Public bug reported:
This is on a 2010 era Macbook Pro running a BCM4322. The b43 driver
doesn't seem to work at all. The wl driver does not work at first. The
chipset is identified, but not networks can be found. I get the
following output in dmesg:
[ 114.084059] ERROR @wl_notify_scan_status :
[ 114.084062] wlp2s0 Scan_results error (-22)
If I close the laptop lid and open it again, the wifi comes on and works
great. I submitted this bug report using the wl driver on this laptop
after closing the lid and opening.
No amount of modprobing b43 / wl in any order will bring Wifi up. The
only thing is to modprobe -r b43, and use wl, then close / open the lid.
Very weird, but annoying workaround.
Please let me know what other details I can provide. Thank you!

3 I expect the Wifi to scan networks and connect to known network after
a fresh boot using the wl driver with the b43 driver blacklisted on the
broadcom bcm4322 chipset (on a Macbook Pro 2010)
4 The Wifi does not work until the laptop is lid is closed and re-
opened.
