Hello @hockey , Please be informed that this issue occurs when the MR device is not able to receive an ARP response from the configured gateway IP address. In order to maintain the dashboard connectivity the MR would have failed back to the DHCP, however, the device will be still sending ARP requests to your default gateway IP address. So, I would suggest verifying the VLAN tagging on the management interface as well as the switch port to which the AP is connected.  https://documentation.meraki.com/MR/Client_Addressing_and_Bridging/VLAN_Tagging_on_MR_Access_Points ...
