how to install wireless driver for Dell 630 in Ubuntu

It's the first time that I tried the Ubuntu. But I met quite a lot of problems. The wireless is just one of them. But thanks for the internet, I got a lot of help from a lot of guys. Here I would like to list the steps that help install the wireless dirver in D630.

I mainly got the help from below two pages.

The reason why I listed two pages here is because one of the page doesn't list about how to install the b43-fwcutter. That's also why I composed this article here: combine the information from two pages together and show the final instructions.

1. check your wireless card type by typing below command: lspci -vnn | grep 14e4. Make sure that your wireless card is one of Broadcom43xx. (you will see the message from the terminal once the card is one of Broadcom43xx.

@ubuntu:~$ lspci -vnn | grep 14e4
09:00.0 Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM5755M Gigabit Ethernet PCI Express [14e4:1673] (rev 02)
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)

2. Install b43-fwcutter by running below command: sudo apt-get install b43-fwcutter

3. Download the driver from http://downloads.openwrt.org/sources/, file name as broadcom-wl-4.80.53.0.tar.bz2. It will be downloaded in /home/Downloads

4. Unzip the file by tar jxvf broadcom-wl-4.80.53.0.tar.bz2

5. Go into the kmod foler : /broadcom-wl-4.80.53.0/kmod/

6. Install the driver: sudo b43-fwcutter -w /lib/firmware wl_apsta.o

That's it!
