Hi: I have two laptops in my one room which are connected with the 4 port router. I have SYSLINK router which is connected with the modem. I have three desktop computers in the other room which are not connected with the internet. My question is how to i connect the desktop computer with the modem or router. The modem is provided by the cable company and for another modem i have to pay extra charges per month. Is there any way if i buy another router and both router can be talk with each other?
