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!
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.
