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
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
• 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
Using the Command Line Interface (CLI)
to set the unit to factory default values and reconfigure the unit.
