I am running 12.10 LTS and have the same/similar problem.
Connects at boot, remaining strong and stable but after a while, the connection will drop and the system will try to connect again.
This does not happen and after a while, although configured to connect automatically, the pop-up asking to connect (fields are not blank) comes up but connection does not happen and the pop-up comes up once again after a while.
Unplugging and replugging the USB dongle has the effect of freezing the system which requires a hard reset as ctrl-alt-del will not do. Another symptom when system freezes is that kb leds flash on and off repeatedly.

Curiously enough, the hardware data on the label is 'TL-WN822N V2', which apparently has a different chipset.
I have seen this reported elsewhere.

I see this bug was confirmed as being of high imprtance almost year ago (in ~20 days).
Are there any news as to what progress has been made, if any?
After all, it does seem to be a kernel issue.
Thanks in advance,
