Quick answer
Router lights answer four questions: is the router powered and finished booting, does it have an internet connection from your provider, is data moving on your local network, and what are the wireless radios doing. Every brand uses those same four indicator families.
What is not universal is the colour. TP-Link uses green for a healthy power state, Netgear uses solid amber while starting and solid white when ready, and eero uses solid white for online. So the safe method is to identify the light by its label or icon, then read whether it is solid, blinking or off — colour comes last.
The four indicator families
| Indicator | What it reports | Typical states |
|---|---|---|
| Power / system | Whether the router has power and has finished starting | Solid = running; blinking = starting, resetting or upgrading firmware |
| Internet / WAN | Whether the router holds a connection from your provider | Solid = connected; off or red = no internet or bridge mode |
| LAN / Ethernet | Whether a wired device is attached and whether traffic is flowing | Solid = attached but idle; flashing = traffic |
| Wireless / WPS | Whether the Wi-Fi radios are enabled, and the WPS pairing state | Off = radio disabled; flashing = activity or pairing; solid = pairing complete |
The same healthy state looks different per brand
| Brand | “Everything is fine” looks like |
|---|---|
| TP-Link (Archer and similar) | Power solid green; Internet LED green; WLAN solid or flashing green while in use |
| Netgear / Nighthawk | Power solid white (solid amber means it is still starting); Internet light solid when connected |
| eero mesh | A single LED solid white. Solid red means offline, flashing red means resetting |
| Motorola cable modems | Power on, Downstream and Upstream solid, Online solid green — green for one channel, blue for several |
Read the pattern before the colour. In every manufacturer’s table, blinking means “working on it” and solid means “finished”. A light that is still blinking is usually not a broken light.
How to identify your own router’s lights
- Find the model number on the label underneath or behind the router, then look up that model’s own light table. Colours differ between generations of the same brand, so the model matters more than the brand.
- Match the icon or label, not the position. Labels such as Internet, WAN, Online, WLAN, 2.4G, 5G, WPS and LAN tell you which family you are looking at.
- Note the state: solid, blinking or off — and how long it has been that way. A modem or router that has just been power-cycled can blink for many minutes while it trains and registers.
- Check the manufacturer’s app as well as the LEDs. Apps from eero, TP-Link and others report an outage reason that the light alone cannot express.
- Treat one light on its own with care. A single green light in the middle of a cycle means far less than the combination of Power, Internet and LAN states together.
A red or dark internet light
That state means the router has no connection from the provider side. Start at the modem or ONT and the cable, not at the router’s settings.
A flashing power light that never settles
On most brands, a power LED that keeps blinking means the device is starting, resetting or updating firmware. Give it several minutes; if it never settles, the next step is a reset.
Brand-by-brand light references
Every one of these pages follows the same method: the manufacturer’s published states, what each one calls for, and a diagram of the indicator set.
- TP-Link router lights · TP-Link orange light · TP-Link red light · TP-Link Deco lights · TP-Link extender lights
- Netgear router lights · Netgear orange/amber · Netgear red · Orbi pink · Orbi blue · Orbi purple · Orbi flashing white
- eero light colors · eero red light · eero white light but no internet
- Motorola modem lights · Arris modem lights · US/DS light blinking
- Xfinity modem lights · Spectrum modem lights · Verizon router lights · CenturyLink modem lights · Cox Panoramic lights
The short version: name the light from its label, check whether it is solid, blinking or off, and only then consider the colour. Solid generally means finished; blinking means still working. For the exact meaning, use your own model’s table — the pages linked above are organised that way.

- NETGEAR, What are the LEDs and ports on the front panel of my Nighthawk router called? — solid amber for starting, solid white for ready.
