Introduction
Thissectionisdesignedtohelpyouisolateandresolveproblemswithyour
AP-2000 Access Point and is updated frequently. To ensure you have the
latest version, contact your technical support provider.
The AP-2000 technical staff collects and maintains this information. Your
feedback on recommendations, corrections, or clarifications will help to keep
the guide accurate and up to date. Provide comments and feedback to your
technical support representative.
Scope
This troubleshooting reference supplements the ORiNOCO AP-2000 User's
Guide, which is the principal source of setup and configuration information. A
related manual, the ORiNOCO Client Manager User’s Guide, provides
information for configuring and using a wireless client (typically a laptop).
Each userguide contains appropriate proceduresand additional information.
This guide provides high level procedures for using the Command Line
Interface (CLI) over the Serial Port or Ethernet to setup the AP-2000. For
detailed information on using the CLI, please refer to the AP-2000 CLI
Reference Manual.

Introduction

For details about RADIUS, TFTP, Serial communications program (such as
HyperTerminal), and Telnet applications or web browser, please refer to their
respective documentation. The AP-2000 User’s Guide contains information
for ScanTool, an application provided with AP-2000. ScanTool helps locate
AP-2000 units on a subnet.
The most common initialization and installation problems relate to IP
Addressing. For example, you must have valid IP Addresses for both the
AP-2000 and the TFTP server before you can transfer files over Ethernet.
The following list identifies important troubleshooting concepts and topics.
QRefer to the User Guides and Manuals
QIP Address management is fundamental. Refer to the “Documenting
Your Configuration” section in the AP-2000 User’s Guide.
QFactory default units are set for “Dynamic” (DHCP) IP Address
assignment. The default IP Address for the AP-2000 is 10.0.0.1. If you
connect the AP-2000 unit to a network with an active DHCP server, then
use ScanTool to locate the IP Address of your unit. If a DHCP server is
notactiveonyoursubnet,thentheScanToolcanbeusedtoconfigure
your AP-2000.
QThe Trivial File Transfer Protocol (TFTP) provides a means to
download and upload files. These files include the AP-2000 Image
(executable program) and configuration files.
QIf the AP-2000 password is lost or forgotten, you will need to reset
to default values. The Reset to Factory Default procedure resets your
configuration, but does not change the current AP Image.

Introduction
5
QIf all else fails… The Reset to Factory Default procedure erases the
current AP-2000 Image and sets the unit to factory default values. Then
you can download a new image and configure the unit.
QAP-2000 Supports a Command Line Interface (CLI). If you are having
trouble locating your AP-2000 on the network, connect to the unit directly
using the serial interface.

AP-2000 Connectivity Issues
AccessPointwillnotboot
The Access Point unit shows no activity (LEDs,including power LED, are not
illuminated). Check the following:
1. Make sure the AP-2000 power supply is operating and connected to the
unit correctly.
2. Make sure all cables are connected to the correct ports on the AP-2000.
3. Check your power source.
4. If you are using an Active Ethernet hub, verify that there is a valid power
source applied to the AP-2000.
Serial link does not work
If the Access Point cannot be reached using the serial port interface, check
the following:
1. Make sure you are using the proper serial port cable adapter. The
adapter provided with your kit converts a standard serial port DB-9
connector to the AP-2000 Mini-DIN connector.
2. Check the cable connection between the Access Point and the client
station.
3. Double-check the physical network connections.

4. Make sure your PC terminal program (such as HyperTerminal) is active
and configured to the following values:
— Com Port: (COM1, etc. depending on your computer)
— Baud rate: 9600
— Data bits: 8
— Stop bits: 1
— Flow Control: None
— Parity: None
— Line Feeds with Carriage Returns
5. If the HyperTerminal session is only receiving data, set the “line feeds
with carriage return” option as described below:
a. Select File -> Properties -> Settings -> ASCII Setup -> Send
Line Ends with Line Feeds.
b. Click OK twice.
The HyperTerminal session will now allow you to transmit and receive
data to and from the AP-2000.
6. Make sure the Access Point and the client station both have the same
serial port configuration.

AP-2000 Connectivity Issues

Ethernet link does not work
If you cannot access the HTTP (web browser) Interface or the Internet from
the Access Point, perform the following checks:
1. “Ping” the Access Point. If you cannot ping the Access Point, make sure
you have the correct IP Address for the unit you are working with. If the
AP-2000 responds to the ping, then the Ethernet Interface is working
properly; continue with this procedure.
2. Make sure you are using one of the following web browsers: Microsoft
Internet Explorer 5.0 or better, or Netscape 6.0 or better.
3. Make sure the “Proxy Server” on your web browser is not enabled.
4. Make sure you have not exceeded the maximum number of web, Telnet/
CLI, or serial CLI sessions allowed.
5. Double-check the physical network connections. Use a known-good unit
to ensure the network connection is present.
6. Perform network infrastructure troubleshooting (check switches,
routers, etc).

Basic Setup and Configuration Problems

Basic Setup and Configuration Problems
Lost AP-2000, Telnet, or SNMP password
1. Perform the Reset To Factory Default procedure described in this guide.
This procedure resets system and network parameters, but does not
affect the AP-2000 Image. The default AP-2000 password is “public”,
and the default Telnet password is also “public”.
2. Document your password(s) in the form provided in the “Documenting
your Configuration” section in the AP-2000 User’s Guide.
Client cannot connect
The client station cannot associate with the Access Point. Check the
following:
1. Confirm the Network Name of the Access Point using the HTTP (web)
Interface or the CLI.
2. Make sure the active Network Name on the client machine matches the
AP-2000 Network Name. Each PC Card should have a unique Network
Name.
3. The Client Manager software allows you to store Network Names in
configuration profiles. Make sure you are using the correct profile for
your location.
Network Names are usually allocated and maintained by your network
administrator.

Basic Setup and Configuration Problems
11
Access Point is slow to respond
If the Access Point takes a long time to become available, check the
following items:
1. Make sure the DHCP server is set up to allocate IP Addresses
dynamically. In the Access Point, the default IP Address Assignment
mode is dynamic (DHCP).
a. To find the current IP Address using DHCP, check the IP Client
TableintheDHCPServer.MatchtheAP-2000MACAddressinthe
table to the one on your unit.
b. If you do not have a DHCP server on your network, the default static
IP Address is 10.0.0.1.
2. Or use ScanTool to locate the current AP-2000 IP Address. Once
you have the current IP Address, use the HTTP or CLI Interface to either
set the unit to DHCP mode or assign a static IP Address.
3. If you use static IP Address assignments, and cannot access the unit
over Ethernet, use the “Setting IP Address using serial port and normal
CLI” procedure in this guide.
a. Verify that the static IP Address assigned to the Access Point is not
a duplicate within the network. Power down the AP-2000 and ping
the IP Address.
b. If the ping is successful, there is a duplicate IP Address on your
network.
4. Perform the Reset To Factory Default procedure in this guide. This will
reset the unit to DHCP mode. If there is a DHCP Server on the same
subnet, the DHCP Server will assign an IP Address to the AP-2000.

5. Verify that there is only one DHCP Server active on the network at one
time. The AP-2000 has DHCP service capability. This could conflict with
a network DHCP server.
6. Verify the level of traffic on the network.
7. Reboot the Access Point.
HTTP (browser) or Telnet Interface does not work
If your client station cannot reach the HTTP or Telnet Interface, then:
1. Use the CLI over the serial port to check the SNMP Table, which can be
restricting access to Telnet and HTTP. For more information refer to the
AP-2000 CLI Reference Manual.
2. “Ping” the Access Point. If you cannot ping the Access Point, make sure
you have the correct IP Address for the unit you are working with.
3. Make sure you have not exceeded the maximum number of web, Telnet/
CLI, or serial CLI sessions allowed.
4. Make sure you are using one of the following web browsers: Microsoft
Internet Explorer 5.0 or better, or Netscape 6.0 or better.
5. Make sure the “Proxy Server” on your web browser is not enabled.

TelnetCLIdoesnotwork
1. Make sure you have the proper IP Address. In the Telnet connection
dialog, enter the IP Address of the Access Point you want to connect to.
From a DOS prompt, type:
C:\> telnet <IP Address>
2. Use the CLI over the serial port to check the SNMP Table, which can be
restricting access to Telnet and HTTP. For more information refer to the
AP-2000 CLI Reference Manual.
3. Make sure you have not exceeded the maximum number of web, Telnet/
CLI, or serial CLI sessions allowed.
TFTP Server does not work
1. Make sure the TFTP Server has been started.
2. Verify the IP Address of the TFTP Server. The server may be local or
remote, so long as it has a valid IP Address.
3. Configure the TFTP Server to “point” to the folder containing the file to be
downloaded (or to the folder in which the file is to be uploaded).
4. Verify that you have the proper AP-2000 Image file name and directory
path.

Online Help is not available
The online Help does not appear when the “Help” button is pressed on the
web interface. Check the following:
1. The default location of the Help files is:
C:\Program Files\Dell_TrueMobile\AP\Help\
2. Make sure the Help files are installed on your hard drive or on the server
(as indicated by your network administrator).
3. From the HTTP Interface, verify the location of the Help files specified
under the Help tab. Click on the Commands button, then the Help tab.
Change the specified location if necessary.
Problems with HTTP Interface
If changes made in the HTTP Interface are not taking effect, perform the
following:
1. Close your web browser and restart it. Login to the Access Point and
make configuration changes. Reboot the unit if directed to do so.
2. Reboot the AP-2000 by clicking on the Command button, selecting the
Reboot tab, and clicking on Reboot. Wait for the Access Point to finish
rebooting before accessing the web browser again.

and install the latest ORiNOCO Client Manager and PC Card Driver
software from http://www.orinocowireless.com.
Intermittent loss of connection
QMake sure you are within range of an active AP-2000. You can see the
signal strength using the SNR gauge on the ORiNOCO Client Manager.

Client Connectivity Issues
16
Client cannot connect to network
If the client can associate with the Access Point, but cannot access the
network, check the following:
1. Verify the IP Address of the client station. If the IP Address is valid, then
ping the AP-2000.
a. If the client can ping the Access Point, but cannot connect to the
network, there may be a network configuration problem.
b. If the client station cannot ping the Access Point, then verify the
connection status and the encryption settings in the Client Manager.
c. Make sure the client station is connected to the correct AP-2000 by
verifying the Network Name.
2. If the Access Point is configured for DHCP, go the the HTTP Interface
and select the Configure button, then the Network tab. Verify your
DHCP settings and check the DHCP Server log for error messages.

When to reset the AP-2000
17
When to reset the AP-2000
Under the following conditions, and if the LED indicators show normal status,
the AP-2000 may need to be rebooted (reset). Reset through the HTTP
Interface, the CLI, or by pressing the RESET button on the AP-2000 unit.
Conditions that indicate a need for rebooting are:
QA static configuration parameter was changed through a management
interface but it appears not to have taken effect. (The web interface will
pop up a message to notify that a particular parameter change will need
a reboot in order to take effect).
QClients can not connect to the AP-2000, and the Access Point
configuration is correct.
QClients can not access the network although they associate with the
AP-2000, and station and Access Point configurations are correct.
QThe AP-2000 responds to a ping, but does not respond to any of the
management interfaces (Web, Telnet, and SNMP).
QThe AP-2000 does not respond on the serial interface.
QThe Access Point sent out any of the following TRAP messages, but did
not reboot automatically:
— WatchDog Timer Expired
— RADIUS Server Not Responding
— Module Not Initialized
— Device Rebooting
— Task Suspended

Reset and Reload Procedures
18
Reset and Reload Procedures
IP Address management is fundamental. We suggest you create a chart to
document and validate the IP addresses for your system.
If the password is lost or forgotten, you will need to reset the AP-2000 to
default values. The Reset to Factory Default procedure resets
configuration settings, but does not change the current AP Image. The
Forced Reload procedure erases the current AP Image if you need to
download a new image.
It is useful to set up the serial port and use your terminal emulator to monitor
AP-2000 activity. Serial port setup is described in “Troubleshooting”.
Reset to Factory Default procedure
Use this procedure to reset the network configuration values, including the
AP-2000 IP Address, Subnet Mask, and so on. The current AP Image is not
deleted. This procedure may required if the AP-2000 password is forgotten.
1. Press and hold the RELOAD button for about 10 seconds. Result: The
AP-2000 reboots, and the factory default network values are restored.
2. If not using DHCP, use the ScanTool or normal CLI to set the AP-2000 IP
Address, Subnet Mask, and so on. Please refer to the “Command Line
Interface Reference Manual” for CLI information.

Reset and Reload Procedures
19
Forced Reload procedure
Use this procedure to force the AP-2000 back to default network
configuration values and download a new AP Image. This procedure may be
required when the password is forgotten or the current AP Image is missing
or corrupted.
In this procedure, use the Bootloader CLI over the serial port to set the IP
Address and download a new AP Image.
1. While the AP Image is running, press the RESET button. Result: The
AP-2000 reboots and the indicators begin to flash.
NOTE:
By completing Step 2, the firmware in the Agere AP-2000 will be
erased. A serial cable will be required to reload firmware.
2. Press and hold the RELOAD button for about 20 seconds until the
POWER LED turns amber. Result: The AP-2000 deletes the current AP
Image and Configuration files. The Bootloader CLI becomes active. The
following procedure describes how to use the Bootloader CLI to assign
an IP Address and download a new AP Image.

Reset and Reload Procedures
20
Initializing the AP-2000 using the Bootloader CLI
In some cases, specifically when a bad AP Image prevents successful
booting, you may need to use the Bootloader CLI to download a new
executable AP Image. If you need to force the AP-2000 to factory default
state, use the “Forced Reload Procedure” above.
To download the AP Image, you will need an Ethernet connection to the
computer on which the TFTP server resides. This can be any computer on
the LAN, or connected to the AP-2000 with a “crossover” Ethernet cable.
You must also connect the AP-2000 to a computer with a standard serial
cable and use a terminal client, such as HyperTerminal. From the terminal,
enter CLI Commands to set the IP Address and download an AP Image.
Preparing to download the AP Image
Before starting, you need to know the AP-2000 IP Address, Subnet Mask,
the TFTP Server IP Address, and the AP Image file name. Ensure the TFTP
sever is running and configured to point to the folder containing the image to
be downloaded.
Download procedure
1. Connect the computer serial cable to the AP-2000 serial port.
2. Start TFTP Server, and ensure the new AP Image file is in the TFTP
directory. In this procedure, TFTP downloads an AP Image to the
AP-2000.
