Also noticed WIFI issues. I assumed it was related to the new addition of the RT88xx drivers from about a week ago. Have 1 Odroid-C2 using ethernet and switched a second Odroid-C2 to LibreElec from an old version of a different OS that I was keeping on it because of the 5GHz Wifi. Switched over when I noticed the new drivers in the nightlies. For me it seems I get a passphrase popup if I leave the box idle for a while. Entering the passphrase just says wrong passphrase. Only way to fix it is to unplug the Wifi adapter and plug it back in.
