Troubleshooting
A network can be simple to install and maintain. However, occasionally something might go wrong.
The best approach to troubleshooting network problems is to start at the very simplest level and
work your way up.
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. Use the steps in Networking Basics to ensure that each computer on your
network has a unique Computer Name and identical Workgroup.
Verify Network Adapter Installation
If your Network Adapters were not properly 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. Select 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 DGE-528T Gigabit Ethernet PCI Adapter branching out after double-clicking Network
adapters.
