Random network connection loss

• Satellite L300 PSLBGE network connection drops randomly times

  Hey,.

  I had this problem with my laptop because I bought 1.5 years ago.
  Now I launch Windows 7 x 64 with the latest bios (version 2.20 - WIN; day 25/02/10), chipset and wireless (the card is a: Realtek Wireless LAN Adapter 8187 B; driver version: 62.1182.0331.2010) drivers.

  The problem is that my network connection drop at random times.
  This produces both with my wireless lan card and it comes up with a variety of routers (at work and at home I use a linksys wrt54gl, but I tried it on all the other routers with the same result).

  I don't think it's a hardware failure, since the network seems to work very well under Linux (I tried Ubuntu 10). Also some time I took it for warranty service and they said that the material is fine, but I should "not use many programs at the same time and use Windowx XP.

  I understand the different devices (card WiFi, network card, webcam, etc.) inside the laptop are connected to some kind of usb hub. My guess is that it is something wrong with this "hub", given that the webcam works as defective.

  Thank you

  > From what I understand the different devices (card WiFi, network card, webcam, etc.) inside the laptop are connected to some kind of usb hub. My guess is that it is something wrong with this "hub", given that the webcam works as defective.

  No, the card WLan and LAN card are not connected to the USB just the webcam interfaces so it cannot be any USB issue.

  I think it might be a problem of Windows since Linux is OK

  I think you should check the power management settings in Windows 7 and card Wlan /LAN. This can be done in the Manager of devices-> WLan / LAN card-> Advanced tab properties.

  I also recommend upgrading from win 7 to the last installation of State all updates and patches

• I lose the internet connection randomly but never lose my wireless network connection.

  I use a hp pavilion dv9500 with 64-bit vista sp2 and built in a wireless adapter that will fall randomly my internet wireless connection, but maintains my wireless network connection with an excellent signal strength.

  My (non-permanent) fixed
  I know how to reconnect to the internet, but it forces me to diagnose a repair my connection. It then displays "cannot connect to Server primary dns (75.75.75.75)"after which it gives "things to try" who never work and a button 'Reset the ip address' that I click. " repair bar will fill up to half way and go to a new screen solution that shows more 'solutions' and a "reset wireless adapter" button which I click. the remedy bar will fill and then display windows can not solve the problem and go for help. I then manually disconnect from the wireless network and my computer will automatically reconnect to the network and to the internet. It takes about five minutes to fix, but it happens so often that it is getting boring. The process will not work if I only to reset the ip address and then disconnect from the network, only to reset the wireless adapter and then disconnect, or just disconnect from the network and reconnect. I have to reset the ip address and the wireless adapter and then disconnect from the network.

  The internet connection will tend to disconnect when I watch a lot of youtube videos, when I download large files like a game on steam, or just just randomly when I use it. I'll use it for a long time and he can't let it go, but sometimes it will go down to ten minutes after I had just reconnected in a drop-down list. It happens randomly without another warning that download time will increase from 2 mb to 50 k in two seconds all about or stop the loading of a youtube video when I look at it.

  I searched everywhere for an answer, but it's as if it were a new problem for all humanity or just im the only person who does not know how to solve this problem, because there are no forums or FAQ not related to my problem. It is not so much a serious problem such as an irritating problem that appears at inconvenient times or when I just want to relax and watch a video. It takes some time to reconnect and even though I know how it would be better if my connection would just stay connected to the internet at any time.

  I have no idea what the problem could be that whenever I have find I never get related problems. all advice or solution would be great.

  I also share this modem with other three commonly used computers: a wired office and two other laptops that the two are connected wirelessly. both other laptops do not have the same problem as mine. My router is a linksys e3000 wireless router.

• Drops network connection randomly, error message in Event Viewer ' TCP/IP NetBIOS Helper service was successfully sent a stop command, error code: 0 x 40030011.

  Original title: network Drops randomly: the TCP/IP NetBIOS Helper service was successfully sent a stop control

  The given reason was: 0 x 40030011 [OS: network connectivity (planned)]

  I want a definitive answer for this! For some reason any that never seems to have been resolved. I'm on a Samsung qx410 computer J01 laptop with windows 7. The wireless adapter is an Intel Centrino Advanced - N 6250 AGN. I've tried making it so the adapters could not be disabled for reasons and basically all of the steps for this energy saving. I did everything with the drivers and software. In the event log, it has this event where he falls TCP/IP NetBIOS support apparently without reason? I then immediately lose my connection and it never seems to happen with the rhyme or reason. Any suggestions? It doesn't seem to be a hardware problem either. Where is microsoft on this topic? It seems to be a Windows 7 problem...

• Pavilion dv6-7135nr: loss of network connectivity and wireless after upgrade to Windows 10 cable

  After the upgrade to Windows 10, I lose network connectivity after a restart of the computer.

  The operating system fails to load drivers Broadcom 4313 n. The driver date is May 8 202. The reason code is 31 on failure to load the drivers.

  I returned to Windows 7 and migrated to Windows 10 several times with the same result. I tried to upgrade on the Broadcom drivers, but Windows says they are up-to-date.

  I also see that the Realtek PCIe GBE Family Controller is having the same problem.

  I think it's a driver problem, but cannot find the correct set of drivers.

  Any help would be very useful. I have just re-upgrade to Windows 10 and have network connectivity.

• Printer all in one, loss of network connection

  I have a Photosmart HP 5510.  This is only about a year, but is now always lose the network connection.  I configured correctly (it actually worked!) to the wireless router.  Most of the time now when I need to print, it tells me that the printer will not communicate with the computer.  I took it out of the network, put it back on, and he said: it is connected.  I have not printed the network status page, everything is OK, no problems found.  So I'm still not able to print? It's very frustrating.

  I set it up to my Macbook Pro and my iPad.  He has worked on both devices, but I can't seem to get it back in shape now.

  I have looked on the forum here and have seen many many people with the same problem, but most seem to be using a Windows operating system.  Any ideas on what to do?  I really need to print!

  I did reset the router that worked. It happens every few weeks for some unknown reason. I'm in. fiber.

• Loss of wireless network connection

  Have a WRT160N router (Wireless-N), which works well for months.  Suddenly, although I can see the network connection Wireless 2.4 GHz as being available, I can not connect.  Someone knows why reason?  Appreciate any comment / orientation.

  Thanks for the comments.  I tried to re - adjust, but I think you're right in that it was a problem with channels - too much interference from other devices in the House. All good now.

• Network connection out our off during periods of inactivity, loss of internet connection

  Vista prem 64 houses a dell studio xps 435mt, methinks periodicly lose my internet connection.  This is is produced several times during a download of 200-song itunes where pops up a message saying download failed to expire my network connection.  I also noticed that I have initially no network connection when I use my computer after a period of inactivity.  the network in my tray icon will have a red x through it to a connection restored after that I "wake up" my computer with the mouse.  It's particularly frustrating during downloads large/long because they get sometimes completely removed.  my power management is set to 'performance' and my monitor is the only thing that stops after inactivity.  everything else is set to always run.

  my computer is connected to a satellite modem (wild blue) through a linksys wrt54g wireless router.  the firmware on my router, as well as the driver for my network card ARE up-to-date.

  I read on the network cards with power management options where you can uncheck a box to disable the ability of the computer to reduce power to the / network card.  When I go to the tab power management on the config of my network card, so I have not this box...

  someone knows what could happen?

  Hi oakono,

  Here is a screenshot of what David is trying to show you.  Please make sure you on the same page.  Also check more on Lan box to avoid that the computer goes into sleep or Hibernate mode when you still download.

• Implementation of the LACP Protocol in vDS without loss of network connectivity

  Hello

  Situation: a 2 node Cluster esx with a vDS with 4 physical uplinks. VDS has 4 trade (management, 2 for vmotion
  (and a PG for the vm network).

  What are best practices to implement LACP without interruption to network connectivity?

  I read about some problems remove some uplinks to an existing vDS. If someone does this?

  Best

  Alex

  Here is a video I created using LACP with the VDS 5.1.

  Configuration of LACP on a vSphere 5.1 Distributed Switch - YouTube

  Like I said before, any time delete you an uplink it there is a risk of disruption of the network. You then create new distributed port groups that are needed.

  High level:

  1. Create new VDS
  2. Remove 2 uplinks from the former VDS (chance to drop ping)
  3. Add 2 uplinks to the new VDS
  4. Configure LACP on the new physical ports and VDS
  5. Create groups of port required on the new VDS
  6. Migrate virtual machines (chance to drop ping)

• Photon: Dropped calls and network connectivity problems

  I bought my Photon August 18 and he was not long for me first to the problems with network connectivity.

  The phone displays signal on the phone, but when you try to call, send text messages or surf the web. Zilch.

  A soft reset works every time. I've had some experience with the issue of the "appeal of ghosts", but had no network connectivity so often that he was too much a problem. Restores the soft 3-4 per day.

  I took the phone to the Sprint store and they told me that my phone verified and were not hardware problems that may be found. I said at the time on the update of the software of MR5 and was anxious to see how the phone after the update.

  I received the update on Wednesday and the phone worked fine. No appeal of ghost, no network connectivity not problems, only dropped the call.

  Now, Friday morning, I lost network connectivity despite seeing the strength of the signal and had to perform a soft reset to regain connectivity. My wife and I bought this phone at the same time. She had many calls interrupted before the update and we both experienced after that update eventhough signal showing on the phone is at least two if not more bars.

  Is this a known issue? Is it going to be/CAN this be corrected by a software update? Is this phone a lemon and he'll remember?

  I LOVE this phone. I don't want to get rid of it, but...

  Seriously. It's a phone! Making calls should be the FIRST thing that is done right.

  Please, someone, Motorola, reassure me that this isn't a lemon and that network problems are going to be fixed. I CAN wait, but I don't want to get stuck with two phones for $200 that need to be pampered just to be usable.

  Thank you

  TC

  Yes, it turns out that be was a buggy phone. Two stores tested Sprint phone for reception of the signal and they said that it spent; but as said the technician in the second store, the tests they take place the phone in ideal conditions.

  The two stores I've visited, said they were ready to replace the phone, but my first visit came just before the MR5 update software while I was willing to wait to see if the update corrects the problem. It didn't, but the replacement of the second store phone works fine with upgrading to MR5 and really no problem.

  I'll go ahead and mark this question as a response, but if you experience the same problems of chance complete loss of all network connectivity (Sprint or otherwise), I recommend getting the phone replaced. It is a bad camera.

  Oh and the technician at the second store mentioned the network problems. It has been a problem for them, but the most telling proof of the issue of network is random dropped calls. So if from time to time, you lose a call under the conditions of good network signal, it's probably not your phone and Sprint. I have almost that many abandoned calls as of late, so it could have been the wrong phone I had that really amplified the problem... or... Sprint has got some of the bugs in our region.

  Thank you for looking in. I hope that your problems are as easy to solve as mine and I hope that you are still within your 30 days so that you get a new replacement.

  Best wishes

• Windows Server 2008 R2 with various OS Win interrupted network connections

  Not a question, but a finding:

  Shortly after the upgrade to Kaspersky Endpoint Protection 8, I started to have problems with seemingly random work stations in my area, the loss of their connection to one or the other of my boxes of Windows Server 2008 R2.  Some of the workstations XP SP3, some Win 7 - two BONES have been affected.  The breakdown of connectivity went both ways - the server could not see the workstation and vice versa.  Sometimes if I waited about an hour, the workstation could re-establish his connection spontaneously, but usually I have to change the IP address of the workstation.  Doing so systematically restored the connection.  Release and renew for workstations using DHCP didn't work because they always had the same new IP - address should change to restore the connection.  After a process of exhaustive and exhausting trial and error to determine the cause of this problem (I initially make the connection between the upgrade of Endpoint Protection and this question), I finally determined that the network attack blocker component was causing this problem.  I disabled this component during my assignment and did not have connectivity losses in the three months that I got that off item.  I also had a case when after the reactivation of network attack blocker, I got a workstation loses its connection to one of the servers, and after disabling the network trainer attack once again, work stations that had lost its connection almost immediately restored the connection itself.  So, if you are having this problem and use Kaspersky Endpoint Protection 8, disable the network attack blocker component.

  Hello

  Glad to know that you were able to solve the problem. Your efforts to solve this problem is appreciated.

  You can also publish your solution or results in Windows Server 2008 R2 TechNet forums: http://technet.microsoft.com/en-us/windowsserver/bb310558

  Thank you.
