What do I need for the desktop. What do I have to do to Win7 to recognize the hotspot?
You need a wireless network card if the pc doesn't have one built in. Once you activate the hotspot on your phone, your of can look for that network (emitted from the phone), but the pc has to have wireless network capabilities, or you will have to buy a wireless usb card (they are about $30 and look lime a little flash drive)
