Xfinity router blinking blue: 5 Fixes

Comcast’s Xfinity routers are as much susceptible to bugs and issues as any other piece of hardware. We’ve already covered why your Xfinity router is blinking orange or blinking green and what you can do to fix the issue in a jiffy.

Another commonly reported issue with Xfinity routers is the flashing blue light. The primary reason your Xfinity router is blinking blue is that the WPS mode is activated, allowing nearby devices to connect without entering the password.

Now, if you haven’t activated the WPS or the light won’t stop blinking even after the device is connected, chances are that it’s a software or hardware bug.

Here we’ve discussed five ways to fix the Xfinity router blinking blue light issue.

Restart WPS

Since the primary reason the blue light blinks on your Xfinity router is the WPS mode, try pressing the WPS button to see if that stops the blinking. You can also try pressing and holding the WPS button to see if that makes a difference. If it doesn’t, move on to the next step.


Restart the router

If it’s been far too long for the router to be updating, you should restart your router. Restarting internet devices can fix seemingly random issues that cause connectivity problems, including the Xfinity router blinking blue issue. Just turn off your router (and modem) and wait for a few minutes before turning it back on again. 


Check the splitter

Xfinity will usually install a splitter alongside your internet connection that ‘splits’ the connection into WiFi, TV and phone. If there’s a problem with this splitter, it can impact the inbound internet signals to your router. Check to see if the splitter is functioning properly and now showing signs of defects, including overheating and mechanical damage.

Check the cables

The next thing to do is check to see if the splitter, the incoming WAN cable and any other inbound connections to your router are intact. Regular wear and tear can damage the cable carrying WAN signals to your router causing internet issues. 

If you see any damage to any inbound connections, including any cuts and breaks, reach out to your ISP for support and get them to fix the cables. 


Contact Xfinity support

Finally, if nothing else works, you will have to contact Xfinity support and have them assist you remotely or send a technician over to your house to diagnose and fix the problem. There’s a good chance that the issue actually persists in your router, and a replacement from the ISP would be able to fix the problem.
