Xfinity Gateway 2.4GHz 40MHz channel width by default, is bad.

Just installed Internet Essentials Xfinity Gateway at my Grandmother’s and in reviewing the settings, noticed the 2.4GHz radio is set to 40MHz channel width by default. I have a friend who has the WiFi 6 Xfinity Gateway and has been having issues with Bluetooth and 2.4GHz wireless Keyboard & Mouse interference. Which is likely due to this default configuration of the 2.4GHz channel width. It is recommended to only use 20MHz channel width on 2.4GHz WiFi. If all Xfinity Gateway’s are configured for 40MHz channel width on the 2.4Ghz radio, then a firmware update to fix this is in order.
