Sprint wireless AirCard for use on Pc and Router

I have a Sprint Wireless aircard. That I use to access the internet on my laptop and Pc. I would like to use Netflix’s Roku Player. It needs to access the Internet thru an Ethernet connection thru a Router. Is there a way I can use a router or get this Roku player to access the internet. I believe it still needs some type of PC connection to activate the Broadband card. I’m trying to bypass a subscription to a high speed cable internet provider.
