Model: Deco
Hardware Version:
Firmware Version:

This Article Applies to:

All Deco models

 

Typical problem description:

1. Main Deco turned red after creating the Wi-Fi name and password during the setup;

2. Main Deco went solid red after working normally for a long time, rebooting could not get back to green/white.

 

Possible Reasons and Suggestions:

Case One: the red light is during the setup.

The following issues might cause this problem:

1. The selected internet connection type (Dynamic IP, PPPoE, or something else) is not right, or whether the internet VLAN ID is needed.

----Please confirm with the ISP first whether you have got the correct internet configuration details.

2. The current DNS server failed to detect the internet service; if it was the case, you would get a valid IPv4 address under Deco APP > More > Advanced > IPV4, but no internet.

----Please refer to this link to change the DNS server to be 8.8.8.8/8.8.4.4.

3. The internet service provider might require IP &MAC authentication (very common in cable modem from Charter/ (Xfinity)Comcast/ Cox), such as

My ISP needs MAC address authentication to get internet service

Here is what you can do:

----Power off the modem for about 3-5 mins (or remove the coaxial cable from the modem).

----If still the same, please connect the Deco like ISP modem --- Deco ---<Ethernet cable> --- laptop, and refer to this link to do the mac clone.

 

Case Two: Deco suddenly went to red after working fine for a long time.

1.Please go to Deco APP>More>Advanced>IPV4. if the IP address is blank, please unplug the cable between modem and main Deco, connect a computer to the modem and make sure the ISP modem is working properly.

---while if there is an IP address, please refer to this link to change the DNS server to be 8.8.8.8/8.8.4.4 as well.

2. then put the cable back to Deco, if the LED is still red and no IP, please email us with the following information:  

  • The service provider and model number of ISP fiber/cable modem;
  • A picture of the IPv4 settings on the Deco APP;
  • A picture of the IP settings (IP and subnet, gateway/DNS server) on the PC when it is connected to the ISP modem-How to find IP address on your devices?

 

 

Case Three: Deco will randomly turn red during the day.

If it is the case, the Deco might experience a unstable connection. And please refer to the following link for more suggestions:

Hi, 

Have you tried to hold the reset pinhole for 1s to factory reset it once and add it back to the previous mesh network?

If there is no change in the LED status, it is also suggested to refer to this lin to run a firmware recovery on the Deco:

How to use firmware recovery if the Deco become brick

 

Thank you very much.

Best regards.

What if I have a similar case with my deco x20-dsl and have the latest firmware available in my region? What does it mean deco becomes a brick?
