DHCP Assigned and Deassigned

Wed Feb 09, 2011 5:00 pm

can someone help me figure out why this is happening...

i am getting messages in the log like:

dhcp1 deassigned 192.168.99.9 from <MAC ADDRESS>
dhcp1 assigned 192.168.99.9 from <MAC ADDRESS>

and so on...

why is this happening and how to fix it?

this is on a RB600 with RouterOS 4.16

Thanks

Hello guys.
Solution is this. Disable the DHCP pool of the hotspot server.

ie Go to ip-hotspot-servers.
Select the hotspot server u are using and change address pool to none.
This way u have only one dhcp server working.

Had similar problem once.

That is the Universal 1:1 NAT pool, not a DHCP server.
Specific answers require specific questions. When in doubt, post the output of "/ip address print detail", "/ip route print detail", "/interface print detail", "/ip firewall export", and an accurate network diagram.

Hello!

I didn't want to start new topic, found this one. Anything changed? I see it on v30.1 Very annoying, any reason why this might be happening?

I have some additional info. Those devices is WiFi clients. WiFi served by UniFi device connected to Mikrotik. But Unifi doesn't do any DHCP, so I wonder..

I had the same problem with Mikrotik RB951G with Wi-Fi clients. The reason was a short "Lease Time" in DHCP Server settings. IP - DHCP Server - DHCP - Lease Time, I set 1d 00:00:00. Since, ther were no problem.
