mine works just fine thru all settings, but when you use the usb setting for the first time for WMWiFiRouter or the internet sharing, Windows has to install RAPI Internet drivers to see your phone as an internet connection instead of a phone, and you loose your activesync connection.
the best way to get results is to have the phone unplugged from the pc as you enable and initilize the sharing, then plug it in. it'll see a new device and install (hopefully)
good luck
