[SOLVED] wireless connection with bcm4331

VelocityDv · 2022-01-05 07:44:03

I have installed broadcom-wl package and b43-firmware.
I have followed the tutorial on arch wiki

https://wiki.archlinux.org/title/broadcom_wireless
and have set wl on nano /etc/modules-load.d/wl.conf.

I have also followed wpa_supplicant to configure network with wpa_passphrase
https://wiki.archlinux.org/title/Wpa_supplicant

But unfortunately cannot get wireless network. however ethernet works fine.

Please post the exact wpa_supplicant command you tried along with any output in full.

Did you attempt to assign IP addresses for the wireless interface? If so then also post the relevant command(s) and any output.

Also share the output of

lspci -knn | grep -A3 'Net'

wpa_passphrase ssid passphrase

in /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/run/wpa_supplicant
ctrl_interface_group=wheel
update_config=1

network={
ssid="myssid"
psk=mypsk
}

systemctl enable dhcpcd.service
systemctl start dhcpcd.service
systemctl enable wpa_supplicant@wlp4s0.service
systemctl start wpa_suppplicant@wlp4s0.service

Head_on_a_Stick · 2022-01-05 21:10:19

If you're using wpa_supplicant@wlp4s0.service then the configuration file should be at /etc/wpa_supplicant/wpa_supplicant-wlp4s0.conf:

# /usr/lib/systemd/system/wpa_supplicant@.service
ExecStart=/usr/bin/wpa_supplicant -c/etc/wpa_supplicant/wpa_supplicant-%I.conf -i%I

The journal should confirm this as the source of the problem:

journalctl -u wpa_supplicant@wlp4s0 -u dhcpcd

And note that the service can be started at the same time as it is enabled by passing the --now flag to systemctl(1).

there is currently no file as such. would I need to create a new one and add the following? thanks

To repeat: you need a file at /etc/wpa_supplicant/wpa_supplicant-wlp4s0.conf for wpa_supplicant@wlp4s0 to work properly.

I quoted the ExecStart line in /usr/lib/systemd/system/wpa_supplicant@.service just to demonstrate this, sorry if that was unclear. The ArchWiki page you claimed to have followed also provides this information.

And please use code tags when posting terminal output. For journal content it's best to either direct the output to a file or pass the --no-pager option (--no-p for short) to avoid the clipping which is evident in your post.

VelocityDv · 2022-01-05 22:16:13

yes i have this file /etc/wpa_supplicant/wpa_supplicant-wlp4s0.conf

Okay, that looks like a Broadcom SNAFU — Linux support for that brand of wireless card is about as bad as it gets. If you have the choice *never* buy anything from that manufacturer if you want to run it with an open-source operating system. IMO the same goes for NVIDIA graphics cards but that's off-topic here.

Support for that brand is so bad the ArchWiki has a whole page devoted to it and there are two suggestions on that page for this particular card. Try them both out and if they don't work post back with full details of exactly what you tried and how you tried to implement it. Also post any relevant error messages & journal content in full. TIA.

Make sure your wpa_supplicant service isn't colliding w/ https://wiki.archlinux.org/title/Dhcpcd … supplicant
Reboot, try to connect the wifi and post the outputs of

rfkill
find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f
