After you connect to internet using your smartphone and USB cable, do this
sudo apt install bcmwl-kernel-source
More details here https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx
Based on the source, it looks like you might try the b43 driver. https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx
Specifically, this post suggests following commands:
Remove bcmwl-kernel-source package, then reboot.
sudo apt-get remove --purge bcmwl-kernel-source sudo reboot
Install b43 broadcom firmware.
sudo apt-get install firmware-b43-installer
sudo modprobe -r b43 sudo modprobe b43
I finally make it work,
uninstall all drivers for a fresh install
sudo apt-get purge b43-fwcutter firmware-b43-installer firmware-b43-lpphy-installer firmware-b43legacy-installer bcmwl*
re install only this ones
sudo apt-get install firmware-b43-installer b43-fwcutter
after that remove or comment the blacklisted kernel module
bcm43xx in the file /etc/modprobe.d/blacklist.conf. You can do it manually or with this command
keyword='blacklist bcm43xx'; sudo sed -i "/^$keyword/ c#$keyword" blacklist.conf
