Netgear / solid red

Netgear solid red light

On Netgear router or cable modem hardware, a solid red light usually means the device is not online, cannot authenticate, or has a serious link problem. Netgear models often separate Internet, Wi-Fi bands, and Ethernet, so one bad LED can point to a cable, WAN, or local device issue.

Before a factory reset

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.
