[SOLVED] b43 wifi fail to load on startup

Dear all, I'm a reasonably new Arch user, and am taking to a liking to the distro . Hopefully I'm posting this in the right section!

Since today (after a full update) my wifi driver (b43) fails to load at boot. The weird thing is that doing "sudo modprobe b43" loads it and it works no problem.

What I already did:
/modules-load.d/b43.conf

#!/bin/bash
b43

grep -R b43 /modprobe.d/
empty

grep -r 'blacklist' /etc/*
empty

Made startup bash file
/etc/rc.load

#!/bin/bash
modprobe b43

journalctl | grep 'b43'

So even though there is (at least I did not find) any file specifically containing a blacklist, the module IS blacklisted. Is there another place I could find such a blacklist?

Re: [SOLVED] b43 wifi fail to load on startup

Can we see the output of:

cat /proc/cmdline
grep -R b43 /etc/modprobe.d

Also, you should post the actual commands and configuration files that you tried rather than a vague description.

Re: [SOLVED] b43 wifi fail to load on startup

Thanks a lot for the quick message! I'll update OP for completion.

cat /proc/cmdline:

BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=45d42f4d-419f-4472-b15d-d54b4534d74a rw quiet

grep -R b43 /etc/modprobe.d

empty

Re: [SOLVED] b43 wifi fail to load on startup

Oh dear, we should have checked the ArchWiki first...

https://wiki.archlinux.org/index.php/Ke … o_not_load

Does that help?

blacklist was in:
/usr/lib/modprobe.d/broadcom-wl.conf

The module no longer is blacklisted, feel kind of ashamed right now :X.

EDIT:

I should think before I post, everything is fixed now!

(The error I was having after removing the blacklist was my own fault, my b43.conf was written wrong)

#!/bin/bash
modprobe b43

isntead of

#!/bin/bash
b43
