AutoWDS can not be used in LCOS 10.30

Due to an incompatibility in LCOS version 10.30, the AutoWDS feature can not be used in a WLAN controller scenario.


The behavior manifests itself in the fact that LANCOM access points can not log on to the WLAN network configured for AutoWDS (SSID).


Currently, this behavior can only be resolved by stepping down to LCOS 10.20 RU7 on all participating devices. You can download LCOS 10.20 RU7 in our download area.
