Hey. I have system running on my iMac, and everything is great but the wifi. I have an 802.11 chip (BCM4321). I installed b43-firmware from the AUR, and my computer seems to accept the driver. The problem is it never finds any networks.
Here's my iwconfig:
ens5 no wireless extensions.
lo no wireless extensions.
wlan0 IEEE 802.11bg ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
Running
wifi-menu wlan0
prints
Scanning for networks... failed
No networks found
every time.
I know there should be networks here, other computers and the other OS on this computer finds them.
Any ideas?

What is the output of sudo iw wlan0 scan ??
What is the output of rfkill list ?? (You may have to install that)

iw wlan0 scan printed "command failed: Network is down (-100)"
So I turned it on with ip link set wlan0 up.
Then I ran it again, this time it printed absolutely nothing.
rfkill list:
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

Broadcom chips are pain in the ass. You may want to fiddle with drivers, there is a couple of options (brcsmac/brchmac, b43, b43-legacy, ...), check the wiki.
Also, my laptop with some shitty broadcom wlan does not show my Android's hotspot wifi in listing, no matter how hard I try. It shows other thoug so I suspect there might be frequency/channel problem there. After about half a year of troubleshooting I resigned and solved it by buying an external wifi for less than $10. As a bonus it lets me do some Aircrack magic as well
Probably not what you want to hear but that would be my suggestion.
