Good evening,
I use ArchLinux 64bits, my system is up to date and I bought a WiFi PCI card (TP-LINK WN851ND). The drivers are in the kernel : ath9k.
I had to remove the card because I had some freezes short time after booting KDE. Now it seems okay so far.
The computer completely freezes, I can't even access another tty, I have to hard reboot.
I configured the wifi with Newlan from AUR and netcfg (I tried wicd at first and that's when the crashs began so I uninstalled it and I tried with newlan).
I tried to grep for errors in /var/log/ but there is too many errors and I don't know what exact terms I should look for to find the problem.
For the moment, I have a wired connection so it's okay but I would prefer to have the WiFi too.
Another thing, I have Gnome on my laptop and there is the network manager where I can configure everything network related (openvpn, wifi, wire, ...). Is there something similar for KDE ?
Thanks a lot.

Okay, apparently, it's not the drivers. I put it back and booted and it works fine.
# lsmod | grep ath
ath9k 87407 0
ath9k_common 2096 1 ath9k
ath9k_hw 347154 2 ath9k_common,ath9k
ath 14802 3 ath9k_hw,ath9k_common,ath9k
mac80211 228527 1 ath9k
cfg80211 172260 3 mac80211,ath,ath9k
Maybe there is a conflit ? How can I find all the packages related to network (networkmanager, wicd, netcfg, ... ?).
Here is my DAEMONS from rc.conf
DAEMONS=(hwclock syslog-ng dbus network dhcp4 openvpn crond kdm)
I can see in the rc.conf archwiki that I can create profiles for my connection. I created one for my wifi but not for my wired one. I never needed it. Should I do it now that I also have a wifi profile ?
Thanks !
edit :
I tried to setup a profile for eth0. I changed the daemons to something like !network net-profiles ... but I got a freeze when loading KDE, I couldn't reach the desktop. The wifi wasn't activated at that time.
I use a script in rc.d called wifi but it was not activated in the daemons : !wifi
cat /etc/rc.d/wifi
#!/bin/bash
newlan -u wifihome

Hi,
I removed networkmanager and networkmanager-openvpn because I don't need them. I tried to boot in runlevel 1 and just started the wifi.
I updated my system (just chromium and another package) but it was slow (maximum 100ko/s instead of 800ko/s and I wasn't connected to a VPN).
After a while, I tried to edit /etc/rc.conf and I got a freeze so at this point, can I be sure that there is a problem with the wifi card kernel drivers ? I don't know what other things it could be.
I'm trying to find the errors in /var/log but nothing helpful so far.
Thanks.

Okay, I have some news again.
I bought the same PCI card (TP-LINK WN851ND) twice. One for my main computer (ArchLinux) and one for my server (Debian).
I installed it on my server and configured the wifi with the debian documentation. It worked but after a while, I got the same freeze I have with ArchLinux and my server doesn't have any desktop environment.
The problem is that I can't find the damn error in the folder /var/log. I even moved temporarily all the logs in a folder and started the wifi again the make my computer crash but nothing in the log (nothing I would understand as the problem of course).
Does somebody have an idea to point out what the problem is to help me fix it ? I don't think it's a conflict, I think it's driver related but if I have to submit a bug report, I need to give the developers something to work with.
Thanks a lot.

Hi,
I still have my problems. I submitted a bug report in the wireless-kernel section : https://bugzilla.kernel.org/show_bug.cgi?id=42903
So in summary, the computer freezes with ArchLinux, Debian, Ubuntu Live CD. I tried with compat wireless for ArchLinux so I have the most updated drivers. I can't get the netconsole system to work unfortunately. When the computer freezes, I don't see anything on the remote login terminal.
Does anybody have an idea to help me find out what the problem is ?
Thanks.

Hi,
for those interested a patch has been created. I didn't test it yet but a developer seems confident about it.
The bug appears with something related to TKIP for the wifi.
Please find the patch in the bugreport I submitted.
