Get my brand new Wii U to stop from losing its Wi-Fi connection and get it to stop having to wait to load Netflix my other systems and TV's have no problem with Netflix.

Go to the Wii Shop Channel, and you should find Netflix there as a free item. "Buy" it, and then you'll have Netflix on the Wii.

Wait, is your Wii connected to a Wi-Fi (wireless network) connection in your home? That's step one:

You don't need Wi-fi specifically, but you do need an internet connection. If you do not have a wireless router, you will need to purchase a Nintendo Wii LAN adapter. This allows you to connect the Wii to a wired router using an Ethernet cable.

You need to have wi fi access-go to wii options- then under the wrench to settings- then to internet connections.Cheers-Denny

11.) click "OK"
12.) click on an access point with a lock that's unlocked, or click on one with a yellow lock and put a password. if you see a red lock, you cannot connect to that access point.
