Troubleshooting
This chapter provides information on the following:
• Troubleshooting Concepts
• Symptoms and Solutions
• Recovery Procedures
• Related Applications
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 see the
documentation that came with the respective 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 Soft Reset to Factory
Defaults or Hard Reset to Factory Defaults procedures reset the configuration, but do 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 see 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 configuration file and then
download a new image.
