Model: Deco S4  
Hardware Version:
Firmware Version:

I have 3 x Deco S4, one is the master, one is connected via WiFi and one should be connected via the Ethernet backhaul. the ethernet cable runs from the master to a TP-Link switch where among others a smart TV and Apple TV are connected. They all work fine but when I connect the the third Deco S4 the whole network goes down, including the the second Deco connected via WiFi (all Deco's go RED)

What could be the problem?

Hi, is the network layout like this:

5213307d3dda479791b7c6c0e1dd508a

May I know the model number of your TP switch?

And when unplugging satellite S4-2 from the switch, will the other two units recover gradually?

Thank you very much.

Best regards.

  @David-TP The switch is a TL-SG1008D Gigabit 8 port switch

The DECO S4 is hardware V2.0, Firmware Vsn 1.4.3, Build 20200918, Rel 77820

When I disconnect the ethernet back haul the system does recover

Thanks for the update.

the latest firmware for Deco S4 is 1.5.1 now.

It is suggested to update the firmware to be the latest version first:
