Hey, I was having this problem too.... I borrowed my brother's Wii for a few months when he was away at college.... It got to the point that I would get about 5 emails or more a day from the router because 'log is full'. The problem is the Wii Connect 24 option on the Wii. I just turned it off, but that made the Wii unable to get to certain services online, like weather and news. I would look into it more, but I gave the Wii back already since he is home for the summer.
