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! 1 Description: Ubuntu 16.04.3 LTS Release: 16.04 (fully updated) 2 $ apt-cache policy bcmwl-kernel-source bcmwl-kernel-source: Installed: 6.30.223.271+bdcom-0ubuntu1~1.1 Candidate: 6.30.223.271+bdcom-0ubuntu1~1.1 Version table: *** 6.30.223.271+bdcom-0ubuntu1~1.1 500 500 http://us.archive.ubuntu.com/ubuntu xenial-updates/restricted amd64 Packages 100 /var/lib/dpkg/status 6.30.223.248+bdcom-0ubuntu8 500 500 http://us.archive.ubuntu.com/ubuntu xenial/restricted amd64 Packages 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.
