[Dnsmasq-discuss] New leases constantly issued for same client

[Lagarto]

Hello,

I am running OpenWrt in an Atheros 9342 AP and using dnsmasq(2.62) as
dhcp server.

When there are a few (~10) clients connected, everything works fine.
However, when there are more clients, something starts to happen: one
or more clients will keep requesting for a new lease, instead of
keeping the one previously assigned.

Any idea why this could be happening? If the connection is dropped,
wouldn't it be expected for the client to get/renew the previously
assigned lease?
Thanks in advance.

Regards,
-Leo Martinez
