Gigabit USB Adapter
Chapter 1: Introduction
Welcome
Thank you for choosing the Gigabit USB Adapter. This Gigabit USB Adapter will allow you to network better than
ever.
How does the Gigabit USB Adapter do all of this? An Gigabit USB Adapter allows you to connect to any 10/
100Mbps or Gigabit hub or switch without having to open your PC. The Gigabit USB Network Adapter from Linksys
allows you to instantly connect to a network from a USB-enabled desktop or notebook PC running Windows
Millennium, 2000, or XP. The Plug-and-Play compatible device attaches to your PC’s USB port via a USB Type A
connector. Simply connect a standard UTP Category 5 network cable into the Gigabit USB Network Adapter’s RJ-
45 port, install the included network software driver, and you are networked.
The Gigabit USB Network Adapter is bus-powered, drawing power from the host PC and requires no external
power cords. The Adapter features the maximum throughput supported by USB, easy-to-read LEDs, and compact
design.
Use the instructions in this Guide to help you connect the Gigabit USB Adapter, set it up, and configure it to bridge
your different networks. These instructions should be all you need to get the most out of the Gigabit USB Adapter.

Appendix A: Troubleshooting
Common Problems and Solutions
Gigabit USB Adapter
Appendix A: Troubleshooting
This appendix consists of two parts: “Common Problems and Solutions” and “Frequently Asked Questions.” This
appendix provides solutions to problems that may occur during the installation and operation of this product.
Read the description below to solve your problems. If you can't find an answer here, check the Linksys website at
www.linksys.com.
Common Problems and Solutions
1. Windows doesn't detect new hardware with the Gigabit USB Network Adapter hardware connected,
or it continues to detect the adapter each time I restart the PC.
• You might not have correctly or securely installed the adapter into your computer. Check that the adapter
is securely inserted into the appropriate USB Port.
• The system BIOS might not be USB compatible, your PC’s USB settings may not be enabled, or the
motherboard may have USB options not supported by Windows Millennium, Windows 2000, or Windows
XP. If you are not sure, contact your PC’s manufacturer.
• Refer to the PC’s User Guide.
2. Windows can't locate the driver for the Gigabit USB Adapter
• You may have inserted the wrong Driver CD into your PCs CD-Rom drive.
• The Driver CD may be defective or files may be missing, or you may be pointing Windows to the wrong
drive. Ensure that the driver CD includes the files “USB1000.inf” and “USB1000.sys”.
3. The Windows Logon screen doesn't appear after restarting the computer.
• Click on Start, then Log Off. Log back in. If this doesn't solve the problem, your PCs manufacturer may
have disabled Windows' networking. Contact your computer's manufacturer for help. If using Windows
2000, refer to your Microsoft documentation.
4. On the Access Control Tab, User Level Access is selected, but Shared Level Access is grayed out and
not accessible.
• You previously had your primary network logon set to Client for NetWare Networks. On the Configuration
tab of the Network Properties window, ensure that your primary network logon is set to Client for
Microsoft Networks.
• Your personal web server PC or Microsoft Front Page may require you to choose a user level for security
reasons.

5. In Network Neighborhood I can see myself but no other computers.
• Make sure that the cables are connected correctly. Make sure you are getting Link or Activity lights on
both the Gigabit USB Adapter and your hub if you are using one. Try changing to a new cable that you
know is working.
• Make sure that the other PC is turned on.
6. I’ve decided that I don’t want to share a drive or printer anymore, or I have decided to physically
remove a drive or printer from my network.
• You’re going to have to manually reconfigure your File and Printer Sharing settings. To do so, double-click
on your My Computer icon. Click on the Printers folder. A window of available printers will appear. Using
your right mouse button, click once on the printer that you want to disable on the network. Click on
Sharing, followed by the Sharing tab. Click on Not Shared. When you're done, click on the Apply button,
followed by OK.
• You can disable shared drives in the same way. In Windows Explorer, right-click on the drive you want to
stop sharing. Click on Sharing, followed by the Sharing tab. Click on Not Shared. When you're done,
click on the Apply button, followed by OK.
7. In Network Neighborhood, I can only see some of the computers.
• Choose Start, Find, Computer and type the name of the computer in the window that comes up and click
Find Now.
• Now make sure that you are using the same protocol(s) and workgroup name on all other computers. To
do this, click Start, Settings, Control Panel on two computers running different Windows operating
systems. Click on the Network icon, choose the Configuration tab, then click on the Identification tab for
Workgroup name. Compare the protocols on both computers and make sure that they are the same. If
any protocols are missing, refer to Windows Help.
• Ensure that File & Print sharing is enabled on every computer.
8. Network Neighborhood is empty.
• Verify that your Microsoft Client is installed. See the Windows 98 setup instructions in this guide for
directions.
• Verify that you have logged in correctly. Refresh the screen by pressing F5 several times.
9. On some notebook PCs, the Gigabit USB Adapter fails to configure correctly after the drivers have
been loaded.
After loading the software drivers, it may be necessary to do the following:
1. Log off and unplug the device from your PC’s USB port.
2. Turn off your PC.
3. Plug the device back in and reboot.
4. Log on after the PC reboots.
