DHCP: offering lease <ip address> for <mac address> without success.

RouterOS General
1

Hi,

a strange behaviour.
Simple network:

  • DHCP server
  • hotspot
  • ubiquiti unifi antennas
  • vlan (two SSID, two VLAN)

When wireless clients increase I get a lot of: wifi offering lease for without success.

I have already tried in DHCP server “always broadcast” and “authoritative=Yes”.

MTU in mikrotik is 1500.

Any ideas?

I’m seeing a very similar issue
My routerboard offers the IP to the unifi AP but it’s never bound.

Do you have a switch in between the AP and DHCP server?
