I am no internet security expert; my knowledge is pretty limited. But it was my understanding that WPA/WPA2 is far more secure than WEP. Thus I was told that given the choice, you should always use WPA. So that is what I set my home network up as. But the Nintendo DS doesn't like WPA. It won't even talk to it; using the WiFi on the DS requires WEP. Does anyone know the reason for this? It seems to a layman's viewpoint a very poor choice. There seems to be no good reason not to support both WEP and WPA/WPA2. I'd love to hear a good explanation.
