802.11g Wireless Gaming Adapter and Ethernet Bridge
Thank you for purchasing the U.S. Robotics 802.11g Wireless Gaming Adapter and
Ethernet Bridge (Model 5430). You can use your 5430 to online game through the
Internet so you can play anyone in the world. Or, you can use the 5430 as an Ethernet
bridge to connect any Ethernet device such as a computer, network printer, or digital
video recorder (DVR) to a wireless router. Finally, your 5430 may also be used to play
your friend in the same house or building provided you each have a gaming console of
the same brand (Xbox-to-Xbox, Playstation-to-Playstation, or other gaming console.

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 connection 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 filtering 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 recommend 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 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.
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 program 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).

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 experiencing 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 connecting 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
