there are two different ways:a)Buy a wifi connector and connect it up to the computer b)buy a wireless router for your computer.
1. Well first you have to created an account on the Nintendo wifi home page. 2. Now you need to buy a Nintendo wifi USB connector, (if you don't have wireless broadband) 3. Finally configure the settings and then connect your NDS to the connector and your away! 4. Have fun!
It is to do with your wifi settings. You have two options. 1: Change them. just go to Nintendo website to see how 2: buy a Nintendo Wifi Usb Connector. This will work for a wii and will give a stronger connection to your ds/wii Hopefully this helps BTW For more info about the Nintendo wifi usb connector goto: http://en.wikipedia.org/wiki/Nintendo_Wi-Fi_USB_Connector
You will need to buy either a wireless router (from any good computer and electronics stores), or if you have Windows XP, a Nintendo Wi-Fi USB Connector (from a game retailer or direct from Nintendo).
Well not all gamestop's sell them. So you have to check online 2 see what gamestop has it. Also you can buy it on Ebay, not Amazon because they overcharge you for it.

Ebayor some sort of internet sight?
You can buy a Wi-Fi USB connector from Nintendo; you place it in a USB port on your computer and it broadcasts your internet connection to your Wii. You can also buy an ethernet modem and get the Nintendo Wifi ethernet adapter and hook up your Wii to the internet. You have to have a cable or telephone jack around though to do this.
