Before troubleshooting, please ensure the Deco units are using the latest firmware version. If not, click here to update.

Main Deco has lost internet access.

  • Check the connection to your ISP’s modem.

Disconnect the main Deco from the modem, and then connect a computer to the same Ethernet port on the modem with the same Ethernet cable. Check if the internet is available on the computer.

If the computer has no internet access when connected to your modem directly, please contact your ISP or modem for support.

  • Check the LED status on the main Deco.

If the main Deco has a red LED, please refer to the link for troubleshooting.

Satellite Deco has lost internet access.

  • Verify which Deco unit(s) is affected and what the light status is.

Please distinguish solid red or flashing red, and record the MAC addresses of the Deco units, which have dropping issue.

If the satellite Deco has a flashing red LED, please refer to the link for troubleshooting.

  • Check for interference or obstructions.

Satellite units should be placed in an open unobstructed area.

  • Use the Deco app to determine the signal strength of your satellite unit(s)

Deco units with a poor signal should be relocated closer to the Main unit. We recommend 25-30 feet between units.

  • Remove any Switch (if applicable) from the network

If you are using a switch between Deco, remove it and see if the connect stabilizes

LED status on all Deco units is solid white or green but certain wireless devices drop out or lose internet suddenly.

Certain wireless clients drop out or lose internet suddenly

  • Update the driver of the client's network adapter.
  • Identify the issue, such as Wi-Fi still showing connected but no internet access or unable to connect to Deco Wi-Fi anymore when the problem happens.

If Wi-Fi is still connected but has no internet access, please try moving the client near one of the Deco units and reconnect the Wi-Fi to see if the internet works. (Disable Wi-Fi and enable it on the client device)

If the client device is unable to connect to the Wi-Fi, you could refer to the link for troubleshooting.

  • Check if the client is included in the Blacklist or a profile under Parental Control, which is paused or at bedtime.

Certain wired clients drop out or lose internet suddenly

  • Update the driver of the client's network adapter.
  • Change the Ethernet cable between the Deco and the client.
  • Change the port on the Deco or the wired client.
  • Connect the client to a different Deco for comparison.
  • Connect the client to a Deco

LED status on all Deco units are solid white or green, but all client devices drop out randomly

If all client devices are connected to Deco Wi-Fi but no Internet access, refer to the link for troubleshooting.

If all client devices fail to connect to Deco Wi-Fi, refer to the link for troubleshooting.
