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. In Cisco IOS Release 12.3(2)JA2 and earlier, the access point default SSID is tsunami.
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.
If a wireless client is unable to authenticate with your access point, contact the system administrator for
proper security settings in the client adapter and for the client adapter driver and firmware versions that
are compatible with the access point settings.
Note The access point MAC address that appears on the Status page in the Aironet Client Utility (ACU) is the
MAC address for the access point radio. The MAC address for the access point Ethernet port is printed
on the label on the back of the access point.
Running the Carrier Busy Test
You can use the carrier busy test to find the least congested channel for a radio interface (802.11b/g or
802.11a). You should typically run the test several times to obtain the best results and to avoid temporary
activity spikes.
