If you have a wireless router, that's all you'll need to get a Wii online.
You have to pay a small amount to download the web browser and any Virtual Console games you want, but you don't have to use a credit/debit card for that if you don't want to - Wii points can be bought in shops.
Playing Wii games online is free.
Yeah, I'd need a cable. My router isn't wireless . But thats not to bad. So.. I guess its that simple eh. Awesome. Thanks alot guys When im on Wii Online, I'll let you know
Wii has built in wi-fi but does NOT have an ethernet jack for a wired connection. You need the LAN Adapter that connects to one of the Wii's USB ports. The you plug the cable into that. A cable by itself would be useless.
You don't need too download/pay for anything from the shopping channel, to use the "internet connection". If you want to use the Internet Browser, you need to pay 500 Wii points(value of 5$, minimum purchase online from the wii is 10$ 1000 Wii points).
You can buy Wii points with a credit card on the shopping channel, or pay 20$(plus tax) for 2000 Wii points card from local game stores.
