For my internet connection, I currently have an Actiontec GT704-WG. With this product: http://www.newegg.com/Product/Product.aspx?Item=N82E16833127053 (D-Link DWL-G730AP High Speed Wireless Pocket Router/AP - Retail), will I be able to connect to the internet wirelessly by plugging an ethernet cord into one of my 4-port router to the D-Link Wireless router? Another thing that i'm trying to do with this is connect to WiFi with my Nintendo DS Lite, but my current router is not compatible with the WiFi service. And i'm hoping that the D-Link product will make it possible for me to connect to Nintendo WiFi. Does this actually work, or will I need something else?
