Short answer

Why is the Internet light blinking?

A short blink can be normal activity. A long startup blink usually means the router is trying to reach the modem or provider.

When the model is unknown, read the LEDs by function first: power, service, wireless, local network, and pairing.

Safe order

Check in this order

  1. Wait through a full startup cycle before unplugging anything.
  2. Tighten coax, fiber, or WAN cables at both ends.
  3. Check the provider outage page from mobile data.
  4. Restart modem first, then router if they are separate.

Before a factory reset

A reset can erase Wi-Fi names, passwords, port forwarding, and provider activation state. Use it only after power, cable, outage, and startup checks do not explain the light.

When to call support

Call the provider when Online, Internet, Broadband, US/DS, or Optical never reaches a steady normal state after one clean restart and cable check.

When Wi-Fi settings matter

Change Wi-Fi settings only when service lights are healthy but phones, laptops, or smart devices cannot join the wireless network.
