Anyway to release dhcp leases

[tdub42]

Hey guys I have modified my dhcp lease range so that I can setup a lab. But some of my older items are connecting outside the dhcp range. Is there an easy way to make them change without making them all static. I have tried unplugging devices (nest) and rebooting router as well. Even leaving disconnected (by unplugging) for over 2 hrs. Any suggestion would be greatly appreciated.

Under Windows try issuing "ipconfig /release" then "ipconfig /renew". If it still fails, then turn off the router, reboot the clients, then turn the router on last.

Sorry I didn't add this the info problem are internet devices mainly hue, nest, etc. Any PC/Server OS no problem.

The DHCP server (the router in this case) can't force the behaviour of the client device. The client will typically ask for the same IP address that it previously had. If you have configured the DHCP server correctly you should be able to see in the logs that it refuses that request and offers a different IP address within the new range. It is then up to the client to accept this offer.

If the client isn't behaving in this way (or it's not even asking for an IP address) then it's a problem with the client, not the router.
