I can second this. I got back into playing my 3DS last year and was quickly reminded how frustrating it was having to keep your head in the perfect spot for the 3D effect to work correctly. I ended up buying a New 3DS and was blown away by how well the head tracking worked and how big of an improvement it made to the experience when playing with 3D turned on.
You should be able to plug a small switch into the router and then you’ll have more ports available. I’d suggest 1gb or faster, depending on the speed limitations of the ports on the router you could go for a faster switch if you think you’d need it.
