I've recently had a similar problem with a desktop machine running Mageia 4, using a Ralink RT2500 pci card. It would continuously drop and re-establish the connection, throwing up a train of annoying error messages on the desktop.
I found this thread after Googling for an answer. I have now turned the power management off, as suggested above, and since then the connection has remained stable. I haven't tried rebooting yet, so I don't know if it maintains that status, but if not, it should be a simple matter to add a couple of lines to the bootup scripts to turn the power management off on each reboot.
Many thanks for the solution to this annoying problem!
UPDATE: No it doesn't maintain over a reboot, but if you go into the wireless advanced configuration page, you can add extra iwconfig parameters there. I'm using KDE and Network Manager. Adding "power off" (without the inverted commas) to the "iwconfig command extra arguments" box seems to have completely solved the problem. I didn't need to fix the Tx power.
