Is there a way to do this? I want to cancel my cable internet and use my Sierra Aircard to project a wireless signal from my laptop for our other familiy laptop to use. Want it to be secure also. I already pay $80/month for the service on the aircard and whenever the other laptop is being used, I'm home anyway, so if it could work that way, it would be sweet.

UPDATE: Is this what I want? http://www.powerfulsignal.com/wi-fi-cellular-routers/nexaira-3g-mobile-routers.html Are there recommendations on better ones?
