its not actually connecting at that speed, that's just what the computer is registering it as.
I'm assuming you are using USB tethering. to check your speeds, try testing at dslreports.com under tools or speakeasy.net
if you are using BT tethering, it will be slower than usb tethering due to limit of speeds.
but if you are using usb and you are talking about the little bubble that pops up on xp on the status bar in the lower right corner, disregard it.
