We need to find out if your wireless card is supported. Please copy and paste this

lshw -C network

into a terminal and past the result here.

Also do this and give the outcome:

iwconfig

Also try

sudo dhclient wlan0

See if this works

sudo modprobe wl
sudo modprobe b43
sudo /etc/init.d/networking restart

Got the method from here:

http://ge.ubuntuforums.com/showpost.php?p=6040238&postcount=8

This loads the modules from the kernel which hopefully get you Broadcom card working. It then starts up the network.

See what happens if you try that.

no this was the outcome.

:~$ sudo modprobe -r b43 b44 ssb ndiswrapper bcm43xx wl
FATAL: Module bcm43xx not found.
ldrmss@ldrmss-laptop:~$ sudo modprobe wl
ldrmss@ldrmss-laptop:~$ sudo modprobe b44
ldrmss@ldrmss-laptop:~$ sudo /etc/init.d/networking restart
* Reconfiguring network interfaces... ok

but nothing happens.

this is my laptop if that helps.

thanks for the help

An Fear Aniar · 05-11-2008 10:53PM

OK, I assume you didn't install ndiswrapper and all that?

It's just these commands here:

sudo modprobe -r ssb
sudo modprobe wl
sudo modprobe b43
sudo /etc/init.d/networking restart

ldr · 05-11-2008 10:58PM

i did and this was the result

ldrmss@ldrmss-laptop:~$ sudo modprobe -r ssb
FATAL: Module ssb is in use.
ldrmss@ldrmss-laptop:~$ sudo modprobe wl
ldrmss@ldrmss-laptop:~$ sudo modprobe b43
ldrmss@ldrmss-laptop:~$ sudo /etc/init.d/networking restart
* Reconfiguring network interfaces... [ OK ]
ldrmss@ldrmss-laptop:~$

but still nothing. cant detect any wireless network

ldrmss@ldrmss-laptop:~$ lspci | grep Broadcom\ Corporation

An Fear Aniar · 05-11-2008 11:43PM

Sorry, try this:

sudo rmmod ssb
sudo modprobe wl
sudo modprobe b43
sudo /etc/init.d/networking restart

If that doesn't work, go to the Ubuntu forums:

finally got it to work.
but i dont think the driver is well installed because i get this message

fwcutter is a tool which can extract firmware from various source files.It's written for BCM43xx driver files.

plus im right next to the modem and im not 100%.

any suggestions?

one more thing is possible to update the drivers? and do i do it?

thank you very much for your help

An Fear Aniar · 06-11-2008 10:04PM

Glad you got it working, I would advise you to post on this thread in the Ubuntu Forums

http://ubuntuforums.org/showthread.php?t=963978

It's a thread dedicated to Broadcom wireless in 8.10

Does your driver show up in System/Administration/Hardware Drivers ?
