Clear this check box to block transmissions from end devices that
are not using WEP encryption.
WEP Transmit Key
Determines which of the four WEP keys this access point uses to
transmit data.
WEP Key 1 through WEP Key 4
For WEP 64, enter five ASCII characters or five hex pairs. For WEP
128, enter 13 ASCII characters or hex pairs. For WEP 128, enter 16
ASCII characters or hex pairs.
To enter a hexadecimal key, prefix it with 0x. For example, the
ASCII key ABCDE is equivalent to 0x4142434445.

Implementing
an 802.1x
Security
Solution
AT-WA7500 access points can help implement 802.1x security in an
802.11b or 802.11a network. The IEEE 802.1x standard provides an
authentication protocol for 802.11 LANs. 802.1x provides strong
authentication, access control, and key management, and lets wireless
networks scale by allowing centralized authentication of wireless end
devices.
The 802.1x authentication process uses a RADIUS server, which is the
authentication server, and access points, which are the authenticators,
to manage the wireless end device authentication and wireless
connection attributes. Extensible Authentication Protocol (EAP)
authentication types provide devices with secure connections to the
network. They protect credentials and data privacy. Examples of EAP
authentication types include Transport Layer Security (EAP-TLS) and
Tunneled Transport Layer Security (EAP-TTLS).
To implement 802.1x security, you must have the following:
‰ A trusted certificate authority (CA), which issues digital
authentication certificates. The authentication server must have a
certificate installed on it. Also, if the end devices are using EAP-
TLS, each one needs a client certificate.
‰ An authentication server (RADIUS server), which is software that is
installed on a PC or server on your network or an EAS. The
authentication server accepts or rejects requests from end
devices that want to communicate with the 802.1x-enabled
network.
