Chapter5 Configuring the Bridge for the First Time
Using the IP Setup Utility

Protecting Your Wireless LAN

To prevent unauthorized access to your network, you must configure security settings. Because the
bridge is a radio device, the bridge communicates beyond the physical boundaries of your building.
Refer to the Cisco Aironet 1400 Series Wireless Bridge Software Configuration Guide to configure
security features to protect your network from intruders:
Unique SSIDs that are not broadcast in the bridge beacon
WEP and additional WEP features, such as TKIP and broadcast key rotation
Dynamic WEP and EAP authentication
Using the IP Setup Utility
IPSU enables you to find the bridge’s IP address when it has been assigned by a DHCP server. You can
also use IPSU to set the bridge’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.
The sections below explain how to install the utility, how to use it to find the bridge’s IP address, and
how to use it to set the IP address and the SSID.
