PS3 disconnecting me from FFXI

[GImpers]

When I turn on my PS3 and it connects to the internet, it disconnects me from FFXI. The internet on all my other computers work fine. My brother plays WoW while I'm on the PS3. However, I cannot be connected to FFXI and PS3 at the same time.

I'm sure it has something to do with how my router is setup, but, I'm an idiot when it comes to that stuff.

Anyone have any ideas why my PS3 disconnects that one computer form the internet?
