I have BT5 installed on my computer with a duel boot on a hdd seperate from my windows install. I am using the Alfa AWUS036H and have it configured. I was able to run airmon-ng, ifconfig, airodump etc... i was able to collect the packets on my network and get my wep key, however when i went to connect with Wicd i get nothing. iwconfig shows:
 wlan1 IEEE 802.11bg ESSID:off/any 
mode:managed Access Point: Not-Associated Tx-Power=0 dBm 
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key: off
Power Management:off
(sorry I am posting on my laptop in windows since i cant connect with my desktop on BT)
airmon-ng shows
wlan1 Realtek RTL8187L (chipset) rtl8187 - [phy17] (driver)
The Wicd preferences are set with wlan1 for the wireless interface DHCP client automatic Route Table Flushing Automatic WPA supplicant driver: wext Backend: external
I have been surfing the BT forum, ubuntu forum and the BT wiki, trying different things, none of which have worked. I know my card is working cause I can pick up all the nearby networks on airodump
