How do you find your WEP key to connect to wi-fi connection for the nintendo ds?
If you don’t have a wireless network, then you’re actually trying to access a wi-fi network owned and paid for by someone else – if you don’t know the WEP key, then clearly you should not be using them, they are protected and can only be used by whoever the owner allows. Either get your own wireless service, or go to a place that offers free wi-fi, like McDonalds’ restaurants.
