Router Red or Amber Light: What It Usually Means
Identify the exact LED and blink pattern before restarting or factory resetting anything.

Amber often means startup, a physical link without internet, or an update; red more often indicates a critical device problem. Meanings vary by brand and model.
Checks to make in order
1
Identify the icon
Power, Internet, Wi-Fi, and Ethernet LEDs use colors differently.
2
Note solid versus blinking
A blinking update light is not handled like a solid fault light.
3
Check upstream service
Verify modem power, provider outage status, and the WAN cable.
4
Restart only when safe
Do not interrupt an update or reset; restart the modem first and router second.
Stop point
Stop and get help when
- The power adapter is unusually hot or damaged
- A critical red light remains after the documented recovery
- The router appears stuck in a firmware-update or recovery pattern
