WIMIC Troubleshooting

Checking Basic Settings

Mismatched basic settings are the most common causes of lost connectivity with wireless clients. If the
wireless device does not communicate with client devices, check the areas described in this section.

SSID

Wireless clients attempting to associate with the wireless device must use the same service set identifier
(SSID) as the wireless device. If a client device SSID does not match the SSID of an wireless device in
radio range, the client device will not associate. The wireless device default SSID is tsunami.

WEP Keys

The Wired Equivalent Privacy (WEP) key you use to transmit data must be set up exactly the same on
the wireless device 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 set WEP Key 3 on the
wireless device to exactly the same value. The wireless device does not need to use Key 3 as its transmit
key, however.

Security Settings

Wireless clients attempting to authenticate with the wireless device must support the same security
options configured in the wireless device, such as Extensible Authentication Protocol (EAP) or Light
Extensible Authentication Protocol (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 the wireless device, 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 wireless device settings.
The wireless device MAC address that appears on the Status page in the Aironet Client Utility (ACU) is
Note
the MAC address for the wireless device radio.

Resetting to the Default Configuration

If you forget the password that allows you to configure the wireless device, you may need to completely
reset the configuration.
The following steps reset all configuration settings to factory defaults, including passwords, WEP keys,
Note
the IP address, and the SSID. The default username and password are both Cisco, which is
case-sensitive.
