Hi!
wireless is not my cup of tea... but I am willing to take a stab at it and try to assist.....
Firstly lets see if any devices are recognized. In terminal run this command and and post the output back to this thread:

Code:

lshw -C network

Depends on this result what our next step will be.

Best regards <====BDQ

I'd wait for wildmanne39 to come to this thread - he is an expert at this. He may know right away what to do, but he also has a script that gives him a lot of information when you run it and post the results back. Get a head start and follow post number 8 in this thread:

Post the requested information back in another post in this thread.

Hi, I know part of the issue but we need to see more information before I post a solution, please copy and paste this command in the terminal (ctrl+alt+t) please:

Code:

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/netscript.sh && chmod +x netscript.sh && ./netscript.sh

It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back and attach the netinfo.txt file.
Thanks
