FW VERSION RUT9_R_00.07.00
I have setup an access point and a client wireless interface on my RUT955. The problem is that when the client connection goes offline, the access point also disappears.
I added the client wireless using the scan button so would expect this to work out of the box.
Any help would be much appreciated.
I couldn't reproduce your issue. Client wifi configuration stays there when connection goes ofline or even router restarts.
For testing purposes I would advice to reset router to factory settings and check if it solves the issue. Before that please make a configuration backup to not lose your previous system settings.
