We have a network with two VLANs associated with their own subnets. VLAN 1 is tied to SUBNET 1, and VLAN 2 is tied to SUBNET 2. We use subnet 2 in a second section of our building. The backbone is Cisco catalyst 3850, and the problem right now seems to be almost entirely happening with only WIFI users in the "subnet 2" area of the building, which are Cisco Meraki APs. While users have been getting IP addresses dynamically without issues for some months now, they suddenly are no longer able to get an address thru DHCP. If I statically assign the IP, it works. There are hard-wired desktops on the 2nd subnet that are working fine - those are DHCP, with 4-hour leases, incidentally. In the "SUBNET 1" area of the building, users are working fine on WIFI or LAN, without issues. Nothing that I know of has been changed on the netowkr - no work or anything like that has been done over the last week, when this started happening. Could this simply be a glitch with the Meraki APs or the AD server??
Thanks for your help
