Chapter 3 Troubleshooting Autonomous Access Points
Checking Basic Settings
Checking Basic Settings
Mismatched basic settings are the most common causes of lost connectivity with wireless clients. If the
access point does not communicate with client devices, check the following areas.
Default IP Address Behavior
When you connect an 1130AG access point running Cisco IOS Release 12.3(2)JA or later software with
a default configuration to your LAN, the access point requests an IP address from your DHCP server,
and if it does not receive an IP address, it continues to send requests indefinitely.
Default SSID and Radio Behavior
In Cisco IOS Relese 12.3(2)JA2 and earlier, the access point radios are enabled by default and the default
SSIDs are tsunami.
In Cisco IOS Release 12.3(4)JA and later, the access point radios are disabled by default, and there are
no default SSIDs. You must create an SSID and enable the radio before the access point will allow
wireless associations from other devices. These changes to the default configuration improve the
security of newly installed access points. Refer to the Cisco IOS Software Configuration Guide for Cisco
Aironet Access Points for instructions on configuring the SSID and the
“Enable Radio Interfaces”
section on page 3-5 for instructions on enabling the radio interfaces.
