Hello @ramzik99 

Basically, whether to do Wifi roaming or when is a behavior of the Wifi network client device itself, please check QA here that could help explain the situation: 

Q11. Why the Wi-Fi device is not always connected to AP with the strongest Wi-Fi signal or nearest AP in a OneMesh network?

You could also test a different mobile network in Wi-Fi roaming, like IOS mobile device which could do better in Wifi roaming.

To see if it is related to WPA3, you could set router to WPA/WPA2-AES encryption, factory reset the extender and reinstall it, when router use WPA2 encryption, could the network device do Wi-Fi roaming like before?  If still the same, Can I know what the model device that is inclined to connect to Wifi of router? 

Hello   @ramzik99 

Thank you for the reply, glad to may I know what mobile device did you test, and it's Android or IOS version?  

To see if it related to certain network client behavior, you could also test a different device, like an IOS device if you got one.

Make sure OneMesh & Smart Connect are Enabled. 

If still the same, to look into that further, can you help  you record the videos of roaming when use WPA2/ WPA3 separately on router when walk from place A to place B (same locations), and share the photos of security settings on router at that time, thank you. 

Hello  @ramzik99 

Thank you for doing more test.  To see what happened clearly, can you help take the videos showing the Wi-Fi roaming status? For example, when router is on WPA2, test roaming from Locate A to Location B and help take a video; Then set to WPA3 do the same test and help get the video. 

It is recommended to also test a different mobile device like IOS device if you got one. 

May I know the model of mobile device that you have tested and its OS? And can you share the photo of router security settings and router firmware. Thank you.
