I've recently got a wireless internet connection and would like to go online with my consoles.
I was under the impression the Wii came already wireless enabled (I know that an adaptor is needed for the 360).
Looking through the Wii manual it says you need to buy an extra adaptor (not supplied with console) that fits into the USB port of your PC - unless I'm reading this wrong.
Make sure your wireless router is switched on, and fire up your Wii. I can't remember exactly which menu option you select but it's easy to find. The Wii will automatically connect to your wireless network - if your wireless network is protected by WEP or WAP you'll have to enter your passcode/password on the Wii.
