Introduction

Thissectionisdesignedtohelpyouisolateandresolveproblemswithyour
AP-2000 Access Point and i s 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 supplem ents the ORiNOCO AP-2000 User's
Guide, which is the principal source of setup and configuration information. A

related manual, the ORiNOCO Client M a nager User’s Guide, provides
information for configuring and using a wireless client (typically a laptop).
Eachuser guide containsappropriate procedures andadditional information.

This guide provides high level procedures for using the Command Line
Interface (CLI) over t he Serial Port or Eth ernet to setup th e 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 applicat ions 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. F or example, you must have valid IP Addresses for both the
AP-2000 and the TFTP server before you can transfer files over Ethernet.
The follow ing list identifies important troubleshooting concepts and topics.

Q Refer to the User G u ides and Manual s
Q IP Ad dress management is fundamental. Refer to the “Documenting

Your Configuration” section in the AP-2000 User’s Guide.

Q Factory 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 Sc anTool to locate the IP A ddress of your unit. If a DHCP server is
notactiveonyoursubnet,thentheScanToolcanbeusedtoconfigure
your AP-2000.

Q The 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.

Q If th e AP-2000 password is los t 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.

4

Introduction

Q If all else fails… The Reset to Factory Default procedure erases the

current AP-2000 Image and sets t he unit to factory default values. Then
you can download a new image and configure the unit .

Q AP-2000 Supports a Command Line Interface (CLI). If you are having

trouble loc ating your AP-2000 on the netw ork, connect to the unit direc tly
using the serial interface.

AP-2000 Connectivity Issues

AP-2000 Connectivity Issues

AccessPointwillnotboot

TheAccess Point unit showsno activity (LEDs, includingpowerLED, are not
illuminated). Check the following:

1. Make sure the AP-2000 pow er 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 p ower
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.

7

AP-2000 Connectivity Issues

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 -> Proper ties -> Settings -> ASCII Setup - > Send

Line Ends with Line Feeds.

b. Click OK twice.

The HyperTe rminal 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.

8

AP-2000 Connectivity Issues

Ethernet link does not work

If you cannot access the HTT P (web browser) Interface or the Internet from
the Access Point, perform the following checks:

1. “Ping” the Acc ess 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 t he “Proxy Server” on your web br owser 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 p hysical network c o nnections. Use a known-good unit
to ensure the network connection is present.

6. Perform network infrastructure troubleshooting (check s witches,
routers, etc).

Basic Setup and Con figuration Problems

Basic Setup and Configuration Problems

Lost AP-2000, Telnet, or SNMP password

1. Perform the Reset To FactoryDefault proceduredescribedin 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 pass word 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. C heck the
following:

1. Confirm the Network Name of the Access Point usi ng the HTTP (web)
Interface or the CLI.

2. Make sure the active Network Name on the client machine matches the
AP-200 0 Network Name. Each PC Card should have a unique Network
Name.

3. The Client Manager software allows you to s tore 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.

10

Basic Setup a nd Configuration Problems

Access Point i s 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 def ault 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 serve r on your network, the default static

IP Address is 10.0.0.1.

2. Or use ScanTool to lo cate the current AP-2000 IP Address. On ce
you have the curren t 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 Fac tory 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 Se rver will assign an IP Address to the AP-2000.

11

5. Verify that there is only one DHCP Server active on t he network at one
time. The AP -2000 has DHCP service capability. This could conflict with
a n etwork 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 I nterface, 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 bet ter.

5. Make sure the “Proxy Server” on your web browser is not enabled.

Basic Setup a nd Configuration Problems

TelnetCLIdoesnotwork

1. Make sure you have the proper IP Addr ess. In the Telnet connecti on
dialog, ent er 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, w hich can be
restricting access to Telnet and HTTP. For more information refer to the
AP-2000 CL I Reference Ma nual.

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 T FTP 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 fold er in which the file is to be uploaded).

4. Verify that you have the proper AP-2000 Image file name and directory
path.

13

Basic Setup and Con figuration Problems

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 indicat ed by your network administrator).

3. From the HTTP Interface, verify the location of the Help files specified
under the Help tab. Click on t he Commands button, then the Help tab.
Change t he 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.

Q Make sure you are using the latest PC Card driver software. Download

and install the latest ORiNOCO Client Manager and PC Card Driver
software from h ttp://www.orinocowireless.com.

Intermittent loss of connection

Q Make sure you are within range o f an active AP-2000. You can see the

signal strength using the SNR gauge on the ORiNOCO Client Manager.

15

Client Connect ivity Issues

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

16

and select the Configure button, then the Ne twork tab. Verify your
DHCP settings and check the DHCP Server log for error messages.

When t o reset the AP -2000

Underthe followingconditions,and if theLED indicatorsshow normal status,
the AP-2000 m ay need to be rebooted (reset). Reset through the HTTP
Interface, the CLI, or by pressing the RESET button o n the AP- 2000 unit.
Conditions that indicate a need for rebooting are:

Q A 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).

Q Clients can not connect to the AP-2000, and the Access Point

configuration is correct.

Q Clients can not ac cess the netwo rk although they associate with the

AP-2000, and station and Access Point configurations a re correct.

Reset and Re load Procedures

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 “Troubleshoot ing”.

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 curre nt 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, u se the ScanTool or normal CLI t o set the AP-2000 IP
Address, Subnet Mask, and so on. Please refer to the “Command Line
Interface Reference Man ual” for CLI information.

18

Reset and Reload Procedures

Forced Reload procedure

Use this procedure to force the AP-2000 back to default network
configuratio n values and d ownload a new AP Image. This pr ocedure 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 butt on. Result: The
AP-2000 reboots and the indicators begin to flash.

NOTE:

By compl eting 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 REL OAD button for about 20 seconds until t he
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.

19

Reset and Re load Procedures

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 t o 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.

20

Reset and Reload Procedures

3. Open your terminal emulator, set the following connection propert ies,
and then co nnect.

Q Com Port: <COM1, COM2, etc., depending on your computer>
Q Baud rate : 9600
Q Data Bits: 8
Q Stop bits: 1
Q Flow Control: None
Q Parity: None

4. Enable the “ASCII Setup” settings by selecting “Send line ends with line
feeds”. Res ult: HyperTermin al sends a line return at t he end of each line
of code.

5. Press the RESET b utton on the AP-2000. Result: The terminal display
shows Power On Self Tests (POST) activity. After approximately 30
seconds, a message indicates:

periodically

. After this message appears, pr ess the ENTER key

repeatedly until the following prompt appears.

[Device name]>

6. Enter only the following statements.

[Device name]> set ipaddrtype <Access Point IP Address>

[Device name]> set ipsubmask <Subnet Mask>

[Device name]> set ipaddrtype static

[Device name]> set tftpipaddr <TFTP Server IP Address>

[Device name]> set tftpfilename <AP Image File Name>

[Device name]> set ipgw <Gateway IP Address>

[Device name]> reboot 0

21

Reset and Re load Procedures

Example:

[Device name]> set ipaddrtype 10.0.0.12

[Device name]> set ipsubmask 255.255.255.0

[Device name]> set ipaddrtype static

[Device name]> set tftpipaddr 10.0.0.20

[Device name]> set tftpfilename MyImage

[Device name]> set ipgw 10.0.0.30

[Device name]> reboot 0

Result: The AP -2000 will reboot and then d ownload the image file. Observe
the

TFTP display and you should see downloading activity begin after a few

seconds. When downloading has stopped, the AP-20 00 is ready for
configuration, providing the AP-2000 IP Address is correct.

7. Once the AP-2000 image is d ownloaded and you h ave a valid AP-2000

22

IP Address, configure the A P-2000 as desc ribed in "Configu ration".

Reset and Reload Procedures

Setting IP Address using serial port and normal CLI

Use the following procedure to set an IP Address over the serial port using
the normal CLI. The network adm inistrator typically provides the AP-200 0 IP
Address.

Hardware and software requirements

Q Standard serial data (RS-232) cable with a male DB-9 connector on one

end and a female DB-9 connector on the other end.

Q Serial Port Adapter pl ug to convert DB-9 to Mini-DIN8 (supplied with kit).
Q ASCII Terminal software, such as HyperTerminal.

Attaching the serial port cable

1. Remove power from the AP-2000 and your computer.

2. Connect the m ale end of the serial port cable to the Serial Port Adapter,
and then plug the Serial Port Adapter into the Mini-DIN8 connector on
the back of the AP-2000.

3. Connect the female end of the serial port cable to the computer.

4. Restart the computer and powe r up the AP-2000.

23

Reset and Re load Procedures

Initializing the IP Address using normal CLI

After installing the serial port cable, you may use the CLI to communicate
with the AP-2000. You may use most generic terminal programs, such as
HyperTerminal. Once the IP Address has been assigned, use the HTTP
Interface or the CLI to complete configuration. Many web sites offer
shareware or commercial terminal programs you can download.

Use the following procedure to initialize the AP -2000 IP Address.

1. Open your terminal emulator, and then set the following connection
properties:

Q Com Port: <COM1, COM2, etc., depending on your compute r>
Q Baud rate: 9600
Q Data B its: 8
Q Stop bits: 1
Q Flow Control: None
Q Parity: None

2. Enable the “AS CII Setup” settings by selecting “Send line ends with line
feeds”. Result: HyperTerminal sends a line return at the end of each line
of code.

3. Press the RESET button on the AP-2000 (located on the LED Indicator
side of the unit). Result: The terminal display shows Power On Self Tests
(POST) activity, and then displays a CLI prompt, similar to the example
below. This process may take up to 90 seconds.

[Device name]> Please enter password:

24

Reset and Reload Procedures

4. Enter the password (default is "public"). Result: The terminal displays a
welcome message and then the CLI Prompt:

[Device name]>

5. Enter show ip. Result: Ne twork parameters appear:

[Device name]> show ip

IP Address: 10.0.0.1
Subnet Mask: 255.0.0.0
Default Router: 10.0.0.1
DefaultTTL:64
Address Type: 1

6. Change th e IP Address and other network values using set and reboot
CLI commands, similar to the example dialog below (use your own IP
Address andSubnet Mask). Result:Aftereach entrythe CLIremindsyou
to reboot; however wait to reboot until all comm ands have been entered.

[Device name]> set ipaddrtype static

[Device name]> set ipaddr <IP Address>

[Device name]> set ipsubmask <Subnet Mask>

[Device name]> set ipgw <Default Gateway IP Address>

[Device name]> reboot 0

7. After the AP-2000 reboots, verify the new IP Address by rec onnecting,
and then entering a show ip CLI statement (as in Step 5). Alternatively,
youcanusetheping network co mmand from networked computers to
test the new IP Address.

8. When the proper IP Address is set, use CLI or the HTTP Interface over
the LAN to complete configuration and manage operations.

RADIUS Authentication s erver

If the RADIUS authentication server is selected for authentication during
configuration, ensure RADIUS is configured and running. Otherwise, clients
will not be able to log in. There are several reasons the authentication server
services might be unavailable, here are two typical things to check.

Q Ensure you have the proper RADIUS authentication server information

setup configured in the AP-2000. Check the RADIUS server IP Address
authentication Port number (default is 1812), and Shared Secret.

Q E nsure the RADIUS authentication ser ver RAS setup matches the

AP-2000.

TFTP server

The “TrivialFile Transfer Protocol” server allows youto transfer files acrossa
network. You can upload files from the AP-2000 for backup or copying, and
you can download the files for configuration and AP Image upgrades. The
TFTP software is located on the Agere AP-2000 CD-ROM.

30

Related applications

If a TFTP server is not configured and running, you will not be able to
download and upload images and configuration files to/from the AP-2000.
Remember that the TFTP server does not h ave to be lo cal, so lon g as you
have a valid TFTP IP Address. TFTP does not have to be running for
AP-2000 operations that do not transfer files.

After the TFTP se rver is installed:

Q Check to see that TFTP is configured to poin t to the directory containing

the AP Image.

Q Ensure you hav e the proper TFTP server IP Address, the proper

AP Image file name, and that the TFTP server is connected.

Q Ensure the TFTP server is configured to both send and receive, with no

timeout.
