3Com WX2200 Firmware Upgrade

Hi,

It appears our firmware on our 3Com WX2200 controller is not compatible with Vista and this can be fixed by upgrading the firmware, however I cannot figure out how to do this. I have the upgrade from 3Com, but see no way to apply it as I don’t have the Wireless Lan Switch Manager(3WXM). I downloaded a demo of 3WXM, but it refuses to connect to my switch. Any help would be greatly appreciated.
