I keep getting soooo much errors. From updating failures and some softwares not even loading up. Anyone else having these problems? Maybe it's just my router.

I'd recommend that you call Nintendo if these issues just keep happening, since software not loading shouldn't be a router issue. I haven't had any update failures, but I did have the Rayman Challenge App not load for me twice. But I heard that happened to some other people, so it probably wasn't my console. I also have had my console freeze twice in the middle of gameplay, but that's all the errors I've had.

Haven't gotten too many errors.

You might want to try downloading Connectify.

I use it to connect my Wii U and my 3DS to the internet since I had too much trouble trying to connect them to the wireless router. It works great.
