Lenovo T61p Atheros 5212 wireless doesn't work


I've read that the MadWifi package is supposed to make this work, but it doesn't work for me. Here is my iwconfig:

~/ar @heirich-laptop> iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wifi0 no wireless extensions.

ath0 IEEE 802.11b ESSID:"" Nickname:""
Mode:Managed Channel:0 Access Point: Not-Associated
Bit Rate:0 kb/s Tx-Power:0 dBm Sensitivity=1/1
Retryff RTS thrff Fragment thrff
Power Managementff
Link Quality=0/70 Signal level=0 dBm Noise level=0 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

pan0 no wireless extensions.

Any suggestions are welcome, thanks in advance.

What do you mean by "it doesn't work" ? The output of iwconfig is correct, you just have to enter connection settings in proper place. It would be useful to know what your distro is and what type of connection you intend to use.

doesn't associate

No matter what settings I enter using iwconfig, the wireless device never associates with an access point. I've set the essid, key, management, etc. There are no errors showing up in dmeg or /var/log/messages. I don't know where to look next.

I'm running Fedora Core 9, 2.6 kernel
/home/heirich/ar @heirich-laptop% uname -a
Linux heirich-laptop.arastra.com 2.6.25.11-97.fc9.i686 #1 SMP Mon Jul 21 01:31:09 EDT 2008 i686 i686 i386 GNU/Linux


thanks

ok
first, post the output of
Code:
iwlist ath0 scan
. if it shows
Quote:
interface doesn't support scanning. network is down
, do
Code:
ifconfig ath0 up
and try again.
the result should show at least your network. if it shows nothing, there's the problem.
second, please post
Code:
lsmod |grep ath
and
Code:
lspci |grep Ath
. maybe you don't have madwifi driver, but ath5k, which is included in newer kernels, but also is a piece of crap
third, tell us what kind of security do you use: WEP or WPA? if it's WPA, you must configure wpa_supplicant, if it's WEP, iwconfig is sufficient, but wpa_supplicant handles also WEP encryption and does it way better.

Here is my output. I do have madWifi installed and (I think) I blacklisted ath5k.

I have to wireless networks, one is WEP and the other is WPA. I have wpa_supplicant 0.6.3 installed.

thanks

according to lsmod output that's right.

here's the problem - card can't detect any network so there's nothing to connect to.

madwifi.org shows that the chip is supported, modules are loaded ok, strange. maybe your networks have hidden SSID - if so, change it and try again iwlist command. i'm running out of ideas, but please post
Code:
lspci -vv
output, but only the part concerning Atheros chip.

ok, my two last ideas:
A
1. remove madwifi
2. download http://snapshots.madwifi.org/madwifi...0080801.tar.gz this version and install (unpack, cd to directory, make, make install) it.
3. check whether ath0 is available and whether iwlist shows anything.

B
try to check with some other distro's live cd, like ubuntu 8.04 - this card should work out of the box in theory.
