If the blue blinking light xfinity modem slowly, this means your router is currently in the process of establishing an internet connection. It can take 30-60 seconds for the connection to fully activate after turning on the router or modem. Be patient and wait for the light to stop blinking before assuming there is a problem.

How to fix a blinking blue Xfinity router light

If your xfinity router blue blinking light for more than a few minutes, it’s a good idea to try some troubleshooting steps to get your network back online:

1. Check cable connections

Make sure the coaxial cable from the wall is firmly connected to the “Internet” port on the router. Gently unplug and reseat the cable to rule out a loose connection.

4. Login to the router admin page

Accessing the web portal may provide more details on the connection status. Look for error messages or options to manually re-establish the network link.
