Is this a new service install / new move in ? Are you sure that there is a live Comcast feed / line to the premises ?

Hello, @user_lx0snc! Thanks for reaching out with your equipment and service concerns. You've come to a great place for support! Our team is available 7 days a week and remains happy to help in any way we can :) A blinking yellow light on your Xfinity Gateway, especially during a first-time setup, usually indicates that the gateway is having trouble establishing a connection with the Xfinity network. This means it's not receiving a proper signal to get online.

 

Here's a breakdown of what to do:

 

1. Understand What Blinking Yellow Means:

- No Connection: The primary reason for a blinking yellow light during setup is that the gateway isn't able to connect to Xfinity's systems.

- Firmware Update: Less common during initial setup, but a blinking yellow light can also indicate the gateway is updating its firmware. This usually resolves itself within 15 minutes.

- Hardware/Software Problem: In some cases, it could point to an internal issue with the gateway itself.

2. Troubleshooting Steps (in order):

- Be Patient: If you just plugged it in, give it 15-30 minutes. Sometimes it takes a while for the gateway to boot up, find the signal, and activate.

- Check All Cable Connections:

Coaxial Cable: Ensure the coaxial cable (the one that screws into the wall and the back of the gateway) is securely tightened at both ends. This is a common culprit.

Power Cable: Make sure the power cable is firmly plugged into the gateway and a working electrical outlet. Try a different outlet if possible.

- Restart Your Gateway (Power Cycle):

Unplug the power cord from the back of your Xfinity Gateway.

Wait for at least 60 seconds (a full minute).

Plug the power cord back in.

Allow the gateway several minutes to restart and try to connect.

- Try Different Coaxial Outlets: If your home has multiple coaxial outlets, try plugging the gateway into a different one. It's possible the one you're using isn't active or has a poor signal.

- Check for Service Interruptions: We may be experiencing a service interruption in your area.

You can check for interruptions using the Xfinity app or by visiting the Xfinity status page on our website (if you have access to another internet connection, like mobile data).

- Use the Xfinity App:

Download and open the Xfinity app on your smartphone or tablet.

Sign in with your Xfinity ID and password.

The app often has troubleshooting tools and can help you activate your gateway or detect issues. Look for options like "Troubleshoot" or "Restart Gateway."

- Factory Reset (Last Resort for Self-Troubleshooting):

Locate the small "Reset" button on the back of your gateway (you might need a paperclip to press it).

Press and hold the reset button for about 10-15 seconds.

This will restore the gateway to its default settings. You'll then need to go through the initial setup process again.

 

Please let us know if any of this helps! Otherwise, we may have to take a closer look, which we're happy to do.
