Debian - Broadcom

To get firmware Broadcom Bluetooth and wifi card.

Try: 

sudo apt install broadcom-sta-common broadcom-sta-dkms broadcom-sta-source

NOTE: Needs to be KERNEL 4.19+headers.

Then reboot.

Check wifi

iwconfig

returns: 

lo        no wireless extensions.
eth0      no wireless extensions.

Check the existing PCI card

lspci -vnn | grep Network

returns: 

Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b]

Then try 

lspci -nn -d 14e4:

returns: 

Broadcom Corporation BCM4306 802.11bgn Wireless Network Adapter [14e4:4320] (rev 03)

NOTE: There are dozens of Broadcom wireless cards.

The key to finding the correct driver for any network card is what is known as the PCI ID (PCI.ID).

  • The PCI.ID in this example is 14e4:4320.
  • The revision is 03.
