As the topic title already says, the WI-FI of my DS lite doesn't agree with me. Here's the deal: My dad has bought a new router and when I try to connect to WI-FI my DS says the WEP key is invalid. But it isn't. and it gets better! When I put in a WEP key that exists of 5 random digits, its says it's OK, but when I try the connection it says that it isn't the right WEP key! Anyone knows what's wrong?
