We are using the Cisco Airespace 1020 with a 4136 WLC. We get the AP's to talk to the controller as long as they are on the same segment. If I place AP on different Subnet then it can not find the controller. We are using a Microsoft DHCP server and do not know what services to push down with the DHCP scope. Believe it is 43 and 60 but unable to get that to work. Does anyone know how to configure those services on a scope with the Microsoft DHCP server.
