Step 1: Find your dmesg(8)
, or look for your /var/run/dmesg.boot file. It will show all the hardware discovered at boot time.
Step 2: Find the device. It will either be assigned a driver (for Broadcom WiFi, it might be bwi0 or bnx0 or something else) ... or, it will say "not configured". If it says "not configured" -- this is kernel-speak for "I discovered it but there is no driver, the device is not supported".
Step 3: If it says "not configured" you cannot
use the device with the OS. Stop at this step.
Step 4: If it is assigned a driver ... read that driver's man page, such as bwi(4)
. It will describe all of the configuration options for the device.
Step 5: Read FAQ 6. Read all of it, paying close attention to section 6.13.
