Ever since March, my Wii U started giving me the error code 118-0516. I used to have it in the past, but then I had to factory-reset my router and... well... it began to do that stupid error thing again. I looked it up, it said it had to do something with the NAT settings. I did everything they said. DMZ, Port Forwarding, and that next stupid thing. Nothing is working.
PLEASE HELP. I've already missed out on both Splatoon events so far because I wasted the hour trying to fix the error. I don't want to miss the last one going on today. Please help...
I have a Netgear CG300D-RG router.
