ya that sounds easy!!! I will be able to manage. So I understand that - the main DSL goes to the wifi router, the I have 4 ports free. I can use 3 ports to connect 3 rooms and use the 4th port for the switch - and then the other 3 rooms get connected to the switch.
That way all rooms are wired. And since our house (in India) have many brick walls, can I put my old wifi router(Linksys) in a central lobby to give the wifi to the back side of the house? will a second wifi router interfere with the IP address the main router allocates?
Thanks!!!
