Yeah, when I posted this, I probably should have done a little bit of explaining first. I just remember Ian and others complaining about the lack of LAN port and the Wii only having WiFi. What this is, is simply the ability to connect to the WiFi Connection without using the built in WiFi to do so, but rather through regular Cat-5 cables. It's awesome that it's available, but for some, it sucks that it's an add-on that you have to buy.
