I just installed Lubuntu on Dell 1300. But I can't connect to Internet on this laptop and so I can't install all updates and drivers. I didn't find any information about my problem for Ethernet connection and I don't know how to solve this problem. Can you help me?

Output of lspci -knn | grep -EA2 'Eth|Net'

  • @Pilot6 done it Aug 29 '15 at 17:41
  • Which version of Lubuntu did you install? 64 or 32-bit?

  • @Pilot6 32-bit, because laptop has less than 1Gb of memory. Aug 29 '15 at 17:52
  • I gave a solution for both.

For a 64-bit system:

Download these files to your home folder:

http://mirrors.kernel.org/ubuntu/pool/main/b/b43-fwcutter/b43-fwcutter_018-2_amd64.deb http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2

Then run in terminal:

sudo dpkg -i b43-fwcutter_018-2_amd64.deb
tar xfvj broadcom-wl-5.100.138.tar.bz2
sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.100.138/linux/wl_apsta.o

For 32-bit:

http://mirrors.kernel.org/ubuntu/pool/main/b/b43-fwcutter/b43-fwcutter_018-2_i386.deb http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2

sudo dpkg -i b43-fwcutter_018-2_i386.deb
tar xfvj broadcom-wl-5.100.138.tar.bz2
sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.100.138/linux/wl_apsta.o

You can download the files using another computer.

The Ethernet should be fixed by

sudo apt-get purge bcmwl-kernel-source
