Configuring SSID Settings 101
5 Configuring Access Point Settings
If the wireless network topology changes (for example, a DWS-3000 switch reboots) while the
L3 tunneling feature is in use, you should perform an ARP refresh on wired clients to speed up
the process of re-establishing connectivity to the tunneled network.
For information about how to configure a network to use L3 tunneling, including CLI
commands and Web configuration procedures, see Appendix C, “L3 Roaming Example” on
page 215.
Configuring AP Security
The Default AP profile does not use any security mechanism by default. In order to protect
your network, we strongly recommend that you select a security mechanism so that
unauthorized wireless clients cannot gain access to your network.
From the Wireless Network Configuration page, you can select None, WEP or WPA/WPA2
as the WLAN security mechanisms, as Figure 44 shows. The default is None.
Figure 44. AP Network Security Options
The following sections describe the security mechanicians.
Using No Security
If you select None as your security mode, no further options are configurable on the AP. This
mode means that any data transferred between the D-Link Access Point and the associated
wireless clients is not encrypted, and any wireless client can associate with the AP.
This security mode can be useful during initial network configuration or for problem solving,
but it is not recommended for regular use on the internal network because it is not secure.
Using Static or Dynamic WEP
Wired Equivalent Privacy (WEP) is a data encryption protocol for 802.11 wireless networks. If
you select this security mechanism, all wireless clients and access points on the network are
configured with a 64-bit (40-bit secret key + 24-bit initialization vector (IV)), 128-bit (104-bit
secret key + 24-bit IV), or 152-bit (128-bit secret key + 24-bit IV) Shared Key for data
encryption.
Static WEP is not the most secure mode available, but it offers more protection than setting the
security mode to None as it does prevent an outsider from easily sniffing out unencrypted
wireless traffic.
Dynamic WEP is more secure than Static WEP, but you need a RADIUS server to manage the
dynamically generated keys.
WEP encrypts data moving across the wireless network based on a static key. (The encryption
algorithm is a “stream” cipher called RC4.)
