To me it suggests that we might just possibly need a new thread where we can attempt to cross-reference these connectivity issues by indexing the following:
  • Motherboard type and/or NIC chipset(s) having the problem
  • CPU Architecture (x86 or x64)
  • Upgrade or clean install
  • Driver details (i.e. manufacturer and version of driver experiencing connectivity issues)
The reason I am making such a suggestion is because any solution to this kind of problem is likely to be quite different for any given set of hardware and software combinations.

The trends I have observed from this thread are that this dropped connection problem can happen with practically any type of NIC, but occurs more frequently for folks that have performed an upgrade install on a 64-bit Vista machine. Obviously there are just too many variables in play, and this thread has now grown so large that finding those useful nuggets of information that do exist here takes quite a bit of effort, can be easy to miss, and may not apply to your specific configuration.

In my particular case, I replaced the generic Microsoft ethernet drivers for my nForce 680i SLI equipped motherboard with those I obtained directly from the nVidia support site (ethernet driver version 73.14). This has seemed to correct the problems I had previously been experiencing with both of my onboard NICs, and I have not suffered any dropped LAN/Internet connections in nearly a week (other than a brief Comcast broadband outage last Friday, but that was on the ISP side of the equation).

PS - I'd like to add that I have had no such issues on either of the x86 machines I have upgraded, nor the x64 machine on which I performed a clean install.

That sounds like a good idea. I've read as much as I can about the problem but am struggling to fault find it myself as it only happens once or twice a day. It happened a lot more with the release candidate version I was using. I've tried copying large files whilst doing a large file download and it sits there happily doing its thing. My 2 drops yesterday were when I was just doing some light web browsing which confuses the hell out of me! lol

FWIW - I've started a new thread at Ethernet Connection Lost (and Found?)

Not to hijack this one, just an effort to try to build some sort of index/cross-reference that might be easier to search than these 50+ pages are...

My connection doesn't drop randomly, it drops when I try loading multiple tabs that contain a lot of pictures. However, I can download from torrent sites at > 500kb and the connection doesn't drop.

- clean install

Hey everyone,
I registered for this forum just because of this issue which seems to be affecting a lot of people.
I'd noticed that as soon as I upgraded to Windows 7, my internet connection would shut off completely while using any browser. It would happen at random times, at random websites, and usually every 1-2 minutes at least.
I called Microsoft to troubleshoot the issue but they were unable to find any problems, and just went through simple, fruitless procedures.
After calling my ISP, they weren't able to detect any problems on their end either.

The problem?

I disconnected my router and instead tried directly connecting to the modem.
The problem is no longer happening and my connection isn't dropping anymore.

So, to everyone experiencing this problem with Windows 7, I'd say it's more than likely that there's compatibility issues between your router model and this new OS.

My current router is the D-Link WBR-2310, and the problem for me is because of that model.

Hope that helps. Cheers.

Both the W7 installer and W7 update persistently and annoyingly install the wrong driver for my Realtek RTL8111C~RTL8168 ethernet adapter - once this has happened the device packs up completely, perhaps unsurprisingly.

With the right drivers onboard I also notice the hardware power management is preset to allow the OS to turn off the adapter to save energy (if W7 isn't playing nice with this then it could be shutting down the adapter at times when it may be required of course...)

All my losses and drop outs were cured by getting the right driver from the manufacturers website.

I had/have the exact same problem with loosing my LAN connection all the time.
This happened mostly when browsing websites with a lot of pictures/flash on them in different tabs, and I could provoke it to happen by opening loads of tabs.
I disabled the "allow pc to turn off device" and "Device sleep on disconnect" option in the advanced driver tab, and after reading this thread I also disabled "Recieve Side Scaling".
After doing so, I haven't been able to provoke the problem again and so far I have been running with multiple tabs without having any issues what so ever...

Not 100% sure it's gone, but so far it looks good.

eVGA 680i SLI Motherboard
x64 bit CPU
Windows 7 Ultimate x64 clean install
Nvidia Driverversion: 73.1.4.0

Hope this helps, as it seems to have helped me so far...

I'm having exactly the same issue so I've been looking all over the net for possible solutions. I found the below information from another forum. PLEASE NOTE - This post is not by me nor have I had a chance to try it yet but I will do when I get home from work. If it works for anyone please post!

"Do not install your network or motherboard drivers specific to your system!" It seems that the Windows 7 drivers does not get along well with you manufacturer's drivers. Mostly with nvidia based chipsets, which is what I have. I've had Win7 installed since September when the RTM version came out, during that time I noticed connection drop issue when I upgraded my motherboard and nic drivers. I then noticed I would get a random drops in my connection from certain downloads but gaming and everything else worked fine. Since then I did a clean install and the first thing I started was my connection. I downloaded Linux ISOs from DistroWatch.com: Put the fun back into computing. Use Linux, BSD., 6 in total using IE and waited to see how long it would take until my connection dropped. I used Linux ISOs because they were big enough downloads to saturate my bandwidth and would force my connection to drop if a problem existed, you don't have to do what I did to test your download. The test worked fine for a good 5 minutes then I stopped the downloads. Then I installed Firefox and used Downthemall download accelerator plugin and had One 4GB ISO and Three 600MB ISOs. I allowed one ISO to fully download. The others kept downloading as well, but my goal was to see if it could pass one min which it did. One min was around the time when the connection would drop, sometimes it was half a min, so past one minute stable was a good sign. I then installed the nvidia chipset drivers which includes the network drivers and tried the download test again. After a min or less than a min the connection dropped.

I then realized that it was a serious driver issue. What I did to fix this problem is I went into Safe mode using the systems Administrator account ( not the one you make after an install Windows) and uninstall the nic drivers from device manager. To re-enable the Administrator account you have to go into the Manage console using the account you initially created which should have administrator privileges. Don't use the profile that you created with Admin privileges because its not a true admin account, use the system admin account for this process only and disable it again once your done for security reasons.

First you must enter Safe Mode. Safe Mode is for troubleshooting issues within Windows. It disables all servers you are use to while in Windows normally. You can not even connect to the internet unless you chose safe mode with networking. But for this purpose you don't want networking because you want to remove the network adapters. If you were in normal mode this will not work as thoroughly that's why it is best to go into this particular mode. To do this you have to reboot your computer. Once the POST screen comes up ( the first screen showing a logo or a lot of text) Start pressing the F8 key. A menu will appear, select Safe mode then follow the steps below.

Steps for Manage Console

1. Log into your account
2. Right-click on Computer (a.k.a "My Computer")
3. Select Manage
4. When the window appears select "Local Users and Groups"
5. Select the "Users" folder
6. Right-click on "Administrator" account and click properties
7. In properties uncheck the "disable account" option check box then hit apply
8. Close out of manage and log off your account
9. Once at the welcome screen you will notice the "Administrator" account, click it

Steps for removing Nics

1. Right click on "Computer" and select properties
2. On the left hand side of the System info window select "Device Manager"
3. In "Device Manager" go "Network Adapters" and expand it
4. Only select the NIC which is installed on you system e.g( Intel, NVIDIA, or Marvell, etc...)
5. Ignore anything that says WAP or Tunnel as the network device
6. Right-click on your network card's name and select uninstall
7. If you have two NICs on your motherboard uninstall both
8. When they both disappear close out and go back into your admin account while still in safe mode
9. Repeat the previous steps to get back into the management console and "disable the Administrator account"

This account should not be left enabled for security purposes. Worms and trojans usually look for this account if left enabled, disabled when done. At this point reboot your machine, log back in to windows and test your downloads and see if you connection is stable. This is how I solved my problem, this may vary from system to system. This fix is mostly for those who have an nvidia chipset, bare in mind your results may vary also based on your configuration. I have not read up on issues relating to this on Intel or AMD chipsets. If you do have Intel or AMD and are experiencing this problem you can try this solution.

Note: Most of the extra detail is for those who are inexperienced. The experienced techs as well may have looked passed this, so it works out either way. Hope this solves everyone's problems. Please respond with your own findings as well and let me know if my solution worked for you. Lets help one another out.

Also for those who are not very familiar with Windows in general I did this in safe mode being that everything is turned off and when you uninstall the drivers and reboot Windows 7 will re-install them again. You should basically have a connection once you log back in to normal mode


Also, "DO NOT INSTALL THE nForce Forceware Manage software", it causes a lot of Problems you can live without it. Nvidia has some weird drivers and for a while always have. I just stick with updating the video drivers when they update then.
