Help/Advice Needed

Hello. I'm hoping you guys can give some much needed advice. I apologize for being a wireless novice, but I just cannot seem to find a similar setup to mine documented anywhere online (even though it seems like a fairly common setup to me).

Here is what I have...

My cable modem and wireless router are on one side of my house. This PC is also on that side and is WIRED to the wireless router. On the other side of the house is my A/V center which has all internet-capable devices, but NONE have built-in WiFi capabilities. There are 5 devices that I want to connect (Xbox, TV, Blu-Ray player, D*TV box, & Receiver). NOTE: I can live without the receiver being connected, but the other 4 devices are a must.

What is the best/proper way to get all of these devices connected to my wireless network, keeping in mind that the 5 devices are WIRED? Do I just buy a 2nd wireless router and connect the 2 routers wirelessly?

Thank you

Thank you, Irish. Yes, you had it right, I do not want to run any wires. Unfortunately, my house was built in the mid-60's, and they used plaster in here instead of drywall. So running cables is not quite so easy...even just across a single room.

So using the 2nd router in "bridge" mode is the key then, correct?

That is obviously the easiest & cheapest solution, but just out of curiosity, could I also by a single little wireless bridge (w/ 1 port) and connect a multi-pot (4, 8, 16, etc) switch to it. Then just connect the wired devices to the switch?
