I know that. I already did. BUT how does it actullaly work like transfer data?
yes
no it doesn't
Any available USB port should work.
dont know certein area
You can use it to charge your DSi from a computer. It is a cable that has a usb (pc) connector on one end and a DSi connector on the other end. Your computer needs to be on for this to work.
nobody knows charlie...
Yes, the computer does need to be turned on for the Nintendo Wi-Fi USB Connector to work, as the computer cannot communicate with any USB devices when it is turned off. However, a wireless router, which connects directly to a modem, works even when the computer is turned off.
It only supports WPA 2 not WEP or others
Firewalls can interfere with it. But apart from that, it doesn't matter what encryption your router uses, because the USB connector lets the DS communicate with the PC, and the PC is connected to the internet with its own decryption.
Yes.
Try placing the ds closer to the usb wifi connector
No. If you have your own wireless network at home, you do not need the USB connector.
