Chromecast cannot connect to Nighthawk M1
New installation of Chromecast (generation 3) cannot connect to Nighthawk M1 (Firmware: NTG9X50C_12.06.03.00).    QUESTION: How do I disable Access Point/AP isolation in the Nighthawk M1?    My answer...

Problem solved. :smileyhappy: And it was so much simpler than I could have imagined. After trying "just about everything" I finally did what should have been the obvious FIRST thing to do: perform a factory reset of Chromecast.
Summary: the problem lies entirely with Google Chromecast.
After configuring Chromecast to a specific Wi-Fi network, the unit is "locked" to that network. Of course this is a feature that helps when restarting Chromecast. However, when changing networks, it is a problem.
Solution: FORGET NETWORK before trying to connect to a new network. Or perform a FACTORY RESET.

Thanks for the Blanca.
I forgot to write that I've understood and changed UPnP accordingly.
My difficulty is "Disable Access Point/AP isolation", (client isolation or guest mode).
