Front-panel lights are a quick health check. Exact icons differ by brand, but patterns are similar.
Common LEDs
- Power: unit has electricity
- Internet / WAN: link to modem or ISP
- Wi-Fi: wireless radios on
- LAN: wired device activity
- WPS: pairing mode (disable WPS when idle)
If lights are off
- Confirm the outlet and power adapter.
- Try another outlet.
- Power cycle modem and router.
- If power LED stays dead, hardware or adapter failure is likely.
If internet light is red or off
Check the modem, coax/fiber cable, and ISP outage status. Admin WAN page tips: Wi-Fi connected but no internet.
