I installed Ubuntu 12.04 and I can't seem to locate an answer on how to install the wireless drivers for it. I'm a noob linux user so, complete directions are appreciated. If you need anything to help solve the problem, you need only ask and I shall provide. Thank you, in advance, to anyone who offers any help for me.

Try this in the terminal. Ctrl+Alt+T to open up the terminal. Then type this exactly like this:

rfkill unblock all

Nothing appeared to happen and I still don't have wireless. –  user65929 May 26 '12 at 22:18
    
Used the solution from this post: askubuntu.com/questions/125624/… However, now it says disabled by hardware switch. I pressed my switch and there was no response. –  user65929 May 26 '12 at 22:25
    
And here is the solution for that little issue. I recomend listing all the devices before unblocking them. askubuntu.com/questions/139036/… –  user65929 May 26 '12 at 22:36

2.Then click Wireless and turn it on.

3.Click on the network name drop down and choose Other.

4.Give the network you want to connect. For example TP-LINK_AAB61C.

This worked for me for the Dell Inspirion 1545 with 12.04:

sudo apt-get install b43-fwcutter firmware-b43-lpphy-installer

along with opening this file to fix no sound issue:

gksudo gedit /etc/modprobe.d/alsa-base.conf

then add this to the end of the file once opened ..

options snd-hda-intel model=generic

save, close and reboot.
