Thank you for the update, I am glad works for you

When walking to some corner meeting rooms (but still has good
wifi connectivity, verified by another Android phone wifi ;),
the roaming may be from previous AP to none and none to next AP,
the process may need 1 to 2 minutes to be stable again, it's not
ideally swift but acceptable,

Yes, I know we have more works to do on roaming, it is on our to-do list

Thanks
Wey
