The title pretty much says it.

All the useful information:

I know the wireless itself is working because I could get it working with windows.
I appreciate any help.

Hi, copy and paste this command in the terminal (ctrl+alt+t) please:

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

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, click on the paper clip and attach the netinfo.txt file.
Thanks

Thank you for the fast reply, Wild man.

[wildmanne39]

Hi, you are missing the firmware.
Please do:

sudo apt-get install --reinstall linux-headers-$(uname -r) build-essential

Then:

sudo apt-get install linux-firmware-nonfree

sudo modprobe b43

Thanks

[leon.alberti]

Thank you, it's working (altough it's giving erros messages when connecting).
Marking as solved.

[wildmanne39]

What error messages? from where?
Thanks

[leon.alberti]

Strangely it only appeared the first time I connected, it was something related to user privilege.
Anyway, it's working perfect now. Danke!

[wildmanne39]

Your welcome!
