    I have 3 computers on the same modem--one is wireless, other 2 desktop. The one which is having problem is my office desktop. Can't stay online. Have tried many diffrent fixes and cleaned malware, etc to no avail.

    Could someone help me? I am at my wits end and really appreciate all that you can do for me.

    Please show the following for when you are online and for when you are not.

    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.

    You maintain the IP configuration. Using the same techniques as above please show these tests for when "offline."

    ping 192.168.1.31 (or whatever your current IPv4 address is)

    ping 192.168.1.1

    ping 8.8.4.4

    ping yahoo.com

    Those pings show that you have internet access and that DNS is working. So, we need to be more specific. Exactly why do you say "offline"? Because one or more browsers (which one(s)?) fail to load a web page? Some other application cannot access the internet?

    How do you regain the access you've lost?

    What non-Windows security applications do, or did, you have on the machine?

    After about 10 minutes or so online, whatever I am working on, whether it be using Firefox or IE, stops working and when I try to reconnect, the screen says it cannot find a connection. If I am using Firefox, I go to IE and it cannot connect or vice-versa. I try to "diagnose" through that link they give you through IE, but it cannot detect any problems.

    So, I have to restart the computer to get back onto the Internet. Both browsers work at that point-but only for the aforementioned ten minutes.

    My security applications come through Verizon Internet security and they use McAfee. I do not have any others, as far as I know.

    The other two computers do not have this problem.

    Thanks,

    Kristen

    OK, that sounds to me like one of three possible corruptions, with McAfee being the top suspect.

    Uninstall McAfee and run the Removal Tool. You can reinstall it after testing.

    In case the installed driver is corrupted use Device Manager to uninstall the ethernet (right click on it and uninstall is an option); reboot and let Windows discover the adapter and reinstall the driver.

    And, finally, ...

    (From a JohnWill post)

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

    Start, 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.
