Everything should be connected. Not having the modem connected to the router may cause the issues your having because the router cannot complete it's functions.
First, unplug the power to both the router and the modem and turn off your computer. Then reconnect the power to the modem first, then the router. The two will go through some LEDs blinking, etc. The two are "shaking hands" with each other. After about a minute, restart the computer and see if your LAN icon in the Windows 7 System Tray (lower right-hand corner) is connected to the router.
Is your ACER connected to the router by an ethernet cable or is it wireless? Do have both a LAN network connection and a wireless connection on the ACER?
It is preferable for the main computer to be directly connected to the router via the LAN ethernet connection. This is necessary to properly configure the router and do any router firmware updates.
Then try the router's address in the browser's address bar and see what happens, be sure to use the address and such as recommended in the router's user guide.
