Hi,

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Run the following command. The command STARTS with the word sudo and ENDS with the word restart. So please copy-paste the ENTIRE command below into a Terminal, press enter, then enter password when sudo asks for password, then press enter again.

sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; uname -a; dmesg | grep ound; dmesg | grep b43; iwconfig; sudo /etc/init.d/networking restart

Step 3: Please post results (copy/paste terminal output) on this thread

Step 4: Please also specify the exact model and make of your PC (if known) on this thread

Regards,

Mark

Hello,

The following works every time for me with my Broadcom card and running Ubuntu 9.04....

extract the b43-fwcutter tarball and build it:
wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-011.tar.bz2
tar xjf b43-fwcutter-011.tar.bz2
cd b43-fwcutter-011
make
cd ..
Use version 4.80.53.0 of Broadcom's proprietary driver.
Download and extract the firmware from this driver tarball:
export FIRMWARE_INSTALL_DIR="/lib/firmware"
wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
tar xjf broadcom-wl-4.80.53.0.tar.bz2
cd broadcom-wl-4.80.53.0/kmod
sudo ../../b43-fwcutter-011/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta.o

Note that you must adjust the FIRMWARE_INSTALL_DIR path to your distribution. The standard place where firmware is installed to is /lib/firmware. However some distributions put firmware in a different place.

Good luck!!

My instructions from step 2 were not followed correctly. Please send output of following command:

sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; uname -a; dmesg | grep ound; dmesg | grep b43; iwconfig; sudo /etc/init.d/networking restart

The commands STARTS with sudo and ENDS with restart

Mark,

Thanks for the advice. I am traveling and will get back to the problem
this weekend. I hope you are still available to give me advice by
then.

Thanks again

When you get back, look in System-->Administration-->Hardware Drivers if anything with Broadcom is listed.
