Unable to set up wifi (ath5k)

Hello,

I'm trying to installl Archlinux but I can't get the wifi working.

I first execute "ip link set wlan0 up" which doesn't return anything (so I guess it works).

Then I try "iwlist wlan0 scan" but I get :

ath5k phy0: failed to wakeup the MAC Chip
ath5k phy0: can't reset hardware (-5)

Does anyone know how I can this working ?

Thanks ! :-)

Of course, here it is :

ifconfig

eth0: ...
lo: ...
wlan0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 metric 1
           ether 00:16:e3:fe:ca:d6 txqueuelen 1000 (Ethernet)
           RX packets 0 bytes 0 (0.0 B)
           RX errors 0 dropped 0 overruns 0 frame 0
           TX packets 0 bytes 0 (0.0 B)
           TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

iwconfig

wlan0: IEEE 802.11bg ESSID:off/any
           Mode: Managed Access Point: Not-Associated Tx-Power=20 dBm
           Retry long limit: 7 RTS thr: off Fragment thr: off
           Encryption key:off
           Power Management: off

lo: no wireless extensions.

eth0: no wireless extensions.

lsmod gives me a too long list to copy, so here are some grep into it :

lsmod |grep ath5

ath5k           128467 0
ath                 12413 1 ath5k
mac80211   341044 1 ath5k
cfg80211      147429 3 ath,ath5k,mac802211

lsmod |grep cfg80211

cfg80211      147429 3 ath,ath5k,mac802211
rfkill                 12568 2 cfg80211, toshiba_acpi

Well...now it works. But it didn't before, even with rebooting (a lot of times).
Could this be linked to the order in which modules are loaded ? (the lsmod I copy in the post before are the one for which it is working)

Edit:

Well...now it doesn't work again. I have this :

ip link set wlan9 up
RTNETLINK answers: Operation not possible due to RF-kill

As I'm on the iso, rfkill is not available...does someone have a solution ? Thanks
