Can't find my wireless device

Good evening,

just got Arch up'n running with xfce4 and various window managers.
Wired network works fine. Wireless, not so good.

hwdetect --show-net gives me:

$ hwdetect --show-net
NET    : tg3 ieee80211 ieee80211_crypt mac80211 ipw3945 iwl3945 cfg80211

I can find ipw3945 in the lists of modules in rc.conf, but I can't find anything called wlan0. Just eth0 and lo.

What's the problem?

Re: Can't find my wireless device

Have you installed the package iwlwifi-3945-ucode?

Oh... also check if there is any conflict between iwl3945 and ipw3945 (old driver).

Re: Can't find my wireless device

pacman gave me:

pacman -Qs 3945
local/ipw3945 1.2.2-10
    Driver for the Intel PRO/Wireless 3945ABG miniPCI express adapter
local/ipw3945-ucode 1.14.2-2
    Intel Centrino Drivers firmware for IPW3945
local/ipw3945d 1.7.22-4
    Regulatory daemon for IPW3945
local/iwlwifi-3945-ucode 2.14.1.5-2
    Intel wireless firmware for IPW3945 (iwlwifi driver)

Should I remove the two first entries?

Re: Can't find my wireless device

Use only one of iwl3945 or ipw3945.  They will conflict with each other.
ipw3945 is the old driver.  It uses device name ethX.  It requires a regulatory daemon name ipw3945d, and firmware named ipw3945-ucode.
iwl3945 is the newer driver.  It uses device name wlan0.  It has no regulatory daemon, and uses firmware iwl3945-ucode.

I suggest trying iwl3945 first.  Remove all your ipw- packages (the first 3 in the list you provided).

I removed the files, but it still doesn't work.

Re: Can't find my wireless device

ipw3945.ucode load failed: Reason -2
it still search for ipw3945...
I imagine you are using the latest kernel so try this:
rmmod ipw3945
modprobe iwl3945
add iw3945 to your /etc/rc.conf modules=() line
remove from that line the ipw3945
install if you don't have it the "wireless_tools" package
run in a console iwconfig and tell us the output
(try to reboot too to see if the driver is correctly loaded after the first reboot)
tell us how it's gone and good luck

I take it that you meant I should add "iwl3945" to the modules and not "iw3945", Marco.

Re: Can't find my wireless device

Apparently, you did not remove ipw3945.  Try this:

pacman -R ipw3945
rmmod iwl3945
modprobe iwl3945

If all went well, you can try to bring up your interface

ifconfig wlan0 up

The rest is in the wiki: http://wiki.archlinux.org/index.php/Netcfg
Good luck.

Re: Can't find my wireless device

I did remove it. And forgot to mention, iwconfig tells me there are no wireless devices.

Re: Can't find my wireless device

Well, that's weird.  ipw3945 shouldn't load if it was removed...
Did you reboot after removing it?

Another thing you can do is add !ipw3945 to your MODULES array and reboot.  If it still loads after that, then your machine is possessed!

Re: Can't find my wireless device

Jun  6 04:14:11 archblue ipw3945: ipw3945.ucode load failed: Reason -2
Jun  6 04:14:11 archblue ipw3945: Could not read microcode: -2

this is the only relevant error..
have you tried my suggestion?
("rmmod ipw3945","modprobe iwl3945","iwconfig")

edit:
(following the suggestion of peart it is better this:
("rmmod ipw3945", "rmmod iwl3945", "modprobe iwl3945", "iwconfig")
so if the iwl3945 module is loaded but doesn't work well, this reload it too..

Re: Can't find my wireless device

Well, that's weird.  ipw3945 shouldn't load if it was removed...

Unless he still has it inside the initrd. He should update it.

Re: Can't find my wireless device

Marco, I tried
"rmmod ipw3945"
"rmmod iwl3945" and
"modprobe iwl 3945"

And it works!

I've found out that I first have to "rmmod iwl3945" before I "modprobe iwl3945" in order for it to work. However, I have to do this every time I boot my computer.
How do I automate this task?

And I still get errors: errors.log

Re: Can't find my wireless device

are you sure that (even after the rmmod ipw3945) on reboot it still searching for ipw3945 firmware?
I don't know if carlocci is right, but I never known of wireless driver in initrd.
I know the ugly way to get it working on every reboot
(putting the line I suggested you in /etc/rc.local) but not the good way...
let's wait for some better solution

edit:
I write the "/etc/rc.local" that should TEMPORARILY fix your problem (this is the ugly way) just to be more clear..

#!/bin/bash
rmmod ipw3945
rmmod iwl3945
modprobe iwl3945

I hope this help

Re: Can't find my wireless device

It seems like I've got the same problem here. rmmod followed by modprobe does appear to fix the problem, but it would be nice if there were some other solution

In my case, I didn't have to worry about removing the ipw firmware.

less /var/log/dmesg.log | grep 3945 looks like this:

iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 1.2.23k
iwl3945: Copyright(c) 2003-2007 Intel Corporation

iwl3945: Failed to register network device (error -12)
iwl3945: probe of 0000:05:00.0 failed with error -12

Needless to say, I'm using the wired ethernet port at the moment

Re: Can't find my wireless device

Thanks for the script Marco.

Actually, the wireless isn't the only problem I have with Arch. It seems that Arch doesn't save the changes I'm making to my system. I'm fond of mpd + Sonata. And every time after a reboot I have to

chown username:users /var/lib/mpd/*
touch /var/run/mpd/mpd.pid
chown username:users /var/run/mpd/*
chown username:users /var/log/mpd/*
mpd

I also got my Wacom tablet up and running, but after a reboot it didn't work anymore.

I made a script for the mpd-startup which saves me some time. But I'd still want to fix the problem.

Maybe I should start a new thread based on the discovery of the extent of my problems?

Cheers,

Daniel.

Oh, and Harry, wireless works fine! As long as you rmmod and modprobe

Re: Can't find my wireless device

Yep, I've done that, and it works. Like you, though, I still want to know what the problem is
