TP-Link Deco router lights: what each colour means, by model

TP-Link’s Deco mesh units have one light, and TP-Link’s own page gives a table per model group: most Deco models (the X, XE and BE series) are green when all is well, the Deco M4, E4 and W2400 are white, and the older M5, P7 and M9 Plus have no pulsing states apart from blue. The Deco M3W extender uses separate power, signal and band lights and is not included here.

What is not here

  • TP-Link Archer routers — TP-Link’s own Archer light FAQ (‘What should I do if the LED of TP-Link router is abnormal?’, updated 2023-03-17) gives troubleshooting steps for a light that is off, but no table of what each colour means; it sends each model to its own Quick Installation Guide, and Archer lights differ by model. No Archer page until those guides are read model by model. www.tp-link.com Checked 2026-09-29.
