I don't either but as soon as I plugged that thing in my internet was gone. I'm using a USB 802.11g dongle (as I showed in the USB hub review) and it stopped seeing the network at all. I hooked it up to another PC, it worked fine.
I unloaded it's driver, uninstalled the USB altogether, reinstalled everything and still no love.
It took a full reload before my wireless would function.
