Before I had a WEP security on my router, but the Playstation Network did not work. Right now, I have WPA-PSK, but for some reason, only my computer, Wii, and PS3 work. But on my DS Lite and PSP 2001 do not work. It's either that it cannot obtain the IP adress or it cannot find it at all. So I'm planning to change my security settings back to 128-bit WEP. Is Playstation Network going to work? Thanks in advance.
