Troubleshooting - D-Link DUB-E100 User Manual

1. Can I use my DUB-E100 on a USB 1.1 port?
The DUB-E100 will work on a USB 1.1 port but the transfer speeds will be limited to the limitations of
USB 1.1. If your computer does not have USB 2.0 ports, you can purchase an add-in USB 2.0 adapter
to add USB 2.0 functionality to your computer.
D-Link offers the following USB 2.0 adapters:
•
DU-520 (5 Port USB 2.0 PCI Adapter) for desktop computers.
•
DUB-A2 (2-Port USB 2.0 PCI Adapter) for desktop computers.
•
DUB-C2 (2-Port USB 2.0 Cardbus Adapter) for laptops computers.
2. Do I need to use a crossover cable or straight-through cable?
With most of D-Link's switches/routers, the Ethernet ports are Auto MDI-II/MDI-X. This means the port
will auto-sense the cable type. Auto MDI-II/MDI-X ports may react differently if the Ethernet cable is not
properly pinned. If you make your own cables, it is very important that they follow the industry standard
pin-out (568A and 568B).
Computer connections to a hub, switch, or router typically use a straight-through cable. When connecting
a computer to another computer or to an uplink port then a cross-over cable is typically required. Rule of
Thumb: "If there is a link light, the cable is right."
3. How do I verify that my DUB-E100 is properly installed?
Windows
You can verify that the adapter has been properly installed in Device Manager:
• Right click on the My Computer icon and select Properties.
• For Windows 98SE and ME: Go to the Device Manager tab.
• For Windows XP, 2000, and Server 2003: Go to the Hardware tab and click on the Device Manager
button

• Expand the Network Adapters heading by clicking on the plus (+) sign next to Network Adapters.
• Right click on the My Computer icon and select Properties.
• The D-Link USB DUB-E100 should appear with a green and gold network adapter symbol.
If the D-Link USB DUB-E100 in device manager appears with a bright yellow exclamation mark or a red x,
please contact D-Link Technical Support.
Mac
1. Click the Apple icon on the task bar, select System Preferences and then click the Network icon.
