ok it seems that the rt2870sta driver in 10.04 does not work with wpa_supplicant. So what i did was to download the driver from ralink and configure it with wpa_supplicant and reinstalled it. This has worked for many people in 9.10 apparently and it seems to work in 10.04 as well. Take a look at http://swiss.ubuntuforums.org/showthread.php?t=1382798, it worked for me.
