    I have an intermittent problem with one of my PCs on my wireless home network. While I always have excellent signal strength, most of the time I can not connect to the internet. All the other computers on my wireless network work fine and I can always connect to my neighbors wireless network to get internet access with the problem PC(A dell latitude E6410 with windows 7). When I have no internet access on my network and I run some diagnostics it says that my default gateway is not available. Any suggestions on what might be the issue and how to resolve the issue?

    Welcome to TSG>
    Could be a lot of things.
    Did this ever work ?
    If so what changed?Hardware/software ?>
    May we see:
    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)



    In the command prompt window that opens, type the following command:

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    IPCONFIG /ALL

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

    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.
    Disable encryption on the router.Any difference ?
    May we also see:
    Wifi test exe. Hint from Johnwill

    Download and run Xirrus Wi-Fi Inspecto from
    www.xirrus.com/library/wifitools.php
    on the problem machine. Post a screen shot of the main screen here.



    To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file. To upload it to the forum, open the full reply window and use the Manage Attachments button
    to upload it here.

    Note that this application requires NET Framework to run. If you get an error about a missing function, download and install NET Framework.
