Comcast Lies About WiFi

Comcast's documentation says you can turn off the Xfinity public WiFi on your gateway (https://www.xfinity.com/support/articles/xfinity-wifi-hotspots), but you can't. The instructions don't work and Xfinity assistant techs aren't allowed to turn it off.

It's really annoying having that gateway trying to outcompete my own WiFi APs.
