I have a Dell Inspiron 1520 with the Dell Wireless 1390 WLAN Mini-Card, one that has given many Linux users big headaches.

After trying many different approaches suggested all over the web, and gathering clues in many Ubuntu forum posts, I finally worked out this solution:

First of all you must check if you have the correct card:

lspci -nn | grep 14e4

Result: 05:00.0 Network controller [0280]: Broadcom Corporation BCM94311MCG wlan mini-PCI [14e4:4311 (rev 01)]

Then proceed to the first step:

1. blacklist bcm43xx

echo blacklist bcm43xx | sudo tee -a /etc/modprobe.d/blacklist

2. install ndiswrapper and related files

sudo apt-get install ndiswrapper-common ndiswrapper-utils-1.9 ndisgtk
