After the OTA update to iOS 6 my new iPad fails to connect to my WiFi network at home. My LANCOM router reports the following issue:

 

Index: 62294

Zeit: 19.09.2012 21:08:28

Interface: WLAN-1

Ereignis: Rejected Association from WLAN station xx:xx:xx:xx:xx:xx []: ()

Adresse: xxxxxxxxxxxx

Grund: Cannot support all requested capabilities in Capability Information field

 

It has worked flawlessly in the past with iOS 5 on my new iPad and iPhone 4. At the moment I hestitate to update my iPhone too.

 

Anyone with the same issue or an idea how to fix it?

 

Thanks in advance, greetings from Stuttgart (Germany),

Jens

I did contact the LANCOM regarding the issue and they traced it down to the 802.11r support in iOS, which must have been introduced with iOS 6.  Support for 802.11r is indicated by a new capability bit (Bit 12: Radio Measurements) in the association requests that was previously reserved.

 

Their old firmware simply rejected any association requests which had this bit set (e.g. iPad 3 with iOS 6). Luckily I got a patch from them, so that my LANCOM 1821 now ignores this capability bit:

iPad mit iOS 6 kommt nicht mehr ins LANCOM 1821 WLAN (German)
