Lose Internet Connection After Sleep Mode/Standby/Hibernate

I recently purchased a new HP Pavilion Elite e9105z CTO Desktop and migrated from Win XP to Vista Home Premium x64, with a NVIDIA nForce 10/100 Mbps Ethernet Controller.  Whenever I come out of sleep- or standby-mode, I lose my Internet connection and have to either reboot my system or run the Windows Network Diagnostics to repair the network adapter settings.

I have tried several remedies available from the Internet; but unfortunately, nothing has resulted in a permanent solution.  I contacted my ISP provider (Mediacom) to ask if there was/is an issue with the firmware used to support my SBV5220 cable modem (e.g., non-compatibility with Vista) and they said there isn't.  To date, I've:

  1. Reinstalled network card driver.
  2. Checked and reset power options with USB CDC.
  3. Applied update for Windows Vista (Default Gateway Setting is Lost ) for x64-based Systems (KB933872)--received response that update does not apply to system.
  4. Reset IP configuration via Cmd line.
  5. Under the Power Management tab, unchecked the box that turns off the adapter when power saving kicks in.

I access the computer several times a day and having to reset Internet connections has become extremely aggravating.  I hope there is a solution.  Thank you in advance for your assistance.

Returning from a 3-week vacation, during which my desktop was off, my local internet connection would no longer come active when it came out of hibernation.  The wireless functioned, but the local connection would not work unless I physically unplugged the cable from the router (Netgear) and reinserted it.

After several days of frustration I went into Device Manager, unchecked the  ethernet adapter option "allow the computer to turn off this device".

This seems to have cleared up the problem, at least so far...

    Savan H - I appreciate your post in an effort to help.  But as I said in my initial post, I tried installing the fix from KB933872 and received a response that it was not applicable to my system.  I really don't know where to go from here.

    Tried your suggestion; but unfortunately the condition remains the same.

    Hi,

    Try this out.

    After you wake a Windows Vista-based computer from sleep or from hibernation, the network icon in the notification area does not show the correct connectivity status :

    Hello,

           Welcome to Microsoft Vista Answers Forum!

    In addition to the information provided, please take a look at the link below for more information concerning why you lose Internet Connection after sleep mode.

    http://support.microsoft.com/kb/933872

    After you wake the computer from sleep, the DHCP Client service (Dhcpcsvc.dll) is responsible for informing the IP stack about the routing information. The routing information is stored in the network store interface. This problem occurs when the network store interface already has the routing information that the DHCP Client service wants to store. When the storage operation fails, all routing information in NSI is lost. Therefore, the computer loses all the routing information. This includes the default gateway.

    <quotes>

    The English version of this hotfix has the file attributes (or later file attributes) that are listed in the following table.

    Dhcpcmonitor.dll  6.0.6000.20554 10,240  10-Mar-2007  02:47  x86

    </quotes>

    I have Vista SP2 and I can't tell if this hotfix is included in it or regressed in at least dhcpmonitor.dll.

    <cmd_output  OS="VistaSP2">

    C:\Windows\System32>g:filever dhcp*.dll

            c:\windows\system32\dhcpcmonitor.dll

    --a-- W32i   DLL ENU  6.0.6000.16386 shp     10,240 11-02-2006 dhcpcmonitor.dll

            c:\windows\system32\dhcpcsvc.dll

    --a-- W32i   DLL ENU  6.0.6002.18005 shp    204,288 04-11-2009 dhcpcsvc.dll

    </cmd_output>

    Was the reported change to  dhcpcmonitor.dll  essential to the operation of this hotfix?

    TIA

    Robert
