hotspot DHCP deassigned/assigned, lost DHCP lease

Sun May 23, 2021 6:34 pm

Hello,
I've got a big problem with my MikroTik RB4011iGS+ HotSpot solution:
  • MikroTik LOG: every few minutes dhcp1 deassigned IP from MAC and then dhcp1 assigned IP to MAC
  • Wi-Fi hotspot client: sometimes it takes quite some time to get an IP from DHCP Server
  • Wi-Fi hotspot client: while roaming to another access point hotspot user will be logged out (lost DHCP lease)
  • Wi-Fi hotspot client: sometimes after a few minutes and sometimes after a few hours hotspot user were logged out (maybe lost DHCP lease, too)
Where is the problem and how to solve it? Please ask me if I should add some more information about my network devices or some other config values.
