|The easiest way is, to have 2 wireless routers, the main router that is connected to the internet, and another SOHO router, that supports repeater mode.|
Running the second router in repeater mode, it can connect to the main router like an ordinary computer, by configuring SSID to connect to and the encryption type and key.
In this scenario, the router running in repeater mode, communicates with the main router as well as with the client computers. It creates no additional wireless network.
It's also regardless, to which router the client computers are wirelessly connected to.
