Hello @stevenmirabito
I have Debian Stretch with a kernel 4.14.0-0.bpo.3-rt-amd64, i can't make that work...you have a guide for Stretch?

The exit lspci of mi wireless card is:
03:00.0 Network controller [0280]: Broadcom Limited BCM43228 802.11a/b/g/n [14e4:4359]
Subsystem: Dell BCM43228 802.11a/b/g/n [1028:0014]
Kernel modules: bcma

Can you think of a way to select the latest version besides manually downloading it?
