Just to share an observation from my end after a few days and looking at the logs - it seems AiMesh takes very well care on moving clients from node to node and roaming assist seems to act more like a safety belt, to hardly drop the connection of clients. I have no hard facts nor confirmation on this I can underline with some log entries, therefore it is just an observation. How about yours ?
Similar. I've had a couple one-off issues with clients "sticking" more that i would like, but i believe it's more cause by the AX86U's improved coverage of my space (i.e. i don't even need a node there anymore). Need to test more though.
