TCP/IP has chosen to restrict the congestion window for several connections due to a network condition.

Why would Windows 8.1 log the following warning message. 

EVENT_TCPIP_TCP_CONNECTIONS_PERF_IMPACTED

TCP/IP has chosen to restrict the congestion window for several connections due to a network condition.  This could be related to a problem in the TCP global or supplemental configuration and will cause  degraded throughput.

I'm seeing this logged very occasionally as a warning in the System Event Log.  Does it indicate something I should consider reconfiguring?  Is it transitory?

As far as I know, I was just using IE11 and listening to Pandora at the time of the most recent message.  Not sure but I don't think I was even watching videos at the time.  A speed test shows I have the full 21 megabit / 48 megabit speeds I'm expecting from our fiber service here.

Hah?  What trouble?  :-)

Hi Noel,
 
Thanks for posting in Microsoft TechNet forums.

I will try to involve someone familiar with this topic to further look at this issue. There might be some time delay. Appreciate your patience.

Thank you for your understanding and support.

December 4th, 2013 1:42am

Thank you, Kate.

Please also, if you have an opportunity, inquire as to what needs to be done to get the Event Log Online Help links at the bottom of the Event Viewer General tab to work properly.  The first click brings this up...

But then, after choosing [ Yes ], one sees only this:

Hi,

please update the NIC driver to the latest version, then monitor it.

Regards,

Mike

December 4th, 2013 10:07am

Hi Mike,

Thanks for your response.

I did a little research...

Since this was a full, clean Windows 8.1 installation from disc, I have been running the driver supplied by Microsoft:

And apparently this is the latest one to go through WHQL certification: 

This is a Dell Precision T5500 workstation, so naturally I checked with Dell to see whether they offer anything newer.  They're only showing drivers up through Windows 7, dated May 2010, as this machine is no longer a current selling model.

My next stop was Broadcom.com, and indeed Broadcom offers a newer Windows 8.1 "NetXtreme" driver on their web site, version 16.2.0.4b dated November 5, 2013.  The 'b' in the name concerns me a bit, as other than this warning my system has been perfectly stable - and for obvious reasons I'd rather not run a beta driver, but the description doesn't actually say anything about "beta"...  I'm a bit undecided as to whether to give it a try.

Is your answer based on known problems seen solved by driver updates - or just general advice along the lines of "if something's wrong it most likely is a driver problem, so take two driver updates and call me in the morning"?

December 4th, 2013 12:49pm

Okay, given that I have a System Image backup and the knowledge of how to roll the driver back to the Microsoft-supplied version if need be, I've gone ahead and installed the Broadcom-supplied 16.2.0.4b version.

It's nice that it didn't require a reboot.

I'll watch the logs and report back...

  

December 4th, 2013 1:18pm

Hi Noel,

you know this error is not common. based on our previous case, the NIC driver may cause it. if you cannot get the latest driver for NIC. please try to reinstall TCP/IP stack.

run the command line in the cmd.exe with admin permission.

netsh int ip reset

reboot the server to take effect.

Regards,

Mike

1.  I did get the driver installed successfully (that's pretty obvious from the version number shown in the dialog above.

2.  I have not seen any additional EVENT_TCPIP_TCP_CONNECTIONS_PERF_IMPACTED events since the installation, nor have I had any network problems.

In this case it looks as though the new driver may well have solved it.  But I'll keep an eye on the logs, as usual, and report back if I see anything else.  I'm marking the suggestion to update the driver as the answer.

Thank you.

   

December 6th, 2013 5:38am

Well, the updated driver ended up not solving the problem.  I got another message logged this evening.  That was before installing today's Windows Updates.

Hi Noel,

i would like to know if you reset the TCP/IP stack with the command netsh int ip reset

Regards,

Mike

December 17th, 2013 11:09am

I hadn't before, but I have just done so.  The command emitted some disturbing lines (and yes, CMD was running with administrative privileges):

C:\TEMP>netsh int ip reset
Resetting Global, OK!
Resetting Interface, OK!
Resetting Unicast Address, OK!
Resetting Neighbor, OK!
Resetting Path, OK!
Resetting , failed.
Access is denied.

Resetting , OK!
Restart the computer to complete this action.

A quick scan of the specific the registry changes shows a few values added and changed, but nothing structurally substantial changed.  I was going to try to list them all here, but your ridiculous forum editor would not cooperate.

Networking functionality seems to be the same.  I will monitor for a recurrence of the error message.

Hello. I've the same exact problem on a Qualcomm network card since the upgrademy computer with Win 8.1. I have no solution now and many times my network is going from 4 mb/s towards 0 b/s. Everytime i reboot it is okay for a variable amount of time. I just changed every piece of my connection except the computer and it do the same thing. The netsh commands says the same thing as above.

I will inquire around the tpip stack. Help from Microsoft would be appreciated, to

1. understand WHY TCPIP do that and stay for hours  even with no traffic at all.

2. what is the PARAMETER on which the user (me) can do something instead of reboot

3. what has changed around this with Win 8.1

Thank's

Interestingly, the last Tcpip warning I got was on January 6.  They had been happening almost every day before that, including several times after the netsh int ip reset.  I can't explain what changed to stop them.  Windows updates didn't go in until January 14.

   

January 27th, 2014 2:10pm

I'm also getting the same issue, at first I thought it was the USB Wireless, but I've now changed to a NIC Realtek... seems to be an OS issue. I'd raise it with Microsoft but lately I've had cases open for months on end with no response so I cant be bothered with them anymore.

I am also starting to think it's a basic OS issue as well. I have upgraded drivers, have excellent hardware (both computer and networking, and I've checked and re-checked settings. The errors still accumulate, about once every few days.  Notably even though the error claims performance will be degraded, I'm not seeing it.  Perhaps they mean "temporarily degraded".

 

June 5th, 2014 4:17am

It has to be OS related.
I have been figtihing this problem for weeks now, no amount of driver updates, different netcards, hardware platforms makes any difference.

I get kicked of my secondary SSID, and default back to my GPO determained SSID. 

I will try and contact intel about this, they migth be able to get some action on this...

After the 4230 Event id, I get quite a few of these.

But I take it that they are just a result of the dropped connection...

I'm sorry to hear you're seeing network problems, Nosfer_tu.

The last of the Tcpip event 4230 warnings I got was 11 days ago.  Before that they would happen about every 2 days - then they just stopped.  It seems coincident with some kind of post-Windows Update cleanup activity, as I see these 29 informational messages in the Setup log just after the last Tcpip error. 

I'm not sure what these are, but it looks like some kind of uninstallation of updates initiated automatically (they were all logged at 2:43 am; I don't believe I initiated anything at that time).

I'll continue to watch for Tcpip warnings, but so far nothing since the 16th.

Now off to figure out what all that cleanup activity was about...

 

June 27th, 2014 12:40pm

So far, I dont belive it is driver, or netcard related, so I totaly agree with your findings that this has to be a MS problem, maybe a "spam" protection setting implemented the wrong way


Thx Noel. I found you post on the other forum, I understand that you belive. That the problem has been solved via KB2964358 ?



I want to initiate this clean up my self in a corperate envirement. Any manual way ?
or just some more info on this auto cleanup thing ?




"
A bit more investigative info...

 The last update "remove" above (KB2964358) describes a security fix to Internet Explorer.  I looked at one of the files (mshtml.dll) which that fix was supposed to bring up to version 11.0.9600.17105.  It's currently at 11.0.9600.17126.  The implication is that this "cleanup" activity isn't affecting current files."

I'm not sure what KB it was that cleaned it up, or whether it was a KB or a follow-up activity from one of the June updates, but I just checked my System Event Log again and I still haven't had any new Tcpip messages.  This is the longest it's gone without such a message since installing Windows 8.1.

And so far my networking is continuing to work fine.

However I think I prefer to fish a little longer without a nibble before proclaiming there to be no more fish in the lake...

FYI, the warning still appears once in a while.

Last one for me was at 9:38 am 2 days ago.  There are no other errors, warnings, or informationals in that time vicinity.

Finally I saw the "TCP/IP" message in the event log, but it looks like there is no solution here.

Thing is, I'm not seeing any specific network problems coincident with these messages.  It's only the presence of the messages that is a bit of an annoyance to me.  I like to run a tight ship.

A secondary annoyance is that something in an operating system can just remain broken (and emitting error messages) ad infinitum.  Aren't there people being paid to fix bugs?  What are these people doing?

Out of curiosity...  Are those of you also seeing these messages running Skype?  Some of the messages are logged at a time when I'm not doing anything (and my system is free of malware).

Same issue here. This is for a Windows 8.1 VM; the driver for the VM is the "Microsoft Hyper-V Network Adapter." That would seem to rule out a 3rd party driver issue, and it looks like this dates back to at least November 2013. Does anyone have a support ticket open on this issue?

I'd settle for a clear description of what they mean by "restricting the congestion window" and what kind of degradation one should expect in terms of actual Internet usage.

This is also a problem with Windows 10 Technical Preview Build 9879.
Final build of windows 10 with a clean install also suffers from this error.

I have this exact problem.

After a reboot (often, but not always) the speed of my wireless Connection is top notch, but after a few minutes in, I get the error and the Connection is running on about 5% of what it should be.

So something is seriously wrong here. Weird Thing is it worked like a charm the first week after I installed Windows 10 (clean install). Then I got an update a day or two ago, and after that I have had this problem.

This is extremely bad and I would hate to revert back to Windows 7 now that I'm set up. Please do prioritize this, as I have also tried all suggestions here With no result.

Yup. After some update a couple of days ago (perhaps it has nothing to do With it) I get this error all the time after reboot, and it cripples my internet speed entirely.

IMMEDIATLY after reboot I launch edge and do a speedtest. It is ca: 45mbps DL and 34-40mbps UL.

Then I get the warnings below (XML).

Just after that I do another speedtest, and it is 0.1-3 mbsp DL and 0.3 - 1  mbps UL. So you can see the difference. Sometimes it spikes up to 20-30 mbps, but the ping varies from 15-30ms.

I had the exact same experience With ISDN, which was fun (15 years ago)..

I started getting this message after upgrading to Windows 10 from Windows 7.   I found it while I was trouble shooting intermittent disconnects from sql database, a problem that didn't exist before the upgrade?  Updating the drivers and a clean install of Windows 10 Pro didn't fix it. Still looking a solution.

"For weeks now I have issues where web pages will load partially and I have to hit CTL+F5 to get the page to load."

I've been troubleshooting this issue on a user's machine for months now.  They either get partially loaded pages, blank IE pages, or flashing windows.  Not malware, I've scanned repeatedly and done manual perusal of processes.

I don't see this issue on other computers connected to the same network switch.  This computer is a slightly different model than the rest, however.   Running latest Intel Proset drivers.  This user uses IE11 mostly, Windows 8.1 64-bit with all hotfixes.  Looking through the event logs, there are scores of these messages in just her system log.

One pattern I can tell is she browses a lot of e-commerce sites, and these issues seem to always occur during her work hours, about once a day.  Try as I might, I can't convince her to use any other browsers to work around the problem.

I'm (still) seeing the same thing, at a lower frequency...
