Description:
On kernels 3.6.* (3.6.2-1 and 3.6.3-1 tested) the iwlwifi driver crashes when attempting to authenticate with an AP using WPA. Wireless NIC: Intel Corporation Centrino Wireless-N 1000 This has been confirmed with other models, see: https://bbs.archlinux.org/viewtopic.php?pid=1176708 Disabling 11n in /etc/modprobe.d/modprobe.conf with: options iwlwifi 11n_disable=1 Seems to create a temporary fix. Additional info: See klog.txt (kernel trace) and iwl.txt (iwlwifi driver errors) Steps to reproduce: Boot machine and attempt to authenticate with an AP using WPA |
This task depends upon
Hardware is:

Disabling 11n in /etc/modprobe.d/modprobe.conf with "options iwlwifi 11n_disable=1" didn't help at all.
My Wireless card : Intel WiFi Link 5100.
My wifi card is Intel Wifi Link 5100
- activate mac address filtering on router
- uninstall netcfg with -sn options
- took wlan0 down with ifconfig because it kept staying busy even with the netcfg commands
- install network-manager
- set up a new wireless connection with wpa encryption
Maybe that can help somebody.
system info:
system:Linux LM 3.6.6-1-ARCH #1 SMP PREEMPT Mon Nov 5 11:57:22 CET 2012 x86_64 GNU/Linux

Thank you very much!
from time to time network freezes, workaround 11n_disable=1 as before
hardware: intel wifi-link 1000 bgn
I downgraded back to kernel 3.6.2.1 in the meantime to make it work again.

Same issue:

Kernel driver in use: iwlwifi
Also, isn't this the same bug as https://bugs.archlinux.org/task/31667 ?
I had more of one service that tried to manage the wifi.
I solved with:
systemctl disable NetworkManager-wait-online.service
systemctl disable net-auto-wired.service
systemctl disable net-auto-wireless.service
Now all works fine.
Sorry again
