your computer with an IP address. In order for the USR5430 to supply this IP address, you must

insert a pin or paperclip to press the reset button momentarily (less than 2 seconds). This allows

the USR5430 to become a DHCP server capable of serving an IP address of 192.168.1.202 to the

device requesting an IP address. The default IP address of the USR5430 is 192.168.1.201

Accessing the USR5430’s Web User Interface pages

You will need to access the Web User Interface pages for a variety of reasons. The most common

of these is to change from Client Mode to Ad Hoc Mode, to enable security, and to perform a site

survey. Out of the box, the USR5430 is configured in Client Mode. Client Mode converts wireless

data to Ethernet data which is forwarded onto your computer’s Ethernet (NIC) connection. The

easiest way to access the Web User Interface pages is to put the USR5430 in Configuration Mode.

In Configuration Mode, the USR5430 will supply your computer with an IP address.

Follow the steps below to enable the Configuration Mode:

1. Attach the antenna to the back of the USR5430.

2. Plug the AC power adapter into the 12VDC jack on the back of the USR5430.

Performing a Site Survey

Site Survey is a powerful tool and should be utilized to ensure your USR5430 associates to your

wireless network. Performing a Site Survey scans for all wireless routers and access points

within range and displays the SSID (the network names) of each. If you are not associating to

your wireless network or if you are not associating to any wireless network, performing a Site Sur-

vey should be your first course of action. To perform a site survey, follow the steps below:

1. Access the Web User Interface. It is important to verify the status of your USR5430 before

performing a Site Survey. To do so, select the Status tab as demonstrated below:

The network you are associated to will display its SSID name. The MAC address will display

the MAC address of the wireless router or access point. If the SSID name and the MAC

address match those of your wireless router or access point, you are successfully associ-

ated to your wireless network. If the SSID and MAC address to do not match your wireless

router or access point, or if you see a “Device is not associated” message, proceed to Step

R24.0459.00 5430 US Fr Can .book Page 3 Wednesday, February 25, 2004 4:43 PM

2. Select the Tools tab. Click Site Survey. A separate window will appear displaying the SSID

(the network names) of each wireless router and access point within range. Select your

wireless network SSID and click Select.

3. Wait about 15 seconds in order for the device to reboot and click Continue. The Status page

will appear. Your USR5430 should now be associated to your wireless network. If your

USR5430 is not associated to your wireless network, refer to the Troubleshooting section in

this User Guide.

What is Wireless Networking and how does it work?

There are two types of wireless network set ups: Client Mode (infrastructure) and Ad Hoc Mode

(peer-to-peer).

Client Mode is an 802.11 networking framework in which devices communicate with each other by

first going through a wireless router or access point. Wireless devices can communicate with

each other or can communicate with a wired network. Generally, a majority of small businesses

and home users operate in Client Mode because they require access to the wired LAN (usually

from broadband or cable Internet providers) in order to use services such as file servers or print-

ers. The graphic below depicts one example of an Client Mode network using a USR5430 con-

nected to a gaming console.

Ad Hoc (sometimes referred to as peer-to-peer), is a type of wireless network allowing a wireless

adapter or other Ethernet-ready device to connect directly to another wireless adapter or Ether-

net-ready device. The graphic below depicts one example of an ad hoc network.

Wireless Antenna Range Performance

If your USR5430 is not maintaining a wireless connection to your network, you might be encoun-

tering interference from walls or other structures that is lowering your link quality. Try placing

your USR5430 at a higher location, such as a higher shelf, or repositioning it in a different area of

your room or office. You may also be experiencing interference from other wireless devices such

as cordless phones, baby monitors, security alarms, etc. Be sure other wireless devices are on

different non-overlapping channels. It may also be necessary for you to move your USR5430

away from major appliances such as TV’s, refrigerators, microwave ovens, etc. Here’s why:

Wireless antenna’s work off of radio waves. Radio waves don't travel the same distance in all

directions. Walls, doors, elevator shafts, people, and other obstacles offer varying degrees of sig-

nal loss (attenuation), which cause the Radio Frequency (RF) radiation pattern to be irregular and

unpredictable. Attenuation is simply a reduction of signal strength during transmission. Attenua-

tion is registered in decibels (dB), which is ten times the logarithm of the signal power at a partic-

ular input divided by the signal power at an output of a specified medium. For example, an office

wall that changes the propagation of an RF signal from a power level of 200 milliwatts (the input)

to 100 milliwatts (the output) represents 3 dB of attenuation. The following provides some exam-

ples of the attenuation values of common office construction:

• Plasterboard wall: 3dB

• Glass wall with metal frame: 6dB

• Cinder block wall: 4dB

• Office window: 3dB

•Metal door: 6dB

• Metal door in brick wall: 12.4dB

Other factors that will reduce range and affect coverage area include concrete fiberboard walls,

aluminum siding, pipes and electrical wiring, microwave ovens, and cordless phones.

Status Page

The Status page displays the particular status of, amongst other informative details, the network

you’re associated to, including the SSID name, what channel you’re broadcasting on, and what

firmware version your are using.

Note: If the MAC address field displays a “Device not associated” message, this indicates your

USR5430 is not associated to your wireless network. If, however, the MAC address field displays

a valid MAC address, this indicates that your USR5430 is associated to your wireless network.

R24.0459.00 5430 US Fr Can .book Page 5 Wednesday, February 25, 2004 4:43 PM

Wireless Menu Options

Use the Wireless menu to change your mode from Client to Ad Hoc Mode and enter a Network

Name (SSID) or select a unique channel for Ad Hoc Mode. If you are not sure of the SSID of your

network, use the Site Survey feature under Tools to locate a network near the USR5430.

Security: Using a secure wireless network

A wireless network offers you the freedom to roam without the burden of cables but it also means

that your data is accessible to anyone else in range of your wireless grid. If you are concerned

about a neighbor or someone within range of your wireless network using your wireless connec-

tion for malicious activity, we strongly recommend that you enable wireless security to prevent

unauthorized connection or someone from eavesdropping to listen in on your network traffic.

Today, many wireless routers provide several mechanisms for securing a wireless network and it

is recommended that you first enable security on your wireless router and then match the method

you have selected on your clients.

R24.0459.00 5430 US Fr Can .book Page 6 Wednesday, February 25, 2004 4:43 PM

U.S. Robotics recommends any one or both of the following two methods:

WEP (Wired Equivalent Privacy)

Your USR5430 supports 64-bit and 128-bit WEP security. If available on your wireless router, we

recommend you enable the higher bit security. When you enable WEP, it uses a key to encrypt the

data and this specifically formatted data can only be understood by another wireless device that

knows of this key. Since both ends use the same key, any users who do not know the key cannot

connect to your network and use your Internet connection.

MAC Address filtering

Many wireless routers provide a mechanism for creating a list of devices that can participate in

your wireless network. Refer to your wireless router or access point’s documentation to learn if

MAC Address filtering is supported.

Enabling security on your USR5430

Enabling WEP.

After you have obtained your network name (SSID configured on your wireless router or access

point and its security settings), you can use the Security menu located on the Web User Interface

pages to program your USR5430 for WEP security.

If you select WEP, you have the option to enforce Shared Key Authentication (Forced) or let the

USR5430 send it only when a wireless router requests it (Open System).

It is important that you match the Network Keys with those of your wireless routers. If you have

multiple Network Keys, you can enter up to four keys. Note: Network Keys are case sensitive.

When entering a Network Key, be sure you insert the key exactly as it appears in your wireless

router or access point.

Wireless MAC Filtering

You can use MAC Address filtering to connect only to a specific wireless router or access point.

You can add the MAC Address of your wireless router or access point and change the “Wireless

MAC address filtering” field to Allow. In doing so, your USR5430 will only “talk” to your wireless

router or access point and cannot be accessed by other devices.

Radio

Use the Radio menu to enable and disable wireless signal transmission. If you want to shut down

the signal of your unit (disconnect from the wireless network), select Radio Off.

Channel

802.11b and 802.11g use channels to limit interference from other devices. If you are experienc-

ing interference with another 2.4Ghz device such as a baby monitor, security alarm, or cordless

phone, change the channel on your USR5430 as well as your wireless router. The channel feature

will be used mostly in Ad Hoc Mode. In Client Mode, the USR5430 automatically switches the

channel to match the one from the wireless router or access point.

54g Mode

If you are having difficulty connecting to an 802.11b wireless only router, try switching your

USR5430 to 802.11b only mode and do the same with your wireless router. This will ensure you

are connecting to 802.11b devices only. Set the mode to 54g Auto for the widest compatibility.

Set the mode to 54g Performance for the fastest performance among 54g certified equipment.

54g Protection

The 802.11g standards provide a protection method so 802.11g and 802.11b devices can co-exist

in the same network without “speaking” at the same time. Do not disable 54g Protection if there

is a possibility that a 802.11b device may need to use your wireless network. In Auto Mode, the

wireless device will use RTS/CTS to improve 802.11g performance in mixed 802.11g/802.11b net-

works. Turn protection off to maximize 802.11g throughput under most conditions.

54g+ (Xpress)

54g+ is a technology that utilizes standards based on framebursting to achieve higher through-

put. With 54g+ enabled, aggregate throughput (the sum of the individual throughput speeds of

each client on the network) can improve by up to 25% in 802.11g only networks and up to 75% in

mixed networks comprised of 802.11g and 802.11b equipment.

Rate

You may force a lower data rate if you are having trouble getting connected or losing data at a

higher rate. It is important to know that some data rates belong only to one 802.11 standard but

not the other which will force your USR5430 to connect to only that network.

802.11g rates; 6, 9, 12, 18, 24, 36, 48, 54 Mbps

802.11b rates: 1, 2, 5.5, 11 Mbps

Basic Rate Set:

You have the option of supporting all rates as listed in the Rate section above or using the 1, 2

Mbps rates which will support only older 802.11b implementations.

Fragmentation Threshold

This threshold is used to fragment packets which help improve performance in the presence of RF

interference.

RTS Threshold (Request to Send Threshold)

The RTS threshold determines the packet size of a transmission and, through the use of an access

point, helps control traffic flow.

R24.0459.00 5430 US Fr Can .book Page 9 Wednesday, February 25, 2004 4:43 PM

DTIM Interval

The DTIM Interval sets the Wake-up interval for clients in power-saving mode.

Beacon Interval

A beacon is a packet of information that is sent from a connected device to all other devices

where it announces its availability and readiness. A beacon interval is a period of time (sent with

the beacon) before sending the beacon again. The beacon interval may be adjusted in millisec-

onds (ms).

Preamble Type

Preambles are a sequence of binary bits that help the receivers synchronize and ready for receipt

of a data transmission. Some older wireless systems like 802.11b implementation use shorter

preambles. If you are having difficulty connecting to an older 802.11b device, try using a short

preamble. You can select short preamble on if the 54g mode is set to 802.11b Only in the 54g

Mode field.
