It looks like the one pictured in this article. Make sure this cable is plugged in securely, and both the link and activity lights are on. If you connect via a wireless card or wireless laptop, verify that either the wireless switch is on or a wireless network is selected. You may attempt to connect to the Internet after following any step listed here.

After checking to make sure your cable is plugged in and you find everything is secure but your internet connection is still not active, you may need to power cycle your modem or router. To do this, unplug the modem and/or router for 10 seconds then plug it back in.
