Which Android tablet is this and which version of Android?

hostapd does not have functionality to refuse another connection after
a new association.

Would you be able to provide debug logs from hostapd (e.g., -dt on the
command line) showing the initial connection and reconnection attempts
after the table reboot? It would also be interesting to see logcat
information from the tablet with Wi-Fi debugging enabled to show what
happens there after that reboot and how it recovers from this in 5-8
minutes).
