No Internet Connection? How to Troubleshoot Internet Issues | HighSpeedInternet.com

Nearly all modems and routers have LED status lights. You may also have a combo unit that is an all-in-one modem/router (also called a gateway). Either way, the LED status lights on your equipment are very helpful for quickly diagnosing network problems.

Check the internet signal light

The light for an internet connection is on your modem and is usually labeled WAN, Internet, or with a globe icon, and you can tell the internet is on if the light (usually white or green) is solid.

If the light is red or not on at all, you have an internet signal problem as your modem isn’t successfully connecting to the internet. If this is you, skip ahead to our internet signal troubleshooting section.

Check the Wi-Fi light

The WiFi light(s) will be on your router or somewhere below the internet connection light if you have a modem/router combo unit. Labels for Wi-Fi lights vary but usually will read “2.4G” and “5G,” “WLAN,” or “Wireless.” These lights should be on and are usually blinking. If the Wi-Fi light(s) are off or red, your router isn’t broadcasting a signal. Skip to the Wi-Fi troubleshooting section to begin troubleshooting.

If the equipment lights aren’t revealing your internet issue, read on for the next steps.
