I believe the good news is that the card receives association with the AP, the bad news is that´s all
Because there is still no actual internet connection working there. In YAST the card is set to DHCP. Scanning is working properly both in konsole and KNetworkManager. The latter can´t establish connection either. I tried disabling eth0, but to no avail. Any hints what I should be looking for/at are greatly appreciated!
Thanks

EDIT: Looking at the increasing nwid I don´t want to believe that madwfi cannot handle some sort of overtraffic in the channel. This shouldn´t be a problem, right? (Apparently, it´s not an issue under Vista.)

lol, that card is really giving you problems no matter what you try!

Yes, it´s almost tragicomic
and it´s also embarrassing to spam the forum with it anymore
If I find any working solution to this, I´ll post back. If that´s my last post here, I might have gone kill myself!

Are you using the madwifi drivers or the Suse 11.0's ath5k ?
Mine is an atheros, the networks would show up but would not connect ( fail to get an ip ) like your case.
Following this link , I have everything working now.

Thanks for your reply and for the link. I have already blacklisted the ath5k driver before installing madwifi. lsmod | grep ath5k has no output in konsole and rmmod ath5k says there is no such module. So I don´t thing the ath5k is here really the problem, but I´ll check that out again.
Also thanks for the link! It´s worth a try, I think I may be doing something wrong in the YaST2 part.

once you have the madwifi drivers complied and rebooted.
Do a modprobe -a ath_pci, then check if you are able to see the wireless networks on command line.

Without first configuring the wifi card in YaST2 I´m not able to see the wireless devices in konsole even with the ath_pci module loaded.

Try a
Have you isolated if this is a dhcp client problem or if your card simply can't pass traffic by setting a static ip?
If you do isolate this to dhcp, fwiw on my x60s's Atheros card I sometimes can't get leases when moving around unless I kill the dhclient tied to the interface. I am not suggesting that this is an Atheros specific problem, only that I never did this with Intel 4965 on my x61s (though the Intel tends to disassociate with APs). Anyway, try this, which gracefully kills any dhclients, clears all lease info (the dhcpd server will parse its dhcpd.leases on the client request, anyway), sleeps for a second, then starts a new dhclient. Totally jank and lazy, but a series of steps that work for me when I move around from AP to AP.
Code: Select all
for i in `ps ax |awk '/dhclient/ print $1'`; do sudo kill -15 $i; done; echo "" |sudo tee /var/lib/dhcp3/dhclient.ath0.leases; sleep 5; sudo dhclient ath0
(You could set that as an alias in your .bashrc and if your sudoers are set correctly, only need to use your password/fingerprint once when calling it.)

Update: I installed yesterday a fresh copy of OpenSuse 11 32bit. Then: compiled madwifi -> installed madwifi -> blacklisted ath5k -> rebooted -> able to see ath0 and wifi0 devices in terminal (without
modprobe ath_pci) ->
iwlist ath0 scan lists the available networks for a few minutes (but NetworkManager doesn´t see any) -> in a few minutes
iwlist ath0 scan output is
ath0: no scan results 
All that was before configuring the network in YaST2.

lightweight: This could be very well an issue with the dhcp client. I found a post on another forum describing exact the same problem on a ThinkPad with Atheros chipset and suggesting that replacing dhclient with pump solves the porblem. I´m going to try this out when I´m back home and have an ethernet cable.
Also, I don´t actually move around, I have placed my laptop where I get the strongest signal, but I´m going to try killing the dhclient.

Off topic: I made some research on the ThinkPad Atheros chipsets and it seems that not all ThinkPad a/b/g cards are the same, even though the chipsets are all identified as AR5212 in Linux. So, it could be indeed the card that is not fully supported by madwifi

two cents: using madwifi 0.9.4 on 2.6.25-2 and need ath_pci loaded, or else my Atheros card becomes unusable.

I usually modprobe the ath_pci module, but it seems that even without typing this in the terminal the modules ath_pci, ath_hal, wlan and ath_sample are loaded after reboot. At least they show up altogether with lsmod.

Sorry to revive somewhat old thread. but here is an
Update: A few weeks ago I found out that Mandriva 2008 Spring edition works flawlessly with my Atheros-based wifi card delivering really very impressive signal strength and ranges! However, updating the driver made it behave buggy. So, my assumption is that my issues with that card under Linux came somehow from the madwifi version which maybe was way to advanced for it or just not really that compatible... Anyway, I´ll be happy if someone could tell what the version of the madwifi driver is that Mandriva 2008 Spring comes with per default, so that I may try it out in other Linux distros (actually, I would stay with Mandriva, but for some reason it didn´t like my ultrabay drive, I guess I should have checked the permissions...)
Thanks

In what way did Mandriva not work with your ultrabay drive? Are you talking about an optical drive or hard drive? Was Mandriva located on the ultrabay drive?
The file in Main Release is: madwifi-source-0.9.3-3mdv2008.1.noarch.rpm
All the madwifi-kernel drivers in Main Updates are version: 0.9.3.3-5.r3114

I forgot to mention that the drive was/is a hard disk. I had Mandriva 2008 Spring installed on my primary HD. If I remember correctly, it told me that it could not access the ultrabay HD. That´s why I think I hadn´t set permissions properly. In fact I had moved all my data onto that drive in preparation to abandon windows and move completely to Linux, but to be honest, with this message I got scared not to lose my data as the ultrabay drive was my only backup since the other one had been formatted by Mandriva, so I didn´t try to work out the permissions (at least, that´s my guess why it didn´t work...).
Thanks,
Marin

As for the ultrabay HD, now when I think again about it, I´m really not sure if it wasn´t indeed an active partition with windows installed on it
I don´t know if that would make any difference for Mandriva Linux though... Also, I believe I put it instead of the DVD drive after Mandriva had been completely installed and after a few runs of it. I did this while my ThinkPad was powered off (not rebooting!), but I guess this doesn´t work like in Windows, so that might have been well the reason as well.

I don't remember the details exactly, but you go into MCC (Mandriva Linux Control Center) and under Local disks expert mode, add read/write permissions for all users. You might need to install ntfs-3g as well. You need to reboot for changes to take effect.

Hm, ok, thanks for the information, I will need it the next time I come back to Mandriva
