What the nearby label changes
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.
