What I have is a 150+ apartment complex with a RB2011 running a hotspot. The system will run top-notch for 2-3 hours then stop handing out DHCP addresses. I have tweaked the config as much as I know how and even upgraded to V 6.10. The attached photo is what I was witnessing earlier in the log file.
After Googling this I read to set the hotspot's server DHCP pool to "none" and I did that. Then, I checked to make sure there was a DHCP server set-up and there was. It is associated with the same interface as my hotspot.

Any ideas or input?

Thanks in advance!

Please show an export of the IP>DHCP Server. The problem you might be having is the duration of the lease on your dhcp server. Until we see the configuration it is difficult to help.

There are reports in the 6.10 Thread (one from me) that dhcp does not work with vlans.
There is a bug. Consider downgrading.

My DHCP server lease time is set for 6 hours. I've read in the Wiki to make sure your DHCP server IP isn't in the scope of the DHCP pool you have set. I have my server sitting on the bridge-local interface as well as my hotspot server. Could this be posing a conflict? I'm new with MT so please bear with me when asking to run terminal commands.

Thanks in advance.
