Windows 7: Setting up a Wi-Fi connection - How???

I've tried to set up a Wi-Fi connection to use for Nintendo DS/3DS, but nothing seems to work. I don't have a wireless internet connection, so I bought the Nintendo Wi-Fi USB Connector, but that does not work with Windows 7... I've also tried another Wi-Fi USB device, but that doesn't seem to work either. I guess I should get a wireless router that allows Wi-Fi connection, but which would actually work for Nintendo DS/3DS?

Yep...with out a wireless connection to access your wireless devices won"t connect. When you do get a wireless router, keep in mind that some of these peripherals may or may not have built in wireless capabilities. Then you have to get a wi-fi usb connector, in which case you all ready have. Next thing to remember is that you will have to manually add the mac address to to wireless router. Generally, that is done with in the wireless device itself. In my case it was Nintendo Wii.
