That only applies to WiimmFi, not AltWFC.MacroKrome, Deftoner: Not sure if it's the right thread, but if you're using Wii Mario kart, try the PID extractor with your Wii connected to the internet. as far as I know, this extractor uploads the friend code pair so the old profile is usable on the new servers. If it's DS Mario Kart, just delete WFC config, and redo router config!
