Hi Amit, Welcome to the Microsoft Community. It would be great if you can answer the following questions: 1. Follow these methods to resolve the issue: Method 1 : First, I would suggest you to refer to the link and try to run the troubleshooter and check if it helps.
How satisfied are you with this reply? Thanks for your feedback, it helps us improve the site. I would still keep an eye out for sales on routers or see if you can borrow one for a few days.
But as long as it is working for now then all is good! I guess im gunna have to try a new router. Has anyone else been having this problem? You still haven't identified the "real" problem so that's why no one has an effective resolution. When I lose an internet connection, here's my troubleshooting path: Actually there's a lot mroe steps, like looking at my cable modem to see if it's connected, etc.
But if I was sitting and my desk and was too lazy to get up. Reboot the router. Reboot the router 3. Check with your ISP for known outages. The yellow triangle indicates that the problem is most likely between the NIC and the router. I would buy a new router ASAP when one goes on sale.
Last edited: Nov 3, I have been checking my ip address, gateway, modem, etc. I can connect to and stay connected to the internet without any problems, but, once in awhile usually when watching a video clip I will get the yellow triangle and everytime this happens its always the same thing, that the default gateway my router is not available. I even tried manually setting the default gateway to my router's ip address and that still didnt help.
It has to be my router either dying or not liking windows 7 for some reason because I have the same modem, router, and network adapter and ive never had this problem before. Oh well, I guess its just time for an upgrade! I had a similar issue in the past and I swapped out the switch and router, but the problem ended up being a bad network card. Once I replaced the offending network card, I put the original router and switch back and everything worked fine. If you have an extra network card lying around, I'd recommend installing it to see if you might have the same problem.
Try disconnecting the router for a while and running the pc directly off the cable modem, that would hopefully help pinpoint the problem.. I see two potential hardware issues Onboard network - other than server boards, onboard network adapters are slow at best, and often fail without complete failure, leading to nearly impossible troubleshooting.
The cat5 cable If it still looses connection, then you know you have a hardware issue. I'd drop back to XP again except that it's a huge hassle. Surely someone has got a fix for this I had trouble with my new laptop Dell and win 7 pro 64 bit , tried for a couple of months to get internet access, it would go from slow to nothing at all, but now and again all would be fine, downloads were left to my other machines as they took ages on the 7 laptop, got rid of IE8 because the pages wouldn't load and started using opera, it certainly improved things but still wasn't right, both my other computers laptop and desktop with xp pro worked fine with no problems at all.
I used all the tricks and work arounds I found on here and the forums on the net, nothing worked, last week I could recieve emails but not send them with the 7 laptop. Still don't know why I did it but, I had a spare wireless router so swapped it, lo and behold, everything now working, even reinstalled IE8 32bit and all is as fast as the xp machines.
The router I was using was a near new Netgear DGN, they have no upgrades for it and it wont run 7! If you have a spare router or can borrow one, try it, there are several routers that wont work properly with win7. The router manufacturers are slowly catching up and writing new software for win 7, but don't hold your breath.
New router didn't help anything here. Neither did bypassing the router completely which my ISP insists you do when you call them for connectivity issues. Once I've rebooted Windows, if I try to open anything that requires an internet connection like Firefox or Outlook before everything loads and my network is up and running, I lose my connection completely and will have to fight with Windows for a while to get a connection to the internet.
It has been a constant fight to keep the connection I do have, as tenuous as it is. Sometimes on reboot it just won't connect to the internet at all. Tuesday, December 29, AM. I have the same problems also. I can perhaps add a bit more information. ETA: I have also checked on the wired connection, and everything seems to work fine with that, so it is definitely related to the wireless connections on the HP Win7 machine. I unchecked this on the network adapter settings for my wireless connection on the Win7 machine, and it appears to have fixed the problem.
Same problem here. I installed W7 64 bit at the weekend to replace Vista 32 bit and had no problems at all until yesterday. I wakened up yesterday morning to find I didn't have a connection - I had to reboot to obtain the connection and once connected, it seemed to last anything between 10 minutes and around 3 hours.
It seems strange but it does seem to be load dependent - I was downloading a fair amount of files yesterday and it did appear that more downloads and bigger files meant a shorter online time. I have a laptop running Vista 32 bit and my wife has a laptop running W7 32 bit. Neither of these computers had any problems with internet connections yesterday. Each time the 64 bit PC disconnected, the other were fine. Hope someone fixes this soon.
Going back to Vista is looking like my best option at the moment. I am also having this problem. I have only loaded Windows onto the machine. They do not have the same issue. They have a consistent connection no drops. The internet drops for maybe 30 seconds at a time then it recovers. The lights on the router show no problems and neither do the other PCs. It is sporadic and quite annoying as I work from home full-time.
The PC is directly connected to the router. I haven't moved my files off my old computer yet because I'm not sure I can work with the internet problem. Tuesday, December 29, PM. Wednesday, December 30, AM. Misery loves company, I guess. Anyone have a drop date on SP2? Hey all. I've narrowed down the issue. Like messinguk said, it's a router issue. I guess not all routers are compatiable with Windows 7. Friday, January 1, AM. For what it is worth, it's difficult to diagnose these problems over the internet so just a few stabs in the dark.
Have you tried turning off the firewall to see if there is a conflict with something? Do you have an antivirus installed or suite installed with its own firewall? If so, I'd can it and try without. There is a conflict with something, what it is I don't know and don't care I'm not a developer, but uninstalling it fixes the problem. Bingo, no more drop out. Do you lose your connection while it is active? Do you lose it under load or light traffic? This little program is a helpful monitor by allowing you to visualize the network connection on your keyboard lights.
Works nicely. There are three new entries in the networking tab. Did you try disabling these and accessing your router? I know that Vista uses these but perhaps the implimentation might be different.
Try it out, got nothing to lose. Might want to try shutting down the QOS as well, try of course one at a time and always leave them off in a cascading sequence until all four are off and see if you have any joy. Good Luck. Did you try switching your cable just for grins or is it wireless. If so, try a cable and see if it works. I am having a similar problem of lost Internet connectivity, and have done some troubleshooting without finding a cure.
New homebuilt PC. Windows 7 Ultimate x64 via TechNet subscription. Windows 7 NIC driver, then latest driver from Marvell.
No difference. IPv6 is disabled in the network configuration. Windows Active Directory domain. Optimum Online cable modem. Static IP address. Most machines have static IP addresses. The router is plugged into a Dell gigabit switch that this new PC and all the wired machines on the network are connected to.
The Windows 7 machine loses Internet connectivity anywhere from about 18 to 24 hours of uptime. A reboot always restores connectivity which lasts a similar number of hours. No other way has been found to restore connectivity. Lost of connectivity is abrupt and is usually first noticed as an inability to browse further in already open browser tabs or resolve sites in new tabs.
AIM and other network-based apps also lose connectivity. That is, I can contact any other machine on the LAN, move files up and back, etc. Once Internet connectivity has dropped, I can still resolve Internet hostnames using nslookup and hitting either of the two local DNS servers. I can resolve by name and ping any machine on the LAN. I can ping the Linksys. I have done a tracert to a a number of Internet hosts and each tracert will continue for a number of hops. I can ping any of those hosts returning IP addresses, but I cannot ping the ultimate destination.
The dropped Internet phenomenon seems to occur regardless of machine load or network load. It is as likely to occur while I am working on the machine as while I am asleep. When this machine loses Internet connectivity, none of the other machines on the LAN do. This is the only Windows 7 machine on the LAN. This is not an issue affecting any other machine. I would be happy to answer any questions and try any reasonable recommendations.
This is my workstation and my principal machine. Thank you. Monday, January 4, AM. Add me to the long list of dittos. This thread describes my situation.
And no solution available yet Wednesday, January 13, AM. Friday evening, five days ago, I opened a case with Microsoft. As of now, five days later, the system is stable and fast, most of those disabled services have been restored, and connectivity has not dropped at all. Wednesday, January 13, PM. I was alerted about the problem yesterday and am in the process of summarizing the failure patterns from multiple threads reporting similar issues and see if we can reproduce the bug.
Meanwhile, if you are still seeing the issue, please run the following commands from an elevated command prompt to gather network traces that can help our team diagnose the issue: It's hard to pin down a re-pro, so I think you should try run the commands once you are in the faulty state.
Netsh trace stop Please send the trace to yu-shun. Thursday, January 14, PM. Friday, January 15, AM. I'm not tech-savvy enough to understand what you're saying, Yu-Shun, but confirm that this is happening to me too. I'm on a Toshiba laptop with Windows 7 and a wireless connection.
Friday, January 15, PM. Aaargh, still not fully awake. Need more coffee. I don't know how to remove that yet, new to the forum stuff. On the netsh command, it just mean you need to specify a complete path for the trace file location. Hi Yu-Shun Wang, i sorted your sleepy error :. Any higher than that for any length of time sees my problem return - my download starts to choke and then die altogether. How did you cap your bandwidth in Win 7? That would be better than not having any stable access to my NAS at all.
Do tell. If it works. Disabled IPv6 under my network adapter properties and all seems to be well now. Streaming DVDs with no hiccups while browsing the internet. As requested, I've sent a trace dump to you via email. And as another data point, when the connection is about to drop, I see a warning message. Saturday, January 16, PM.
I was able to generate a trace using your instructions, above, during the outage. Can I send it to you? I have additional detail to add as well: No only can I ping out and get responses during the outage, but I am able to get streaming market quotes as well. Presumably, quotes are delivered as UDP.
Pings are ICMP. So, perhaps, the problem lies only with TCP? Jeff Newman jnewman at pobox period com. Thursday, January 21, PM. Hi Jeff, Sure. Thanks, yushun. Friday, January 22, AM. Sunday, January 24, PM.
Lockwood 1. Easy as pie to reproduce. Start downloading things via bittorrent - specifically uTorrent 2. Start Steam, start Team Fortress 2 3. Connect to a game The connection will drop very soon, exit the game and verify the NIC connection is toast. Wednesday, January 27, AM. Wednesday, January 27, PM. Been there, done that. Still drops though not as often. Thursday, January 28, AM. I re-enabled "Allow the computer to turn off this device to save power" as well.
This seems to work, could download at sustained 2. Might be worth a try. Disabling "Receive Side Scaling" will likely not affect the average user. Instead of splitting the tcp receive data across multiple cpu cores, it defaults then to using just one core to do all the work.
Folks, Apologize for the slow responses from my part. Especially to those who had sent me your traces. I or someone from my team will analyze the traces for sure. I am just swamped with work recently. Gone through the thread again, and attempting to sort out the patterns of problems because unfortunately, the root causes and resolutions are most likely different for different conditions, even though the common thread is losing Internet connectivity: 1.
Dropping connections when upload traffic is high running some BitTorrent clients, for example 2. No Internet connectivity, but have local connectivity to printer, NAS, home router, etc.
Connection dropping after DNS client resolution failure event 4. Connectivity problems due to wireless routers or Win7 interactions with specific wireless routers 5. Connectivity problems due to IPv6 for those that resolution is to turn off IPv6 6. The list is of course not complete, we haven't got to the fun part like firewall problems, etc. But it's a start. Please take some time to test and identify your specific failure conditions, and send me yu-shun.
Netsh trace stop Thanks, yushun. That goes for my issue anyway, it's clear to me that most of the posts here are not the same issue even though the symptoms are the same losing internet connectivity. For all the proposed answers that i'm unproposing, in case people are wondering, they are all things i already tried. There's always going to be some sort of oddball thing that could cause an issue on a one-off basis, but the basic capability should be stable and robust 'out of the box' without going through ANY of these gyrations.
Thursday, January 28, PM. Can't definitively comment on 1. Is it 'up' or 'down'? Don't know, but it just 'feels' like when a 'load' is put on, the connection will drop. Sunday, January 31, PM. I knew there was a reason I like the Brits Monday, February 1, AM.
I too am experiencing this problem. Though it only appears to be when there is a lot of network activity on Friday it was whilst applying a load of Win updates, and today it was whilst hosting a Video Conference.
IPv6 has been disabled by me. I also have Windows 7 Enterprise running on a Dell Laptop, this is not experiencing the problem. Name resolution for the name dns. Monday, February 1, PM. I have exactly the same problem event , dns servers not responding and I found a slightly older thread that seems to be about the same issue. Tuesday, February 2, PM. Hi You may find this helpful, I have the same problems as many here with connection dropping, I have been using 2 Acers laptops one old one new with w7, 1 ultimate, 1 home both with atheros nic's both wified to the same router, downloading on both with no problems a month then the connections started dropping apparently random with the symptoms of many here Observed 1 one connection may drop while the other computer continues 2 the only change to default setup was power management options unchecked allow computer to turn off device about the time of problems occuring I think 2 may have something to do with it, I am going to change setting back on one computer to test Hope this helps.
Sunday, February 7, AM. Hi guys, my issue appears to have been fixed, but unfortunately i can't say it was due to a hardware or software fault - it seems to have been something on my ISP's end, i just had to phone out 3 different engineers before one would be helpful enough to track the problem down.
I'm not even exactly sure what it was, they spent some time tweaking the junction in my street, but it's alot better now. Good luck to the rest of you. Hi Re MJC 2 above I changed the power management setting back on one laptop but still dropping the same, I'll keep at it though. Sunday, February 7, PM. I am posting this for posterity. I hate when I search the Net, find a thread that applies to a problem I am having and the thread ends without a solution.
I anticipate this will be my last post to this thread. Having that program installed, even when disabled via the tray menu option to do so and a reboot , the machine will drop connectivity in 16 to 22 hours, on average.
With Spyware Doctor removed, the machine is stable for days. I verified this scenario a number of times over the past couple of weeks. I raised the issue with PC Tools, but they are slow to investigate. In the last two weeks, all they've asked me for were the results of a Belarc Advisor run that, I am sure, will tell them nothing.
I have re-installed and will continue to use the free edition of AVG. Thanks to those who made suggestions and offered advice, and thanks to Microsoft Professional Services, who worked with me originally to identify the issue as relating to some piece of installed software. Jeff Newman. Good for you, but that doesn't help me out at all. Still waiting for something out of the trace logs I sent in. Monday, February 8, AM. I had the same problem on my Samsung R with Windows 7 Home Premium bit pre-installed, have Atheros wifi adapter built in.
No connection drops since then. Might work for you if you can get the driver for Windows XP bit to use with Windows 7 bit. Monday, February 8, PM. Thanks, JeffNewman, for all your detailed contributions to this thread and particularly the last one re: Spyware Doctor.
According to Yu-shun above, there seem to be a variety of situations that can cause this dropped connectivity issue. A restart is the only remedy for me. I've sent Yu-shun my traces as he recommended above, but honestly, I don't have much hope.
