The internet on my Wii U works fine and I can play online and all that good stuff. But on the vwii side when i try to play an injected wii vc title online i get an error code. Happened for CoD Black Ops 1 and Mario Kart/CTGP (wiimiifi). I get error code 20100 after mario kart says "connecting to wiimiifi" for a few seconds. My connection in internet settings on wii u has the wii and wii u logo on it so it should my wifi should be compatible with vwii from what I understand.
