We have AP CW9166I Microsoft DHCP not working

Our access points have stopped giving DHCP addresses to clients. They were working for about 2 weeks and stopped.

How is the configuration of the switch port where the AP is connected? Please provide us with more details, such as your topology.

Thanks

It seems to be ok. Have you checked if there are still available IP addresses on your DHCP server?

If nothing has changed on the network side, IP address exhaustion may be the reason.

Yes, I've been looking at the Windows DHCP server. We should have plenty of licenses. The scope is from .70 to .180.

Can you share a screenshot of how many free addresses you still have on the server? Please.

I would also like to know who is the gateway of your network (Switch Core) and if the IP Helper-address is configured on the Core interface?

I don't know how to find that.
