Disabling PublicWifi/XFINITY WiFi
After reading the woes of several customers here in the forums, I called Comcast to get the public Wifi disabled.
The tech support guy at Comcast disabled XFINITY Wifi (Public Wifi) for my gateway. Sure enough, I stopped seeing the xfinitywifi network immediately.
However, after I power cycled the modem (model DPC3939B), the xfinitywifi returned again. I still had the Comcast guy on the phone. He once again disabled the Public WiFi.
I am hoping the Public Wifi does not return. I hope I do not have to power cycle the modem, because the setting to disable the Public Wifi in the modem is not persistent? I suspect the modem re-enables Public Wifi at every power up. The Comcast guy could not deny that either.
Is the solution then to use another Comcast modem without Wifi ? Then use my own Wifi router.
