Checking Basic Settings
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 
“Configuring Basic Security Settings” section on page 3-9
 for 
instructions on configuring the SSID.
To enable the radio interfaces, follow these instructions:
Step 1
Use your web-browser to access your access point.
Step 2
When the Summary Status page displays, click Network Interfaces > Radio0-802.11G and the radio 
status page displays.
Step 3
Click Settings and the radio settings page displays.
Step 4
Click Enable in the Enable Radio field.
Step 5
Click Apply.
Step 6
Click Radio1-802.11A and the radio status page displays.
Step 7
Repeat Steps 3 to 5.
Step 8
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(4)JA and later
, there is no default SSID. You must configure an SSID before 
client devices can associate to the access point.
WEP Keys
The WEP key you use to transmit data must be set up exactly the same on your access point and any 
wireless devices with which it associates. For example, if you set WEP Key 3 on your client adapter to 
0987654321 and select it as the transmit key, you must also set WEP Key 3 on the access point to exactly 
the same value. The access point does not need to use Key 3 as its transmit key, however.
Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points for instructions 
on setting the access point’s WEP keys.
Security Settings
Wireless clients attempting to authenticate with your access point must support the same security options 
configured in the access point, such as EAP or LEAP, MAC address authentication, Message Integrity 
Check (MIC), WEP key hashing, and 802.1X protocol versions.
