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.
