Lose Internet Connection After Sleep Mode/Standby/Hibernate

Anonymous

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...

    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.

    I had to CHECK the box in step 5.

    In which case you should be supporting  bizwiz41  (Proposed) Answer.   ; )

    BTW I still think this has nothing to do with IE and the whole discussion could have been moved to a more appropriate forum.

    casoncasa:

    As I posted below, your fix did work for me but I had to CHECK the box in step 5.  Would you mind confirming this setting?  Since you stated "unchecking" several times, I'm guessing it wasn't just a typo.  So I'm curious if perhaps you are using a laptop, whereas I have a desktop machine.  Though I'm not quite certain why that would make a difference.  Perhaps it has to do with the version/brand of the network card or computer's BIOS.

    I believe you are correct regarding how the computer must handle the resume from sleep, and the Reset Network Adapter method does work each time when you resume, but I don't like that option.  The more permanent solution seems to be to check the box, which seems like it would notify Windows and/or Power Management that the device needs to be initialized.
