Arris / blinking blue
Arris blinking blue light
On Arris SURFboard modem or gateway hardware, a blinking blue light often means pairing, WPS, firmware work, or a higher-speed channel trying to lock. Arris modems often expose upstream and downstream signal separately, which helps separate coax signal problems from Wi-Fi problems.

Safe order
Check in this order
- If WPS was pressed, let the pairing window close.
- Check whether the online light is steady.
- Avoid repeated resets during firmware or boot activity.
- If the light keeps blinking, power cycle once and retest.
Light labels
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.
