If your trying to handle more WiFi clients and additional APs, it would be best to use a host router then add additional APs and use DLink model DAP's to do this, i.e. DAP-1360, DAP-1522 or DAP-1525. Having additional ROUTERS will introduce setup issues and all the features that ROUTERS have will not be used in come of these situations. ROUTERS are meant and designed to be HOST ROUTERS to provide an initial point of access to the internet and not as 2ndary APs. DAP models help in extending, bridging and in some models, relaying WiFi while using the same SSID and password information. If your using some of these ROUTERS and have more than 10-20+ wifi clients, it might be best to get into a enterprise or business class AP to help handle your wifi needs. I would contact DLink sales and ask about this.
