Model: Deco X20  
Hardware Version:
Firmware Version: 1.1.3 Build 20211103

Hi,

 

I have the X20 and wanted to try to ethernet backhaul them as the speeds I am getting from the other decos are not even 50% of my internet speed.

 

Setup: 3 floors - 1 Deco per floor. Main deco is in 2nd floor -> backhaul to 1st and 3rd floor.

 

When checking the deco app it is saying that the source from the 1st and 3rd floor is still the 2nd floor WiFi instead of ethernet. 

 

I have checked the ethernet cables and they are working fine with my laptop directly connected to it. Running at 300mbps for both cables so I know it is not the cables.

 

I tried switching ports on the deco but it will still not use the ethernet as the source. Rebooted the deco, restarted the network, both did not work.

 

Network: ISP -> Switch -> Deco

 

I am using Tp-Link LS1005G 5-Port 10/100/1000Mbps Desktop Switch


My question is, does my ethernet backhaul setup correct or do i need to directly connect the 1st and 3rd deco to the 2nd deco's ethernet ports?

 

If my setup is correct how can I force the 2 slave deco to use ethernet backhaul?

Check this FAQ: General questions about Ethernet Backhaul feature on your Deco

 

If your setup matches this picture from the document that I copied below, you will need to change your Deco mesh to Access Point mode, to force Ethernet backhaul. See How to set up Deco to work in Access Point mode.

 

This, or just wire Deco X20 differently, according to the FAQ.

Can I ask what is the pros and cons of going Access Point on my deco?

  @Alexandre. 

 

I set my mesh to Access point and now my speed is at 50mbps compared to the 150mbps before? Any ideas?

 

Thanks!

Hi, May I know how you ran the speedtest, via Wi-Fi or Ethernet connection from Deco?

Please also make sure it is connected to 5Ghz.

The speed under Access point mode should be as good as wireless router mode.

Best regards.

I ran the tests both from the Deco App and fast(dot)com which gave the same results. 

 

I have all three decos wired via the ethernet and under wireless router mode.

 

I do not have the 2.5 and 5ghz bandwidth separate.
