EDIT: Well, um, uh, having re-read your original post (that kinda, sorta, has the messages you are receiving in it), just maybe, perhaps the angle my thought was approaching has ricocheted off and hit me in the head - right where the anvil left off. I also have a Wii and it has a setting called "something something something" and it is related to the Wii 24 option. When momma Nintendo is not interested in talking to baby Wii, she turns off the wireless connection. When momma Nintendo wants to talk to baby Wii, it fires it back up, changes baby Wii's diaper and turns the wireless off again. I reserved an IP address for my Wii and I also added it to my list of allowed MAC addresses in the Network Filter which is probably why it refers directly to the MAC address in question. Maybe not. It's my uneducated guess. Do you use Network filtering? If not, why not? Do I have to come down off of my high horse and thump you? Ok ok, you don't have to reserve an IP address but if you are not using MAC address filtering, try turning it on (be sure to add your wired connection first!) and see if your messages don't change to what I showed above. If none of this applies, I deserve another anvil.
