You need to get a router that has more then 1 Ethernet port on it. You can't use your computer to hardwire the Roku. A router can be picked up fairly cheap these days. Go to the Roku DVP forum and look for the compatible routers post, any model mentioned there should do the trick for you. If you have questions about how to set it all up, post them there for better response. This forum is for general things not related to any specific Roku product.
