There is a zoo of devices, namely: UniFI WiFi, Kerio and Server 2019 with deployed AD, DNS and DHCP.

The DHCP function is fully transferred to the server, the Kerio forwarder is specified in the DNS. Everything seems to work, but sometimes the following happens - the IP address is issued, LAN and the Internet do not work. The problem disappears after just 5 reconnect to WiFi, while the IP remains the same. To be honest, I don't understand how this problem works. There are no errors anywhere. It started 100% after deploying the server.

what does the term "LAN and internet not working" mean? what do ping, tracert and nslookup say for external and internal resources (the first two by name and by address)? time of issue of the address on DHCP coincides with problem time? if the clients wireless WiFi analyzer watched?
