wl driver works after shutting / opening laptop lid

[Ed Novak]

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.

I get the same behavior on a 2010 MacBookPOro7,1 with freshly installed Ubuntu 16.04.03 upgraded to 17.10.
