Long story short, I got the "official" lan adapter for the Wii/Wii U to make things easier and at the very least have an stable internet connection.
The problem being that my connection doesn't work properly and as I try to download a game from the e-shop (DK Tropical Freeze) I keep getting the error 108-0075, this error code appears when the Wii U console is unable to connect to the server during the system update download.
Are the servers of Nintendo getting an overload? or my 200mbps are too slow to handle the download?
I'm getting a bit frustrated with this, is been two days since I got this game from the e-shop.
Also I should point that this doesn't happen with my other consoles.
Please help this poor soul in despair.
