Checking Basic Settings Chapter 8 Troubleshooting Checking Basic Settings Mismatched basic settings are the most common causes of lost connectivity with wireless clients. If the access point does not communicate with client devices, check the following areas. 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. The access point default SSID is tsunami. 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 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. Resetting to the Default Configuration If you forget the password that allows you to configure the access point, you may need to completely reset the configuration. You can use the MODE button on the access point or the web-browser interface. Note The following steps reset all configuration settings to factory defaults, including passwords, WEP keys, the IP address, and the SSID.

Checking Basic Settings
Checking Basic Settings
Mismatched basic settings are the most common causes of lost connectivity with wireless clients. If the
access point does not communicate with client devices, check the following areas.
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. The access point default SSID is
tsunami
.
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
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.
Resetting to the Default Configuration
If you forget the password that allows you to configure the access point, you may need to completely
reset the configuration. You can use the MODE button on the access point or the web-browser interface.
Note
The following steps reset
all
configuration settings to factory defaults, including passwords, WEP keys,
the IP address, and the SSID.
