Using the Reset Button

You may use the reset button to restore your 5430 to factory defaults. Place the 5430 into a special

configuration mode or just reboot the device.

•Firmly press the button and release under 5 seconds to reboot the 5430.

•Firmly press the button less than 5 seconds for Configuration Mode.

•Firmly press the button for more than 10 seonds to restore to factory settings.

Using the reset button to enable the 5430’s DHCP Server

If you need to access the 5430’s Web User Interface pages, you will need to have the 5430 supply

your computer with an IP Address. In order for the 5430 to supply this IP Address, you must hold

the reset button for more than 5 seconds. This allows the 5430 to become a DHCP server capable

of serving an IP Address in the range of 192.168.2.2 - 192.168.2.254 to any device requesting an IP

Address.

Accessing the 5430’s Web User Interface pages

Out of the box, the 5430 is configured in Client Mode. Client Mode converts wireless data to

Ethernet data which is forwarded onto your computer’s Ethernet (NIC) connection. Since the

5430 is in Client Mode, it is acting as a pass-through device and as a pass-through device, you

cannot access the Web User Interface pages until the 5430 is placed into a Configuration Mode.

In Configuration Mode, the 5430 will supply your computer with an IP Address.

To enable the Configuration Mode, firmly press the reset button between 5 and 10 seconds with a

pen or paperclip. When the reset button is released, the 5430 will reboot into Configuration

Mode and is ready to provide your computer with an IP Address.

After allowing sufficient time (approx. 2 minutes) for the 5430 to reboot, you can test whether

your computer has an IP Address from the 5430 by launching an Internet browser and typing

192.168.2.1 in the address line. If your search for the device times-out or you did not get a dialog

box for the username and password, you may need to refresh the IP settings on your computer.

Follow the steps below for your operating system to refresh the IP settings on your computer.

Once complete, access the 5430 using your browser.

Windows 95, 98, or Me Users:

Click Windows Start and then Run. Type winipcfg and click OK. Check the IP Address, Subnet

Mask, Default Gateway, and DNS server data to make sure they are correct. If the information is

not correct, click Release All and then click Renew All.

Windows NT, 2000, or XP Users:

Click Windows Start and then Run. Type cmd and click OK. At the DOS prompt, type

ipconfig /all. Check the IP Address, Subnet Mask, Default Gateway, and DNS server data to make

sure they are correct. If the information is not correct, type

ipconfig /release and press Enter. Then, type ipconfig /renew and press Enter.

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 aneighbor 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.

U.S. Robotics recommends any one or a combination of the following three methods:

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’s documentation to learn if MAC Address fil-

tering is supported and how to enable it. You will need to

WEP (Wired Equivalent Privacy)

Your 5430 supports 64-bit and 128-bit WEP security. If available on your wireless router, we rec-

ommend you enable the higher bit security. When you enable WEP, it uses a key generated by the

wireless device to hid (encrypt) the data and this specifically formatted data can only be under-

stood 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.

Enabling security on your 5430

I want to enable WEP.

After you have obtained your network name (SSID configured on your wireless router and its

security settings, you can use the Security menu located on the Web User Interface pages to pro-

gram your 5430 for WEP or WPA security.

Your 5430 provides both WPA and WEP security features (refer to the What is the difference

between WPA and WEP? section in this User Guide for additional information).

When Network Authentication is Disabled (No WPA), you need to make a choice whether to leave

Data Encryption Off (No security) or select WEP (The network key you enter will determine which

strength encryption to use: 64- or 128-bit).

R24.0451.00 5430 English Install.fm Page 3 Wednesday, February 4, 2004 5:20 PM

If you choose to leave Data Encryption off, you do not need to do anything else but click Apply to

confirm your choice. If you select WEP, you have the option to enforce Shared Key Authentication

(Forced) or let the 5430 send it only when a wireless router requests it.

It is recommended that you match the Network Keys with that of your wireless routers. If you

have multiple Network Keys, you can enter up to four keys.

Advance Menu Options

Radio

Use the Advance Menu to enable and disable frequency transmissions; Radio On or Off.

Channel

802.11b and 802.11g use channels to limit interferance 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 5430 as well as your wireless router.

54g Mode

If you are having difficulty connecting to an 802.11b wireless only router, try switching your 5430

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

necting to 802.11b devices only.

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.

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 5430 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

R24.0451.00 5430 English Install.fm Page 5 Wednesday, February 4, 2004 5:20 PM

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.

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.

54g+ Xpress

Xpress is a proprietary technology that allows two devices using this technology to connect at

speeds greater than the standard 54Mbps rate.

User Interface pages in this User Guide for more information). Launch an Internet browser and

enter http://192.168.1.201 in the address line. Enter the username (the default username is

admin) and the password (the default password is admin) to access the Tools menu. Browse the

directory where the downloaded firmware file was placed and start the upgrade. It is important

that you do no unplug the cable or interrupt the upgrade. Allow several minutes for the adapter

to reboot after the upgrade.

R24.0451.00 5430 English Install.fm Page 7 Wednesday, February 4, 2004 5:20 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 an unsecured network near the 5430.

Tools Menu Options

Site Survey will search for all unsecured (No WEP or WPA enabled) networks (SSID) in range of

the adapter and allow you to select one for association.

Use the Tools menu to change the 5430 login account, modify the 5430’s IP address, configure

the DHCP servers’ settings and restore the 5430 to factory defaults.

Troubleshooting

I am experiencing poor link quality in some areas of my home or office.

Possible Solution:

You might be encountering interference from walls or other structures that is lowering your link

quality. Try placing your 5430 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 wire-

less devices such as cordless phones, baby monitors, security alarms, etc. You may need to make

sure other wireless devices are not being used while you are using your network.

Possible Solution:

Try changing channels on both your 5430 and your wireless router. For more information regard-

ing the use of channels, refer to your wireless router’s documentation. To change and select the

channel of your choice, access the Web User Interface by opening an Internet browser and enter-

ing http://192.168.1.201 in the address field. Select Wireless from the Menu bar. Select the cor-

responding channel from the Channel pull-down menu and click Save. Be sure the channel

selected on your 5430 matches the channel on your wireless router.

I am unable to access the 5430’s Web User Interface pages.

Possible Solution:

To access the Web User Interface pages, you must put the 5430 in Configuration Mode. To do so,

insert a pin or paperclip to press the reset button less than 5 seconds. The reset button is located

on the back of the 5430. Open an Internet browser and enter http://192.168.1.201

Possible Solution:

Verify that the power light is blue. If the power light is not blue, verify your AC power adapter is

properly connected and that your Ethernet cable is properly connected as well.

How can I tell what network I’m associated to?

Possible Solution:

To determine what network you’re associated to, access the Web User Interface by opening an

Internet browser and entering http://192.168.1.201 in the address field. Select Client mode and

click Next. The settings of the network you are associated to will appear. These settings must

match the settings of your wireless router. Refer to the wireless router’s documentation to check

your network settings.
