How to install Wi-Fi on the DS

How to install Wi-Fi on the DS I decided yesterday that I am helping a friend with his problem. At one point, he questioned whether I could help him, but eventually I did. When a friend needs to get on the rescue here! This setting is only for the DS is not Wii. I only know how to click the wireless connection and via Nintendo Wi-Fi USB Connector configuration. But if you have any problems with the Wi-Fi will be happy to help.
