Security Settings; Wep Keys - Cisco Aironet 1130AG Quick Start Manual

SSID
Wireless clients attempting to associate with the access point must use the
same SSID as the access point. If a client device SSID does not match the
SSID of an access point in radio range, the client device will not associate.

WEP Keys

The WEP keys that 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 the same value for WEP Key 3
on the access point. However, the access point does not need to use WEP Key
3 as the transmit key.
Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet
Access Points for instructions on setting the access point WEP keys.

Security Settings

Wireless devices attempting to authenticate with your access point must
support the same security options configured on the access point, such as
EAP or LEAP, MAC address authentication, Message Integrity Check (MIC)
WEP key hashing, and 802.1X protocol versions.
