hi there i have insalled Ubuntu 12.04 but wireless didnt work

i re installed 11.04 although the same problem plz guys help me to solve the problem thanks

..


ASAP plzzzz

[wildmanne39]

Hi, recommend reinstalling 12.04 because 11.04 is not longer supported, then 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

Can you get a temporary wired connection on the system? It'll make things easier.

[Midoo Ousman]

yes got it


thanks for ur contribution

[varunendra]

Connect to it, open a terminal and do -

sudo apt-get update
sudo apt-get install linux-headers-generic dkms bcmwl-kernel-source

Unplug the cable connection, reboot and see if the wireless works.
