    I've searched through the internet and these forums and haven't been able to find a solution to my problem. If it has been posted and resolved, please direct me in that direction.


    Specs: I have an Asus G74x Laptop with a Windows 7 Home Premium Operating System. I have an Intel(R) Centrino(R) Wireless-N 6150 wireless adapter.

    Problem: Randomly, my connection to the internet is dropped. However, I am still connected to the router. When I troubleshoot the problem with the Windows Troubleshooter, it says the default gateway cannot be found.

    I'll gladly give more information if necessary!

    Thank you,

    Tim

    When you lose internet access does any other device connected to the router still have internet access? If so, is it connected by ethernet? By wireless?

    For when you have internet access and for when it has been lost ...

    Please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector and show ...

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    What do you do to regain internet access?

    When you lose connection please try these tests--in a Command Prompt and you can post the results the same way you did above.

    ping 10.0.1.16 (or whatever your current IPv4 address is)

    ping 10.0.1.1

    ping 8.8.8.8

    ping yahoo.com

    To regain access to the internet, I manually disconnect from my router, and then manually reconnect.

    IPv4 with Internet:
    IPv4 without Internet:
    Ping to 10.0.1.1 with Internet:
    Ping to 10.0.1.1 without Internet:
    Ping to Yahoo.com with Internet:
    Ping to Yahoo.com without Internet:

    Make sure you have the latest wireless driver from your PC manufacturer's web site. If you already have the latest driver reinstall it anyhow in case the installed instance is corrupted.

    What security application(s) (especially firewall or security suite) do you have? I ask because one may be corrupted.

    (From a JohnWill post)

    TCP/IP stack repair options for use with Vista or 7.

    Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

    Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

    Reboot the machine.
