I have deleted all dhcp server leases as well as all hotspot users.
When they try to reconnect I've noted a strange thing : there are more hotspot user appeared with their own ip address than the active dhcp leases.......
Each hotspot user shouldn't get a dhcp lease before to become a part of hotspot system (so at least as many dhcp leases as hotspot users) ??
Or.. hotspot user has its own "dhcp method" or getting a lease some other way ??
