Windows 7 drops internet connection, it display Network cable unplugged

    Question

  • i have a laptop MSi gx600 with Windows 7 installed.

    network card: Realtek RTL8168B/8111B Family PCI-E Gigabit Ethernet NIC

    hardware id: PCI\VEN_10EC&DEV_8168&SUBSYS_3FAD1462&REV_01

    driver version: 7.2.1127.2008

    driver date: 14.05.2009

     

    Problem: internet connection drops randomly, usually when load exceed 1MB/s, it display that "Network cable unplugged" but it is plugged in.

    what i tried:

    1.unchecked the box that says Allow the computer to turn off this device to save power on the network card

    2.updated drivers , rollback drivers, official driver from Realtek, from Microsoft..

    3. changed cable/ router

    4. put speed to 10mbit duplex, 100mbit duplex

     

    nothing from what  I tried helped :(

    what i do in order to restore internet connection:

    1. disable internet connection and then enable it.

    2. restart of system.

    3. i wrote a small program in c# that use WMI , which check every 10 sec if internet connection is alive , if it's not it disable/enable internet connection and write the time when it died,

    here what windows log  show what happened during 10 sec window:

    event id:7042

    user:system

    The TCP/IP NetBIOS Helper service was successfully sent a stop control.

     The reason specified was: 0x40030011 [Operating System: Network Connectivity (Planned)]

     Comment: None

     

    event id:7036

    user:n/a

    The TCP/IP NetBIOS Helper service entered the stopped state.

     

    something interesting,maybe not related to my problem but utorrent sometimes don't unload from memory till i don't disable/enable internet connection

  • You're using the latest Realtek driver from this site? 

    http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false  

    If not, give it a shot.  Also, make sure your router's firmware is the most recent.

  • Hi,

     

    Please try:

     

    1.     Press Win + R to open a run box, type: services.msc, press Enter, open Services window, find the “TCP/IP NetBIOS Helper” service, ensure it is enabled and set as Automatic value. Meanwhile, make sure that the dependencies are started.

    2.     Based on my research, the issue can be caused by out dated firmware, please update the BIOS to the latest version so as to support the wireless card functioning correctly.

     

    Best Regards
