comment What does this mean?192.168.2.2 in use by d8:a2:5e:41:aa:6e, DHCP Server 192.168.2.1
It's not necessarily a misconfigured DHCP server. If there are devices on the network using manually-configured IP's, that would also cause a conflict. In that case the solution is usually to just use DHCP for everything.
