Appendix A. Configuring Security Settings
on Wireless Clients
Typically, users will configure security on their wireless clients for access to many different
networks (access points). The list of "Available Networks" will change depending on the
location of the client and which APs are online and detectable in that location.* Once
an AP has been detected by the client and security is configured for it, it remains in the
client's list of networks but shows as either reachable or unreachable depending on the
situation. For each network (AP) you want to connect to, configure security settings on
the client to match the security mode being used by that network.
We describe security setup on a client that uses Microsoft Windows client software for
wireless connectivity. The Windows client software is used as the example because of
its widespread availability on Windows computers and laptops. These procedures will
vary slightly if you use different software on the client (such as Funk Odyssey), but the
configuration information you need to provide is the same.
The recommended sequence for security configuration is (1) set up security on the access
point, and (2) configure security on each of the wireless clients.
We expect that initially, you will connect to an access point that has no security set (plain
text mode) from an unsecure wireless client. With this initial connection, you can go to
the access point Administration Web pages and configure a security mode (Advanced >
Security).
When you reconfigure the access point with a security setting and click "Update", your
wireless client will be disassociated and you will lose connectivity to the AP Administration
Web pages. In some cases, you may need to make additional changes to the AP security
settings before configuring the client. Therefore, you must have a backup Ethernet (wired)
connection.
The following sections describe how to set up each of the supported security modes
on wireless clients of a network served by the D-Link DWL-2210AP.
• Network Infrastructure and Choosing Between Built-in or External Authentication
Server
• Make Sure the Wireless Client Software is Up-to-Date
• Accessing the Microsoft Windows Wireless Client Security Settings
• Configuring a Client to Access an Unsecure Network (Plain Text mode)
• Configuring Static WEP Security on a Client
• Configuring IEEE 802.1x Security on a Client
• Configuring WPA with RADIUS Security on a Client
• Configuring WPA-PSK Security on a Client
* The exception to this is if the access point is set to prohibit the broadcast of its network name. In this case
the SSID will not show up in the list of Available Networks on the client. Instead, the client must have the exact
network name configured in the network connection properties before it will be able to connect.
