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.
Only factory-reset after signal pathways and wires have been checked.
During initial setup, keep Deco units within 10 to 15 feet.
LEDs should become steady white or green once they are stabilized.
Contact assistance if, after all procedures, there is persistent red blinking, which might indicate a hardware breakdown.
