TP-Link AMARILLO-FIJO on mesh router: Deco stuck starting up
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
Solid yellow on a Deco means it is starting up. If it does not change within about two minutes, TP-Link recommends unplugging it and plugging it back in; if nothing changes, consider a reset with its button, knowing it erases the configuration.
Safety first
Stop and check this first
- Pressing the bottom button for one second resets the Deco to factory defaults and erases its configuration: you will need to set it up again in the app.
- For a warranty claim, TP-Link asks for the serial number from the Deco or its box and a photo of the invoice.
Safe checks you can perform
- Wait two minutes after powering on
- Unplug it and plug it back in
- Reset with the button and watch the LED
- If the reset does not respond

What it means
In TP-Link's official table, a solid yellow LED on a Deco (M5, P7, M9 Plus, M4, E4 and others) means the unit is starting up, and it normally changes within one or two minutes. If it stays that way, the Deco does not finish booting and never joins the mesh or provides Wi-Fi. TP-Link suggests waiting and rebooting first, then a reset; if it is still yellow after that, it treats it as a possible hardware fault. The LED alone never proves the Deco is faulty.
