I have these two wifi modems at my house and i was looking to use the asus modem as a repeater to extend my network's range.. as till now, i have not been able to find a way of doing so.. any help on this would be greatly appreciated!
I don't think that router has the feature you need. Mostly have a function called client-bridge or repeater if they can do it. Normally I would recommend you look into a third party firmware like dd-wrt. Most asus routers support it but this being a DSL device makes it highly unlikely you will find third party firmware support.
WiFi Routers can often have "operational Modes" Router, Access Point, Bridge, and Repeater. Each is slightly different. Do you know what is for which ?
