Appendix A: Security Settings on Wireless
Clients and RADIUS Server Setup
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.
Note: The recommended sequence for security configuration is (1) set up security on the
access poin
t, 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 (None)
from an unsecure wireless client. With this initial connection, you can go to the access
point Administration Web pages and configure a security mode (Security).
When you re-configure 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 AT-TQ2403 Management Software.
