Troubleshooting the Hardware Installation
If you experience any problems with the hardware installation, first ascertain that all
network cable connections are firm, that the proper grade of cable is used for the network
connection, and that the cable makeup is correct (straight –– without un-needed
crossovers in the connector wiring). Check that the supporting hub is power-on and
operating normally, and that the hub is properly qualified (under 10Base-T and/or
100Base-TX standards).
Verify Each Computers Identification
If more than one computer on your network has the same “Computer name,”
communications may be negatively affected. Also, each computer must have the same
“Workgroup” name to communicate properly.
Verify Network Adapter Installation
If your Network Adapter were not installed, including the Network System Software or
Device drivers, your network will not function properly. Use these steps to verify that
your Network Adapter are properly installed.
1. Double-Click the “System” icon in the Control Panel.
2. Click the “Device Manager” tab on top of the “System Properties” dialog box.
3. Double-Click “Network Adapters” if you do not see any items branching out. You
should see “D-Link DFE-680TXD CardBus PC Card branching out after double-
Clicking Network Adapters.”
If you do not see any items branching out after double-clicking “Network Adapters,”
your Network Adapter has not been properly installed. Start at the beginning of the guide
and follow these steps for this computer.
If you see symbols such as yellow exclamation point or red “X” over the icon adjacent to
“D-Link DFE-680TX/TXD CardBus PC Card,” your card is not installed properly or may
have a problem. Double-click the “ D-Link DFE-680TX/TXD CardBus PC Card
