Hi Marko if your WLAN interface does not show up in ifconfig or in "ls -l /sys/class/net/ " then - your system recognizes that it has to load the modules you mention when you plug in your WLAN interface - but the modules are incapable to install the interface correctly if you say you cannot bring to work ndiswrapper because its compilation fails, then you are in bad luck. I once had a similar problem with a D-Link card (featuring the adx TI-chip). What I did: I waited until a new version of ndiswrapper was available, compiled this one, and off I went. suomi On 03/27/2012 08:46 AM, Marko Vojinovic wrote: > On Tuesday, 27.
