Hello,
When up I updated to 4.5.7 (both keeping settings and then clearing settings), my Chamberlin garage door no longer connects. It will connect to the 2.4 band w/o a password, but when using WPA2-PSK (the default) it doesn’t connect.
Reset to 4.5.6 and everything works fine. There doesn’t seem to be any firmware update on the garage door available.
