I have used this adapter on my beagle bone. Are you using WPA supplicant? Is there any chance of conflict with connmand, network manager, or something else?
Another thing if u use sudo iwconfig wlan0 essid 2wire185 key
0704575771
This is for a wep encryptation key.
Probably u not have wep but wap or wpa2 key.
WEP is no longuer considered secure link..
