The wireless card as identified by lspci:

Network controller [0280]: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02)

I'm new to Ubuntu and I've found this guide which addresses my issue exactly. I've got internet connectivity and I just want to enable the wireless card on this old Dell laptop. However, I'm running Ubuntu Server 10.10 and I would rather not install a Desktop. Thus, I'm stuck at the following step:

Step 2.

Under the desktop menu System > Administration > Hardware/Additional Drivers, the b43 drivers can be activated for use.

Is it possible to accomplish this in the CLI?

Got it to work with some help from a user in #ubuntu. Apparently there's a bug in the b43-fwcutter package that prevents the drivers from actually being loaded. Following these instructions worked for me.

As long as you have a clue about package's name you can use apt-cache to search among packages.So search for b43:

sudo apt-cache search b43

Output is:

b43-fwcutter - Utility for extracting Broadcom 43xx firmware

For me on ubuntu 10.04.So I can install it with apt-get:

sudo apt-get install b43-fwcutter

Hope it works.

  • I've done this - first step in the guide I posted above but I'm getting this with iwlist scan: wlan0 Failed to read scan data : Network is down. lsmod also seems to come up clean: pastebin.com/LkjSsm8t. I should mention that the laptop has no external wifi switches - just a Fn key combo that I've toggled every time I test something.

  • I did but I'm following the "Internet Access" portion of the guide since I've got it hooked up via ethernet.

If is no present, you need also wpasupplicant in order to have wpa and wpa2 support (see apt-cache show wpasupplicant) and set /etc/wpa_supplicant.conf

Can you show me lshw -C network?

If is ok:

1) sudo ifdown eth0

2) sudo ifup eth1 (or similar)

3) sudo ifconfig eth1 IP_static_your_machine netmask 255.255.255.0

4) sudo route add default gw adress_of_your_gateway_(like 192.168.1.0) eth0

Just download the driver from this link.

And follow the instructions here.

It works on the Ubuntu kernel version 2.6.X
