A more immediate solution could be your choice of router. Our testing has found that in using Telstra broadband Internet service, the on-line multiplayer mode in Wii U is functional with a range of routers, including the small selection of widely available options listed below:
TP Link TD-W9980
Netgear D7000 Nighthawk
Compatibility of Wii U online multiplay and ADSL/national broadband network (nbn) with router firmware confirmed with in-house testing as of 10/7/2015.
Users should consider their online requirements when selecting a replacement router. Nintendo cannot make any specific recommendations. Users should contact the relevant manufacturer for further information.
