Before downloading, you need to select your OS version (viewable in the Wii's settings menu). To find this, click on Wii Options, go to Wii Settings. After filling in the words, you have a choice between clicking "Cut the red wire" or "Cut the blue wire." I clicked the "red wire" button, but as far as I can tell it doesn't make any difference which one you click. If your Wii is new and you have no messages, create a memo on your Wii before going on to the next step.
Go to page 2 of the settings, then click on "Internet". Enter the Mac Address displayed there in the appropriate area of the website page. To create a memo, go to the Wii Message Board by clicking the envelope in the little circle on the lower right corner of the main menu, then click on the create message icon, then the memo icon, then write and post a memo.
