I've got the Broadcom-sta driver emerged, and I can modprobe the wl module. I can bring the wireless interface up, but when I try to use iw to scan for networks, I get no output.
/var/log/syslog returns:

Code:

May 11 13:27:28 localhost kernel: [  290.818922] ERROR @wl_notify_scan_status :
May 11 13:27:28 localhost kernel: [  290.818925] wlp2s0 Scan_results error (-22)
May 11 13:28:17 localhost kernel: [  339.354227] perf: interrupt took too long (3971 > 3950), lowering kernel.perf_event_max_sample_rate to 50100


lspci -nnk:

Code:

02:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] (rev 01)
        Subsystem: Apple Inc. AirPort Extreme [106b:008d]
        Kernel driver in use: wl
        Kernel modules: wl


rfkill list:

Code:

0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no


iwlist wlp2s0 scan:

Code:

wlp2s0    Interface doesn't support scanning.



Thanks in advance for any help, I am not sure where to go from here, but I think I'm close.
