1UP.com has gotten a hold of a Nintendo Wi-FI USB Connector. As such, they've been able to document the simple process of attaching it to a PC and connecting the Nintendo DS to the internet.
"The DS's WFC Connection functionality automatically seeks and locates all available access points, and from there it's a simple matter of entering the HEX equivalent of the network password," noted the author of the article. "Simple, fast, painless."
Check out the full article with pretty pictures detailing the process here. Users will be able to purchase the Nintendo Wi-Fi USB Connector later this month at nintendowifi.com.
