(tested with 2 different chromecast ultra)
The 2.4G network is detected ok, but 5G is not detected by the Chromecast
But I have managed to make it work with a little trick:
- Disable 5G network
- Change the name of the 2.4G network to be the same as the 5G network
- Configure Chromecast Ultra using that 2.4G network
- Change back 2.4G network name to the original and activate 5G
- Now Chromecast connect to the 5G network!
This happens with firmware 3.027 and also 3.104 (current testing)
Any idea what could be happening?
