Hi,

I updated to latest kernel 3.2.0-52
>> uname -a
530U3C-530U4C 3.2.0-52-generic-pae #78-Ubuntu SMP Fri Jul 26 16:43:19 UTC 2013 i686 i686 i386 GNU/Linux

but this didn't help

>> iwconfig 
lo        no wireless extensions. wlan1     IEEE 802.11abgn  ESSID:"ulla"  
          Mode:Managed  Frequency:2.437 GHz 

Doesn't work. When disabling n-mode

It works. I remind that WLAN access point is rather old clearly not
supporting n-mode.
