It is important to ensure that, things like microwave ovens, cordless phones, baby monitors, wireless speakers, and gaming consoles can all potentially interfere with your router’s wireless signal.

Therefore, try moving the router further away from these devices or turning them off when not in use to see if the green light returns to solid.

Change the channel

Just like radio stations, Wi-Fi routers transmit on specific channels or frequencies.

It is possible your router may be on the same channel as one of your neighbors, creating interference and lead to Xfinity green light blinking.

Therefore, you can sign in into your Xfinity router settings and manually change the channel to one that is less congested in your area. Channels 1, 6 or 11 are often good options to try.

Turn off Wi-Fi extender

Firstly, if you are using a Wi-Fi range extender to boost your Xfinity signal in parts of the home, try temporarily turning it off.

It is important to ensure that Wi-Fi extenders work by rebroadcasting your router’s wireless signal, which can potentially lead to interference.

Therefore, see if the Xfinity green light returns to solid when the extender is powered off.

You may need to reposition the extender further from the router to prevent future interference.

Consider a Wi-Fi mesh system

As a last resort, you may need to upgrade to an Xfinity xFi Wi-Fi mesh system to blanket your entire home in fast, reliable Wi-Fi without dead spots or interference.

Mesh systems in Xfinity WiFi are a group of devices that work together to create a single, seamless WiFi network throughout your home.

The devices, called nodes, are connected to each other wireless, so there are no unsightly cables running through your home.

Mesh systems are a great way to improve WiFi coverage in large homes or homes with thick walls.

They can also help reduce WiFi dead zones, which are areas where the signal is too weak for your device to connect.

The xFi pods utilize a dedicated wireless band just for communication between the pods, eliminating the interference issues you are currently experiencing.

Wi-Fi Channel Congestion

Wi-Fi channels can get crowded in neighborhoods, especially apartment buildings. This channel congestion may be the reason your Xfinity green light is blinking.

It is important to ensure that when too many Wi-Fi networks are operating on the same or neighboring channels, it can slow down your internet speed and reduce range.

Switch to a Less Crowded Channel

The solution is to switch your Wi-Fi router to a channel that has less interference from other networks.

It is important to ensure that Xfinity routers default to channel 11, so try changing to channel 1, 6 or 11 which are typically the least congested. Here is some steps mentioned below to change your Wi-Fi channel:

  • Firstly, log in to your Xfinity router settings by entering in your web browser address bar. Enter your router username and password when prompted.
  • Secondly, select “Wireless” or “Wi-Fi” in the left menu. This will open the wireless network settings.
  • Thirdly, choose “Channel” or “Wi-Fi Channel” and select 1, 6 or 11 from the drop-down list.
  • Fourthly, click “Save Settings” or “Apply” to make the change. Your router will restart to apply the new channel.
  • Lastly, once your router has restarted, you may need to reconnect your wireless devices to the network. The new Wi-Fi channel should provide faster speeds and a stronger signal.

If changing channels doesn’t seem to help you can try to use the 5 GHz WI-Fi band instead of the more common 2.4 GHz band. The 5 GHz band is generally less prone to interference.

Therefore, changing your Wi-Fi channel is an easy first step to try and should resolve most channel congestion problems, getting your Xfinity router’s light glowing solid green once again.
