Alan,
Not familiar with WAP, but before connecting it to the network you may need to configure it as standalone first. Connect it to your laptop and give it an IP in the same range that is in the instruction. Once you are in, than you can deploy the IP, DNS, DHCP, username, password, etc..... then connect it to the network
