• 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.

• Tandberg Codian MSE supervisor - continues to lose network response

  Hello

  I have e-mail notifications setup on MSDS to tell me when my MSE loses network response. In this case every hour during the day for about one minute. Where can I start to do troubleshooting to understand why my MSE will lose all chance connection.

  The current software on MSE: 2.3 (1.46)

  Concerning

  What TMS version are you running?

  There is the possibility that the TMS incorrectly reports that the MMS is not there.

  There is a bug with some of the releases of TMS14.x where he seems hurt some devices as offline, or with incorrect credentials.

  I think of my old emails, as the upgrade to TMS15.0 solved the problem.

  We have not seen this kind of problem recently (with TMS15 +) where we used to get quite frequently in the TMS14.

• 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

• Airport Extreme intermittently lose network signal

  For several days, I repeatedly lose my network signal.  I spent an excessive amount of time troubleshooting including going so far as to have a comcast tech come by today, but it's a bit like going to the doctor... When the doctor walks in the room, all of a sudden all the symptoms disappear.  Anyway, has dropped signal, network cannot be found, restart the modem and the router on a regular basis.  some time, restart allows the devices to the network.  Sometimes it doesn't.  And when that happens, it is not compliant and will lower it again anywhere from immediately or several hours later.  Comcast claims signal input in an apartment is good as well as the modem is good.  They think it is my Apple Extreme router.  However, the same missing network behavior occurred even when I bypassed the router and used a direct connection to the modem via ethernet.  For example, if the signal coming from the wall is good and the modem is good but I have the same problems even if without going through the airport, what happens?  Hope that someone out there more knowledgeable and patient I can sort this out.  I am happy to buy new hardware but want to be sure, that I need.  Comcast, recommended, of course, I get a new modem.  Motorola, of course, said that there is nothing wrong with the modem.  So now, I go to the Apple people to evaluate the remaining product that is Apple.  Thank you.

  However, the same missing network behavior occurred even when I bypassed the router and used a direct connection to the modem via ethernet.

  Is your modem or ISP...

  The problem occurs intermittently... the curse of living in any repair technician. If they can see what is happening, then they can work on that.

  You have no choice but to continue to pursue to the ISP.

  For now use mac plugged directly on the modem... and as soon as he left the ring and say that it does not work now.

  This modem do you have?

  Certainly, we have experienced problems with the Modem Motorola... SB6141 is the top of the list.

  The problem with the airport is well known... but I would have thought that the live Mac should be ok...

  In any case a new modem is not expensive and worth it.

  The zoom seems the best solution... check that it is on the list of comcast.

  Zoom modem.

• VM loses network connectivitiy if I'm moving to 2nd network card on the host

  Hello

  I have a server esxi 5.5 2 NIC. If I move my vm network to my 2nd nic (keeping the IP of my vm configuration), they fall outside the network (of yellow exclamation in the internet connection of Windows/loser).

  Is there something in esxi that I failed to do?

  Please notify.

  UM... the problem is maybe on the physical switch, a Cisco called port security feature can turn off a switch port physical if the same MAC address appear on different ports... and given that the virtual machine was working on the 1st vSwitch, the MAC address of the VM has been associated with the switch port physical connected to vmnic used for the 1st vSwitch , but when you change this virtual machine to the 2nd vSwitch the physical switch detects the address MAC tries to associate vmnic used for the 2nd vSwitch so that disable the physical switch port where the vmnic1 is connected.

  The solution is to ask your host if they are really using the port security and disable it.

• ESXi hosts SBS 2011, clients lose network via VPN

  Greetings,

  We have an ESXi Server (in a lab environment) who perform a SBS 2011 and a Windows 2003 (Terminal Server).

  We have two locations, connected via a VPN IPSec (2 boxes of ClearOS).

  The ESXi host is located in building r. customers in the construction of an experience no problem at all.

  Customers in the building B often lose connectivity to network share. We also failed when copying data. Do not forget that the servers are located in the building and issues affecting only users in the B building.

  We noticed the event ID 2012 on the VM SBS 2011 event viewer.

  The two buildings are connected to a cable broadband 10 mb / 1 mb ISP.

  NOD32 Antivirus is installed on the two virtual machines

  Any help would be appreciated!

  Thank you

  Hello

  There are a few things to look out for more such links. The following steps were made on W2K and W2K3, so that they are still applicable for you.

  (1) is the VPN capable to manage the packet being sent by site B MTU size, sometimes the MTU on VPN size must be less than the default value of 1500 set LAN. You can check this scathing your server with a command like

  ping f-l 1500

  If you get a message like "packet needs to be fragmented but DF parameter.

  You will need to reduce the size of the MTU TCP/IP in the client registry. Try to ping the server with a size of 500 bytes and see how it goes.

  (2) setting the server TCP/IP stack

  In the registry HKLM \SYSTEM\CurrentControlSet\Services\Tcpip\Parameters, create or modify value DWORD of TcpMaxDataRetransmissions. By default, it is set to 5, but I recommend double this value to 10. The TcpMaxDataRetransmissions value is the number of retransmissions of TCP of a data segment without acknowledgement of receipt on an existing connection. TCP retransmits data segments until they are acknowledged or until the expiry of this value. Basically, when a client does not meet a package from the server, the server will attempt to retransmit the packet until TcpMaxDataRetransmissions many times. By increasing this value, you give the customer more time to answer on the server, which will help improve the flaky connections or connections with latency or higher than normal packet loss.

  HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\KeepAliveInterval and HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\KeepAliveTime.

  Both entered DWORD.
  KeepAliveInterval determines the interval between retransmissions keep until a response is received. If a response is received, the delay until the next keep alive transmission is again controlled by the value of KeepAliveTime.
  The connection will be broken once the number of retransmissions specified by TcpMaxDataRetransmissions is remained. KeepAliveInterval is set by default at 1000, which is one second.
  KeepAliveTime controls how many times TCP attempts to verify that an idle connection is still intact by sending a living package of the Dungeon. If the remote system is still reachable and running, he will acknowledge receipt of the living transmission to keep. KeepAliveTime is set by default to 7 200 000, or 2 hours.

  I hope this helps.

• WRT120N loses network connection

  Hello

  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 have no problem with my internet connection, computer laptop or PC can access the internet at all times.

  The problem I have is that for some reason, maybe after 5 minutes, my laptop drops its connection with my PC, and vice versa, so I can't access their shared files (be it from my laptop to pc or laptop). I checked between two firewalls, etc. and all the rest. After reading a few posts, I see that others have the same problem.

  Any help would be appreciated. Thank you

  I disabled my firewall on my laptop wireless. But kept the antivirus on yet, and things are working well.

• C4780 loses network connection

  My C4780 has constantly been ignored by my home network. It was a problem early on, but a few months ago, I installed a patch that was supposed to solve this problem. It worked for awhile, but now the problem is back. The guard device manager disable the printer after a day or two and I have to keep reconfiguring. I'm running Win7 Home Premium (x 64) and my router uses WPA - 2 personal security. I tried to uninstall completely and re - install all the drivers which is time consuming and the HP software but the problem persists. It is a very frustrating problem. Y at - it a fix for this or it is time to look for another brand of printer?

  We will set an IP address of the printer:

  -Print a the front of the printer Network Setup Page. Note the IP address of the printer.
  -Enter the IP address in a browser to reveal the internal settings of the printer.
  -Choose the network tab, then wireless along the left side, then on the IPv4 tab.
  -On this screen, you want to set a manual IP address. You must assign an IP address outside the range that the router sets automatically (called the DHCP range). You can find the beach DHCP from the router using its internal settings page or in its manual. Use the CD that came with your router or type the IP address of the router (ends para.1) in a browser.
  -Apply the subnet 255.255.255.0 (unless you know it's different, if so, use it)
  -Enter the IP of your router (on the Page of the Network Config) for the bridge and the first DNS. Let the second white.
  -Click 'apply '.

  Now, stop the router and printer, start the router, wait, and then start printing.

  After that, you will have to redo 'Add printer' using the new IP address.

• RVS4000 lose network access and internet - reboot required

  I have recently bought a RVS4000 router and experience of major service disruptions.

  Almost daily router RVS4000 loss of internet connectivity.

  I noticed that when this happens, I can not connect on my pc which is connected to the network RVS4000 router.

  The only way to restore connectivity is to restart the RVS4000 by of disonnecting power and voltage to the top.

  WAN router is connected to a cable modem.

  The RVS400 has two connected on PC. (port 3 & 4)

  I have a 8-port switch Cisco connect to the RVS4000 with 3 PCs/devices additional to this topic.

  Is it possible to determine what is happening?  Newspapers do not seem to indicate a lot.

  What is the cause?

  Please need help, ideas, suggestions!

  Thank you.

  Tony

  Hi Tony, first thing to do is to make sure the router is running the latest firmware 2.0.3.2

  http://www.Cisco.com/Cisco/software/release.html?mdfid=282414013&CATID=268437899&softwareid=282465789&release=2.0.3.2&relind=available&rellifecycle=&RelType=latest

  For good measure, after the upgrade of the software, reset the device to factory default. Once completed, I would put the minimum requirements just to have internet access and then wait and see if there is a problem.

  If the problem happens again, best thing maybe is set up an external syslog server so it can capture events when the router is not accessible, which can point to a good direction.

• VM guests loses network

  Hello, VMware novice here, I have an ESXi installation recently installed a Dell 1950. I installed CentOS 3 guests and they work very well, however, when they are restarted, they usually do not return to the top with network connections. I noticed that I need to uncheck 'Connected' to their NIC under the options for each guest, record and save, and the network reappears as if by magic.

  Someone at - he seen this behavior and know a cause/solution for this?

  Thank you!

  Install the VMware Tools... I'm running two CentOS 5.x (5,4) VM on my u1 ESXi 4 home with no problems... Also, make sure that the network in the virtual machine configuration is correct. The tools, very probably, will solve the problem although...

  But when I uninstalled Norton, then downloaded and installed Microsoft Essentials, suddenly everyone
  time I put my Windows Vista PC to a low power state I lost my internet connection when I tried

  It's my duty to go through the entire process of starting again.
  "Sleep my mode" doesn't seem to work as he always used to.

• 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.
