I've had a similar problem. Starting with 3.1.0, iwlagn would sporadically
'drop' connections, despite sill appearing to be connected (nothing obvious in
dmesg). Cycling rfkill would bring it back for a while.

I recently came across another topic, with the same issue, and this patch was
recommended:

http://git.kernel.org/?p=linux/kernel/git/iwlwifi/iwlwifi.git;
a=commitdiff;h=5dcbf480473f6c3f06ad2426b7517038a2a18911

I applied that on top of 3.2.6 and *knock on wood* I haven't seen the issue
reoccur.
