USB Wireless adapter says there is internet connection, but cannot access internet?

A friend of mine has a Netgear USB wireless adapter on their desktop (running Windows XP). The Netgear software says there is a connection to the internet (via her wireless router), and the icon in the bottom right of the screen says there is an internet connection, but when she tries to run Explorer or anything else using the internet, it says there is no connection. There is another computer (with Windows 7) connected to the internet via a direct cable through the router, and it works fine.

Anyone know what the problem could be? Is there a good website that could help me with this problem?

    Your friend may need to reset the TCP/IP stack. The stack handles the communication between a computer and the internet.

    This text is taken from Microsoft's Knowledge Base for "How To reset Internet Protocol (TCP/IP)"

    Use a manual method to reset TCP/IP

    Note This section is intended for advanced computer users. If you are not comfortable with advanced troubleshooting, ask someone for help or contact Support. For information about how to contact Support, see the Microsoft Help and Support contact information Web site: (

    The reset command is available in the IP context of the NetShell utility. Follow these steps to use the reset command to reset TCP/IP manually:

       1. To open a command prompt, click Start and then click Run. Copy and paste (or

       type) the following command in the Open box and then press ENTER:


       2. At the command prompt, copy and paste (or type) the following command and

       then press ENTER:

             netsh int ip reset c:\resetlog.txt

          Note If you do not want to specify a directory path for the log file, use the following


             netsh int ip reset resetlog.txt

       3. Reboot the computer.

    When you run the reset command, it rewrites two registry keys that are used by TCP/IP. This has the same result as removing and reinstalling the protocol. The reset command rewrites the following two registry keys:



    To run the manual command successfully, you must specify a file name for the log, in which the actions that netsh takes will be recorded. When you run the manual command, TCP/IP is reset and the actions that were taken are recorded in the log file, known as resetlog.txt in this article.

    The first example, c:\resetlog.txt, creates a path where the log will reside. The second example, resetlog.txt, creates the log file in the current directory. In either case, if the specified log file already exists, the new log will be appended to the end of the existing file.
