Wifi doesn't work on Dell laptop
Hi, I can't get the wifi to work (doesn't pick up with wifi signal) although it says that it is activated and currently in use: Broadcom STA wireless driver. I have a Dell Latitude D520. I have followed the instructions for testing and include here the Terminal output. Thanks, Dougal
