I picked up ds' Wii U on Friday and struggled to get it to connect to the Wifi. I double and tripled check I'd done everything right, and then resorted to internet forums.
It turns out this is a common problem, and can be solved by entering settings manually. This was a real ffaff and not at all straightforward.
When you finally manage to connect, it then goes through two rounds of updates which take over an hour
. Well done, Nintendo
So if you want a peaceful Christmas day, get it sorted early!
