Problems with Broadcom Wireless BCM4312
Hello,
I have a strange behavior with my WiFi card that can't find connections.
01:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
Subsystem: Hewlett-Packard Company Device 365e
Kernel driver in use: b43-pci-bridge
Kernel modules: ssbInitially I tought that the firmware could the problem beause I was not able to find any wifi connection using 'wifi-menu'. I excluded this because of this behavior, this is the problem:
> sudo ip link set wlan0 up (works correctly)
> sudo wifi-menu wlan0
Scanning for networks... failed
No networks foundand at this point wlan0 is not up anymore.
I found a way to make it work correctly but I still want to solve this problem, the thing works if i use wifi-menu immediately after setting 'wlan0' up.
> sudo ip link set wlan0 up; sudo wifi-menu wlan0this method works like 2 times on 3.
I think it's like the WiFi adapter is being turned off automatically or something like that, any ideas?

Any chance you've more than one thing trying to control the network? You might want to post the output of systemctl --no-pager

Re: Problems with Broadcom Wireless BCM4312
Looks okay to me. My concern was that something like netctl was running.

Re: Problems with Broadcom Wireless BCM4312
I've been configuring a Dell Latitude D630 laptop this week-end. It has the same wireless card and I was having the very same problem.
Thanks for the work around. As you implied, it usually fails on the first attempt but, for me, always worked on the second.
It turns out, though, you're most of the way to getting your wireless up and working despite the way wifi-menu is acting.
If you look in /etc/netctl you should see a profile that was created by wifi-menu.
If so, then do:
sudo systemctl enable netctl-auto@wlan0.service
at the command prompt. Your wireless connection should start automatically on reboot.
Just make sure you've disabled any manual netctl profiles you might have enable previously.
Hope this works for you. It did for me.
Good luck. Thanks for helping me get off the dime.
