Changing bridge setting cuts off internet
I have a DPC3941. Newly set up. I prefer to operate it without the WiFi on, and only turn it on when company comes. I can log into the router, and access the bridge. If I enable the bridge, to turn off the WiFi, I lose internet connection. And I also lose my connection to the modem. That is annoying, to say the least. I then have to do a reset to gain access to the modem again.
Is that normal to lose internet functionality when I change the bridge setting?

This video says that if I turn on bridge mode that the unit only operates as a modem, and that I have to have a router also.
1. Is that correct?
2. What routers might work? Any special requirements?
3. If I turn the WiFi back on, can I leave the router in place?

Yes it's normal for the gateway to reset when putting it in bridge mode. (the router should be connected to port 1 on that device).

Just about any router will work.
You can disable bridge mode and use the router in AP mode, with the routers DHCP disabled.

FWIW, if you hang a stand-alone / separate router off of the gateway device, and the gateway is not in *bridge mode*, you are cascading 2 routing devices which results in an undesirable "double NAT" condition on your home network.
Google "double NAT" for info about its potential pitfalls.

If you want to operate with Internet Off, there is no need to go into the router's settings and change it's mode. You can simply turn off the internet connection on your PC and/or you can use the Xfinity Xfi app to Pause any/all connected devices which will stop their connection without having to reset all the settings
