I had this issue for months. None roamast entry in log, only the
roamast: ROAMING Start... And, of course, the feature doesn't work.
But now, after messing with nvram params without any result, I have discovered where is the issue (in my case).
Roaming Assistant doesn't work with Guest Networks. I deactivated and removed the configuration of my guest network, and Roaming Assistant is working again as expected. In logs, now there are roamast entries, like
determine candidate node,
disconnect weak signal strength station, etc.
I have 2x GT-AX6000 running Merlin 3006.102.7_2, but this issue is present along all 3006 IIRC. FYI, you can see all my configuration
here but I use the same SSID for 2.4 and 5GHz with Smart Connect.
It's curious, because if you select only one AP to use the Guest Network, Roaming Assistant works in the unselected node, of course without any real effect because there is not candidate nodes to move the client. To see logs from the node you must access via SSH and logs are in the file /jffs/syslog.log. You can see them in real time with the command: tail -f /jffs/syslog.log
Best regards.
