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.

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.

I have the same problem with my MiBox S
it's spamming through logs and there is nothing I can do about it

for the moment I found 4 possible solutions (none of them helped me):
  1. disable loop protect on a port
  2. disable auto negotiation on a port and indicate correct fixed speed
  3. disable loop protect and auto negotiation
  4. check network mask

Check if Detect Interface List is configured to none. When this wasn't in that option, like for example "all", the mikrotik sometimes recognized my WAN port as a LAN port and the other way around too.

I'm using RouterOS version 6.49.7.
This is a solution that works for me:
