I've had Win7 installed for about 4 days now into a machine consisting of an EVGA 680i SLI mobo, Q9550S, 4G mushkin. Router is a linksys WRT54g and ISP is Comcast with their typical Scientific-Atlanta modem. Previous OS was Vista 32bit.I started seeing this issue after a fresh install then installing the latest Flash player and viewing any flash video. (I've seenothers with similar issues) First time around the video will play fine, but as time goes by and other videos are viewed, the video starts to pause then continue. Plays for ~2-4 seconds then pauses for ~2-4 seconds. It's also at that point I've noticed that it's not just the Flash player but the entirety of my internet connection has greatly decreased in speed. Whether viewing other websites known to be fast at loading or DLing files where I should be getting 700K but only resulting in 40k.Yesterday while perusing these forums, I came across the following settings and figured I'd give them a try: netsh interface tcp set global rss=disabled netsh interface tcp set global autotuninglevel=disabled netsh int ip set global taskoffload=disabled At first it seemed like things were actually a tad faster, but to no avail, the exact same problem creeped up this morning. I did the following:-ran a tracert and ping to a website I visit often showing times exceeding 700ms-I then removed power from the modem for approx 1 minute until the yellow indicator popped up over my network icon, plugged it back in.>it appeared to have cleared the problem, did tracert/ping again seeing times in the low 60ms range>I went back to sites to see if the problem would reoccur, it did.-I did a warm reboot of the system>tracert/ping were back to low times again>went back to various sites again and once again the slow down occurred.-I've since reset the above 3 settings to their default and rebooted, so here I am.When I first experienced the Flash issues I figured it was only that, but soon realized it affected everything. I have not done anything else extensive with the connections such as online games so I don't know if that would cause it or not. Also, this never occurred over the past year with Vista 32 and the only hardware that has changed, was recently, CPU and GPU.At first I figured it was a modem issue as rebooting it cleared, but when I rebooted Win7 and that also cleared it, I ruled it out. One thing I have not done yet, is remove the router from the equation, but I figured I would wait to see what anyone can advise me on.One more thing, the slow down isn't immediate, it's takes about20-30 minutesof viewing Flashfor it start occurring.Thanks for any assitance.

Hi Nunya,try the following commands:netsh interface ipv4 set global reassemblylimit=65507netsh interface ipv4 set global defaultcurhoplimit=64netsh interface ipv4 set global taskoffload=enablednetsh interface ipv4 set global icmpredirects=disablednetsh interface ipv4 set interface interface="the name of ur connection" mtu=1492 currenthoplimit=64 store=persistentnetsh interface tcp set global rss=enabled chimney=enabled congestionprovider=ctcp netdma=enabled ecncapability=enabled timestamps=enabled (thetimestamps is the rest of the line above so dont type it alone)netsh interface tcp set heuristics wsh=enabledand then reboot ur pc and try again ur connection then post the results here!!Give it a try and u will see the diference right awayKind regards,RRPS: also if you know how to deal with windows registry do the following:[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Ipsec]"NoDefaultExempt"=dword:00000001"EnableOffload"=dword:00000001"OperationMode"=dword:00000002"SAIdleTime"=dword:0000012c"CacheSize"=dword:00000400"SAHashSize"=dword:00000800"EventQueueSize"=dword:0000000cso all u need to do is open the notepad and paste the above in it then save as ipsec.reg and change the save as type from .txt to All files,after saving all u need to do is go to the location where u saved it and double click on the ipsec.reg and thats it u all set..

netsh interface ipv4 set interface interface="the name of ur connection" mtu=1492 currenthoplimit=64 store=persistent I am not clear on "the name of ur connection". Is that a name I just make up on the fly or a name that was given to it that I'm not even aware of? The rest of your post I think I can handle.

Is that a name I just make up on the fly or a name that was given to it that I'm not even aware of? The rest of your post I think I can handle. n/m I figured that out..... :P

Kool so then post it here how better ur connection is now ok? i just found out a new feature that i think its by design in windows 7 however its worth a try by using the following:netsh interface ipv4 set interface interface="your connection name" weakhostsend=disabled weakhostreceive=disabled store=persistentnetsh interface ipv6 set interface interface="your connection name" weakhostsend=disabled weakhostreceive=disabled store=persistentfor my things turned out to be even better and hop this helps u too :DKind regards,RR

that registry entry? Win7 won't let me do it because it's not a binary......?

Aww i think then should have a diferent behavior for x64?maybe instead of Dword it must be Qword but i recommend u to wait for experts opine in this case cuz i usex86 system...but i almost forgot u can also apply to the loopback interface the last settings which they look like this :netsh interface ipv4 set interface interface="Loopback Pseudo-Interface 1" weakhostsend=disabled weakhostreceive=disabled store=persistentnetsh interface ipv6 set interface interface="Loopback Pseudo-Interface 1" weakhostsend=disabled weakhostreceive=disabled store=persistentand if u dont know ur loopback interface name just type :netsh interface ipv4 show subinterfaces then look for the loopback name..All my best,RRPS: PLZZZ post the resulttssss i am anxiouss AHHHHH Hehe

Ok if that still didnt work for ya try the following as my last try hehe :netsh interface ipv4 set interface interface="Connection name" basereachable=30000 retransmittime=1000 siteprefixlength=64 store=persistentif that doesnt work then i give up and really dont know how to help u further =/Regards,RR

In regards to your original suggestions, they didn't work! The pausing came back as well as the 700ms ping and tracert. still working on putting these others in.

Aww i think then should have a diferent behavior for x64? maybe instead of Dword it must be Qword but i recommend u to wait for experts opine in this case cuz i usex86 system... but i almost forgot u can also apply to the loopback interface the last settings which they look like this : netsh interface ipv4 set interface interface=" Loopback Pseudo-Interface 1" weakhostsend=disabled weakhostreceive=disabled store=persistent netsh interface ipv6 set interface interface=" Loopback Pseudo-Interface 1" weakhostsend=disabled weakhostreceive=disabled store=persistent got message "The Parameter is incorrect"

Ok if that still didnt work for ya try the following as my last try hehe : netsh interface ipv4 set interface interface="Connection name" basereachable=30000 retransmittime=1000 siteprefixlength=64 store=persistent if that doesnt work then i give up and really dont know how to help u further =/ Regards, RR this command was not found! So the next question is, what are the defaults for everything I just changed?

=/ im sad then hehebut the question about the defaults they are just about the same ,thats by design howver i was wondering if they have changed without ur consentment for some reason...ok lets go by part..MTU if u have a ppp connection the correct value should be set to 1492 coz u carry 8 bytes adicional on the header but if its not the ppp con then the correct should be set to 1500 .now i have some other suggestions if u want to give it a try knowing that u not afraid of trying which is a good virtude and no danger in changing those settings believe me..try these:netsh interface ipv4 set global neighborcachelimit=4096actually just this one...i think it might not make any diference conidering all those settings had no good impact so...im disapointed =/Regards,RR

Ok so facing this cenario the last solution i think is to set the Qos throughput to level 3 and also set the reserved bandwith to 0(default is 20%)...now if u ask me how then i would have to have more time to look for all the policies and then tell ya the paths to achieve that an how to,however if u are using a home premium version the GPO is not available so the only thing to change is the reserved bandwith in the registry...regards,RR

Well I just figured out this what's going on, I just don't know how to fix it! I have a Network Meter in my sidebar, so when viewing flash videos, at some point my throughput maxes out, if I remove any and all internet activity, my throughput remains maxed out. As if I'm still DLing or doing something with my connection. The only way to fix this is to disable my current connection, then enable it to clear it up. So something is locking my up my network(internet) connection and not resetting on it's own when all sources are removed. I played some games online last night and when I got done, though I did not look at the network meter, it didn't seem to affect my connection. ----------------------------------------- Additional information: I repeated the issue and locked my throughput to 6.3Mb down/ ~140K up. it took about 5 minutes for that to occur. While watching my network meter what I saw was this....... while watching Flash vid, the meter would fluctuate between 2.5Mb and 6.5Mb, up down constantly, as I would expect with any connection. (I do have a 12Mb connection) than at about the 5 minute mark the throughput jumps up to 12-14Mb for about 1-2 seconds, then settles on 6.3Mb. This is the point that the meter reading is a straight line. It no longer has the typical peaks and valleys as my through put varies. this is also the point that the vid will start pausing regularly, because supposedly it's locked at 6.3Mb. I also have a mem/cpu usage meter but neither of those are affected. Now at this point I remove/stop all programs that would have access to the internet connection, i.e. browsers, YIM, Steam and it remained at 6.3Mbs, steady line. I opened up the Task Manager to look at the performance area, no part of my system was being accessed, even the task manager network meter was NOT reading any thing significant. NOW, while typing this, the connection appears to have settled down and is no longer locked in, but that took about 5 minutes or more. My next course of action is to do this all again, but this time I'll remove the network meter from the sidebar. Now I don't know if such a small monitoring program can have this affect, but looking to rule it out. ------------------------------------------------------------------------------------------------------------------------- Removing the network meter from the sidebar had no effect.....

Physically swapped from Local Area Connection 2 to 1 with no effect, still happens. So I disabled the unconnected port to see if that has any effect. > No effect, still does it. Something with Flash video just screws my connection and I have to disable/enable to clear it up! ---------------------------------- Just tried disabling hardware acceleration in Flash, no effect! Still locks at 6.3Mb and stays there.

Just checking to see if anyone has any idea?

Hi dude,i recommend u change/create the RWIN value in the network interface via registry in order to Low the latency!Hkey_Local_Machine\System\CurrentControlSet\Services\Tcpip\interfaces\{ur interface GUI}then add a Dword or Qword Value named:RWINdouble click on it and add 34848(decimal not hexadecimal)of course if ur MTU still remains 1492i think finally heres my last shot..PS: if for x64 system u have to create Qword instead of Dword values then consult anyone or google it then apply those changeshope this helps ya

Hi, Please also try the following and see how it works: 1. Update the NIC driver: EVGA Download Drivers Please Note: Since the website is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information. 2. Boot the system to Safe Mode with networking and see how it works: 3. Disable SNP by setting Registry as following: Note: Please perform a full-system backup first. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters] EnableTCPChimney=dword:00000000 EnableTCPA=dword:00000000 EnableRSS=dword:00000000 If the keys don’t exist, please create the keys first. An update to turn off default SNP features is available for Windows Server 2003-based and Small Business Server 2003-based computers Hope this helps. Thanks. Nicholas Li - MSFT

I experiences the same problem you did. It has to do with opening more and more web windows with the10.2 (or earlier) x32 Flash player in them (ie, youtube). Even though you may be running an x64 browser, its running the standards table x32 Flash plugin. And even if you close those windows with Flash in them, your system and browsing starts to really bog down. The fix is to install the beta x64 version of Flash called "Flash Square". Its taken forever for them to finally come out with some kind of x64 version of Flash plugin for browsers. Adobe Flash Player Square Info Page: http://labs.adobe.com/technologies/flashplayer10/square/ Adobe Flash Player Square Download Page: http://labs.adobe.com/downloads/flashplayer10_square.html Direct download link for IE installer (activex): http://download.macromedia.com/pub/labs/flashplayer10/flashplayer10_2_p3_64bit_activex_111710.exe Direct download version for all other browsers (plugins) (Opera, Firefox, Chrome, etc): http://download.macromedia.com/pub/labs/flashplayer10/flashplayer10_2_p3_64bit_plugin_111710.exe I've tested this opening hundreds of windows on an old AMD X2 3800. No bog, and I am now happy with Windows 7. It wasn't Windows 7 fault, it was Adobe Flash plugin. All these posts about changing your network setting parameters, they are irrelevant, these people are talking out their ***.
