You go on a game that supports Wi-Fi then go onto Nintendo WFC settings (it will probably be in multiplayer). make a new wi-fi connection (it is easier to search for one click on the one that is your wi-fi. then follow the on-screen instructions. Hope this helps.
What can detect your DS? Please be more specific. From what I gather, your saying that the Nintendo WiFi USB Connector (WiFi USB) can dtect your DS but not your DS cannot detect 'it'. WiFI USB cannot detect Nintendo DS's unless it is connected to it. So, the Nintendo DS would have to be able to detect the Wifi USB for it to be able to detect the DS. ThE AvEnGeR

Yes
that is just wifi
Indeed-- If you have WiFi with a DSi you can go on the internet.
Yes, you need the Nintendo DS WiFi USB adaptor to access the internet.
for ds and ds lite get a game with wifi connection and select the wifi setup, then search for an access point on one of the three slots. You have to have wireless internet to do this, or the Nintendo wifi adapter, which is kinda crappy.
yes it does
Yes all Nintendo DS's no matter what the version have the abilty to receive WIFI.
