1. Check WiFi Cables – External Problems
Xfinity provides an internet connection to your router via a medium of wires, most probably fiber optic cables. You need to check such cables properly because the internet is cut if any wire is broken. The lights on the router might be blinking with a proper power supply but the internet won’t work in such cases.
Not only in your home network, any breakage of cable in your entire area due to accidents or natural calamities like wind, storm, etc. can cause the issues. Therefore, you need to do some research on the points where it could be broken and fix them or call the authorities if the whole area is down.
2. Restart router
Restarting the router manually or virtually will sometimes help to fix the Comcast DNS server not responding 2021 error. For manually, you need to unplug the router’s adapter from the power source and then plug it back in after waiting for at least 10-20 seconds. The router will then take some time around 5-10 minutes to restart.
To perform this action virtually, you’ll need to download the Xfinity mobile app and follow the instructions listed below.
- Open the Xfinity app on your android or iOS device.

After that, make sure that there's no device overloading on your network based on the internet plan that you've subscribed to.
