[arch-general] wireless driver broadcom b43 random success or failure
Readers, Can anyone explain if the following 'dmesg' outputs are useful to understand why after start of X session, the wireless driver fails sometimes? The wireless driver does not start automatically and is always started manually with the command (as root): modprobe b43 Below is the dmesg output when the command above, starts successfully the wireless driver: b44: Broadcom 44xx/47xx 10/100 PCI ethernet driver version 2.0 b44 ssb1:0 eth0: Broadcom 44xx/47xx 10/100 PCI ethernet driver ... IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready b43-phy0: Broadcom 4311 WLAN found (core revision 10) b43-phy0: Found PHY: Analog 4, Type 2 (G), Revision 8 b43-phy0: Found Radio: Manuf 0x17F, ID 0x2050, Revision 2, Version 0 Broadcom 43xx driver loaded [ Features: PNLS ] ieee80211 phy0: Selected rate control algorithm 'minstrel_ht' IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready b43-phy0: Loading firmware version 666.2 (2011-02-23 01:15:07) IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready wlan0: authenticate with ... wlan0: send auth to ...

Thanks. Created a 'conf' file (root user): cat > /etc/modprobe.d/b43.conf modprobe b43 Then restarted computer. The module failed to load. On attempting the usual command, a new error occurred: modprobe b43 libkmod: kmod_config_parse: /etc/modprobe.d/b43.conf line 1: ignoring bad line starting with 'modprobe' So, deleted the 'b43.conf' file and loaded the module manually again.
I think Mauto means, use /etc/module-load.d and make new conf?

You should re-read the wiki section I pointed you to. That is not the syntax of the configuration files for modules-load.d. Also arch does not use /etc/modprobe.d, if you are not using Arch Linux you are on your own. -- Mauro Santos

Little nit-picking: the `modprobe` command is available (and used) on Arch Linux, and it *does* use the files in /etc/modprobe.d (see also modprobe.d(5) for what the files are used for). So this is not really an indication for whether OP's using Arch or not. However, yes, automatic module-loading at startup is not modprobe's job, so it's the wrong location to configure such stuff. Please have a look at modules-load.d(5) instead (and take a second, more precise look at the wiki article Mauro posted).

That is correct, my bad on that one. I was thinking only about module loading at boot time. -- Mauro Santos
