Wii-U Controller not connecting to Console.

Hola all,

Ive had my Wii-u since launch, and haven't had any issues with it, until yesterday, when my gf was playing a game, she kept getting a popup msg on the controller "The connection with the wii u console has been lost." We both thought perhaps we wernt close enough to the console, or something was in the way, etc etc... but then I thought, hey the consoles been out for over a week now, we both play it exactly in the same area/room/location, we have in the past... and had no issues as far... why it is suddenly doing this... We turned it off, and went to bed... I woke up eager to give Zombiu a play... and kept getting the same msg... Making the game impossible to play.  2 of my best mates work at EB games (Aust version of Gamestop) I msg them asking if they knew any ideas on how to stop this, both suggested resyncing the control to the console... Upon doing this I was greeted with a msg saying its already synced.... killing that idea dead in the water.

I have heard reports of consoles bricking when updating via the net if the net drops or there is a black out, and until today haddent tried.. due to my net being unstable and prone to dcing in my area.  1 of my mates suggested trying to update the console, and seeing if that helped at all... Reluctantly, I did... The DL got just over 1/4 way through, and my controller switched off...  I turned it back on to be greeted with "Could not connect to the wii u console, Turn off Gamepad and turn it on closer to the console"  Ive tried this over 20 times as far.... to the point where if I were any closer, the controller would become part of the console itself... and still get this msg... making the controller useless, and not able to see the progress bar on the DL.

FINALLY the dl finished, and on the TV, prompted me to press OK... problem being the controller not working anymore.

I tried to resync... and managed to get the syncing pattern (Diamond, Spades, Clubs and Hearts, prompt on the controller) but since its in the Updating prompt process on the TV, it wont come up with the combo I need to sync.  Placing me back at square 1.

Logic told me.. switch off the console, and try resyncing it from there... the DLs finished, so there shouldnt be any bricking issues... BUT in saying that im worried that if I do turn off the console, SINCE I havent gone through the full update after prompts... if it will error and brick regardless....

Any help would be muchly appreciated.

Thank you.

Got the update all finished.... But the controller keeps doing the "The connection with the wii u console has been lost."... any ideas how to fix this?
