Tags: #Deco Ethernet Backhaul
Model: Deco X55  
Hardware Version: V1
Firmware Version: 1.7.1 build 250806 rel 70421

My setup is as this:

 

1. movistar rounter as 192.168.0.1

2. connected to TP link router ER7206

3. single connection to a TP-Switch as TL-SG108S V4 as supporting the mesh protocol and with loop detection ON

4. TL-SG108S connected my Ethernet X55 Master as Backhaul

5. TL-SG108S connected my Ethernet X55 Second as Backhaul

 

The TL-SG108S V4 switch detects a loopback O:((

 

as soon I change, Second X55 reboots and restart the TP-Link switch to get out of loopback detections

 

5. TL-SG108S connected my Ethernet X55 Second as Wifi connection no Loopback detections!!

 

a) Also it looks like this, as soon the second X55 looses any Ethernet connections, the X55 boots ... and is dead for may up to a minute. This is not a immediate mesh support!

b) In addition the ER7206 switch  seams not to support Backhaul protocol.

Hi, thank you very much for the feedback.

Please make sure Deco X55 is set to "Access Point" mode:How to set up Deco to work in Access Point mode

 

It is also suggested to refer to:

General questions about Ethernet Backhaul feature on your Deco

Q5

In the early stage of Deco Ethernet Backhaul, there is a short network loop for 1~2s, as during this period,  both WiFi Backhaul and the Ethernet Connection are active.

Thanks a lot.

Best regards.

Well, the issue with the X55 is as this:

 

1) TP-Link X55 officially do not support backhaul drawing 3!

 

2) while my setup is given from a centralized TP-Switch connected above and downstairs with an ethernet wire and connected to a TP-switch. While no direct WifI connections possible.

 

3) Downstairs as with several PC's connected to an additional switch.

 

4) in other words, as X55 to work properlay as using backhaul, reguires chained by X55 Switch operations. This will only operate as soon X55 is up and running. While some runs on UPS for alarming purposes.

 

5) will look for a WifI system where backhaul do not require chained ethernet connections.

 

anyway, it looks as using all X55 from a centralied TP-Link Switch (who supports backhaul protocol) is working ... but not supported and may not tested & supported
