Can't change wifi channel settings

@XfinityBillie Thanks for your reply. I am using a Xfinity Gateway XB6 and when I look at the router settings in Xfi the settings for wifi channels no longer are available. As I stated I am in a community where all the internet service is Xfinity routers and I need to be able to change the settings because right now I am on channel 11 for 2.4 and so are all my neighbors. If the automatic option was working correctly not everyone would be on the same channel.
 

Thanks for sharing the Xfinity Gateway model. If you take the following steps: 

1. Visit https://comca.st/3cRp3kT or open the Xfinity app, and sign in with your Xfinity ID and password.
2. Select the Connect tab.
3. Select See Network.
4. Select Advanced Settings 

Do you see the 2.4 and 5 GHz WiFi channels available at all? 

No settings for wifi channels
