WPA and WEP are two different kinds of connections.

A WPA connection is considered stronger than WEP. A WEP is considered to be a basic encrypted network. Both of which can have passwords.

Anything that has a lock definately has a password. Anything that doesn't have one is an open/shared connection.

This is why a DS will connect to a WEP and not a WPA. However, a PSP will connect to a WPA since it's technology is more recent than the DS.
