I have a USB wireless adapter D-Link DWA-131. I also have backtrack 5R1 on Vmware. I installed the driver on the system, and here are some outputs:
root@bt:~# lsusb Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 002: ID 07d1:3303 D-Link System DWA-131 802.11n Wireless N Nano Adapter(rev.A1) [Realtek RTL8192SU] Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub root@bt:~# iwconfig lo no wireless extensions. eth1 no wireless extensions. eth2 no wireless extensions. wlan0 unassociated Nickname:"rtl_wifi" Mode:Auto Access Point: Not-Associated Sensitivity:0/0 Retryff RTS thrff Fragment thrff Encryption keyff Power Managementff Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Please note that the chip of the adapter is RTL8192SU, and it's installed successfully on the system.
The problem comes when I can't use the wireless adapter to scan available networks.

How can I get this adapter to work?
