Before Linux Kernel 3.0 (2.6.39) I can run the following command:
# ifconfig wlan0 up
Now I can't. I got an error saying that this device was not found. I've tried to unplug my usb dongle, plug and check how it is registered but i don't get any useful output.
What should I do when dmesg dont help? How could I identify how my device was registered?
Thank you.
