I'm trying to set a wireless access point with it. I'm running a Debian Squeeze with kernel 2.6.32-5-686. at first i was using the shipped rt2860sta but since it's not a mac80211 driver, i couldn't use hostapd and iwconfig mode master was not working. I eventually installed different stable version of compat-wireless and ran the driver rt2800pci. If i could set a running access point, i often end with an unloadable module whith a ksoftirq taking 100% of my CPU. Once this "ksoftirq" problem arises, there is no way to unload the module. does anyone ever experience this card and make it work fine ? I can provide more information if needed. Lucien.
