You didn't give any detail such as what router and more. The good news is routers for that USB stick are at places like 3gstore.com
I am trying to set up a wi fi network at home. I have a Sprint USB Novatel Ovation U720 stick (Internet connection)
What do I need to do this all the routers I see have an ethernet port for the internet connection. I tried uaing an adapter but the internet is not being recognized.
