Troubleshooting the ipw2200 Card for WVU Wireless.

This is a more indepth extension to the ipw2200 wireless card problem Craig
had mentioned in the tutorial.

Errors with ipw2200 firmware upgrade:

According to the ipw2200 firmware upgrade there is a possibility of errors
with removal of old ieee80211 modules.  So you will have to manually remove
them.  Even deleting the old directories may be the best solution and that's
what worked for me.  Then you can properly compile.

1)  Authenticate with wpa supplicant.
2)  dhclient <interface>
     -you might get a problem resembling this...

So Here is the Resolve<http://ubuntuforums.org/archive/index.php/t-78983.html>
:

sudo gedit /etc/modprobe.d/ipw2200
(you probably will have an empty file or no file)

regardless, add this line:
options ipw2200 hwcrypto=0
save
then run: sudo modprobe -r ipw2200
and then: sudo modprobe ipw2200 hwcrypto=0

Try to dhclient again and see if it will bind with an IP.
