So the Wii U was officially released today, cancelled my preorder as I got it in store(not waiting 3 extra days..) now just waiting on a refund basically.
The Day 1 update will take around 1hr.30Min as it's pretty big, 2GB to be exact.
So haven't popped any games in yet but I'll be playing New super mario bros until tuesday when nsmbu is delivered.
Only way to connect to wifi is through manual config, it should be fixed in the update but can't download without the update

What gives Nintendo?
Just get the Lan adapter and don't worry about the wifi issue.
