Getting Wireless Up on Ubuntu 10.10 DELL VOSTRO 1500

After long long hours of searching and head scratching the following two-step process helped in getting the wireless up and running on Dell Vostro

Step 1: Flash BIOS

Go to the link and flash the bios according to latest.
Simply download the file and install the program and reboot.
This would enable the wlan in Ubuntu.

Step 2: Update Driver
Update the wireless driver using the following command.

$ sudo apt-get update

$ sudo apt-get install bcmwl-kernel-source

This should be done and after a reboot the Wireless should be up and running.

Immense help for this was taken from here and here.
