Note

You can restore the access point to its factory defaults by unplugging 
the power jack and plugging it back in while holding the Mode 
button down until the Ethernet LED turns amber (approximately 2 to 
3 seconds).

Enabling the Radio Interfaces

In Cisco IOS Release 12.3(7)JA, 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 allows wireless associations from other 
devices. These changes to the default configuration improve the security of 
newly installed access points. Refer to the "Configuring Security Settings" 
section on page 33 for instructions on configuring the SSID.

Follow these steps to enable the radio interfaces:

1.

Browse to your access point.

2.

When the Summary Status page appears, click 

Radio0-802.11G

. The 

2.4-GHz radio status page appears.

3.

Choose the 

Settings

 tab at the top of the page. The radio settings page 

appears.

4.

Click 

Enable 

in the Enable Radio field.
