TP-Link Deco LED Red: How to Fix It

Q: Why is my TP-Link Deco LED red instead of blue?

A red LED indicates your Deco cannot detect an internet connection from your modem. This usually means there's an issue with the cable connection, modem, or ISP service preventing the WAN handshake from completing successfully.

Q: How long should I wait after restarting my Deco before it turns blue?

After powering on, your Deco should change from red to blue within 2-3 minutes if it can establish an internet connection. If it remains red after 5 minutes, there's likely a connection issue that needs troubleshooting.

Q: Can a bad Ethernet cable cause Deco red LED?

Yes, a damaged or faulty Ethernet cable between your modem and Deco is one of the most common causes of red LED status. Always test with a known working Cat5e or Cat6 cable to rule out cable issues.

Q: Will factory resetting my Deco fix the red LED issue?

Factory reset can resolve red LED issues caused by incorrect network settings or corrupted configuration. However, if the problem is with your modem, ISP connection, or cable, a factory reset won't help and you'll need to address the underlying connectivity issue first.

Abstract

When your TP-Link Deco shows a solid red LED, it means the device cannot detect an internet connection from your modem. This typically occurs due to a failed WAN handshake between your Deco and the modem, preventing internet access throughout your network.
