I have a similar problem.
My MSI M670 laptop has a Ralink RT2561/RT61 wireless chipset inside. Right now I have Linux Mint 13 Cinnamon installed with default stup from DVD (no updates done from internet during or after installation).
I'm not very familiar with linux basics, but I've been using desktop versions of linux (on this laptop)
for about 1 year (Ubuntu 11.x, Ubuntu 12.x). I have been using the same TP-LINK wifi router model TL-MR3420 for about 2 years, no issues.
But since about 3 weeks, I erased Ubuntu 12.04 LTS (which was working great on this laptop, no issues with wifi in my setup), and I installed many other linux versions, for comparison/testing (Lubuntu 12.10, Ubuntu 12.10, Linux Mint 13, Linux Mint 14). Each of them gave me issues after instalation when I tried to use wifi on my laptop and my router (same previous setup which was working OK).
I read on this forum and other forums about many users having difficulties with this issue lately: the laptop connects OK to router (with correct WPA2 password), then it disconnects after 1-2 minutes.... then it tries to reconnect forever... it asks again for password... I reinsert it correctly... retrying to connect... does not connect
... then is asking again for password... and so on... forever.

On this laptop, in WinXP (I have dual-boot Linux & WinXP), on the same router (same setup) everything is working perfectly, the laptop never disconnects from router.
I have no ideeawhat's causing this issue that literally prevents me from using Linux anymore. And I love linux, and I'd like to use it everyday, but this issue is so frustrating.
Unfortunately, I know almost nothing about linux kernel, linux commands, etc. I'm just a regular Windows user for 15 years
. But I'm trying to use linux as much as possible.
So, does anybody know what happened in last kernel versions? Is something changed that prevents wifi to no longer work as it uset to (with some chipsets)?
I have this setup right now:
