I'm on an archlinux 4.4.1-2 and I'm trying to set up a netctl service. Problem is that for netctl to work I need to have bcma and b43 loaded. Since these two are not out-of-tree modules I thought I didn't had to load them myself.

Neverthless I also tried to load described in this article here. Unfortunalty this doesn't seem to work either. Has anyone an Idea what the problem could be? thanks:D

  • Can you go into a bit more detail on how it didn't work? What did you see, what did you expect to see? – Wouter Verhelst Feb 21 '16 at 21:16
  • I am expecting to have bcma and b43 in lsmod after boot. But i have to modprobe them myself. So actually without these two modules my wireless card isn't detected and my wlan0 interface is missing – bmblby Feb 22 '16 at 22:11

There is a file /etc/modules which lists modules to be loaded at boot. Just add those modules to that file

    Thank you this helped me a little. Because I am on Arch Linux there is no modules file in /etc/, but there is another location where modules are configurated on arch. It is in /usr/lib/ and exactly there, my modules where blacklisted. So I removed a file in /usr/lib/modprobe.d that blacklisted the modules and know it works. – bmblby Mar 19 '16 at 10:04
