Usually, you can get a stable WiFi connection and don’t have to rely on Ethernet.If the white light is blinking, it means that the connection between your Xfinity router and the internet is not stable and is getting interrupted. Some later Xfinity models have white light with a slight purple tint to them.

Other physical issues include wires not being connected to the ports securely or a problem with the splitter that divides your internet connection between different links.

3. Reset Xfinity Router

Reset Xfinity Router

If restarting your router didn’t work, you can try performing a factory reset. To do this, find the reset button, which is located on the back of the router. Resetting the router means adjusting the router’s settings by either increasing or decreasing until it well fits the environment for use. It is a small, recessed button that is usually a different color than the rest of the router’s body, making it easy to identify.

Using a paper clip or a pen, gently press and hold the button until the lights on the front of the modem go off. It will take a few seconds for your router to reinitialize and the lights to come back on. It is important to note that a factory reset is permanent and will wipe away all previous network settings and configurations, including the WiFi name and password. It means you will have to go through the router activation process all over again.

If none of these solutions did the trick for you, the only option left for you is to reach out to Xfinity customer support via call or email. Customer care provides you with the solutions you can try since most of them work with the Xfinity routers.
