1 Answer

You need to install firmware-b43-installer.

If you do not have an alternative internet connection, do it this way.

If you installed bcmwl-kernel-source, then remove it.

 sudo apt-get purge bcmwl-kernel-source

1. Download these files

2. Copy them to your Ubuntu Home folder.

3. Run in terminal

   sudo dpkg -i b43-fwcutter_015-9_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

4. Reboot or run:

   sudo modprobe b43

Note: For 32-bit systems download instead of amd64 and update the file name in the dpkg command.

For Ubuntu 16.04 should be installed or the i386 alternative.

If you are having trouble finding another computer, an Android phone can be used as a USB modem. You can connect the phone and choose "USB modem" in settings.
