Causes for Xfinity Router Blinking Green

The router may blink green due to clogging if the router and cables are unused for a long time or uncleaned.

  • XFINITY also provides Chat Support. You can get the status of the service outages by chatting with their team personnel.

#2) Hardware Malfunction: Due to wear and tear of electronic and electrical devices like routers, cables, and splitters, there is a possibility of malfunction, or devices may encounter intermittent disconnection. To overcome such issues, you need to check for any cuts or damage to the accessories.

If you are not aware of this process, then you can contact the XFINITY support team. Also, sometimes the power outlet may not work as per standards, so you need to try placing the device into other power outlets to check whether the issue persists. 

#3) Updating Firmware: If the router is updating the firmware, then it can display a blinking green light. You can wait for the update to complete, and you can check the firmware status by logging into the router admin panel. 

If the router gets stuck while updating its firmware, then you need to restart the router (switch it off and on). The router updates the firmware itself, but sometimes, due to software corruption, it may get stuck. In such a scenario, you can contact the XFINITY team to resolve the issue.

Restarting the router means the router will shut down and will start up after a few minutes.

The best way to perform this activity is to switch OFF manually and ON the power switch of the router. You can also restart the router through the XFINITY app by navigating to Connection Trouble -> Restart gateway.

#5) Overheating or Overloading: When you connect more devices to your router above its prescribed connection limits, the router may try to serve all devices, resulting in overuse and overheating. You can switch OFF the router and disconnect some devices, and then try switching it ON.

Sometimes, even dust clogging in ports, loose cables, etc., can also create connectivity issues, so keeping them clean and tidy will help avoid the occurrence of such router issues.

The above steps will surely help to resolve the Xfinity router blinking green and let you connect to the Xfinity service to browse the internet.
