Network keeps dropping conneciton to the gateway .. troubleshoot how?
PROBLEMAfter ~2 weeks of nearly flawless performance, this machine has developed some sever network-connectivity issues. Every 20-60 min. it looses the connection to the LAN and the network manager reports the "gateway can not be found".SHORT-TERM RESOLUTION:Short-term resolution is to go to the "Network and sharing center" and click "Local Area Connection" or "Local Area Connection 2". Then click "Diagnose", and then "Run these repairs as administrator". I suspect the system is doing little more than a standard "release & renew" but that restores my connection for a few minutes.DETAILS- I frequently run synergy, access shared files hosted on the LAN, and play games online (eg. Entropia Universe) so as soon as the connection drops i notice quickly.- Both networking ports are plugged stright into my SonicWall TZ150 which seems to be working 100% correctly. I'm testing if the problem occures with just one or the other port plugged in .. but so far it seems to be both.- This machine is a dual-boot with WinXP. I was in XP all day yesterday, streaming movies from google, downloading stuff, and running synergy without a problem. Back in Windows7 and it's not working right.Changes just before problems started:- After 12 days of uptime, i powercycled the machine.- Installed the February 1st Windows Update for SilverLight (KB957938)- Installed "Microsoft Updates" - Ran the "Windows7 Beta Platform SDK Configuration Tool" to revert from "v7.0" to "V6.0A" OTHER SYMPTOMS: Right after these changes problems began. I've also notieced a significant increase in harddrive activity .. Juding by the HDD-activity light and the noise, it's accessing the HDD almost continously. It wasn't acting like this when I had iit up for 12 days stright. Not sure if this is realted.AntiVirusWhen I installed Windows7 I followed Microsofts link to get the trial-version of AVG. It is uptodate and has been doing nightly scans without reporting any issues.SystemSun Ultra 40-M2 (purchased last summer)Dual Nxvida nForce 10/100/1000 Mbps Ethernet portsWhats my next step?I'm not sure if this is a bug in the network-stack, a virus or what? Since this is beta it would probably be useful to pin down the real cause of trouble. Does anyone have suggestions of what to try next or how to file a bug report with microsoft?Thanks!

Have you looked in any of the Windows event logs ?Do you leave both network ports active all the time, or just enable one at a time ?Are the ethernet card drivers as current as possible ? (Any problems listed in device manager ?)

HiAfter install of new files windows runs defrag, maybe indexing I do not know but it is "normal" state since vistaIt is possible high disk activity to be caused your problems.Wait to finish disk activity and see how network runs

And I'd forgotten, but I *did* download two copies of a 1.2GB GameEngine source-code project from SVN last weekend. And then started turning the machine off at night... That would explain why the the indexer was running full tilt. Things seemed to improve this afternoon so this might be the answer.If this is indeed the case, a dialog box letting the user know these tasks have to run would be useful. And it should get the hell out of the way when the user is using the machine.

I haven't made any more major file-changes and disk/indexer activity calmed down. However the networking issue persists and is really getting in the way.The Event logs have recorded the error below numerous times. No other computer on the network is experiencing this problem, nor is this machine when it's booted into WinXP. Does not seem to matter if i have one, the other, or both ethernet ports plugged in. If anyone has suggetions of what to try, I would appreciate it!Error from Event Logs:[code]Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address [my mac address].

HiOpen NIC properties see and remember your IPv4 settings - address, mask, gateway, dns servers, and then enter tham manually in IPv4 propertiesIn this way you will set your LAN settings manually.I think problem you found is not related to your issue and can be ignored.

Remove. 1. Click Start. In the Start Search box type "devmgmt.msc" and press Enter.2. Expand "Network Adapters", double-click on the entry of the network adapter.3. Click the tab "Driver", click "Uninstall".4. Click Start. In the Start Search box type "appwiz.cpl" and press Enter. 5. Remove the entries related to the wireless network adapter. Then, reinstall the device driver. If the issue still occurs, temporary disable the anti-virus and firewall. Also I suggest that you upgrade the firmware of your router. If the above suggestions do not resolve the issue, please export the routing table when the issue occurs. 1. When the issue occurs, launch Command Prompt. 2. Enter the following command. route print > %userprofile%\desktop\routeprint.txt 3. On Desktop, open the file routeprint.txt, upload the contents in your post. Additionally, when the issue does not occur, enter ipconfig /all > %userprofile%\desktop\ipconfig.txt in command prompt. On Desktop, open the file ipconfig.txt, upload the contents in your post.

I get the same error, for 3 weeks, i made all. Only this solve my problem.I disable IPV6.. Click Start - search cmd, right-click and choose Run as Administrator. This should launch the command window withe elevated privileges. 2. Run the following command: C:\windows\system32> netsh interface ipv6 set global randomizeidentifiers=disabled At anytime later, you can enable this (if requierd) as follows:C:\windows\system32> netsh interface ipv6 set global randomizeidentifiers=enabled

I have also experienced a similar issues with the beta. I tend to run a clean shop and keep all of my drivers and firmware up to date. The issues for me started within the first hour after the install. Nothing has changed since the upgrade from Vista. While this issue is easy enough to fix on the fly, it is extremely disruptive. I do a lot of work from home and also dabble in on-line games. When it occurs it usually means an immediate disconnect while connected to VPN or any real-time service. For most of the above recommendations I have already tried. As noted, drivers and firmware are up to date. Systems and applications are patched regularly. I have tried killing random services one by one to see if I can find the issue such as firewalls, virus protection and SPAM filters. At this point I have come up blank. My workaround is simple. I keep my device manager up and running and when the issue occurs I disable my NIC and immediately re-enable it. This clears the issue. While the results are almost instantaneous, the damage has already occurred and I am forced to reconnect to my real-time services all over. The one thing which I have not tried yet was to disable the IPv6 which I will do later tonight. Thanks

Thanks to everyone for keeping this thread up to date. I have the same issue with dropping my Internet connection. Nothing I have tried works except to restart my machine. I have notice that this only happens when large amounts of data are being downloaded, especially via iTunes. I will be checking this thread daily to see if anyone has a fix.

(but if problems persist I'll reboot it also).- Checked the plugs. Their fine.- In fact this machine has 2x 10/100/1000 ethernet and problem occures with #1, or #2 or BOTH plugged in. - I have at least 4 computers here working great, including this same one, when I dual-boot it into WinXP. So right now I'm really focused in on the Windows7.- Drivers are a almost year old, but were current when I checked in November. I've also gotten at least 1 Windows7 specific update from nVidia, via Windows-Update. Next Steps:1) reboot router2) disable IPv63) Re-Download Drivers, delete & reinstall them.Other Notes:I was going to do a system-restore because this all started with a windows-update for silverlight of all things (which i have never used...). I would have to go back to ~January 30th .. but i just looked and I only have 4 system-restore points. goinig back to February 9th ... What the hell good is that? Does it just delete them? ...

When it occurs it usually means an immediate disconnect while connected to VPN or any real-time service.Excellent post. I too do alot of real-time and network heavy tasks.I also find this extremely disruptive to my workflow as, even if the network is down <1min. I'm at a standstill, and then have to restart 2 or 3 programs usually. Using:- Synergy- SSH- SVN - LAN FileSharing- Online GamingI too noticed the connection is more likley to drop the moement i start a large file-transfer, or connect to an online-game. etc. The curious thing with my case is that this installation was working fantastic (well .. for windows) and achieved a 12-day uptime before this all started. After that there were some windows-updates and I grabbed a gig of data (sourcecode SDK) from SVN .. but there were no changes that should cause an issue to just startup out of nowhere.

Tried it 2 or 3 times. - Changed speed/duplex back to auto and *kazam* i'm back online.- Forgot to traceroute- Now have IPv6 disabled as per above .. we'll see.==> How do I elevate this as a bug with microsoft? somthing is clearly wrong here.
February 14th, 2009 3:30am

If you cannot dissable jumbo frame set it to lowest value The next step is not to reinstall driver as Arthur Xie suggest you. Do not reinstall driver for now, because problem may be caused by new driver version installed with W7 updates and reinstalling will not solve that problem. If settings I suggested in my previous post does not help, instead to reinstall driver open NIC driver settings following Arthur Xie instructions, and then from driver tab click roll back driver button if it is active

Hi Badacid, I suspect that this is a software compatibility issue. Some programs, such as anti-virus may block IE from receiving data from certain websites is they consider that the websites are not safe. Regarding the Firefox freeze issue, it is different than the IE issue. It is an application hang/crash behavior, and it can be caused by incompatible add-ons, or background programs. I understand that you have backed to Windows Vista. We hope that you will be interesting in testing our next version of Windows 7 beta.Arthur Xie - MSFT

Just to share my experience with this.Using IE 8.0 with 64-bit Windows 7, NVidia network controller wired to LinkSys Router. Like you, I am unable to maintain a reliable network connection. I have several machines running through this router, including Windows XP Pro, Ubuntu Linux 8, Windows Vista (32-bit), and Mac's Leopard 10.5. Only the Windows 7 box cannot maintain a reliable network connection. Before upgrade from Vista 64-bit to Windows 7 64-bit, this box had no network connection issues. I call this a network connection issue because the Network Diagnostics (from control panel) shows a failure in the connection from my box to my router. Because my only network use is internet connectivity, I see the problem as lost internet access. When this happens on my Windows 7 box, I check all my other machines. None of them ever lost internet access.I can force the issue at will by viewingflash presentations. The failure happens between 29 seconds and 2:19 seconds into a presentation. It also loses connectivity when trying to dowload and install browser add-ons from sites like Adobe. I did turn off the IPv6. It made no difference for me.I am running the commercial version of AVG and plan to turn of the resident shield and try again, just to see if all the tracking cookies are causing the problem. In addition, I will take your advice and check the router settings for security to see if I have DoS enabled or not.I haven't tried this with other browsers like FireFox, yet. your friend in Houston, Texas, Dr. Dave

Well it appears as if I have finally solved the problem on my computer. I originally went through Dells website to download what I thought was the most recent driver update for my network adapter. But just for the heck of it, in Device Manager I right clicked on my wireless driver and selected Update Driver Software..sure enough it found an update and installed it. Now things seem to be going peachy. I just downloaded a 100MB TV show from itunes in a little over 10min without problem or a network drop and still going strong. The driver I updated was: Dell Wireless 1395 WLAN Mini-Card Maybe this solution can work for others.

Ok, sorry all, i've been WAY too busy to continue following up on this. I learned not to use that computer for streaming network-data in Win-7, it's only a $3,000 SUN, what the ____ right?... Anyways last night I set up to run a movie-presentation post-production and rendering task, batch operation of five projects, that was supposed to take about 12 hours, and I needed it for today. Was supposed to be saving to the storage server sitting next to it. Well that was just too much "streaming data" and when the net-connection dropped it was unable to save the first part and the thing canceled. As someone once requested here's some files a took at one point and forgot to post. I've tried most/all of the solutions in this forum one at a time, and nothing has made a difference. I can't find any evidence of a software incompatibility. I've used two different virus-scanners, and tried it with none at all. I use multiple web-browsers, as well as other applications to stream net data.

i have the same problem i am running win7 rc7100 on the media pc everything is going fine untill a 2 or 3 weeks ago if i do something network heavy like transfering a large file or watching hdtv on the xbox360 using media center the network comes up with a connection error . if you do a ipconfig it still has ip address and gateway unplugging the network cable has no affect i used to power the machine off and on which would fix it but if i go to network connections and disable then enable the network connection that fixes it so atm im thinking its a driver issue apart from that im really happy with win 7 so far

Don't know if this thread is still and in living volor but here it goes;Same problem as everyone else, so I'll cut to the meat -Got a VAIO desktop with an Intel PRO/1000 PM network adapter on the motherboard.Driver, driver, who's got the right driver?Ended up right where I started, the INTEL site; http://downloadcenter.intel.com/Product_Filter.aspx?ProductID=3019&lang=englooking at my choices, none of which were Windows 7.Finally decided to go for 'OS Independent', which took me to a 139mb file called Intel(R) Ethernet Drivers and Software for Multiple Operating Systemsv14.3Downloaded it (Release 14.3 Retail_196239.zip) and extracted it. While it was extracting, caught a glimpse of Win7-32 and Win7-64, amongst everything else!Got my hopes up and ran the Autorun.exe that came with it.......................................................................................Worked like a champ! Am now surfing and downloading as if it were an XP machine!No more, 'Disable', 'Enable', 'Disable', 'Enable'.Life is good again even with Windows 7 Build 7201.Hope this helps someone. Seems like we have to wait for the vendors to get their drivers updated and out there, hopefully by October!Ciao all.

Hi Ive been having exact;y the same problems that almost all you guys have been posting about, when downloading large files then trying to stream some video at the same time or when using voip applications my network would drop and I could only resolve this by disabling and re-enabling my network adapter, after a lot of time spent poking around in the dark I seem to have found a resolution (for myself anyway) so far my connection has been stable under load for over an hour when previously it would drop within 5-10 minutes of it being under load, I found that by disabling recieve side scaling on my network adapter and disabling tcp auto tuning within windows 7 seems to resolve the issue.to disable tcp auto tuning:-goto start and in the search box type cmd then hold ctrl + shift and hit enter to start it in admin mode, type the following.... netsh interface tcp set global autotuning=disabled then hit enter the folling line should say ok indicating it disabled successfully.to disable RSS (recieve side scaling) :-I went into network and sharing centre via control panel then clicked change adapter settings from there I right clicked my network connection and selected properties, then clicked the configure button and then clicked the advanced tab, I had an entry in here for my network card for recieve side scaling which was set to enable, I disabled this and hit ok, just to be on the safe side I then went back into the command promt as described in the steps for disabling tcp auto tuning and run the following command:-netsh interface tcp set global rss=disabledthe following line should say ok indicating it disabled successfully, then I restarted my system and all seems to be working fine now!oh I forgot to mention im running win 7 build 7100 4gb ramevga nforce 680i sli premium mobousing nvidia onboard net adapter on 680i sli chipsetThis fix worked for me and I hope it helps some of you, I know personally I spent many hours stressing over this issue.RegardsStu

This is really helpful Ever heard something of DHCP? How come you suggest to enter MANUALLY and IPv4 address? I suggest Microsoft stops using their paying clients as beta testers for banana software

I suggest Microsoft stops using their paying clients as beta testers for banana software Your comment is really helpful and positive too, this was a free and open beta when this thread was opened. If you were looking for an answer to a problem concerning your connection you could prossibly look at the normal Microsoft Windows 7 pages as these threads specifically address problems occurring during the Beta - LC versions. Some time and development has passed since then.
