Thanx to everyone who is trying to help.
I think i will say this again to make it absolutely clear, I Cannot move the router as it is wired to a device that has no wireless capabilities and I Cannot move the ps3 as its connected to the only TV that has a 5.1ch surround sound system (yes not quite an excuse but once you have played in true surround sound, you don't wanna go back).
I'll say it again THE ROUTER NOR THE PS3 CAN BE MOVED
On another note, this thread is not about what works for you. I don't really give a monkeys if you have a perfect signal, use cables, have blue hair, are the son of a frying pan or live under a lamp shade. This is not a thread about what different people use, this is a thread about troubleshooting an issue. If you have the same problem, sure post a description about your setup etc, but if you don't have a problem and you are not helping please don't post.
Thank you everyone who is helping and if anyone ever finds an image please post-it.
