I have not sure this should come under Linux or ethical hacking
as this question is related backtrack 5r3. If its wrong place ..sorry for that
I am using backtrack 5r3 via Oracle Virtual Machine. Iwconfig wlan0 does not give info. Though Ping is working fine and I am able to use google thru wlan. When I checked in Network manager at backtrack..it shows my wireless connection to wired network. Apart from that command like airmon-ng is also not working.
L0 no such device
eth 0 no such device
