MODEL 192E OVERVIEW

The ESTeem Model 192E is a IEEE 802.11b
compatible wireless LAN transceiver that
can used to build a Wireless Local Area
Network (WLAN) for line-of-sight
distances to 7 miles for fixed base and
mobile applications. The IEEE 802.11
WLAN was designed to look and feel like
any IEEE 802 wired LAN. The Model 192E
can be configured as a wireless Access
Point to a LAN, Access Point Repeater,
EtherStation Mode (Mobile Client to an
Access Point), or Bridge between wired
LAN’s or Ethernet devices.

MODEL 192E CONFIGURATION
MODES

The Model 192E can be configured for
four modes without any changes to the hardware:

CHAPTER 1

INTRODUCTION

Figure 1: Access Point Mode Diagram

1. Access Point Mode. When the Model 192E is configured as an Access point it will provide a wireless gateway from a

hardwired Local Area Network (LAN) to laptops, office computers, Personal Digital Assistants (PDA’s), video cameras,
PLC’s, etc. that have integral or external 802.11b wireless devices. All Access Points must be physically connected to the
same network (LAN) to provide seamless Ethernet communication for mobile devices.

2. Access Point Repeater Mode. The Access Point Repeater is a unique enhancement of the 802.11b Access Point mode

available only in the ESTeem Model 192E. With this feature, The Model 192E Access Points do not have to be hardwired
together on the same physical LAN to provide seamless Ethernet communication for 802.11b devices, but instead
automatically associate with other Model
192Es programmed with the same
configuration (i.e. SSID, Frequency, WEP,
etc.) for routing message traffic over the
wireless Ethernet network. If there are
multiple routes to a destination, this
feature will create a “self-healing” network
by automatically re-routing data through
an alternate path to reach its destination if
the primary path is inoperable. When
programmed in the Access Point Repeater
mode the Model 192Es will also bridge any
Ethernet network or Ethernet device
connected to the unit over this same
wireless Ethernet network. This mode
gives the user the features of a point to
multi-point bridge network but also allows

802.11b devices or the Model 192E in the
EtherStation mode to access the network.
See Figure 2.

Figure 2: Access Point Repeater Mode Diagram

Revised: 16 Oct 03 1-1 EST P/N AA107

CHAPTER 1

INTRODUCTION

3. EtherStation Mode. This is a special feature of the Model 192E when used in an Access Point application. When the 192E

is configured in the EtherStation Mode and attached to an Ethernet Device, the Model 192E will emulate an 802.11b
PCMCIA wireless card in functionality for communication to an 802.11b Access Point. This mode can provide greatly
increased range over a Wireless LAN Card for mobile Ethernet devices such as vehicles, forklifts, cranes, etc. See Figures 1
and 2.

4. Bridging Mode. The Model 192E can be

used to bridge LAN’s and other devices
with an Ethernet port. In this mode the
ESTeem Model 192E will not accept
requests from 802.11b clients. The two
bridge modes available are Master
Bridge and Client Bridge modes. See
Figure 3.

To begin setup of your wireless Ethernet
network you must first select the type of
Model 192E configuration required. Chapter
2 will show hardware diagrams and the
respective program mode that each 192E
should be configured in for that application.
In each example the respective programming
mode for each Model 192E will be shown
under the ESTeem icon. After you have
designed your network, proceed with specific instructions in Chapters 3 & 4 on how to program the 192E for the mode of
operation needed, i.e. Access Point, EtherStation (Access Client), Master Bridge, or Client Bridge Modes.

Figure 3: Point to Multi-Point Ethernet Bridge Diagram

All possible Ethernet network configurations can not be listed. If your application does not match any of the configurations in
Chapter 2, please consult with your network system administrator or contact EST Customer Support at 509-735-9092.

The ESTeem Model 192E can be configured in six different modes of operation. Chapter 2 shows examples of site diagrams and
the respective mode of operation for each Model 192E to perform its specific task in that example. Listed below are the six
modes of operation:

Ethernet Only. Ethernet Only is a diagnostic mode that allows updates on the ESTeem without activating the transceiver. The
Mode Setup allows the user to change the Model 192E’s Ethernet IP and Ethernet Netmask addresses. See Figure 13.

Figure 13: Ethernet Only Mode Setup Screen

Access Point. Allows the user to configure the Model 192E in the Access Point mode. Reference Chapter 2 Configuration
Diagrams for examples. The SSID is the unique identification for your wireless network. All 802.11b devices that share a wireless
network MUST have the same SSID code. This identification code is case sensitive and must NOT contain spaces. See
Appendix D for information on setting the Channel (Frequency) and Data Rates. See Figure 14.

Figure 14: Access Point Mode Setup Screen

Access Point Repeater Mode. This mode allows the ESTeem to be placed in the Access Point Repeater mode. Reference
Chapter 2 Configuration Diagrams for examples. The Access Point Repeater is a unique enhancement of the 802.11b Access
Point mode available only in the ESTeem Model 192E. When programmed in Access Point Repeater the Model 192Es will bridge
Ethernet network or Ethernet device connected to the unit over the same wireless Ethernet network as the provided for 802.11b
clients.

In an Access Point Repeater network, all Model 192E’s must be configured with the same SSID, WEP codes and be on the same
frequency channel. If there are more than two Model 192E’s connected in the network, one of them should be configured as the
Root Bridge. See Chapter 5 or further information on selecting the Root Bridge.

Figure 15: Access Point Repeater Mode Setup Screen

Master Bridge. Allows the user to configure the Model 192E in the Bridge Master mode. The Bridging Mode is an ESTeem
proprietary network that will not allow 802.11b device to be used in the wireless network. Reference Chapter 2 Configuration
Diagrams for examples. All Model 192E Ethernet Modems that share a wireless network MUST have the same SSID code. This
identification code is case sensitive and must NOT contain spaces. See Appendix D for information on setting the Channel
(Frequency) and Data Rates. See Figure 16.

A value of –1 will disable the auto refresh feature.

RTS Threshold This feature allows the user to specify the size of data packets that require an additional verification

that the remote ESTeem is ready to receive the packet. Packets above the specified value will trigger the
source ESTeem to contact the receiving unit with a request to send (RTS) data packet. When the
destination ESTeem is ready to receive the data packet, the acknowledge to the RTS is sent back to the
source ESTeem. At this time all other units will cease communications and wait until the data packet is
sent before resuming communication. All packets below the RTS Threshold will be sent directly
without the RTS sync. This feature would be used when two or more remote sites are communicating
with each other through a repeater site and are unable to “hear” the transmissions directly. The RTS
Threshold will allow a remote Model 192E to quiet all others users before larger data packets are sent.

Radio Toggle

TX (On/Off). This command allows the user to toggle the transmitter On or Off for measurement of the output power

and SWR testing of the antenna. When the transmitter is toggled On the Model 192E will continue to
transmit until toggled Off.

Remote (On). This command allows the user to toggle the transmitter On for remote measurement of receive signal

strength with a spectrum analyzer. When the remote transmitter is toggled On the Model 192E will
transmit for 20 seconds then turn off. While the transmitter is on, the communication to the modem is
down but will return after the 20 seconds.

Spanning Tree Protocol (STP) (On/Off). Setting the STP to Off disables the ability of the modem to prevent network loops

when configured for Access Point Repeater Mode (see Chapter 5 for further details). It should only be
set to Off in specific applications where the modems need to transmit packets that it normally drops.
For example, Rapid Spanning Tree Protocol (RSTP) packets are dropped by the modem unless STP is
disabled. Networks that need the modems to transmit the RSTP packets must ensure the modems do
not create loops. Two Access Point repeaters connected to the same network via the Ethernet port
would be an example of a network loop.

The ACL is one of the simplest yet most secure methods of network security. The ACL is a configurable MAC filter in the
Model 192E that can be set to allow specific MAC address on the wireless network by individual address or address ranges
(Figure 21). The filter can also be set to reject individual MAC addresses or address ranges (Figure 22). The maximum number
of address that can be entered is 60.

The MAC address is a unique, 6 hexadecimal field address assigned at the manufacturer that can not be changed. The MAC
address is traceable through the IEEE governing body to the manufacturer and is the “fingerprint” for all Ethernet devices.
Using a combination of both the 128-Bit WEP encryption and the ACL filter provide the ESTeem an extremely secure wireless­networking layer.

ACCESS POINT REPEATER MODE

To increase the wireless network area of coverage for
both indoor and outdoor applications with a convential
IEEE 802.11b Access Point (AP) all of the APs have to be
interfaced to a common network either by hardwire, see
Figure 1, or a dedicated point to point RF backbone.

CHAPTER 5

The Model 192E with the Access Point Repeater Feature
allows the user to cover large areas both indoor and outdoor without the added expense of hard cabling or adding an additional
point to point radio link. The Access Point Repeater Mode in the Model 192E is a custom feature offered by ESTeem. When
programed in the AP Repeater Mode, the Model 192E will automatically create a wireless network with other Model 192E units in
radio range that are programmed in AP Repeater mode with a matching configuration. This feature will also add the increased
functionality of repeaters to the typical Ethernet Bridge configuration.

Figure 1: Access Point Diagram

Auto-Routing

One of the most powerful features of the AP
Repeater mode is the Model 192E’s ability to
automatically calculate all possible
communication routes in the network. The
autoroute feature will automatically establish
wireless Ethernet communication paths to each
ESTeem that has a matching configuration. This
automatic routing greatly simplifies network
configuration and also creates a “self healing”
network by sending data on an alternate route if
the primary path fails.

Auto-Routing Process

Listening Phase - Once a modem is configured
for Access Point Repeater mode and reset, the
Model 192E will begin to search out all modems
that have a matching configuration (SSID, Frequency Channel, AP Repeater Mode = ON and WEP Codes). The first step in the
routing process is sending out and listening for “repeater beacons”. A repeater beacon is a special radio packet that is sent
from the Model 192E that contains the ESTeem’s MAC address. When a repeater beacon is received by another Model 192E,
the MAC address of the originating modem is added to its own repeater beacons. A route between two Model 192Es can be
established when they receive a repeater beacon that contains their own address.

Figure 2: AP Repeater Example

As an example let’s look at Figure 2 and the repeater beacons and the route created from Pump Site C and Tank Site B(Repeater).
Pump Site C sends a repeater beacon containing its MAC address over the radio network. The only site that receives this
repeater beacon is Tank Site B (Note – No Line-of-sight (LOS) between from Pump Site C to the other sites in the network).
When Tank Site B receives the repeater beacon it adds the MAC address from Pump Site C to its own repeater beacon and
sends it out. This new repeater beacon from Tank Site B (Now containing Pump Site C’s MAC address) is received at Pump Site
C and a route is established. Pump Site C then adds the MAC address for Tank Site B in its repeater beacon, which is eventually
received by Tank Site B.

Repeater beacons will continually be sent from a Model 192E every 2 seconds as long as it is configured in AP Repeater mode.
This will allow the Model 192E to recognize new sites into the network and any changes to the radio paths. This continued
updates in the repeater beacon give the AP Repeater network the “self-healing” characteristic.

Revised: 16 Oct 03 5-1 EST P/N AA107

CHAPTER 5

ACCESS POINT REPEATER MODE

Learning Phase - When no further routes are added to the repeater beacons in a period of time (approx. 10 seconds), the Model
192E goes into the learning phase. In this phase all Model 192E’s calculate their routes to the other Model 192E’s in the network
using the lowest “path cost” back to the Root Bridge. Note: The Root Bridge in a network should be the Model 192E where
the majority of the data flow is processed. In Figure 2, the Root Bridge will be the Water Plant that is transmitting and receiving
data from all three remote sites. The Root Bridge can be defined by the user, if not defined and there are multiple candidates the
ESTeems in the network will pick the unit with the lowest MAC address. See the following section on Root Bridge for further
details.

Blocking and Forwarding Phase - This last phase in the auto-routing process will eliminate any Ethernet data “loops” that can
double the information received at any remote site. For example, looking at Figure 2, Pump Site D has two routes to the Root
Bridge (Water Plant – Site A); direct from the Water Plant (with a marginal RF link corrected in the following section on using
the ACL in Network Design) and Tank Site B the repeater. The direct link between the two sites is the shortest route (lowest
Path Cost) and will be selected as the primary route (Forward). The longer of the two routes (higher Path Cost) that uses the
repeater will be Blocked. All routes to the Root Bridge will be evaluated and be Forwarded or Blocked. The average time to
complete all routing phases in a network is approximately 30 seconds.

Root Bridge

Any Access Point Repeater application that has more than two sites, needs to set one of the Model 192E’s as the Root Bridge.
The Root Bridge should be the Model 192E where the majority of the Ethernet data flow is processed. This site may be the
Master location in a SCADA network or could be configured at a repeater site. Selection is important because, all the Model
192E’s that are NOT configured as the Root Bridge will select their routing based upon where the Root Bridge is in the network.
If you have any question as to which site in your AP Repeater application should be the Root Bridge, contact ESTeem Customer
Support at 509-735-9092 or e-mail your application to [e-mail] .

The Root Bridge will be selected in one of two ways: the Root Bridge can be manually set (recommended) in the configuration at
AP Repeater mode (Chapter 4 – AP Repeater Configuration) or the Root Bridge will be the lowest MAC address of all the Model
192E’s in the network. It is not advised to allow the Model 192E’s to select the Root Bridge by address, because adding a new
site to the network could adversely change the entire site’s routing.

Using Access Control List (ACL) In Network Design

As mentioned above, the shortest route to the Root Bridge may not be the
best radio path. As seen in Figure 2 the radio path from Pump Site D to the
Water Plant – Site A has a marginal link. Although the shortest route from
Pump Site D to the Water Plant is direct, the best radio path is using the
repeater site at Tank Site B. To force the radio path through the repeater is
as simple as setting the ACL to Deny the communication link to the Water
Plant (see Chapter 4 – Setting ACL for further details). To complete this
operation, set the Deny ACL button (Figure 3) and enter the MAC address
of the Water Plant. The only other possible route to access the Root Bridge
will be through the repeater site at Tank B.

ACCESS POINT REPEATER MODE

Redundant Backup

The ESTeem Model 192E configured in Access Point
Repeater mode will automatically function as a redundant
backup if two Model 192E’s are installed at the same
location (Figure 4). If two Model 192E’s are connected to
the same HUB or Switch, one of the Model 192E’s will be
Blocked when the auto-routing process is completed. The
network will continue to use this route until any problem
with the original Model 192E is detected and the second
Model 192E will begin operation at that site.

Redundant Master Configuration – The configuration in
Figure 4 will also provide a redundant backup for the
Master Site (Root Bridge). Configure both Model 192E’s as
the Root Bridge and the radio with the lowest MAC address
will be the Primary Root Bridge until a problem occurs.

COAXIAL CABLES

Revised: 15 Mar 04 7-1 EST P/N AA107

CHAPTER 7

ANTENNA SETUPS

A 25-ft. length of RG-8 coax cable or 50-ft. length of heliax cable are the minimum cable lengths allowed for use with the above
antennas when the Model 192E is set at Max Power. Listed below are representative cable losses in db/100 ft at the 2.4 GHz
frequency range:

Feedline Type

RG-8 (Solid) 7

LMR 600 4.4
3/8" Heliax 6.5
1/2" Heliax 3.5
7/8" Heliax 2

1.25" Heliax 1.6

In a severe noise environment it may be necessary to use a double shield type of coax cable such as RG -214/U in place of the
RG-8. This cable must be purchased from the factory to meet FCC requirements.

Note: A -3 dB loss means you have lost 1/2 of your signal or transmitter power. A +3 dB gain means you have doubled

(x2) your signal or transmitter power.

Example:

A 6 dB antenna will increase the radiated output power of a 1 watt transmitter to 4 watts {times 4 = 3 dB (x2) + 3 dB
(x2)} and increase the received signal strength to receiver times 4.

Attenuation

(dB/100 ft.) @ 2.4 GHz

WEATHER PROOFING COAX CONNECTIONS

1. Coat the threads of the connectors with silicone lubricant prior to assembly (See Note 1) and hand tighten. Care should be

taken not to get any lubricant on the center conductor.

2. Wrap the connector assembly with a vapor barrier patch for weather proofing (See Note 2), ensuring to overlap onto the

coax cable approximately 1 1/2 inches.

3. Apply an electrical coating (sealing agent) over the vapor barrier patch for added protection (See Note 3).

GROUNDING

All building mount antennas require attachment to a good earth ground for optimum efficiency. Contact a reputable local
communications shop for procedures for your area.

LIGHTNING ARRESTORS

Lightning arrestors should be used on all external building mount antennas for personal protection and to minimize damage to
the transceiver during lightning storms. The units should be installed as per manufacturers instructions provided with the
device.

MEASURING STANDING WAVES (SWR)

A high standing wave ratio (SWR) will reduce the effective radiated power of the radio, reducing the range and potentially
damaging the equipment. Figure 1 shows a block diagram of the equipment configuration for measuring the SWR.

The Fresnel zone shows the ellipsoid spread of the radio waves around the visual line-of-sight after they leave the
antenna (see figure above). This area must be clear of obstructions or the signal strength will be reduced due to
signal blockage. Typically, 20% Fresnel Zone blockage introduces little signal loss to the link. Beyond 40%
blockage, signal loss will become significant. This calculation is based on a flat earth. It does not take into
account the curvature of the earth. It is recommended for RF path links greater than 7 miles to have a microwave
path analysis done that takes the curvature of the earth and the topography of the terrain into account.

(crossover) cable.

Revised: 16 Oct 03 APX C-1 EST P/N AA107

APPENDIX D

RADIO CONFIGURATION

192E FREQUENCY OF OPERATION

In a wireless Ethernet network all of the ESTeem Model 192Es must be set to
the same radio frequency of operation or channel. Listed below is a table
showing the channel and corresponding frequency of operation. The
frequency of operation is selectable when configuring the mode of operation
of the 192E (reference Chapter 4). See Figure 1.

RF COMMUNICATIONS DATA RATE

The RF data rate of the Model 192E can be programmed for operation at 1, 2,

5.5 or 11 Mbps. The RF data rate can be set for a fixed rate or a specific range that is dynamically scaled by the Model 192E

from monitoring the received signal quality. The Model 192E can communicate with multiple 802.11b devices at different data
rates for each device. By selecting all ranges from 1 to 11 Mbps you will be able to communicate with all 802.11b devices
regardless of their generation, data rate, and signal quality requirements.

Note: The first generation 802.11b devices could only communicate at 1 or 2 Mbps depending on the device.

Dynamic scaling means that the Model 192E will operate at the highest RF data rate that is programmed into unit. If the received
data quality drops below the required minimums for reliable communications the Model 192E will reduce the data rate to the next
lowest step to increase signal quality. Conversely if the signal quality increases above the minimums the Model 192E will
increase the RF data rate the next highest level. The factory default is shown in Figure 1.

Channel Number Frequency

1 2412 MHz
2 2417 MHz
3 2422 MHz
4 2427 MHz

6 2437 MHz
7 2442 MHz
8 2447 MHz

9 2452 MHz
10 2457 MHz
11 2462 MHz

The RF Data Rate is programmed in the Model 192E during the mode setup (reference Chapter 4). In the example shown in
Figure 1 the RF Date Rate is programmed to dynamic scale from 1 to 11 Mbps (recommend factory default setting).

RF BASIC RATE

The RF Basic Rate is the synchronization rate

communication rate will be determined by the RF
Communication Data Rate established above.
Factory default is 1 and 2 Mbps shown in Figure
1 so that the unity will establish communication
with the older (slower) 802.11b devices. This
lower rate also allows for a quicker reconnect
when the ESTeems are configured for
EtherStation mode or working in a mobile
environment.

Note: The Model 192E will only communicate
with slower speed devices after synchronization
if the RF Communication Data shown above
has been set to dynamically scale to 1 and 2

RADIO CONFIGURATION

RADIO POWER

The ESTeem Model 192E is adjustable in output power from 100mW to 1 Watt. The output is adjusted on the Additional

Figure 2: Additional Settings Screen

Settings screen (Figure 2) of the ESTeem Web Page interface.

The output power corresponds to the following settings:

Max (Maximum) 1 Watt
Hi (High) 500 mw
Lo (Low) 250 mw
Min (Minimum) 100 mw

To change the default (Max) output power on the Model 192E, select the desired power setting and press the Submit button.
The output power will only be changed after the Apply Changes button is pressed and the modem is re-booted.

TRANSCEIVER CONFIGURATION

Programmed (On/Off). This command will allow the user to program the ESTeem radio transceiver On or Off. This feature

must be saved to be permanent. The normal (default) setting is On.

Toggle (On/Off). This command allows the user to toggle the transceiver On or Off immediately from the setup screen

shown regardless of the programmed setting of the Programmed command. If the unit has been
powered off, the radio transceiver will be turned On or Off dependent on the prior programmed state of
the Programmed command.

Revised: 15 Mar 04 APX D-2 EST P/N AA107

APPENDIX D

RADIO CONFIGURATION

TX (On/Off). This command allows the user to toggle the transmitter On or Off for measurement of the output power

and SWR testing of the antenna. When the transmitter is toggled On the Model 192E will continue to
transmit until toggled Off.

Remote (On). This command allows the user to toggle the transmitter On for remote measurement of receive signal

strength with a spectrum analyzer. When the remote transmitter is toggled On the Model 192E will
transmit for 20 seconds then turn off. While the transmitter is on, the communication to the modem is
down but will return after the 20 seconds.

Spanning Tree Protocol (STP) (On/Off). Setting the STP to Off disables the ability of the modem to prevent network loops

when configured for Access Point Repeater Mode (see Chapter 5 for further details). It should only be
set to Off in specific applications where the modems need to transmit packets that it normally drops.
For example, Rapid Spanning Tree Protocol (RSTP) packets are dropped by the modem unless STP is
disabled. Networks that need the modems to transmit the RSTP packets must ensure the modems do
not create loops. Two Access Point repeaters connected to the same network via the Ethernet port
would be an example of a network loop.

SECURITY

The Model 192E is an 802.11b device and the security of Wi-Fi devices is a popular subject now. This section was written to
address some of the common questions that we are asked. Input on the subject of security is changing daily. EST will
continually upgrade the encryption of its products, as tried and true software upgrades become available for 802.11b users.
Please keep in mind that if 802.11b security is a primary concern, the ESTeem supports a proprietary (non 802.11b) mode with the
Bridge Mode (see Bridge Mode in this section).

What security feature(s) does the Model 192E use?

Currently our production Model 192E uses two, overlapping security layers. The first layer is the latest 128 Wired Equivalent
Privacy (WEP) encryption technique and the second is an Access Control List (ACL). The 128 Bit WEP provides basic security
equivalent to a wired network by protecting the network from unauthorized network traffic monitoring and use. In the ACL you
can specify which Ethernet devices are allowed into the wireless Ethernet network by their MAC address. Every Ethernet
devices in the world has a unique MAC address that is set at the manufacturer and can not be changed.

The 192E can be configured in four major configurations:

1. Access Point Mode.

2. Access Point Repeater Mode.

3. EtherStation Mode (in this mode the 192E can function as a Client to an Access Point).

4. Bridge Mode (point to point and point to multi-point).

According to the researchers, the most vulnerable of the above applications are the Access Point Modes.

128-BIT WEP

The 128 WEP uses a particular algorithm called RC4 encryption to encode and decode traffic that is based on a 104-bit
encryption key and a 24-bit Initialization Vector (IV). RC4 starts with a relatively short encryption key (104 bits) that is
expanded into a nearly infinite stream of keys to accompany the stream of packets.

The basic concept of RC4 is good, but the way it’s implemented in WEP leaves it open to compromise. The researchers that test
the integrity of the system usually focus on one piece of the implementation, the Initialization Vector (IV).

The IV (24 bits) is the algorithm component that’s supposed to keep expanded keys from repeating. From the researcher’s point
of view, a high-volume access point is mathematically guaranteed to reuse the same key stream at least once a day. When this
happens, it’s called an IV collision this becomes a soft spot to enter the system.

The researchers aren’t saying that it’s easy to break into the system, or that it’s being done on a regular basis, only that it is
possible and that administrators should consider ways to reduce the possibility.

ACCESS CONTROL LIST (ACL)

The ACL is one of the simplest yet most secure methods of network security. The ACL is a configurable MAC filter in the
Model 192E that can be set to allow specific MAC address on the wireless network by individual address or address ranges.
The same filter can also be set to reject individual MAC addresses or address ranges.

The MAC address is a unique, 6 hexadecimal field address assigned at the manufacturer that can not be changed. The MAC
address is traceable through the IEEE governing body to the manufacturer and is the “fingerprint” for all Ethernet devices.

Using a combination of both the 128-Bit WEP encryption and the ACL filter provide the ESTeem an extremely secure wireless
networking layer.

SECURITY

ESTEEM BRIDGE MODES

As mentioned above, the most susceptible configurations are those that are compatible with other IEEE 802.11b devices. If the
security level required in your application is greater than what is provided with the 128-bit WEP and ACL, the Model 192E can
be used in a proprietary Bridge Mode. When the ESTeem is programmed for the Bridge mode, it will no longer be compatible
with other 802.11b devices and will not recognize any data transmission from those devices.

INCREASING NETWORK SECURITY

1. Enable the WEP. If you research all of the articles regarding hackers, they have gotten into the user’s network due to the

WEP not being enabled.

2. Set the ACL filter to include only those MAC address of the wireless Ethernet device being used on the network.

3. Set "Hide SSID" to True. As you take your access point out of the box, broadcast SSID is enabled which means that it will

accept any SSID. By hiding the SSID configured in the client must match the SSID of the access point.

4. Make sure the keys are not reused in your company, since reuse increases the statistical likelihood that someone can figure

the key out and change the default password on your access point or wireless router

5. Change the default SSID of your product. Don't change the SSID to reflect your company's main names, divisions, or

products. It just makes you too easy to target.

6. As a network administrator, you should periodically survey your company using a tool like NetStumbler to see if any

"rogue" access points pop up within your company without authorization. All of your hard work to "harden" your wireless
network could be wasted if a rogue AP was plugged into your network behind the firewall.

7. Many access points allow you to control access based on the MAC address of the NIC attempting to associate with it. If

the MAC address of your NIC isn't in the table of the access point, you won't associate with it. And while it's true that there
are ways of spoofing a MAC address that's been sniffed out of the air, it takes an additional level of sophistication to spoof
a MAC address. The downside of deploying MAC address tables is that if you have a lot of access points, maintaining the
tables in each access point could be time consuming. Some higher-end, enterprise-level access points have mechanisms for
updating these tables across multiple access points of the same brand.

8. Consider using an additional level of authentication, such as Remote Access Dailin User Service (RADIUS), before you

permit an association with your access points. While it's not part of the 802.11b standard, a number of companies are
optionally including some provision for RADIUS authentication.

9. If you're deploying a wireless router, think about assigning static IP addresses for your wireless NICs and turn off Dynamic

Host Configuration Protocol (DHCP). If you're using a wireless router and have decided to turn off DHCP, also consider
changing the IP subnet. Many wireless routers default to the 192.168.1.0 network and use 192.168.1.1 as the default router.

10. Don't buy Access Points or NICs that only support 64-bit WEP.

11. Only purchase Access Points that have flashable firmware. There are a number of security enhancements that are being

developed, and you want to be sure that you can upgrade your access point.

12. A simple security technique used by the military is to have the administrator periodically change the key for the system i.e.

weekly, monthly, etc.

TROUBLESHOOTING TIPS

General (Applicable to All Modes of Operation)

Where do I find the latest firmware version number? – We have the latest version number of the Model 192E firmware listed on
the ESTeem Web site (www.esteem.com) under the Model 192E product page.

How and when do I update the Model 192E firmware? - You should only update the Model 192E firmware if you are having a
specific problem and it is recommended that you do so by ESTeem Customer Support personnel. All the update instructions
and files are located on the ESTeem FTP site at the following address:

ftp://www.esteem.com/192E

Do all firmware versions have to be the same to communicate between the Model 192Es? – It is not necessary for all the firmware
versions to be the same revision to communication, but the later version may have features (such as ACL) that the other
versions will not recognize.

What characters are valid for WEP Key entry? - Only the Hexadecimal characters 0-9 and A-F are valid for key entry.

What is the T/E light’s function? – There is no function to the T/E light in the current firmware revision. It will be illuminated
when the Model 192E has power.

What ESTeem Utility version is required to program the Model 192E? – The ESTeem Utility program is not required to program
the Model 192E. The 192E can be programmed using any Terminal Emulation program (such as Windows HyperTerminal) and
any web browser program.

APPENDIX F

TROUBLESHOOTING

What is the speed and duplex configuration on the Model 192E – The Model 192E has a half-duplex 10 Base-T interface that is
compatible with 10 Mbps connections only.

Are the names on the RS-232 menu configuration different than the Web Pages? – Yes. The names on the Web Page are
consistent with all the names listed in the User’s Manual.

Do the Model 192E’s support DHCP? – The Model 192E does not support DHCP, but it will pass the DHCP requests to the
connected devices.

Do the Model 192E’s support Pass Phrase for WEP key entry? – No

I have configured all settings correctly according to the manual, but my ESTeem system will not communicate. What is the most
likely problem? – There are many issues listed in this section that could be the cause of communication problems, but one that is
easily overlooked is settings in the Access Control List (ACL). If you are not using the ACL for limiting client access to the
network, verify that it is configured for “Allow All”. If any other setting is configured on a blank ACL page, the ESTeem will not
communicate with any other ESTeem.

Access Point Mode

Wireless LAN cards are not connecting – Verify that the wireless LAN cards are set to Infrastructure Mode, have a matching
SSID (or ESSIS) set the same as the Model 192E and that all WEP encryption codes are the same.

My Wireless LAN card shows a solid connection, but I can not pass any data – Verify the WEP encryption and the ACL setting
on the Model 192E match the wireless LAN card.

Can I connect to other Model 192E’s in Access Point mode? – No. You will need to configure the Model 192E in Access Point
Repeater Mode.

Access Point Repeater Mode

Repeater Routing Not Going Through Best Radio Paths - If no Root Bridge is set the Access Point Repeater network, the Root
Bridge will default to the lowest MAC address in the network. This site may not be the best radio link to all sites, but will be the
Root Bridge for the network and requires that all wireless data be sent through that site. As a rule, all sites should have at least
one Root Bridge set.

Double Root Bridges in Network - If an Access Point Repeater network has more than one Root Bridge configured, all sites will
link through the lower of the two MAC addresses of the Root Bridge.

Weak or Intermittent Link to a Root Bridge Causing Network Slow Downs – Problems can be seen if a remote location has a
marginal or intermittent communication link directly to the Root Bridge but using a repeater site to the root bridge would provide
a more reliable communication link. The remote will change the routing (up to 30 seconds for complete transfer) from a good
repeater path directly to the Root Bridge any time it receives a single Repeater Beacon from the Root Bridge. The Access
Control List (ACL) can be used to define an exact radio path in the network. To solve the above problem, the MAC address for
the Root Bridge should be placed in the Deny ACL list or only the repeater site’s MAC address should be placed in the Allow
ACL (see Appendix E for complete description).

Wireless Ethernet Traffic is Slow – Make sure the highest traffic node on the network, such as the Model 192E connected to a
building HUB or Switch, is set as the Root Bridge. All wireless Ethernet communication pathways will then be configured to
route data to this site (lowest Path Cost).

How long does it take to re-establish the Wireless Ethernet Network? - If a communication link is lost and the Wireless Network
needs to re-establish the repeater routes, the time can take up to 30 seconds.

APPENDIX F

TROUBLESHOOTING

Should the AP Repeater Mode be used on mobile equipment? - The AP Repeater mode should be used on equipment that will
not change the Repeater Route as it moves. For example, if a mobile device such as a crane can communicate directly to another
ESTeem and will not loose the link in its travel, the AP Repeater Mode could be used. If the device requires two ESTeem Model
192Es (Base and Repeater) to maintain communication across its complete travel, the EtherStation Mode should be used on the
mobile device. The problem will be in the time that the mobile ESTeem will take to transfer between the two sites. In Access
Point Repeater mode the transfer can take up to 30 seconds, while the EtherStation mode will transfer without a packet loss.

Does WEP have to be used? – The WEP does not have to be enabled for the modems to communicate, but all modems must be
configured the same way.

Can the 192E communicate in different mode configurations? – The AP repeater mode is compatible with other 192E’s in AP
repeater mode and Etherstation mode. The Master/Client bridging mode is a proprietary protocol that rejects 802.11b devices
and only communicates with modems configured as Master or Client.

No AP repeater option available? – This option is available in Firmware versions 2.0.2-20.3 and newer. (See Chapter 4, Software
update procedure)

Correct network configuration, but cannot establish communications. – In addition to the network configuration, all 192E
modems configured in the AP mode must share the same SSID and be on the same frequency channel.

Bridge Modes

What is the difference in the configuration menu from the Wireless IP address and the Ethernet IP address? – The best way to
think of the Model 192E in the Bridge mode is that the modem has two separate networks; the physical Ethernet network and the
radio Ethernet network. Each of these networks need to have an IP address for communication, but each one is listed separate
because they need to be configured on separate subnets (see your system administrator for subnet information).

What should the Master Bridge IP Address be set to in the Client Bridge configuration? – This address has to be set to the
Wireless IP address of the Master Bridge.

My status menu shows a solid connection, but I can not pass any data – Verify the WEP encryption and the ACL setting on the
Model 192E are configured the same in the Master and Client Bridges.

Bridge Not Linking – Verify that the Wireless IP and Ethernet IP are one separate Subnets.

How do I set the radio channel in the Client Bridge? – The Client Bridge will search all the available channels to find the Master
Bridge with the correct configuration and does not require a channel be set.

EtherStation

How do I access the Model 192E web page in EtherStation Mode? The Model 192E does not have an active web browser when
configured in EtherStation mode. You must access the ESTeem through the RS-232 port after configuration in this mode.

What IP address do I configure the ESTeem in EtherStation mode? – The Model 192E will not have an IP address in EtherStation
mode.

I can not link my device into the wireless network – Verify that the MAC address of the device is exactly the same as configured
in the Model 192E. The MAC address must have colons between the values.

Can I connect my Model 192E in EtherStation mode to a HUB or Ethernet Switch? – No. The modem must be connected directly
to the Ethernet device for which it is programmed. In EtherStation mode the Model 192E can only service ONE Ethernet device.
