Follow the link Dan Ritter gave to you earlier: http://linuxwireless.sipsolutions.net/en/users/Drivers/b43/#other_distros it indicates to install (dpkg -i or apt install) b43-fwcutter and then: export FIRMWARE_INSTALL_DIR="/lib/firmware" wget http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2 tar xjf broadcom-wl-5.100.138.tar.bz2 sudo b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" broadcom-wl-5.100.138/linux/wl_apsta.o You can then set up your wireless connection Once this is done, you can install (apt install) firmware-b43-installer: this will prove useful (and automatic) if in the future this firmware is to be updated or its location changed
