Choose on the routers to be your "router" and another one to be the wireless "extender". Turn DHCP off on your wireless extender box. You then need to run a cable from one of the LAN ports on your "router" and plug it into one of the LAN ports on your "extender". Connect JUST the "router" box to the phoneline - ie. the "extender" does NOT connect to your phoneline, just the "router".
This way the "extender" will bridge the connection from your "router" box - the router box does all the routing, IP address and is the only box that connects to the phoneline. The "extender" box has just one LAN connection to it (and power obviously!), no phoneline connection. |
