Chapter3 Troubleshooting 1240AG Series Autonomous Access Points
Checking Basic Settings
Default IP Address Behavior
When you connect a 1240 series access point running Cisco IOS Release 12.3(7)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, continues to send requests indefinitely.
Enabling the Radio Interfaces
In Cisco IOS Release 12.3(7)JA or later, the access point radios are disabled by default, and there is no
default SSID. You must create an SSID and enable the radios 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.
To enable the radio interfaces, follow these instructions:
Step1 Use your web-browser to access your access point.
Step2 At the prompts, enter the administrator username and password. The default username is Cisco and the
default password is Cisco. The username and password are case sensitive.
Step3 When the Summary Status page displays, click Network Interfaces > Radio0-802.11G and the radio
status page displays.
Step4 Click Settings and the radio settings page displays.
Step5 Click Enable in the Enable Radio field.
Step6 Click Apply.
Step7 Click Radio1-802.11A and the radio status page displays.
Step8 Repeat Steps 3 to 5.
Step9 Close your web-browser.
SSID
Wireless clients attempting to associate with the access point must use the same SSID as the access point.
If a client device’s SSID does not match the SSID of an access point in radio range, the client device will
not associate.
Note In Cisco IOS Release 12.3(7)JA or later, there is no default SSID. You must configure an SSID before
client devices can associate to the access point.
