Latest update breaks WLAN

Hi, I updated OSMC and lost the ability to connect my Asus Wifi. The connection icon shows a successful connect (green tick mark) but DHCP fails to configure properly. DHCP via wired network works fine. Just recently I installed OSMC 20150830 from image. Day before yesterday I installed an update. Any idea how to reestablish WLAN?

We need some logs so we can determine what the problem is.
