Hi,

The sudo iwlist scanning output indicates that your wireless card is able to find active wireless networks.

You should have the NetworkManager icon in the top right corner of the Ubuntu desktop.

The following link shows a screen of NetworkManager:

http://en.wikipedia.org/wiki/Networkmanager

Right click on the NetworkManager and select your wireless network in there. You might need to edit connections, then choose the eth1 wireless adapter and then select the wireless network.

Please let us know how it goes.

If you cannot see the NetworkManager in the top right corner, you can open a Terminal and enter the following command to manually start it:

nm-applet

Regards,

Mark

The problem is it will not connect to any networks and does not pull up any networks to connect to. I run the utility as it says to, but it does not connect. I finally decided to return the machine because now half the applications no longer open on it and i have only had this machine for two days. Thanks you for you help on this. I am returning it because the company that sold it to me will not help me with the problems. I am going back to XP as I do not speak DOS, LoL.

Thanks

Jennifer

Thanks Mark Rijckenberg, that solved my question.

Hi,

In case someone else has issues with the same wireless chipset (BCM4312 802.11b/g [14e4:4315] (rev 01) ), then I advise following this installation procedure:

Boot your laptop and enter BIOS setup utility: choose option "load default values".

Insert the Ubuntu 8.10 LiveCD. Boot from this CD and install Ubuntu 8.10 onto your harddisk using the LiveCD session.

After installation, reboot into the installed Ubuntu 8.10 system.

Download the following drivers:

http://www.broadcom.com/docs/linux_sta/hybrid-portsrc-x86_32-v5_10_27_14.tar.gz

which come from this site:

http://www.broadcom.com/support/802.11/linux_sta.php

Follow these build and installation instructions carefully:

http://www.broadcom.com/docs/linux_sta/README.txt

In a terminal, type : sudo gedit /etc/modules

Add the following line to the end of the modules file

wl

sudo gedit /etc/modprobe.d/blacklist

Add the following lines to the end of the blacklist file

blacklist b43
blacklist bcm43xx
blacklist b43legacy
blacklist ndiswrapper

Reboot and then test wireless.

Regards,

Mark
