I'm planning to get a 360 soon and have some questions about it's connectivity. My router and game systems are in the same room, but I don't think the included ethernet cable is long enough, so is there some sort of additional cable I could attach to it to lengthen it? Second, when I connected my my Wii and DS online, I wasn't able to do so by general means and was forced to use the DMZ. If I were to use a wired connection how would I configure that? It doesn't have it's own IP address if it's wired, does it? My router is a Linksys WRT54X4 if that helps at all. Thanks in advance.
