• TimeCapsule loses network connection

  I have a TimeCapsule (new version of turn 2014) and I noticed that my backups are not being every hour. Utility app showed 'device not found' on the network.  I restarted the time capsule - it connects to the network successfully for about 3 minutes and then "Device Not Found".  I restarted my TimeWarner cable modem then restarted TC even question.  My wifi router is the TimeWarner modem and I have 60MB of speed that I'm guaranteed up to 50MB, so all right from the internet side.

  I did a soft reset... same question.  I did a hard reset and used the previous settings - same issue (3 minutes network, and then click device not found a few moments later).  I guess I can do a default network but since absolutely no changes to the network settings have work probably months (7 + months) I don't see why this would happen.  I don't want to lose my entire backup (s) risk is... I have no other way to save my December 2015 MBP.  * Funny, it is the TC network shows, if I hit him "save now" finds TC but TC for 3 minutes then turns off network; However, the backup actually occurs successfully. But will not back up again until I restart then the TC on the network these 2-3 minutes before losing the connection.  Help.

  I have a MBP 15 mid-2015 "and capital El v10.11.6.  My TC etc are all up to date on the versions of software too!

  Many users have posted on the forum with the same number of "Device not found" in the last days. Looks like almost every new post is about it. This is one of a few minutes there are, for example:

  TimeCapsule loses network connection

  Rumor has it that the 10.11.6 recent update is part or all of the problem, according to the opinion.

  The "fix" of the day is to disable Back to My Mac in AirPort Utility, that seems to work for users who have helped with my Mac. Of course, you lose functionality when you do this.

  No solution yet for users who do not use Back to My Mac, because they cannot turn off something they did not.

  Apple is silent, not so much we can do until Apple recognizes that there is a problem (which they are not since yesterday when I spoke to them).

  Stay tuned.

• Apple TV loses network connection

  Why my Apple TV loses its network connection? Each article I found said it's your network... It is not my network. I have 4 other Apple TV on my network of 5 ghz and they work great. I've seen articles that say it is the signal of my AirPort Extreme. It is not the case... As I said previously I have 4 other Apple TV scattered throughout the House and Apple TV that has the problem is sitting right next to the AirPort Extreme. All 5 Apple TV are Gen 3 and the updated version. So is there anything else I can try before buying a new Apple TV?

  Other devices work does not have a network problem.

  You can get a report ffrom istumbler, netstumbler or similar to see a current state of the network. This will give you the strength of the precise signal, noise, networks nearby. With the help of Ethernet will also check. You can also test it on another network

  Right after the little help with my home network. I have an ADSL Dynalink RTA 1320 connected to my WRT120N is connected to my PC which is running Vista. I have a new HP laptop running Windows 7 that is connected wireless to my home network.

I checked between two firewalls, etc. and all the rest. After reading a few posts, I see that others have the same problem.

• Lose network connectivity after the change of speed of the NETWORK card of 100 to 1000

  I changed my speed of 100 to 1000 vmnic0, then I lost all connectivity to the server.  I had to switch mode not picked up and back to 100.  Then I thought that maybe it's a requirement that it is plugged into a gigabit switch, so I plugged it in one and I can't connect to it even if the light shows of link on the server and the vSphere client.   Since I have an Intel Pro 1000 card, should not the system automatically see as such and not a 100 card?  Or does not automatically detect the speed of connection and change it accordingly?

  Try replacing the cable. Make sure auto-negotiation is enabled on all connections.

• 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.

• Losing network connectivity in Windows virtual machines

  We have a problem with Windows VM where they lose network connectivity after being inactive for some time.  After you go in vcenter server and log in to the virtual machines, they begin to respond to pings again.  For any reason but after they are inactive for a period of time, they stop responding to pings, which means that you will have to return in vcenter server and log, and then their network connectivity is restored.  I was wondering if anyone has experienced this problem or have any suggestions.

  Looks like the virtual Windows machine has an option like

  "allow the nic to the power power off in case of inactivity"

  permit.

  Check the energy saving options

  Hello @fairgame,

  Thank you for visiting the Forums from the HP Support! The forums are a great place where you can find solutions for your problems, with the help of the community!

  I understand that you have a problem with the WiFi and wanted to help you!

  First of all, try to review the next steps, offered by community member @Great-Christine-Tree:

  First of all, we have a step by step guide to guide you through the process of diagnosis here:

  HP PC - troubleshooting Internet and wireless network

  A second option is to try the following steps:
  Powercycle the network:
  1. turn off your laptop.
  2. unplug the power to your router.
  3. disconnect the power to your modem.
  4. wait at least 45 seconds.
  5 reconnect the modem and wait for it to come back online.
  6 plug in the router and wait for it to come back online.
  7. turn on your laptop and test your connection.

  Turn off the power to the adapter:
  1. open Device Manager. (Win Key + R > type devmgmt.msc > OK)
  2. expand the network adapters.
  3. right click on the Ethernet adapter / wireless, and then click Properties.
  4. click on the power management tab.
  5 remove the check mark next to allow the computer to turn off this device to save power.
  6. click on OK.
  7 test cycle.

  Reset the TCP/IP settings on your PC:
  1. go to your start screen/menu and type CMD.
  2. right-click on the command prompt icon and select run as administrator.
  3. in the window that opens type "netsh int ip reset resetlog.txt" without the quotes and press ENTER.
  4 restart your PC and test.

  It can also help to reset the winsock catalog:
  1. go to your start screen/menu and type CMD.
  2. right-click on the command prompt icon and select run as administrator.
  3. in the window that opens type "netsh winsock reset" without the quotes, and then press ENTER.
  4 restart your PC and test.

  Reinstall the NIC drivers:
  1. download the drivers from here , but do not run them again.
  2. go to your Start menu/screen and type Device Manager.
  3. expand network adapters.
  4. right click on the wireless adapter and choose uninstall.
  5 install the drivers downloaded in step 1.
  6. restart your PC and test.

  Test an ethernet connection:
  Explicit. Test if the problem persists on a wired connection to the adapter hardware troubleshooting wireless can be directed to the appropriate areas.

  Test another connection:
  Many people excluded their home network as a problem if another device working on the same network. Networking is not as simple as that. Each device interacts differently with your router or modem and it is impossible to exclude the settings for this device until the laptop has been tested on another network.

  If these steps do not resolve the problem, try this document published by Microsoft for network management issues: wired and wireless network problems. You can change the operating system with the drop-down list in the upper right of the document.

  Please let me know if this information helps you solve the problem by marking this message as 'accept as Solution', this will help others easily find the information they seek.  In addition, by clicking on the Thumbs up below is a great way to say thank you!

  Have a great day!

• HP LaserJet M1522nf begins to lose the network connection

  Hello! I have HP LaserJet M1522nf and I use it for about 1 year maybe, but since last week, he begins to lose the network connection (ping failed, web interface does not work too). To be correct, the printer is connected directly to the network through an ethernet cable, and the cable is perfectly fine. His work when you turn it on and for the next 5 to 15 minutes, but after that it lost connection (tasks start fails).

  I really like using little aid, some perhaps of advice. Any suggestions?

  Hard reset the router to factory settings and reconfigure your settings.  Pass the cable to a different port on the router.  You said that the cable was good... change anyway.  Try now.

• 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.

  Hi DustinMoor3,

  Follow the troubleshooting steps posted by Shekhar (marked as the answer) in this thread to solve the problem with no connection to the primary DNS server, in particular the method 2 worked for other users.

  * These steps should also work for Vista *.

• SG 300-28: duplication of port: loses the network connectivity of the destination host

  Hello

  We have two SG 300-28. On one of them, I have configured the port mirroring because a host behaves strangely. When I create the mirror, the host connected to the destination port is not available any longer, for example, it does not meet a ping. Port source packages appears on the port of destination, but no package intended to be the host itself. East - this behaviour right? I agreed that the host on the destination port is always accessible, as it would be without the mirror.

  Bernd

  HE Bernd,

  Yes. This behavior is just. That's how Port Mirroring works. The host connected to the Destination port loses its connectivity and it can act as a monitoring device using programs like WireShark (and monitor packages coming to and from the Source port (s)). All configurations on the destination port are substituted.

  Let me know if you need assistance,

  HTH,

  Vijay
