Wireless Edimax EW-7711ln Problem

[peterbro]

Just installed Ubuntu 10.10 server and all working great except the wireless interface. The card is an edimax EW-7711ln.

I installed ndiswrapper using the driver rt2860.zip found here http://ubuntuforums.org/showthread.p...-7711ln&page=4

Then I followed this guide to configure /etc/network/interfaces http://ubuntuforums.org/showthread.php?t=318539

I think the driver is loading fine but I can't connect to the access point. Here is some debugging output...

So I can scan and see the accesspoint with ssid alleycat but I can't connect. I tried disabling all security to see if it was a problem with my key or some encryption settings but even that didn't work. So frustrating because it seems close to working I must be doing something silly.

Oww and incase anyone is wondering why I am running a server off a wireless interface, its just a LAMP development server on my home network.

Any help would be greatly appreciated.

Still no luck. Is there any other commands I should post output from?
