The support advised me to move the controller to the 2.4ghz WiFi band in order to remove a distance cause but I am not confident since the WiFi box is not far from the controller less than 8 meters. Let’s test it!
By the way the support was not aware of such issue so the others that have the same problem, please contact Google! Thanks.
In the mean time I noticed that my nvidia shield is broadcasting direct WiFi at the same band as my router so I switched off the shield, more testing to come! I’ll keep you updated.
The wifi band doesn’t make a lot of sense since it still works in the menus.
I don’t actually have the option to switch. My router broadcasts both bands as the same name. To change that I’d have to reconnect every single wifi device in the house which is unreasonable
