I've had a look and I don't see any issues with this debug.
The debug starts at "12:59:48.549" and by "12:59:48.583" the client got an IP address of "10.84.150.205".
Please expand, with more details, what issue(s) are observe when this happens?
Do the wireless clients get a yellow "!"? Did the wireless clients loose wireless network? Did the wireless clients lost access to a certain DB?

Hello @Leo Laohoo
Client experience high level packet drops. It can begin as unexpectedly as it ends.
without any kind of OS changes, on the hotspot from the phone at the same time, there are no problems.
