My Chromecast won't connect to Wi-Fi suddenly so checked channel as I remember it has issues with higher channels but I only see channels from 149 to 165. Please see results of commands below. I have set to NZ but GUI still shows Australia & I still can't see other channels after rebooting several times.
Regardless of what channel bandwidth I choose, only see below channels.
