Xb8 and 2.4 Ghz connection issues

Have tried all of the recommendations including splitting the bands with separate names and security settings. None of my 2.4Ghz devices can find the xb8 gateway even when manually entering the 2.4 band name and password. The xb8 will not even broadcast the 2.4Ghz band on the WiFi list.

Have you first tried power-cycling / re-starting the device by unplugging it for a minute ? Still no joy ? Try hard resetting the device to factory defaults by pressing and holding in the recessed reset button on the rear (or use the WPS button if it doesn't have a reset button hole) for 25-30 seconds. This can sometimes clear up some weird behavior issues. You will lose any customized settings, and they will need to be re-configured from scratch if you do the latter.

Tried all that nothing works. Read comments from Xfinity techs that the xb8 gateway will never connect properly to a 2.4Ghz device.

We really appreciate you sticking with this and trying all of those steps. You’ve definitely done everything I would normally recommend at this stage. I also want to clear up the information you came across. Your XB8 is fully capable of supporting 2.4 GHz devices, and it should absolutely be broadcasting that band. What you're experiencing isn’t expected behavior. Given that:
  • You’ve already split the bands
  • Restarted and tested multiple times
  • And the 2.4 GHz network still isn’t showing at all

This points to something more specific with the gateway itself or how that band is being broadcast. Since a reset didn’t resolve it, the next step here would be to take a closer look at the equipment and signal directly. At this point, we’ll likely need to either:

  • Review the gateway for a possible replacement, or
  • Get a technician involved to inspect things on-site and confirm everything is working properly

I don’t want you continuing to troubleshoot something that should already be working out of the box. We’ll stay with you on this and help get it resolved, whether that means replacing the gateway or getting the right support out to you. To get started, please send us a direct message. Here are the detailed steps to direct message us:

  5. As you type, a drop-down list will appear. Select "Xfinity Support" from that list.
  6. An "Xfinity Support" graphic will replace the "To:" line.
  7. Type your message in the text area near the bottom of the window.
  8. Press Enter to send it.
