Introduction
The D-Link DI-524UP Wireless Router is an 802.11b/g high-performance, wireless
router that supports high-speed wireless networking at home, at work or in public
places.
The 802.11g standard is backwards compatible with 802.11b products. This means that
you do not need to change your entire network to maintain connectivity. You may
sacrifice some of 802.11g’s speed when you mix 802.11b and 802.11g devices, but you
will not lose the ability to communicate when you incorporate the 802.11g standard into
your 802.11b network. You may choose to slowly change your network by gradually
replacing the 802.11b devices with 802.11g devices.
In addition to offering faster data transfer speeds when used with other 802.11g
products, the DI-524UP has the newest, strongest, most advanced security features
available today. When used with other 802.11g WPA or WPA2 (WiFi Protected Access)
and 802.1x compatible products in a network with a RADIUS server, the security
features include:
• WPA Wi-Fi Protected Access authorizes and identifies users based on a secret
key that changes automatically at a regular interval. WPA uses TKIP (Temporal
Key Integrity Protocol) to change the temporal key every 10,000 packets (a packet
is a kind of message transmitted over a network.) This insures much greater
security than the standard WEP security. (By contrast, the older WEP encryption
required the keys to be changed manually.)
• WPA2, based on the IEEE 802.1i Wi-Fi certified standard, goes a level beyond
the previous WPA by enhancing security with a new encryption code.
Employing AES (Advanced Encryption Standard), and yet still backwards
compatible with WPA, WPA2 utilizes 802.1X and EAP (Extensible
Authentication Protocol) to verify users on the wireless network using a
Pre-Shared Key. Once all users on the LAN have been authenticated, there can
be a securely encrypted flow of information between all parties on the LAN.
For home users that will not incorporate a RADIUS server in their network, the security for
the DI-524UP, used in conjunction with other 802.11g products, will still be much
stronger than ever before. Utilizing the Pre Shared Key mode of WPA, the DI-524UP will
obtain a new security key every time it connects to the 802.11g network. You only need
to input your encryption information once in the configuration menu. No longer will you
have to manually input a new WEP key frequently to ensure security, with the DI-524UP,
you will automatically receive a new key every time you connect, vastly increasing the
safety of your communications.
The DI-524UP also comes equipped with one USB 1.1 port on the rear panel that
supports printer sharing.
