We understand that you may not know all of the devices which are currently connected to your box, luckily there is an easier way to remove unwanted devices.

  5. Removing a few devices from your router can make all of the difference.

However, if your router is still blinking after you’ve removed some devices, we’d recommend checking out our next troubleshooting technique.

Step 4. Assess your cables

Although this may seem obvious, your cables may be in a poor state which can cause errors on your router. Things such as frayed wires, pets chewing cables and loose connections can all cause issues. Check through your cables to see if you can notice any damage.

Check all of your wires are plugged in tightly and there are no knots and frays on the wires. Straighten out the wires, and undo any tangled cables. If you notice any damage to your wires, it may be worth replacing these. You can replace them easily on Amazon or get in touch with Xfinity to request a replacement.

Step 5. Hard reset your Xfinity router

The final troubleshooting technique we recommend is to hard reset your router. Although this should be done as a last resort. As it means resetting your router back to its factory settings. Unfortunately, this does mean any custom names and passwords will be removed. You will also have to sign into the WiFi again on all of your devices.

To hard reset your router you need to do the following:

  1. Head to your router and make sure you can see all around it
  2. Hold the reset button on the back of your router, for 60 seconds then release
  3. Once you release the button the router should begin to restart back up
  4. After this has turned on try to connect again, however, remember you will need to sign in from the credentials on the bottom of your router.

Note: If you have an older router you will need to use a pin to reset your device, as there isn’t a reset button that can be pressed. If you have a pinhole button, the reset steps are the same, the only difference is using a pin rather than pressing a button.
