No wireless connection

Deutschwings · 2015-07-07 06:37:22

Hello,
I have been using Arch Linux for a while on a temporary wired connection, but I would like to get a wireless connection working because my computer is in a really inconvenient place. According to the lspci -k command my wireless card is a Broadcom Corporation BCM4318 and I have installed the b43-firmware for it. When I try to select my network using the wifi-menu command I get this:

Job for netctl@TRENDnet.service failed because the control process exited with error code. See "systemctl status netctl@TRENDnet.service" and "journalctl -xe" for details.

The output of systemctl status netctl@TRENDnet.service is this:

● netctl@TRENDnet.service - Automatically generated profile by wifi-menu
   Loaded: loaded (/etc/systemd/system/netctl@TRENDnet.service; enabled; vendor preset: disabled)

It says that it's failed, but I have no idea on how to fix this.

Here's some more information if it's needed:

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

3 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

If I need to post anymore information just ask.

It seems strange that the wireless interface is using the traditional nomenclature but the ethernet connection is using the "predictable" naming system...

What is the output of:

cat /proc/cmdline

It looks like you may have dhcpcd@.service enabled which may conflict with netctl -- to be sure, lets see the output of:

ls -l /etc/systemd/systemd/multi-user.target.wants

With all networking .services disabled, can you connect manually?

I have the 4318 here and it's 100% reliable. I use wpa_supplicant and systemd-networkd to manage it.

I'd second Head's suggestion that you try a manual connection with no automated services running - it's the only way you will be able to see what's going wrong.

I also thought it was odd that my wireless interface was shown as wlan0 instead of something like wl2p04. When I had a fresh install using ip link would only shown me the ethernet interface and lo, but now I get the wireless interface as well, but I can't explain it, I must have added it when trying out commands to get a connection.

output of cat /proc/cmdline:

I'm going to try a manual connection, but I'm curious about how much hassle you went through to get the card working. It was my first Arch install I really have nothing important saved, and there's a good chance that I screwed up, so if it was easy for you to get the card working I might as well just reinstall.

tomk · 2015-07-07 09:31:34

No hassle at all - only difference would be that when I set it up first there was no b43-firmware package, so I did that manually using the b43-fwcutter tool, as described on the Broadcom wireless wiki page.

Not sure why you would consider reinstalling just for that, but it's your party....

Ooops, sorry...

# systemctl disable dhcpcd.service systemd-networkd.service wicd.service

Then reboot.

You should only have *one* networking .service `enable`d at a time.

If it still fails, `disable` the netctl .service as well and start again from scratch.
