glad to hear the new unit is good. reassures me that it wont be some strange enviromental circumstances causing the issue.

I just came back from returning it.
actually had to convince the store it was faulty as they havent heard of any issues with the Wii U yet.

got the replacement now but will need to wait until tonight to see if the problem is gone. not looking forward to doing the 5GB update again
going to need to wait till off peak times as my peek internet quota is almost gone.

completed the update on the new console last night and it all seems to have gone fine.
i have a fully functioning (or at least as much as it can until the next update) Wii U
and it even turns off when you press the off button.

i was disappointed to find that the usb i formatted and the save games i copied across dont actually work on a different console.
i had also linked my new console to my nitendo account and apparently you can link multiple consoles to an account or remove a console either

Hmmmm, thought it was a soft press to reset and hold to turn off like Wii - but either way the standby light comes on for half a second and then it just restarts - am I doing something wrong? The only way to turn it off is o take out the power cable - that can't be good.

Oh great - now I can't connect online after the update. It updated fully but now won't see ANY wifi connections at all - keeps coming up with error 103-4199. Possible lemon here.

I have this EXACT same problem. both the power button AND the wifi with the error code

i have been surfing the net all weekend trying to find a solution and hadnt found anything even close to this problem. I also had to wait till today (monday) to call support. (in australia)
They had no idea and i have an in depth trouble shooting session scheduled for tomorrow morning with their network guy (dont have high hopes)
will post back as soon as i get any answers

• well that was useless. nintendo support has no clue.
• i will be returning my wii u today and hopefully get a replacement, if the store actually still has any stock
