Xfinity Router or Modem Blinking Blue: What It Means

If your Xfinity router or modem is blinking blue, the gateway is in WPS mode, which is short for WiFi Protected Setup. Xfinity's own chart says a blinking blue light means the gateway is trying to connect with another wireless device, and that once the connection is made, the new device should be up and running. That makes this one of the least worrying lights.

Why is my Xfinity gateway blinking blue?

WPS mode starts when you press the WPS button on the gateway, when an app or device asks the gateway to pair, or during some setup flows. The gateway then waits for a device for a short window. While it waits, the light blinks blue.

Situation What you will see What to do
You just pressed WPS or are pairing Blinking blue Finish pairing on the device
Nobody started pairing Blinking blue Wait for the window to end, or restart the gateway
Blue does not stop and internet is down Blinking blue Check other lights, outage status and restart

How to finish pairing

  1. Start pairing on the device you want to connect (for example, choose WPS or the pairing option in its settings).

  2. Keep the device near the gateway.

  3. Wait for the light to turn steady white.

How to stop a blue light you did not start

Wait a couple of minutes for the pairing window to end. If the light is still blinking, restart the gateway with the Xfinity app or by unplugging it for 60 seconds. After it restarts, the light should cycle through the normal startup colors and settle on steady white.

If blinking blue comes with no internet

Blue relates to WPS, not the connection to Xfinity. If your internet is down, check for an outage in the Xfinity app, tighten the coax cable and restart the gateway. Read our Xfinity gateway lights guide for the other colors, and see Xfinity WiFi not working if the problem continues.

The bottom line

Blinking blue means pairing, not a fault. Finish or wait out the pairing window, and restart the gateway if it does not clear.

Frequently asked questions about xfinity router blinking blue

Why is my Xfinity router blinking blue?

Xfinity lists a blinking blue light as WPS mode: the gateway is trying to connect to another wireless device. It stops when pairing succeeds or times out.

How do I stop the blue light from blinking?

Wait for the pairing window to end, or finish pairing the device. If it keeps blinking, restart the gateway.

Is a blinking blue light a problem?

No, it is not an error. It signals a pairing attempt. Only investigate if the gateway stays blue and you have no internet.

Does blinking blue mean my internet is down?

No. It relates to WPS pairing, not the internet connection. Check the light again after pairing completes.

Can a blinking blue Xfinity light be triggered by accident?

Yes. Pressing the WPS button on the gateway, or triggering pairing from a device, starts WPS mode.
