I believe I hit a jackpot in saving you maybe around $100 and maybe just spending $25. If you have windows 7 and a laptop or a desktop with a wireless network adapter that receive a wired connection you certainly benefit.  Instead of having a router, just use your computer to create a wireless signal.  To start, you must download connectify at connectify.me.  From here use the software and create your hot spot by naming it, putting a password, and sharing that wired internet. It is that easy, plus it is free! Here is a video from connectify.me with more instructions: [youtube=http://www.youtube.com/watch?v=jPgrAOuiWuk]

Have fun!
