    RESOLUTION

    To discover the cause of the problem, follow these steps.

    Back to the top

    Step 1: Make sure the network cable is connected

    Make sure that the network cable is connected to the computer and to the modem. If your computer connects to a hub or to a router, make sure the cable that connects the hub or the router to the modem is connected.

    Back to the top

    Step 2: Make sure that the network adapter is enabled

    1. Click Start, click Run, type ncpa.cpl, and then click OK.

    2. Right-click the Local Area Connection icon. Click Enable if the option is available.

    Back to the top

    Step 3: Reset the modem

    1. Disconnect the cable that goes from the computer to the modem.

    2. Turn off the modem. If the modem does not have a power switch, disconnect the power supply from the modem.

    3. Wait two minutes.

    4. Turn on the modem, and then connect the cable that goes from the computer to the modem.

    Back to the top

    Step 4: Uninstall and then reinstall the modem and the drivers by using Device Manager

    Before you follow these steps, you may have to download the latest driver for your network adapter from the hardware manufacturer. 1. Click Start, click Run, type sysdm.cpl, and then click OK.

    2. Click the Hardware tab, click Device Manager, and then locate Network Adapters.

    3. Expand Network Adapters, and then right-click the icon for your network adapter.

    4. Click Uninstall, and then click OK. In the dialog box that prompts you to remove the files that are associated with this device, click Yes.

    5. Restart the computer. Or, click Action, and then click Scan for hardware changes.

    6. If Windows finds the device but does not recognize it, you must install the latest driver for your network adapter.

    If you have a Realtek 8139 network adapter, updating the driver seems to resolve this issue. For more information, visit the following Realtek Web site:

    Step 5: Create a new DSL or cable connection

    1. Click Start, click Run, type ncpa.cpl, and then click OK.

    2. Click Create a new connection under Network Tasks. Click Next when the wizard starts.

    3. Click Connect to the Internet, and then click Next.

    4. Click Set up my connection manually, and then click Next.

    5. Select Connect using a broadband connection that requires a user name and password, and then click Next.

    6. Follow the remaining steps. Use the connection information from your Internet service provider (ISP) to complete the wizard.

    Step 6: Repair Winsock and TCP/IP

    1. Click Start, click Run, type netsh winsock reset, and then press ENTER.

    2. When the Command Prompt window flashes, restart the computer.

    Warning Programs that access or monitor the Internet, such as antivirus, firewall, or proxy clients, may be negatively affected when you run the netsh winsock reset command. If you have a program that no longer functions correctly after you use this resolution, reinstall the program to restore functionality.

    Back to the top

    Step 7: Temporarily uninstall third-party firewalls

    Some third-party firewall software such as ZoneAlarm and Norton Personal Firewall may cause Internet connectivity issues on computers that are running Windows XP SP2. You may have to temporarily uninstall these programs to test the computer. Disabling these programs may not be sufficient for testing. Make sure that you have the CD or the installation files so that you can reinstall the programs later. If these programs are causing the problem, you may have to contact the program vendor if you need help with the settings for that program.

    Note You may want to verify that the Windows XP firewall is enabled before you remove the third-party firewall program.

    Step 8: Scan for and remove spyware and adware

    We recommend that you install Microsoft Windows Defender. To obtain Windows Defender or to obtain additional information about tools that you can use to remove unwanted software from your computer, visit the following Microsoft Web site:

    http://www.microsoft.com/athome/security/spyware/c... (http://www.microsoft.com/athome/security/spyware/c...

    Back to the top

    Step 9: Clear the temporary Internet files

    1. Start Microsoft Internet Explorer.

    2. Click Tools, and then click Internet Options.

    3. On the General tab, click Delete Files.

    4. Click OK in the Delete Files dialog box, and then click OK.

    internet connectivity errors that give you errors 6XX, are errors that you get when you have dial-up access, bcoz these errors are problems on the phone number or access number or problems with the connectoid.

    If you have a broadband connection (or DSL) you should not encounter any 6XX errors. If you do go to your control panel, open network connections and delete any dial-up connectoids (icons) you have. Also, Click on Start, click Run, type inetcpl.cpl. On the connections tab be sure that you have a dot on 'Never Dial a Connection'

    I just do a system restore - back to a time before the problem, that sorts it out!

    Start Menu - Control Panel - Performance and Maintenance - System Restore is on the left.

    Takes about 3 minutes!
