[SOLVED] Getting wifi to work with BCM4313

Hello all. I have been struggling to get wifi working on my arch setup. Unfortunately, I am using BCM4313. I have read the following post (https://bbs.archlinux.org/viewtopic.php?id=112766) but I can't seem to get this to work.
Here is some info:

$ lspci -vnn -d 14e4:
02:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)

        Flags: bus master, fast devsel, latency 0, IRQ 16
        Memory at fe500000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: bcma-pci-bridge
        Kernel modules: bcma

        Flags: bus master, fast devsel, latency 0, IRQ 32

$ sudo wifi-menu
#after selecting correct network, i get the following:
Job for netctl@wlp2s0b1\x2dMySpectrumWiFia8\x2d2G.service failed because the control process exited with error code.

 Main PID: 1193 (code=exited, status=1/FAILURE)

Initially, i wasn't even able to get wifi-menu to show me networks (it would say no valid interface). I had to blacklist b43:

$ cat /etc/modprobe.d/blacklist.conf 
install b43 /bin/false

Any ideas? Please, let me know if more info is required.
Thank you.

Re: [SOLVED] Getting wifi to work with BCM4313

Try the wl driver instead.

Are you infected with Wetiko?

Thank you for your time. I just tried using wl as you recommended.
Now I get:

$ lspci -vnn -d 14e4:
02:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)

        Memory at fe500000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: wl
        Kernel modules: bcma, wl

03:00.0 Ethernet controller [0200]: Broadcom Inc. and subsidiaries NetLink BCM57788 Gigabit Ethernet PCIe [14e4:1691] (rev 01)
        Subsystem: Dell XPS 8300 [1028:04aa]
        Flags: bus master, fast devsel, latency 0, IRQ 32
        Memory at fe400000 (64-bit, non-prefetchable) [size=64K]
        Capabilities: <access denied>
        Kernel driver in use: tg3
        Kernel modules: tg3

I didn't change anything in my blacklist.conf.

Still when I choose a network from wifi-menu I get the same output as before:

$ sudo wifi-menu
#after selecting correct network, i get the following:
Job for netctl@wlp2s0b1\x2dMySpectrumWiFia8\x2d2G.service failed because the control process exited with error code.
See "systemctl status "netctl@wlp2s0b1\\x2dMySpectrumWiFia8\\x2d2G.service"" and "journalctl -xe" for details

Re: [SOLVED] Getting wifi to work with BCM4313

My apologies OP, I didn't read your post properly.

Set the interface down before running wifi-menu and also ensure that no conflicting networking services are running.

WOW! Thank you @Head_on_a_Stick. I did as you said, 

sudo ip link set <name_of_interface> down

then proceeded to run wifi-menu. Everything works. Thanks again. Now to figure out how to automate this on boot.

EDIT: It seems there is no way to mark this post as SOLVED.

Re: [SOLVED] Getting wifi to work with BCM4313

You can mark the thread as solved by editing your first post and prepending [SOLVED] to the title.

As to automating it on boot if something is bringing the interface up disable that service and ensure the correct netctl service is enabled.
