Yea I learned this sadly my 3DS and 2DS don't suppot N but everything else in my home does .. and oh dear yea my router is literally right next to my bed o.o my home is small so my router is not thta far from my living room but id be using the switch mainly portable so i can just easily switch roomsI seriously doubt it. Also, bear in mind that if you have any older devices that don't support N they won't be able to connect.
The Switch's networking is crap. Both wired and wireless. It all depends on if the Switch "likes" your router. Even if it does, expect the Switch to perform worse than any other device on your network.
