I managed to get it working, but only temporarily. The drivers were installed inside of
The device is indeed recognized by iw and ip link 9. So there must be a problem with how it is interfacing with these other linux services that handle network devices. I am not an expert in Linux so I don't know where to go to correct the problem.
Now, upon using wifi-menu, I am returned with the following error output:
b43-phy2 ERROR: Microcode not responding. Could not set interface wlan0 flags (UP) : No such device nl80211: could not set interface wlan0 UP WEXT: Could not set interface wlan0 UP wlan0: failed to initialize driver interface failed
ip link shows the device is there (and is indeed DOWN), and systemctl shows the bcm4311 modules are loaded and running. I tried ip link wlan0 up and got an identical message. I tried deleting and reinstalling the b43 folder with
b43-fwcutter broadcom-wl-5.100.138/linux/wl_apsta.oand running
ip link set wlan0 up. Same result.
