SlingBox Network Question. Help a Newbie

I recently was given a Slingbox Solo. Currently, I have a Buffalo Wireless router near my pc, and upstairs, I have the Comcast cablebox and a Xbox 360 with the wireless network adapter. What do I need in order to get my Slingbox up and running? Can I somehow utilize the Xbox 360 network adapter? Or should I go out and purchase a wirless bridge? Would the wireless bridge work better compared to the SlingLink? Thanks
