If you've got WiiConnect24 hooked up on your console, it should be glowing blue right about...now, with Nintendo having just pushed through firmware update 4.1
Unless you're adverse to this type of business (ie you're the homebrewing type), you might want to grab it, especially if you're planning on getting Wii Sports Resort, because when 4.1 was released in Japan earlier this month, that's what it was for. To fix a bug in Wii Sports Resort. Can't imagine it being much/any different for Western Wiis.
