Comment:

 I tested with recent SHR testing and latest andy-tracking
 (4c9a8d5badc466a68d71754d47bbb792a8dc44da).

 I killed wpa_supplicant and avahi then turned on WIFI using the GUI.
 I'm sure I was not using usb0 also.

 First, with open network.

 iwconfig eth0 essid LINUX

 I set up an IP manually, gateway, etc and it worked.

 I also used WEP. The key is not my real key.

 iwconfig eth0 key 00005D0005 essid LINUX

 udhcpc worked.

 One thing to point out is that it did not work for me when I was far.

 It worked when I was about 2 meters form the AP with better S/N ratio (I
 didn't test with intermediate points and I don't think it is relevant).
