Hello from Perú. DHCP is enabled on my router ER7206

Some clients take too much time to obtain an ip address

I have two vlans, each with it's own range of ip addresses

The system log show various messages from these clients "DHCP Server received DHCP Decline from client ..."

Is there DHCP like this in ER7206 V2?:
