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...

    Wonderful to know, but it doesn't help me fix the problem. What can I do?

    If "Wake on LAN" is enabled, then the network card _has_ to maintain connectivity when the computer is asleep.

    If "Wake on LAN" is disabled, then the network card can be shutdown and its settings dumped.

    Depending on the driver for your network adapter, the Wake on LAN settings might be on the power management tab for the network adapter in device manager.

    I can reproduce the problem behavior by turning off Wake on LAN.  I vaguely recall tinkering with it a few weeks ago around the time I started to have this problem and I'm very happy to have fixed it.

     

    I will give this a try to see if I can confirm it as well then.

    The "Option 2" BIOS setting above would only refer to Wake On LAN (WOL) functions of the network card, which would allow the COMPUTER to be "awakened" by another PC/console/server on the network.  Most often this is only used in corporate environment settings. Home users 99% of the time will NEVER use this function for anything.

    Again, this BIOS setting only allows the COMPUTER to be "awakened" over the LAN.

    This forum thread is talking about the opposite: Waking the computer and having the LAN not respond.  By all intents listed here WOL would most likely not even work in Vista or Win7, given that the adapter dumps it's settings upon sleep.
