i've downloaded and compiled drivers, installed driver, edited /etc/networking/interfaces
and the card on the surface appears to work, blinking lights and responds when you load or unload the driver. here is the output from my ifconfig/iwconfig

everything appears to function, even detects my local wireles access point, but on "obtaining IP address" the lights on the card stop blinking and the app doesnt connect. (i know the RA2870 is a horrible card for linux, but i've almost got it working) just not sure where to go from here
