[quote name='dothog']Two questions:
1. What's the timeline on Nintendo's official ethernet adapter? The Obscure Facts FAQ says Jan 2007, but it sounds like it'll be a while longer before we see them.
2. Will using a wired connection present any appreciable advantages over sticking with WiFi? I'm willing to plug mine in if it'll make a difference.[/QUOTE]
1. A fellow CAG - sixersballernum63 - ordered a LAN adapter and got it yesterday. So it should be shipping right now. You still need to order it from Nintendo's own online store, but it looks like they are being sent.
2. Not really, but it's difficult to tell. If you have a stable wireless connection - you're close to a router, there's no interference from things like cordless phones, etc - then wireless is fine. Other things to consider include security - if you don't want to mess with the possibility that you could get hacked, and/or you don't have the patience to deal with setting up security, etc.
You really can't tell if it will make a difference or not versus wireless. The best option is to try both if you are willing and make your own decision. The only thing to say for certain is that you can do wireless out of the box, which saves you a bit of cash.
