connect wireless router to cable modem first

using the cables supplied, then fire up both modem and router, check the LED lights, such as "WLAN", "POWER", "INTERNET", if they all light up, flash intermittently, that means they are working properly. "要是我要同时用两台机的话，Notebook
大概只能用wireless而不能用线．不知道我的猜想对不对？" - no, your notebook should have a cable port, same as your desktop. you can connect to the router by a cable, or wireless.
