I have a Pi Zero W, with Rasbian (full) (2017 02 16), and I've had it connect on Channel 13 to the local network, and have been SSHing to it.
Just tried LibreElec 188.8.131.52, and it didn't appear to identify my access point. I changed to Channel 11, following this thread, and it finally showed. But it could be a signal strength issue. I can't connect to it due to some glitch. Notification flashes: 'network error operation aborted'. I've WIFI issues with another computer running OpenElec, so not sure if this is related or not. I have an old access point.
I tried to stream video to LibreElec using it as an access point, but it didn't really work out for me. I'm starting to suspect I need more power, or an alternative/better power supply. Or I'm expecting too much from the Pi0.
The thing to note is that Rasbian, with credentials added via wpa_passphrase, has worked (with SSH at least).
