NOTE

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

 169.254.128.132

 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 

Reset to Factory Default 

Procedure

 resets configuration, but does not change the current AP Image. 

•

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 

Using the Command Line Interface (CLI)

 for CLI 

command syntax and parameter names.

•

ScanTool does not work over routers. 

You must be connected to the same subnet/physical LAN segment to use 

ScanTool. Note that ScanTool also works over the wireless interface; you can run it on a wireless client connected 
to the target AP or an AP connected to the same LAN segment/subnet.

•

If all else fails…

 Use the Forced Reload Procedure to erase the current AP Image and then download a new 

image. Once the new image is loaded, use the 

Reset to Factory Default Procedure

 to set the unit to factory default 

values and reconfigure the unit.
