1 The MAP sends DHCP Discover message from the MAP's port 1.
2 The DHCP server replies with a DHCP Offer message containing an IP
address for the MAP, the default router IP address for the MAP's IP
subnet, the DNS server address, and the domain name. MAP then sends a
DHCP Request message to the server and receives an Ack from the server.
3 The MAP sends a broadcast Find WX message to the IP subnet broadcast
address.
4 When the MAP is unable to locate a WX on the subnet it is connected to,
the MAP then sends a DNS request for 3com.example.com and
wlan.example.com.
