I’ve noticed on latest stable firmware after a number of days that wlan1 goes unregistered. Disabling and enabling it again registers it and clients connect again. This is repeatable.
Any ideas?
I’m seeing reports on the board with the RB4011 and wifi. Too early to tell if there is a bug in the firmware or not. Try different wifi settings, set a channel instead of Auto, don’t use DFS channels, limit the width to 40Mhz, etc.
