This light is often labeled as Online, Cable, Sync or Signal and usually has a symbol similar to the internet light on a router as mentioned above. Similar to routers, most modems (both Cable and DSL) have a light dedicated to the broadband connection. If the cable is all fine, then it's time to check your cable or DSL modem's light. But if it's off or red in color, then it's time to check to make sure that the network cable that connects the router's WAN (Internet) port (often on the back of the router) to the modem is plugged in securely and not broken in any way. In most cases, this light needs to be lit solid (white, green or amber) or flashing to show that internet activity is happening. This light is often labeled as Internet, WAN, or marked with a symbol of globe or a satellite flying around a globe. Most routers have a single light dedicated solely to the status of the internet connection. When you lose the internet, here's how you can use some of them to troubleshoot the problem. What isn't obvious is what the hell the purpose of these lights is. Actually, I was being facetious saying "you may have noticed" because these lights are totally obvious.
