verizon mobile broadband home networking

I’m trying to network a u720 Verizon broadband mobile network card.can anyone tell me if this is possible or even how to do it?I started out networking it with a link systems wireles b router and it worked for about a week then showed minamal conectivity on the other computors in the house after that I thought about trying the 3G en-vo router but i would like a second appinion before i spend 200.00 on a router.
