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...

    If that works, you probably have a problem with the settings for your network adapter.  Here is my permanent fix

    1)  Click Start -> Search [Device Manager] enter

    1. Expand Network Adapters, and pick the enabled adapter
    2. RIght click and Open the Properties for it
    3. Click on the Power Management Tab.
    4. Uncheck the box for "allow the computer to turn off the device to save power"
    5. Press Ok and you are done

    Thanks. This solved the problem for me (Win 7 Ultimate N x64 - Atheros GigabitEthernet on board).

    I too have a similar issue on a Toshiba Qosmio.  After a few hours I will lose internet access.  My network connecction is still fine, I can connect to networ drives, network printers and remote desktop to other computers, I just lose access to the internet.  This occurs on both my wireless and wired network connection.  The only way I have been able to reestablish connections is to shut down and restart.  I am using Windows 7 64bit ultimate.

    I've been dealing with this same problem for the last two years since I bought my HP Pavilion Elite 64x OS with Vista sp2 installed!  I have tried just about everything but this suggestion, which makes sense.  (I even bought a new router, thinking it was the problem!!)

    I followed your instructions to uncheck the box under power management for my network adapters and hope to God this is the end of this incredibly frustrating problem.

    Thanks, casoncasa for your advice.
