basically it uses the local wireless network to download the image from the wii to your laptop.
This does not affect your 'internet' traffic as its all internal data transfer and sends from your wii to your router to your laptop.
Going on the internet takes up a tiny bit of bandwidth which should be practically unnoticable to you while your getting the ISO from the wii.
Best thing to do is to try it and see but it wont make much difference.
Clarky , your seriously on the ball with helping people here - well done.
