Today we went to the Verizon store, and the lady there said we could connect our little USB 720 modem from verizon to a router to make a hotspot for our house. Well...she didn't go into detail. How am I supposed to connect my modem thingy to a router while it's still connected to my computer so as to connect to verizon's national access? I'm confused, but would like to have other computers in my house be able to use the internet at the same time.
