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.

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.

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.
