I can no longer turn off WLAN 2
Since I had problems with the WLAN connection with a new device, I set up WLAN 2 on a Pirelli BBS Centro Grande ISDN router to test various settings (WPA/WEP/unencrypted/with or without visible SSID).
Since I have now been able to solve the problem, I wanted to switch off WLAN 2 (and only WLAN 2, not WLAN 1 and WLAN 2) again using the Kundencenter. When I turn it off there it is marked as turned off but it is still active on the router.
I also tried restarting the router and even tried resetting the factory settings, but the state of WLAN 2 does not change.
