router with Xfinity?

Routers provided by AT&T will not work with Xfinity internet. This is due to differences in the way each company connects users to the internet.

While Xfinity connects users with a coaxial cable network, AT&T uses DSL and fiber networks to do the same. Each system offers different internet speeds and modes of connection to devices and wall outlets. For this reason, the plugs and cables used to connect to the internet are entirely different. In that sense, Xfinity internet will not work with AT&T brand routers or gateways.

Compatible Routers for Xfinity Internet

AT&T brand routers, or those provided with AT&T internet service, cannot connect to any internet service than AT&T. However, there are a few third-party routers available online that are compatible with both AT&T internet and Xfinity internet. Some of these include:

Note that AT&T does not make these routers. They are made by various companies and can connect with many internet providers, including AT&T and Xfinity. If you were using one of these routers with your AT&T internet and have since switched to Xfinity, you can still use it to create a wireless connection to your Xfinity network.

Can You Connect Xfinity Routers to the AT&T Gateway?

The routers made by Xfinity itself cannot establish a connection with AT&T gateways. However, third-party routers that are compatible with both Xfinity and AT&T can.

A gateway is a combination of a modem and router in one package. AT&T and Xfinity have their own individual gateways, which can be linked to external routers to create a stronger connection. In this case, you can follow this method to link your Xfinity-compatible router to your AT&T gateway:

  • Connect one end of the Ethernet cable to the internet port on your router.
  • Connect the other end to the yellow Ethernet port on the AT&T gateway.
  • Visit the AT&T website to disable the wireless feature on the gateway. This way, other devices will not interfere with your network.

Again, ensure the router you are trying to use is compatible with both services before attempting to make this connection.

Why Can’t I Connect My Router to Xfinity?

If you are having trouble connecting your router to Xfinity internet or experiencing a slow or inconsistent connection, there are a few troubleshooting tips you can try that may solve the issue. Your first step should be to restart your router or gateway. To do so, follow the steps below:

  • Unplug your router from the power outlet for at least 30 seconds. If your router includes a backup battery, remove this as well.
  • Plug the router back into the power outlet and reinsert any backup batteries you removed.
  • Try connecting to your Xfinity internet to see if the problem has been fixed.

If this doesn’t work, there are a few more in-depth troubleshooting techniques you can try.

Other Troubleshooting Tips to Connect Your Router to Xfinity

If restarting your router did not help your router connect to the internet, there are a few other things you can try. These include:

  • Check if the Ethernet port connection works. A wired connection often provides faster service than a wireless one.
  • Remove any devices connected to both the router. Having too many devices at once can disrupt the network flow.
  • Refer to the router’s manual. Check to see if you missed any important configuration steps.

If you are still having trouble connecting after following all the techniques listed above, contact Xfinity customer service for additional help.

Final Thoughts

Since AT&T and Xfinity have different methods of connecting users to the internet, it is not possible to use an AT&T-provided router with Xfinity internet. However, third-party routers that support both internet providers can be used. Before attempting this connection, refer to your manual or an online product listing to ensure that your router is compatible with both Xfinity and AT&T internet.
