I have installed Ubuntu 12.04 today on my Inspiron 1545 and it works great.

I am on an ethernet connection but would like my wifi to work too.

I admit that this is my first time using any Linux distribution and I haven't got much experience with it.

When I go to my NetworkManager, he doesn't show me any Wifi connections. I already tried many codes according to other similar threads and installed a specific Broadcom driver but I still do not know how to proceed now.

It now works! I actually don't know why because I was trying different solutions simultaneously but at least it works! Thank you all for the help! –  trauftropf Mar 16 at 10:25

open the program 'software & drivers' with the dash. Now open the 'additional drivers' tab.

If there are drivers for your wireless card available, install them and see if it works.

If you have no success you can also use ndisgtk, a fronted to ndiswrapper. it is a program in witch you can load a windows driver for your wireless card and make it work under Linux. search on the CD of your laptop or online the windows driver. Now look for a .inf file in there. Open the ndisgtk program, and click install new driver. select the inf-file and click install. I am not sure but you might need to reboot.

I had already checked that, there isn't anything I can install. I also tried with the old driver DVD from Dell... –  trauftropf Mar 15 at 22:14
    
I added an other option to try, just thought of it ;). It might not be very elegant to work with windows drivers, but if it works... –  Wouter Mar 15 at 22:51
    
It is safe to run it was written by me and some good friends it will help diagnose your wireless issue. Paste this command in a terminal 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 file named (wireless-info.txt, or wireless-info.txt.tar.gz) in your home folder paste the contents of the file here pastebin.com then paste the link back here. No internet then go to this link for running the script without internet. <ubuntuforums.org/showpost.php?p=12350385>; –  Wild Man Mar 16 at 0:46
