This section helps you locate problems related to the AP device setup. For details about RADIUS, TFTP, serial
communication programs (such as HyperTerminal), Telnet applications, or web browsers, please refer to the
documentation that came with the application for assistance.
Troubleshooting Concepts
The following list identifies important troubleshooting concepts and topics. The most common initialization and
installation problems relate to IP addressing. For example, you must have valid IP addresses for both the AP and the
management computer to access the unit's HTTP interface.
•
IP Address management is fundamental.
•
Factory default units are set for "Dynamic" (DHCP) IP Address assignment. The default IP address for the AP
is 10.0.0.1 if your network does not have a DHCP server. If you connect the AP to a network with an active DHCP
server, then use ScanTool to locate the IP address of your unit. If a DHCP server is not active on your subnet, then
use ScanTool to assign a static IP address to the unit.
•
The Trivial File Transfer Protocol (TFTP) provides a means to download and upload files. These files include
the AP Image (executable program) and configuration files.
•
If the AP password is lost or forgotten, you will need to reset to default values. The
Procedure
resets configuration, but does not change the current AP Image.
•
If all else fails... Use the
image. Once the new image is loaded, use the
values and reconfigure the unit.
•
The AP Supports a Command Line Interface (CLI). If you are having trouble locating your AP on the network,
connect to the unit directly using the serial interface and refer to
syntax and parameter names.
