People are just realizing what the flashing lights on your WiFi router mean – and two should never be ignored | The Sun

FEW people know what each light on their router means — but you might be missing out on a warning sign.

But experts warn that adopting an ignorance-is-bliss mindset to your Wifi router could mean you're missing out on vital warning signs.

Network expert Theodore Covey shared with Networks Hardware his troubleshooting guide for what each of these lights mean.

Your router has a range of light colors: white, amber, yellow, and green, each color determine your router’s status.

We break down what both the bad and good colors mean below.


Red lights means something is wrong, warranting urgent attention.

"If you see blinking red lights, you’re having trouble connecting to your network," says Covey, whereas "solid lights indicate there’s an error with your connection."


Amber lights have various possible meanings.

"If you see a solid amber light on a Linksys router, that means you have issues with your router due to configuration options," says Covey.

But, if you see it on a TP-Link router, you only need a firmware update — firmware is a computer program that is "embedded" in a hardware device and is an essential part of the hardware.

On certain routers, blinking white LEDs can mean your router is failing to connect to your modem, or your router has corrupted firmware.

But it's not all bad: In other routers, white lights serve the same purpose as green LEDs.


Green lights show that everything on your router is fine.

"It shows that you have a powered on router and it’s delivering signals through various means—like Ethernet or Wi-Fi," says Covey.
