Though appears to be very simple, I'm getting stuck up. I want to connect my WiFi router to the office LAN so that I can access the net from my smart phone through WiFi. The Delink ADSL 2730U modem-router I want to use has a default IP address 192.168.1.1. I'm able to get access to the router default website only when it is connected to the telephone line but not when connected to the LAN. However, my PC is working fine with the router, with the LAN inserted into one of the WAN ports. . So how do I configure my router and the smart phone?
