    No output connection but input connection is normal.


    I have strange network problem these days. I have a desktop PC and installed Windows 8.1. And I have a LAN. The gateway IP address is 192.168.2.1.

    The network works fine when I start the PC. I can access Internet with IE, I can access the config pages of my gateway and I can SSH my local File server. It's a synology ds212j. I assigned static IP address 192.168.2.18 to it and name it as "home_ds". I add dns entry in file "hosts".

    But there will be very strange problems if the PC keeps running about 2/3 days. It seems I can't connect to other computers from my PC. No IE, no SSH, no ftp.... But ping still work. These is no network device listed in my network folder. But I still can access the mapped network drives.

    For example, I can ping www.google.com, I can ping 192.168.2.1 and 192.168.2.18 and "home_ds".

    Approximate round trip times in milli-seconds:
    Minimum = 13ms, Maximum = 61ms, Average = 32ms

    But when I try to telnet and ssh, all failed.
    I tryied:
    telnet www.google.com 80
    telnet 192.168.2.1 80
    telnet 192.168.2.18 22
    all failed.
    I tied putty, msn, outlook,... all failed. But my wife's PC works normally at the same time.

    In the network folder, there should be a list of all my network devices, including my wife's PC and my File server. But it's empty if this problem happens. However I can add them mannually and I can access the network drives.

    And I can connect to my PC from my wife's PC with remote desktop.

    If I logout and login again, the network will recover except 1 new problem. That is I can't access the network drives of my File Server with computer name "home_ds", but IP address works. And I can ping it with computer name.
    K:\>ping home_ds

    A restart will solve both the above 2 problems. But I don't want to restart my PC so frequently.

    I tried to solve this problem by update windows and drivers but failed.

    Update router firmware and see how it goes. Uninstall any 3rd party security. Make sure you actually updated network driver to latest. Uninstall any networking software like VPN, (especially) Hamachi to test.

    The network adapter is Intel 82579V, the driver is 12.10.28.0, which was released on 2013-08-21. It's the latest version I can find.
    I don't use 3rd party security software and no networking software.
