wireless fails with wpa_supplicant and Intel 4965AGN controller

I've got a HP 6910 laptop that I can't connect to our WPA2 protected wireless.

$ lspci -nn | grep -i wireless
10:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection [8086:4229] (rev 61)

The driver seems to be loaded fine

$ lsmod | grep -i iwl
iwl4965                81035  0 
iwlegacy               41769  1 iwl4965
mac80211              402806  2 iwl4965,iwlegacy
cfg80211              346009  3 iwl4965,iwlegacy,mac80211

I've followed the arch wiki's manual wireless setup steps. I generated my psk with wpa_passphrase, and have set "proto=WPA RSN". When I try to connect manually I get

$ sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -Dnl80211
Successfully initialized wpa_supplicant
wlan0: SME: Trying to authenticate with 24:de:c6:29:e7:70 (SSID='WISE_WLAN' freq=5765 MHz)
wlan0: Trying to associate with 24:de:c6:29:e7:70 (SSID='WISE_WLAN' freq=5765 MHz)
wlan0: Associated with 24:de:c6:29:e7:70
wlan0: CTRL-EVENT-DISCONNECTED bssid=24:de:c6:29:e7:70 reason=3

I get this just repeating over and over again for all the possible frequencies.

If I try and connect with wifi-menu, it creates what appears to be a correct profile, but I get

Job for netctl@wlan0\x2dWISE_WLAN.service failed. See 'systemctl status netctl@wlan0\x2dWISE_WLAN.service' and 'journalctl -xn' for details.

Annoying part is I can throw in a live cd that has Network Manager and it connects immediately. I've been trying for 3 days to find an answer, but need help!

Don't feel bad. After days of trying to get the Wifi working in my Lenovo Thinkpad x61T, you're the first post I've found with the same controller and same exact problem as I. And yes, wifi works from a liveCD just as it should. Is there any chance you found a resolution to this issue?

Thanks,
Sean

Please post the output of systemctl --type=service --no-pager

Re: wireless fails with wpa_supplicant and Intel 4965AGN controller

Just tried to solve this morning on an Acer 5920G and i can teel you how to solve, at least for me it just works. Basically we needs to create a file named e.g. iwl4965.conf and put it in /etc/modprobe.d.
The iwl4965.conf file contains "options iwl4965 11n_disable=1" (without quotes), to disable 11n. I can suggest to moderator to put this workaround in the related wiki page.

Re: wireless fails with wpa_supplicant and Intel 4965AGN controller

Hi Stefano, and welcome to Arch Linux.    Thank you for a good first post with a relevant solution.  Please feel free to put it into the wiki -- it does not require that a moderator do it.

Also, normally we ask that you watch the age of threads.  This one is a year and a half old, although, as our policy states, that relevant solutions are okay.
Does this chip set still require that you disable 802.11n a year and a half later? Yikes.
