Chapter 3 Configuring the Access Point for the First Time

Protecting Your Wireless LAN

After you assign basic settings to your access point, you need to configure security settings to prevent

unauthorized access to your network. Because it is a radio device, the access point can communicate

beyond the physical boundaries of your building. Refer to the Cisco IOS Software Configuration Guide

for Cisco Aironet Access Points for information on how to configure some combination of these security

features to protect you network from intruders:

• Unique SSIDs that are not broadcast in the access point beacon

• WEP and additional WEP features, such as TKIP and broadcast key rotation

• Dynamic WEP and client authentication

Using the IP Setup Utility

IPSU enables you to find the access point’s IP address when it has been assigned by a DHCP server. You

can also use IPSU to set the access point’s IP address and SSID if they have not been changed from the

default settings.

Note IPSU can be used only on the following operating systems: Windows 95, 98, NT, 2000, ME, or XP.

Tip Another simple way to find the access point’s IP address is to look on the Status screen in the Aironet

Client Utility on a client device associated to the access point.

The sections below explain how to install the utility, how to use it to find the access point’s IP address,

and how to use it to set the IP address and the SSID.
