Router Lights Meaning: What Each Light Tells You
What each router light means, from power and internet to WiFi and WPS, plus what to do when a light is red, orange or off.
The lights on the front of your router are a quick health check. A solid green or white internet light usually means all is well, while red, orange or a light that is off points to a specific problem.
Each router light shows the status of one part of your router. A solid green or white light usually means that part is working normally, while a red, orange, or off light usually points to a specific problem.
Brands use different colors and icons, but the meaning is very similar across TP-Link, Netgear, Linksys, ASUS, Huawei and ISP routers. Find your light below, then follow the fix.
Router lights at a glance
| Light | Normal state | Problem sign |
|---|---|---|
| Power | Solid green or white | Off, red, or blinking for a long time |
| Internet / WAN | Solid green, white or blue | Red, orange, or off |
| WiFi 2.4 GHz / 5 GHz | On or blinking | Off when WiFi should be on |
| LAN / Ethernet | On or blinking for each connected port | Off when a cable is plugged in |
| WPS | Usually off | Blinking for a long time |
| DSL / Fiber / PON | Solid | Blinking for minutes, or red LOS |
When every light looks wrong, I start at the Power row and work down.
Power light
- Solid green or white: the router is on and has started.
- Blinking: it is starting up or updating firmware. Wait a few minutes and do not unplug it.
- Red or orange: a startup or hardware problem on many models. Restart it.
- Off: no power. Check the adapter, the socket and the power button.
My first check is always the power light, before I touch anything else.
Internet light is red, orange or off
This is the most common problem. It means the router cannot reach your internet provider. I restart the modem first, since the router alone rarely fixes a red light.
- Restart in order: turn off the modem and router, wait 30 seconds, start the modem first, then the router.
- Check the cable: the WAN or Internet port must connect to the modem or wall socket.
- Check for an outage: look at your ISP status page or app on mobile data.
- Login details: PPPoE connections need the username and password from your ISP. A reset erases them.
- Still red: call your provider. The line or account may need attention.
WiFi lights
- On or blinking: WiFi is broadcasting. Blinking shows data moving.
- Off: WiFi is turned off by a button, a schedule or the admin settings.
- Only one band lit: the 2.4 GHz or 5 GHz band is turned off. Turn it on in the WiFi settings.
Slow even when the light is on? See our guide to boost WiFi signal and speed. For me, the off-by-schedule setting is the cause I check first when WiFi goes dark.
LAN, DSL, fiber and WPS lights
- LAN lights: one per port. On means a device is connected, blinking means traffic. Off with a cable plugged in suggests a bad cable or port.
- DSL light: solid means the line is synced. Constant blinking means the router cannot sync with the phone line.
- Fiber, PON or LOS light: PON solid is good. A red LOS light means the fiber signal is lost. Check that the fiber cable is not bent, then call your ISP.
- WPS light: blinks for up to two minutes while pairing. Steady blinking or red means pairing failed. Try again or connect with the password.
When a fiber light turns red, I check the cable bend before I call the ISP.
Light colors by popular brand
| Brand | Good internet | Problem |
|---|---|---|
| TP-Link | Green or white internet icon | Orange internet icon |
| Netgear | White or green Internet LED | Amber Internet LED |
| Linksys | White or blue logo | Amber or red logo |
| ASUS | White or blue WAN | Red WAN |
| Xfinity gateway | Solid white | Blinking amber or orange |
| Huawei | Solid green or blue | Red or off LOS / internet |
Colors vary by model, so check the quick start guide if a color does not match. I keep the brand table handy, since the same colour means different things by brand.
When to reset or replace the router
- All lights blink together for a long time: the firmware may be stuck. Restart, then try a factory reset.
- Only the power light is on after several restarts: the router may be faulty.
- Lights normal but no internet: see WiFi connected but no internet.
A reset erases your settings, so follow our router reset guide and keep your ISP login handy. For me, a router that only shows its power light is already past its best.
Frequently Asked Questions
What does a red light on my router mean?
On most routers a red or orange internet light means there is no connection to your internet provider. Restart the modem and router, then check for an outage.
Why is my router blinking?
Blinking usually means activity or startup. A light that blinks for many minutes, especially power, DSL or WPS, points to a problem.
Should all router lights be on?
Not always. WPS is usually off, and LAN lights are only on for ports with a device connected.
What does an orange internet light mean on TP-Link?
The router is on but has no internet. Check the cable to the modem, restart both devices and confirm your ISP login.
Why is the WiFi light off?
WiFi may be turned off with a button or schedule, or disabled in the settings. Turn it back on in the admin page.
