Chapter 6 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 a 1200 series 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, continues to send requests indefinitely.
When you connect a 1200 series access point running Cisco IOS Release 12.2(15)JA or earlier 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, the access point assigns a default IP address of 10.0.0.1
Default SSID and Radio Behavior
In Cisco IOS Release 12.3(2)JA and earlier, the access point radio is enabled by default and the default SSID is tsunami.
In Cisco IOS Release 12.3(4)JAand later, the access point radio is disabled by default for security reasons, and there is no default SSID. 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 “Enabling the Radio Interfaces” section on page
Enabling the Radio Interfaces
In Cisco IOS Release 12.3(4)JA and 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:
Step 1 Use your internet browser to access your access point.
Step 2 At the prompt, enter the administrator username and password. The default username is Cisco and the default password is Cisco. The username and password are case sensitive.
Step 3 When the Summary Status page displays, click Network Interfaces >
Step 4 Click Settings and the radio settings page displays.
Step 5 Click Enable in the Enable Radio field and click Apply.
Step 6 Click
Step 7 Repeat Steps 3 and 4.
