Topic: 3DS won't connect to WPA wi-fi

I am trying to connect my 3DS to my home wi-fi. If I go through "Search for an Access Point", it asks for a WEP key, even though the network uses WPA2, and doesn't let me change this, so it won't recognise the passcode even if it's correct. If I enter the SSID manually, it just doesn't connect at all. Is there a way to get around this?

You may have to manually put in the information

I already said that this method simply does not find the network.
