• Your Deco has lost internet or is unable to connect to the main Deco if the red light is flashing.

• Verify that your network or internet modem is up and running.

• Verify that Ethernet cables are securely fastened and in good condition.

• To restore the signal, move the satellite Deco units closer to the main unit.

• Make sure every Deco gadget is turned on.

• In that order, restart the Deco devices, router, and modem.

• After a minute, unplug the Deco and re-plug it if the red light continues.

• Check to see if your ISP employs MAC address binding, and if so, reset the modem.

• If not properly set, do not switch between the router and access-point modes.

• Instead of using a different router, try connecting the main Deco straight to the modem.

• Make that the LAN-to-LAN connections are correct for wired backhaul configurations.

• To check the network status of Deco, visit tplinkdeco.net or utilize the app.

• Update the Deco firmware to address any potential issues.

• If every Deco blinking red light, the main unit probably doesn't have internet, so concentrate your debugging efforts there.
