Why is my Xfinity router blinking blue?

1. It’s connecting to the internet

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.

2. Replace the coaxial cable

Damaged or old cables can cause connection issues. Swap out your cable with a new high-quality coaxial line to see if that resolves the blinking light.

3. Restart the modem and router

Turn both devices off, wait 30 seconds, then turn them back on. This refreshes the connection and can sometimes fix small glitches.

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.

5. Contact Xfinity support

If restarting doesn’t work, call Comcast and provide the exact light pattern you’re seeing. A technician can diagnose line issues or problems with your account.
