HP and Compaq Desktop PCs - Troubleshooting Wired Home Networks (Windows Vista)

This document pertains to HP and Compaq desktop computers with Windows Vista.
This document provides instructions for troubleshooting problems with a wired home network. For assistance with setting up a network, refer to Creating a Wired Home Network and Sharing Files in Windows Vista.

Step 1: Using the network connection checklist

Use the following checklist to solve many problems with home networks:
  • Check all of the network cables and wires. A loose or disconnected cable or wire prevents a network connection and Internet access. Check the following connections :
    • Network cable from the modem to the network hub (or router)
    • Network cable from the network hub to the RJ-45 network port on the computer.
      Figure : Shape of RJ-45 connector
    • Network cable between two computers.
  • Check the lights on the network hub. The lights can often show the location of a connection problem.
  • If you are trying to connect to another computer on the network, make sure the computer is turned on.
    All computers on the network must have network discovery and file sharing set up in order to access the computer and share files over the network. For more information, see Step 2: Using the Network and Sharing Center
  • Check the firewall settings on all the computers on the network. The firewall settings may be preventing network access.
After performing the items in the checklist, try to connect to the network.
If you do not experience problems with the network, you are done.
If you are still experiencing problems with the network, continue with Step 2.

Step 2: Using the Network and Sharing Center

The Network and Sharing Center displays the status of the network and allows you to set up network discovery and file sharing across the network. Follow these steps to use the Network and Sharing Center:
  1. Click Start , Control Panel, Network and Internet, and then click Network and Sharing Center.
    The Network and Sharing Center opens.
    Figure : Network and Sharing Center
  2. Check the status of the network at the top of the window:
    • A double green line between the computer name and the network name indicates a good connection to the network.
      Figure : Good network connection
    • A line with a red X indicates a broken or missing connection.
      Figure : Broken or missing connection
    If the connection is broken or missing, click Connect to a network to attempt a network connection.
  3. The Network area displays the network access and connection.
    Figure : Network area
    Click View status to display the network status.
  4. The Sharing and Discovery area displays the current sharing and network discovery settings.
    Figure : Sharing and Discovery area
    Click the arrow next to each item to change the setting:
    note:
    These settings must be enabled on all computers in order to share across the network. For example, if File sharing is turned off on one of the computers on the network, you cannot access the files on that computer through the network.
    • Network discovery: Turn on network discovery to allow the computer to find other network computers and devices.
    • File sharing: Turn on file sharing to share files and folders with other computers on the network.
    • Public folder sharing: Turn on Public folder sharing to allow other computers access to the Public folder on your computer. You can choose to have owners of other computers on the network to be able to open files, open and modify files, or to deny access to network computers.
    • Printer sharing: Turn on printer sharing to allow network computers access to the printers connected to this computer. Network computers must know the user name and password of an account on this computer to access the printers.
    • Password protected sharing: Turn on password protected sharing to require network users to enter a user name and password of a user account on this computer to access files, folders, and printers over the network. Turn off password protected sharing to allow everyone on the network access to this computer.
    • Media sharing: Turn on media sharing to allow network computers to access shared music, pictures, and videos on this computer.
After configuring the settings in the Network and Sharing Center, try to connect to the network.
If you do not experience problems with the network, you are done.
If you are still experiencing problems with the network, continue with Step 3.

Step 3: Using Windows Network Diagnostics

Windows Network Diagnostics is a tool that identifies many of the problems that can occur with a home network. Follow these steps to use Windows Network Diagnostics:
  1. Click Start , Control Panel, Network and Internet, and then click Network and Sharing Center.
    The Network and Sharing Center opens.
    Figure : Network and Sharing Center
  2. Click Diagnose and Repair.
    Windows Network Diagnostics opens and checks the network for problems.
    Figure : Windows Network Diagnostics
  3. If Windows Network Diagnostics displays a problem with the network, follow the instructions to fix the problem.
    When Windows Network Diagnostics displays the message Windows did not find any problems with your Internet connection, try to connect to the network.
    If you do not experience problems with the network, you are done.
    If you are still experiencing problems with the network, continue with Step 4.

Step 4: Checking the network adapter in Device Manager

If the network is still having problems, there may be an issue with the network adapter. Follow these steps to check the status of the network adapter in Device Manager:
  1. Click Start , right-click Computer, and then click Properties.
    The System window opens.
    Figure : System window
  2. Click Device Manager.
    Device Manager opens.
    Figure : Device Manager
  3. Click the plus sign (+) next to the Network adapters category.
    Figure : Network adapters
  4. Right-click the network adapter, and then click Properties.
    Figure : Right-click menu
    The Properties window opens.
    Figure : Properties window
  5. Under Device status, check to see if the network adapter is working correctly.
    If the network adapter is not working properly, it may need to be replaced. If the network adapter is working properly, the driver may be corrupted.
  6. The driver may be corrupted. Click the Driver tab to update or roll back the driver:
    • Click Update Driver to check for an update to the driver.
      In the window that opens, click Search automatically for updated driver software to automatically scan the computer and the Internet for the latest driver. If an updated driver is available, follow the instructions to update the driver.
    • Click Roll Back Driver to roll back the driver to the previous working version.
Try to connect to the network.
If you do not experience problems with the network, you are done.
If you are still experiencing problems with the network, continue with Step 5.

Step 5: Using Hardware Diagnostic Tools

If you are still experiencing problems with the network, open Hardware Diagnostic Tools to gather more information and respond accordingly.
  1. Click Start , All Programs, PC Help & Tools, and then click Hardware Diagnostic Tools.
  2. If a message displays, click OK to open Hardware Diagnostic Tools.
    Hardware Diagnostic Tools opens.
    Figure : Hardware Diagnostic Tools
  3. Click Communications.
  4. Click Run Test under the network adapter to have Hardware Diagnostic Tools check for problems.
    If an error code is reported, the computer may need to be serviced. Run the test again to confirm the error code. Use the following support document if you need more information about Hardware Diagnostic Tools or you want to look up an error code: Using Hardware Diagnostic Tools to Test for Hardware Problems.
note:
If the steps in this document failed to resolve your issue, you may need to contact support. Use Hardware Diagnostic Tools to help verify hardware failures before calling support or repairing the computer. Use the HP support document Using Hardware Diagnostic Tools to Test for Hardware Problems to learn more about testing for hardware failures. If you receive an error code after running a test, you need to Contact HP (in English) for further assistance. Write the error code number down so that you can provide it to a support agent.
