Arch seems to think that my wlan0 isn't a wireless interface anymore

"!#% Two days ago, I got my wireless up an running just fine. Then I had to reinstall, and now, even though I believe I have done EXACTLY the same as before to my rc.conf and wireless script, netcfg2 just gives me this nice message:

[root@archcomputer reploid]# netcfg2 wireless_home
:: wireless_home up  - Interface wlan0 is not a wireless interface       [FAIL] 
[root@archcomputer reploid]# netcfg2 ethernet_home
:: ethernet_home up                                                      [DONE] 
[root@archcomputer reploid]#

Modules should be autoloaded, you can see my iwl3945 in there;

MOD_AUTOLOAD="yes"
#MOD_BLACKLIST=() #deprecated
MODULES=(tg3 iwl3945 snd-mixer-oss snd-pcm-oss snd-hwdep snd-page-alloc snd-pcm snd-timer snd snd-hda-intel soundcore)

I even put wlan0 in together with INTERFACES, although I believe I should be able to uncomment that as well?

#eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
#eth0="dhcp"
#wlan0="dhcp"
INTERFACES=(eth0, wlan0)

And network-profiles is in my daemons list

DAEMONS=(syslog-ng network netfs network-profiles crond hal fam alsa)

Still, ifconfig doesn't return an entry for my wlan0

iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

The only thing I can think of that I have done differently, was installing gnome-network-manager, but I didn't get that working, either, so I just pacman -R ed the whole thing.

the intel iwl-drivers are still installed though.

Any clue where I should look for errors/what has gone wrong?

Re: Arch seems to think that my wlan0 isn't a wireless interface anymore

Re: Arch seems to think that my wlan0 isn't a wireless interface anymore

It seems that my lsmod is slightly different, and that ipw3945 has gotten into the list now, it wasn't there on my previous install. Hmm..

Old lsmod: http://pastebin.com/me8548a4

New, troubled one: http://pastebin.com/m45a1f7d8

Anybody have a clue whether this could be the cause of the problem?

to czar:
[root@archcomputer reploid]# ifconfig wlan0 up
wlan0: unknown interface: No such device
[root@archcomputer reploid]#

What is that and how do I install that?

I checked every box on my Arch install.

Device shows up on lspci: 03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)

However not on iwconfig or:
ls /sys/class/net
eth0  lo

No wireless interface there

Re: Arch seems to think that my wlan0 isn't a wireless interface anymore

I DO have the firmware installed, both tried to download again, and pacman -Qi for iwlwifi-3945-ucode. It appears to be installed.

I tried to remove (pacman -R) all other packages containing 3945, but ipw3945 still shows up in lsmod, after reboot. And I can't get online with the wifi.

There is something fishy going on here.

Re: Arch seems to think that my wlan0 isn't a wireless interface anymore

It doesn't work.

I have put ipw3945 on the blacklist, along with
#
ieee80211              30664  1 ipw3945
#
ieee80211_crypt         4992  1 ieee80211

that weren't in my old lsmod. Still, to no avail. No f!"#¤ing clue.

*sigh...
reinstall again

Re: Arch seems to think that my wlan0 isn't a wireless interface anymore

errf just noticed... try removing NETWORK from your daemons array, comment out INTERFACES in rc.conf and add NETWORKS with your netcfg2 profiles if you didn't already.

Re: Arch seems to think that my wlan0 isn't a wireless interface anymore

Yay! The last thread "solved" the problem. I am saying "solved," because modprobe -r modprobe on startup every time doesn't really diagnose the problem, it offers a rather tedious solution that has to be done manually everytime.

Very strange. I thought I just had a n00b problem, but then it turned out to be a real riddle.

Anyway, thanks for taking your time and showing perseverance, Bankok. I know that was a real hassle, I appreciate it.

Re: Arch seems to think that my wlan0 isn't a wireless interface anymore

instead of typing it everytime just add it into rc.local or another startup script (idk where the proper place would be)

Re: Arch seems to think that my wlan0 isn't a wireless interface anymore

As for me...
I think that Reploid have just to recompile firmware for his card.
Don't trust package systems so much. They may contain errors.

Re: Arch seems to think that my wlan0 isn't a wireless interface anymore

Firmware isnt compiled eox425 (or at least, we don't get the source to).
