connecting WLAN-Stick to DHCP server


I use Angstrom /BeagleBoneBlack and try to connect the USB-WLAN stick with FritzBox. The stick is DWL-G122 RevC from D-Link (the chip is RT73) and on FritzBox a DHCP server is running. The Angstrom already is updated. Ethernet is working, but WLAN is not able to get the authentication. The BBB is powered by an external 5V/1A supply and the stick is connected by a powered USB-hub.

I know this stick is not at the wiki-list of “known working WiFi adapters”. But, do you think I can use this stick anyway and do not have to buy a new one?

My linux-know-how is limited and I hope someone can help me with more experience. This are some output information’s from BBB:

Sorry for double post. I was wondering why my post was not to see anywhere and so I send it twice. Now, one day later, I can see that my post is online now.
