Model: Deco X20  
Hardware Version: V1
Firmware Version: 1.5.0 20210121 rel. 54794

I have two Deco X20 and borrowed M4R and M3W to test a third Deco with X20s.

 

Unfortunately there is a problem with roaming between WiFi 6 and WiFi 5 using Galaxy S21. When the phone connects to X20, it does not roam to M4 even if the WiFi signal is very weak, when I disable WiFi in the phone and it connects to M4, it is the opposite - roaming does not work to X20, the phone is connected all the time to M4.

 

This is not a Samsung fault because I have tested also X20s with M3W and roaming between them is perfect besides different WiFi standard. I have also tried to reset 3 times M4R and connect again, it did not help.

 

Is it anything I can do, or I need to buy another Deco?

For AP steering among different Deco nodes, only when the signal strength of the current AP (Deco) becomes lower than a threshold and the signal strength of another AP is good enough, Deco will recommend clients to roam via 802.11k/v standards.

 

For your case, it is a little bit different, Except for the Galaxy S21, did other devices behave the same?

@TP-Link

Devices without 802.11ax roam OK, I have also Samsung S21+ and Tab S7 - problem also exist, but those are similar devices. I will try on a Lenovo T14 (also 802.11ax) but I need to connect M4 again.

 

I understand that between 802.11ax and older standards roaming can be difficult, however with X20 and M3W it works flawlessly, so why shouldn't it with X20 and M4?

@TP-Link

I have tested Lenovo T14 with 802.11ax and it is roaming properly between X20 and M4. It looks like, it's a Samsung problem. Do you have any ideas what could I do?

Hi, it is suggested you could turn off the Mesh Technology on the Deco APP for Samsung S21+ and Tab S7.

Turning off the Mesh Technology on the Samsung devices would not interfere with other mobile devices.

And if you have enabled the private MAC address, you could also turn it off to test the connection.
