I'm getting disconnected at least once a day, my connection will drop to 40%(example numbers) back to 84% down to 33% back to 100% and so on and so forth, untill I eventually D/C.

I have 2 computers, and one PS2 hooked thru my router, my PS2 was having the same problem untill I set it up DMZ style.

I have a fair bit of computer knowledge, but networking is somewhat new to me.

Any help?

Before I set the PS2 to DMZ my Wife would be on the PS2, and I would be on the internet looking up quests/synths/random stuff, and that would D/C her.

So then I tested out FFXI on my PC, had a web page in the background that auto-refreshed, and sure enough I would get D/C'd.

I think that's it, if I can think of anyhting else I'll post it, same goes for questions I'll do my best to answer them.
