urr there is another way which nobody has mentioned. You dont need to wire two routers together there is no need - it can also creat problems, what you need is just to buy some wierless access points. Set up the access points to connect directly to your actual router and that it your basically set up. All you need to do then is read the manual that comes with the access point and do a bit more configuration and them when your wireless device is on depending on which its nearest to it will either conncect directly to the router or the wireless access point.
