In the past with previous routers when it is unplugged or goes offline the client computers retain their IPs and are still able to function with a local server. With Mikrotik I’ve noticed that within seconds of unplugging the router they lose their IP and go to a private 169 address. How to I stop this from happening? If the router were to die I would like my customers to at least be able to use the functions of the server until we are able to get them up and running again. BTW my lease time on the router is 1 day currently and it is still happening.
You your server to get dhcp to client. Or yous from your switch or your acces points.

I want to use Mikrotik for the DHCP. I’m not worried about new computer requesting IP’s from the DHCP, I am only concerned about the computers that have already been issued an IP from the DHCP Pool. How do I stop them from losing their IP when their lease time is 1 day. They shouldn’t lose their IP after seconds when they still have a good portion of the day left on their lease time.
How can the users communicate if there is no power?
I assume that you suffer from power outages, and loose DHCP IP’s at the clients.
Are that laptop users? If yes, how is the switch powered?
If you suffer power outages, you should consider a UPS (good model with real sine wave), and connect the Mikrotik, switch and other active devices to the UPS.
If you have other problems (like people unplugging routers etc…) you should consider physical protection measures (like putting a lock to the server room, and keep the key to yourself).
