RADIUS Authentication Server
If you enabled RADIUS Authentication on the AP, make sure that your network’s RADIUS servers are operational.
Otherwise, clients will not be able to log in. There are several reasons the authentication server services might be
unavailable, here are two typical things to check:
• Make sure you have the proper RADIUS authentication server information setup configured in the AP. Check the
RADIUS Authentication Server’s Shared Secret and Destination Port number (default is 1812; for RADIUS
Accounting, the default is 1813).
• Make sure the RADIUS authentication server RAS setup matches the AP.
TFTP Server
The “Trivial File Transfer Protocol” (TFTP) server allows you to transfer files across a network. You can upload
configuration files from the AP for backup or copying, and you can download configuration files or new software
images. The TFTP software is located on the AP Installation CD-ROM.
If a TFTP server is not configured and running, you will not be able to download and upload images and configuration
files to/from the AP. Remember that the TFTP server does not have to be local, so long as you have a valid TFTP IP
address. Note that you do not need a TFTP server running unless you want to transfer files to or from the AP.
After the TFTP server is installed:
• Check to see that TFTP is configured to point to the directory containing the AP Image.
• Make sure you have the proper TFTP server IP Address, the proper AP Image file name, and that the TFTP server
is connected.
• Make sure the TFTP server is configured to both send and receive, with no time-out.
