So you have one of those dual-routers where its a modem and router in one? Sadly, based on my own experience, there isn't much you can do besides what foolness mentioned, but even that will be very minor lag increase if anything at all.
The absolute key with lag is doing it behind a router, because when you sever the connection in front of the router, it drops the PS3's IP to protect the rest of the network, which means you lose connection to the PSN. When its done behind the router, the IP is left in tact (for longer at least) and lets you do a little more before the PS3 (or router) realize something isn't right.
If you do not have a dual router/modem...then you must have something besides just a router. Because routers in general (non-dual purpose ones) do not make the internet connection (for lack of better words), they are not designed to do that.
Exacly GJ +rep and i recommend you +rep him as well exacly what I would have said without the grammar xD
