Wifi does not connect to chromecast
Almost 5 days trying all over
Which generation of Chromecast? Problems only with Chromecast? Did you try disabling band steering on the Fizz modem/router?
I have a first-gen Chromecast and they do not support 5 G networks. Try to connect to a 2.4G network.
You will need to download the fizz app, to adjust the settings on your router.
