Checking Basic Settings
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 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 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 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 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.
