Hi

IP reservation already configured for each device with MAC address, everything was ok, suddenly DHCP server starts to assign wrong IP address for some devices. 

Also, some bandwidth rules became ineffective and the devices get the maximum speed.

The problem that I have authorization rules that will be lost if I restarted the router so more than 100 devices needs to login again. 

So, any help to fix these issues without restarting the router or reset it?

Thanks
