Wireless card does not appear in lspci

Hi,
I had just installed Archlinux to try it. I was previously using Debian Lenny and the problem showed when I was trying Ubuntu 9.04 and repeated itself when I installed Arch to try to solve it.

My wireless card, which I know is an Atheros AR5007/AR242x don't seem to be detected at all. When I run lspci I got the following:

No wireless device shows up. The weird thing is when I was running Archlinux from the cd and did 'lspci' the wireless card was there (which is what gave me hope to make it work with arch).

I tried compiling and installing the madwifi driver and put the ath_pci driver on the modules section on /etc/rc.conf but nothing happened. It seems to be some deeper (or very simpler) issue.

My laptop have a led to indicate if the wireless is on. The led is lit, so I think the card must be on. It also have a button to start/stop the wireless card but that never worked on linux (it only worked in the original windows vista that came with the notebook). I tried pressing the button to see if something happen but I got nothing so I think it's not that simple.

Some more info to help:

[calsaverini@mnemosyne ~]$ lsmod | grep ath     (of course this is here just because I told arch to load ath_pci driver at startup)
ath_pci               251088  0 
wlan                  257376  1 ath_pci
ath_hal               328816  1 ath_pci

[calsaverini@mnemosyne ~]$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

No ath0 or wlan0 interface shows up.

I really don't know what happened. A colleague had the same problem when he updated the kernel but until yesterday I had a really up-to-date Debian Lenny on the same laptop and it worked very well with madwifi.

Thanks for your help.

First of all:

http://wiki.archlinux.org/index.php/Wireless_Setup

Does the Livecd/Debian use the same driver for it ?

What's the output of dmesg, and what's in the syslog, any related information ?

Something very weird must be happening. I just leaved the computer to rest overnight and went to sleep and now the wireless card is being detected and appear lspci.

Sorry for bothering you... must be a hardware problem or just a very stupid thing I did without noticing. Anyway, thanks for taking your time Djszapi.
