I'm trying to connect my two Chromecast Ultra devices to my ZyXEL AX7501-B0 WiFi router. It just doesn't connect… 😣
I did factory resets of the Chromecasts and also the ZyXEL WiFi router. After that, I started the Google Home app on my Android phones (tried multiple; lets say it's a OnePlus 7). It finds the devices and suggests to do a setup. I see these 4 digits/chars on the screen and confirm that I also see them on the app and then I try to connect it to the WiFi.
It fails. After a period of time, it shows that the connection is not possible.
The Chromecasts are also connected with LAN cable. Does not help.
The WiFi itself works just fine; other devices can connect and Internet connection is possible.
It never used to work with this WiFi; before that, I was using an AVM Fritz!Box.
