I installed ubuntu quantal 12.10 to test wireless, and also with kernel 3.5 I have connection drops that force me to restart the laptop.
I found that if I simply restart I get the wifi crash in the first 60 seconds of network activity. It seems that powering off, waiting 10 seconds, and rebooting delays the connection drop.
The time before the connection drops is also correlated with the amount of data transferred on newtwork and with the signal strength.
Each time the connection crash the first log entry in dmesg is
[] iwlwifi 0000:01:00.0: fail to flush all tx fifo queues
Now I installed the kernel 3.9.0-030900rc4
The wireless crashed again, forcing to reboot, but only a couple of times in several hours under high network load.
The bug is still present but now the wireless is usable. I get a different, very verbose, dmesg output, so it could be possible that this is a different bug with the same effect, and the first bug is fixed.
Tomorrow I will test on a network with a weaker signal strength.
