If loading iwlwifi with "11n_disable=1" or "swcrypto=1" fixes, this is already taken care somewhere upstream:
Some bisect done: http://marc.info/?l=linux-wireless&m=132856386525621 There is a patch may worth trying as mentioned: http://marc.info/?l =linux-wireless&m=132889663513703 commit 86f9199668e8035933c9c5a1e42be9de3a320cd7 Author: Johannes Berg <johannes.b...@intel.com> Date: Tue Feb 7 21:18:33 2012 +0100 iwlwifi: fix key removal When trying to remove a key, we always send key flags just setting the key type, not including the multicast flag and the key ID. As a result, whenever any key was removed, the unicast key 0 would be removed, causing a complete connection loss after the second rekey (the first doesn't cause a key removal). Fix the key removal code to include the key ID and multicast flag, thus removing the correct key.
