Model: Deco X60  
Hardware Version: V3
Firmware Version: 1.3.0 Build 20240830 Rel. 50008

For some reason, Deco starts to slow down to the 80-90Mbit speed after a while. It happens not only with clients which are connected via WiFi, my laptop connection speed slows down. While this problems exists, I tested with Open Speed Test which runs on my Nas which is connected to the other Deco Unit which is connnected to my main Deco via Ethernet backhoul. I just only plug out all the ethernet ports on the main deco (coming from the modem and my laptop). Then it is resolved. I don't know if this happens because of QoS. I could not find anywhere to disable it. Because I know this problem was exist on my previous Deco M4. After I disabled it, speed problem was gone. I have the same problem again. I am not sure this problem occured after I update the firmware or not. 

I have tested via iperf3 which runs on my laptop and the openwrt router, It shows the slow speed and normal speed which can be resolved by plugging out of the ethernet cables coming to this main unit. Please fix this or make an option to disable QoS :)

Hi, Thank you very much for your time and patience.

 I think Deco X60_V3_1.3.0 does support turning off QOS.

-Can I have a screenshot of the QOS configuration page?

And if you can't disable it, you could set it to 1000/1000 Mbps download/upload and don't enable any "High Priority" devices.

 

By the way, is the Deco X60 working in wireless router mode?

Can I have a picture of your network topology?

- The speed loss is very likely due to the Ethernet connection speed of the main Deco suddenly dropping to 100mbps. So if there is a wired device(not the satellite Deco X60, but a network switch/printer/TV, etc.), please try to temporarily unplug it from the main Deco X60.

- It is also recommended to replace a new Ethernet cable to connect the main Deco X60 to the ISP modem.

 

Wait for your reply and best regards.
