Ubuntu – Wireless does not work (ubuntu 13.04)

broadcomnetworkingwireless

I'm new to linux and installed Ubuntu 13.04 32bit on an older Dell Inspiron E1705 laptop. Both the wireless and wired ethernet connections are not recognized. I would appreciate any help getting either working but wireless would be the most useful. The WLAN card is a Broadcom BCM4311 b/g internal card. Please help Ubuntu power users, you are my only hope!

Best Answer

Please hook up the ethernet and open a terminal and do:

sudo modprobe b44

Your ethernet should now be working. Now do:

sudo apt-get purge bcmwl-kernel-source
sudo apt-get install firmware-b43-installer

Detach the ethernet, reboot and both should now be working. If it is not yet working, please do:

sudo apt-get purge bcmwl-kernel-source

Reboot. If it is still not working, look for clues here:

rfkill list all
dmesg | grep -e b44 -e eth0

The driver b44 is correct for your ethernet device. Your system shouldn't hang loading the correct driver. Please run:

dmesg > wifi.txt
lsmod >> wifi.txt

Find the file wifi.txt in your user directory and transfer it on a USB drive or similar and paste it here: http://paste.ubuntu.com Give us the link in your reply.
