• ESXi 4.1.0 lost network connectivity?

  For the last 5 days 3 out of 4 of our server show an alarm of "lost network connectivity.  The weird thing is that we have a connectivity total all servers and all virtual servers.  All the lights flash on each swith, port, nic, and everything you can think of.   All the settings on vSwithes are the same with no red x I ran the command esxcfg-NICS-1 and # ethtool - s vmnicX without any problem.  Any ideas?

• New MacBook Pro lost internet connection

  Fortunately brought my MacBook Pro retina display 15 "and connected to a Dell monitor. (Hours of hassle, but I have another question/problem).

  After using it for a while, I lost my connection to my home network. But my older MacBook Pro 13 and my iMac 27 were still connected.

  I took the new MacBook Pro 15 "at the kitchen. And here, I got my connection again.

  So... WHY

  And... WHAT can I do to keep my internet/network connection when my new MacBook Pro 15 alongside other computers?

  AND... Is there a use for my Airport Extreme, when my DSL provides internet and network?

  No use of Airport Extreme is not mandatory

  I use Dlink router and modem and all the Apple stuff in our home works very well

  That said-

  Press Option - then click the WiFi icon and click the wireless diagnostic tests - the process of

  If nothing remarkable is found - let it run in the background as you go about your work

  Also, when you do this - take a screenshot of the gray information and post a photo

  Finally two points-

  1. you have indicated this is a new device - is there sufficient numbers DNS for the tour of your router?

  2. do you know if your router provides 2.4 GHz or 5 GHz of bandwidth?

• I lost my connection Wireless at home.

  I have a time capsule/router.  I lost my connection Wireless at home.  Cannot get internet connection to one of my computers/devices in the home.  Help!

  Need to load more information.

  Feeding cycle you the entire network... Start up in the correct sequence?

  Modem... Wait 2 min

  TC... Wait 2 min

  Client devices.

  If this does not work...

  Tell us everything... what model is the modem? Is this also a router?

  What model is the TC... The base A1xxx please?

  The fact the main TC on... amber green or flashing led?

  Taken in a computer by ethernet that get you internet with wired connection, just all the wireless clients are turned off?

  Tell us about such things and we can work from there.

  But I suggest you a factory reset as well... Here are the basics.

  Start from a factory reset. No files are lost on the drive hard in doing so.

  Universal factory reset

  Turning off the TC... That is, remove the power supply cord or the power at the wall outlet, wait 10 seconds... Hold the reset button... be nice... Turn on always even now in reset... and keep holding in for another 10 seconds. You may need assistance because it is difficult to hold in reset and power on. It will show the success quickly flashing led front. Release reset... and wait a few minutes for the TC to reset and return with the factory settings. If the front LED flashes quickly you missed and simply try again. The reset is quite fragile in these... Press the key while it is just click away and not more... I've seen people bend lever or even break. I use a toothpick as a tool.

  NB. None of your files on the hard drive of the TC are removed... This simply clears the settings of the router of the TC.

  The installer the TC.

  And then redo the configuration of the computer with the Mavericks - Yosemite - ElCapo. (MYELCAP)

  1. the use of very short names... NO APPLE RECOMMENDED names. Without the space and pure alphanumeric characters.

  for example TCgen5 for the base station and the name of the TCwifi wireless.

  If the problem is using wireless TC24ghz and TC5ghz with fixed channels as it also seems to help stop the nonsense. But it can be tried in the second round. IE, plan on a first and second series of changes to fix this... If all goes well... I note other steps can you tour2.

  2. use all passwords also consistent with 1. but maybe a little longer. IE 8 and 20 characters of mixed cases and numbers... no alphanumeric non-caracteres.

  3. If the TC is router, you can ignore this point. It is only a problem when the TC is bridged.

  If ensure that the TC is always the same IP address... you will need to do this on the main router using a dhcp reservation... or a bit more complex setup by using the static IP address in the TC. But it's important for deriving from intellectual property in all directions when MYELCAP do not remember his name for 5 min after a reboot done for poor network management.

  4. check that your share on the computer name does not change... Make sure that it is also in line with the above... short without space and pure alphanumeric... but this change will mess up your TM backup... so be prepared to make a new, full backup. Sorry... keep this one for the second round, if you want to avoid a new backup.

  5 attach the TC disc into the computer manually.

  In Finder, go, connect to the server in the main menu,

  Type in SMB://192.168.0.254 (or whatever ip of TC is that you made static. It's a default router 10.0.1.1 and I encourage people to stick with it unless you know what you're doing).

  You can use the name... SMB://TCgen5.local where you replace TCgen5 with your name of TC... local is the default domain of the TC and does not change.

  However the names are not so easy as... the IP address nor reliable. They are not at least not in Yosemite. The field can also be a problem if you are not clogged or wireless directly to the Treasury Board.

  6. ensure that IPv6 is set to link-local only in the computer. For example wireless open network, wireless and Advanced preferences / TCP/IP... and the difficulty of IPv6. link-local only. Do the same for the ethernet if you use it.

  It is a lot more jiggery pokery, you can try, but the above is a good start... If you still find not reliable... don't be surprised.

  You may need to do more work on the computer itself. for example, to reset the NVRAM/PRAM/SMC... helped some people. A clean installation of the operating system is also useful if you update installed.

• Windows cannot connect to the printer. The name of the printer has been correctly entered, or the specified printer has lost its connection to the server.

  A Windows Server 2003 Standard Edition SP2 32-bit computer is a field, the file and print server.

  A computer on the domain is a machine of Windows 7 Ultimate 64 - bit with HP DesignJet 500 24 printer connected via USB.  The printer is running the latest firmware.  The PC is running the latest 64-bit drivers with no problems to the host machine printing.  The host also has the latest drivers 32-bit (x 86) installed by downloading by other computers on the network.  The printer is configured to share with the share name of HPDJ500.

  Now, on a machine Windows XP Pro SP3 32 bit on the field, I'm trying to connect to the shared printer.  Add a printer > click Next in the wizard of > check "a network printer or a printer attached to another computer" and then click Next > click on "Find a printer in the directory", then click Next > click Find now > HPDJ500 in the list below (the XP machine can see the shared printer on the Windows 7 computer!) and click OK.  At this point, I get an error that says: "Windows cannot connect to the printer.  The name of the printer has been correctly entered, or the specified printer has lost its connection to the server.  For more information, click Help. »

  Alternatively, if I right-click on the HPDJ500 printer listed, then click on connect, I get the same error message but I also see a separate window that says "Connecting to HPDJ500 on H2.ws.net" with the lively projector.  This window also disappears as soon as I clear the error message.

  Please note that this printer worked perfectly as a printer shared, hosted on a machine XP 32 bit on the field.  It works perfectly for the new Windows 7 64-bit machine, but we cannot connect from anywhere else on the network (including the server which translates the same exact error message).  On the server, I also preinstalled drivers thinking there was a problem with a 32-bit computer, trying to grasp the correct drivers from the host 64-bit Windows 7, but that doesn't change anything.

  How connect to this printer?

  Try using the path UNC path of the printer in the Add Printer Wizard.

  Add a printer > network printer > connection to this printer ((deuxieme point)

  Click next to browse (leave blank, the name field) or type the UNC path of the printer (i.e. \\Computername\Printername) path

• OfficeJet Pro L7780: Printer lost wireless connectivity

  The printer (which worked before wireless) has lost the connection to the router (wi - fi) for wireless printing and can not find the router when you run "Wireless Wizard". Have restarted the printer several times, but no chance connection. Summary diagnosis said the network name 'failed '. (I have with other devices wireless connectivity). The Configuration Page shows wireless status is disconnected and shows all zeros for the IP address and the subnet mask.

  Need suggestions on what to try next. Thank you.

• Unable to connect to esxi using the vsphere client

  Hello friends,

  I need a little help.

  a 2 5.0 esxi host and a vcenter than VM.

  My laboratory worked well for days, but all of a sudden do not know why I am not able to connect to ESXi hosts with vSphere Client.

  Error: The request failed because the remote server has taken too long to respond.

  Call "ServiceInstance.RetrieveContent" to "ServiceInstance' server '192.168.1.101' object failed.

  Yes, I am able to connect to vCenter server, when it is connected to vCenter and open the console of the virtual computer, nothing shows up, it's a black screen, as if the virtual machine is turned off. It is with all the virtual machines on both hosts.

  1. I thought that it might have to do something with vCenter and I tried connecting to Host individually which I wasn't able to.

  After completing a few KBs on vmware and some articles, I checked the status of the firewall on both hosts. (attached screenshot)

  

  Checked if my computer can talk to esxi host on port 80, 443, 902. all ports are accessible.

  Disabled the Symantec endpoint protection and checked. no positive results.

  Finally, I tried the ESXi web navigation browser host http://ESXi-IP-address which redirects me to HTTPS connection with Certificate error, when I continue with the cert error, loading of the URL guard and the host page doesn't appear as it should.

  This questions are on both hosts. :-(

  You guys can point me in the right direction to solve this problem.

  Thank you.

  Finally things started working now.

  The problem was with the configuration of the workstation's NETWORK adapter.

  The link on the NETWORK adapter speed was set to Auto negotiate (default), but the speed was detected as 100 Mbps instead of 1 Gbps and MTU has been set at 9014 which I defined manually long back.

  Things use to operate in this configuration that I have configured hosts with MTU 9000 and cisco SMB switch default Jumbo.

  the LinkSpeed of 100 Mbps is bugging me, after changing to 1 Gbps (manual setting) the card NETWORK has deactivated, and it reminded me to switch!

  So I put the LinkSpeed Auto negotiation, MTU 9014, stop the two hosts, restart the switch. restarted my computer.

  Since it uses for things were in a normal state.

  Even the question of the console (black screen) disappeared. :-)

• Troubleshooting ESX 4.1 "lost network connectivity.

  Hi people,

  I made a change in a vSS in the detection of failover network status 'link' to 'Beacon probing.

  Now a have an active alarm with Red State: "Lost network connectivity", but the message in the events of the host does not show that active vmnic of my rising has the problem.

  Sound it no way of knowing which physical interface have this configuration problem?

  Thank you

  In addition, if you wish to arrive linkstate changes in your host you can ssh to the desired host (or via the console of the ILO, etc.) and simply grep for 'link' (provides most of output) or "linkstate" (provides a minimal output, only showing the ascent/descent of the events).

  Syntax of the command (depending on the version of ESXi host that you may need to tweak it a bit)

  ESXi 4.x

  cat /var/log/messages | grep -i link
  

  -or-

  ESXi 5.x

  cat /var/log/vmkernel.log | grep -i link
  

  Here are some example output captured everything by making the maintenance of networks:

• 1. can't connect to VMWare Server when no network 2. Comments or lost when lost network connections

  Hello

  I have two guests of computer virtual on my laptop.

  1. I can't connect to VMWare Server when there is no network.

  This means that I can not launch the guests when I'm at home (with no network) or on the road.

  2. the connections are lost when lost network.

  As a corollary to article 1 above, if I am connected to the work, and that the network is lost, my connections are lost for the guests.

• Maintenance of form session menu tree connected to DB, while other forms are open

  When our application starts, a menu tree module is opened, which contains a list of modules that users can open. When a user clicks on a module to open, the code issues the command open_form (...,..., session). Thus, each form is open in its own session. Maximum idle time allowed during a session is 45 minutes. So after slowing for more than 45 minutes, any module including module menu tree will lose the connection to the database. So if a user, open a module in the module menu tree and past more than 45 minutes of work on this module, when the user returns to the module menu tree, they get an error this menu tree module lost the connection to the database. So the question is, how to keep the module session menu tree connected to the database, even if it exceeds maximum idle time as long as other sessions of modules are always connected to the database.
  
  1. set the maximum idle time allowed in the database for 5 minutes
  2. open the form A
  3. open the form B form it of own session (OPEN_FORM (...,..., SESSION))
  4. work on form B for more than 5 minutes
  5. return to form A,.
  6 fom A has been disconnected from the database
  
  I tried to use the timer, but the problem with timer is when a fire of timers in shape which
  do not currently have focus, and a context switch is performed. The form flickers when the context switch is made and that the current text of the element is selected when the focus returns to the
  current form, that will be a problem for users.
  
  The installation of our client time-out of database for reasons of security and therefore, it cannot be replaced by TIMEOUT CJP.
  
  Keep in mind that we have 600 forms and the application is already in production.
  
  Thank you

  Hai,

  Try connection to the database to WHEN-WINDOW-ACTIVATED the trigger of the form.

  Kind regards

  Manu.

• Lost internet connection - rogue app?

  Hi, I have downloaded a widget to toggle 3G last night and tried it out. It did not work so I uninstalled, but now I find that my phone is now more able to get an internet connection - it seemed have lost internet connection as soon as I typed on the widget.

  Is it possible that the app screwed up my phone this way, or is there another explanation (I'm trying to discover my carrier right now if the network declined - I can still send and receive text messages)?

  I have to reset my phone?

  Too bad. My career has simply returned internet settings on my phone and now it works again.

• Satellite L500 - lost wireless connection

  My Satellite L500 recently lost the wireless connection. I looked towards the top of the Realtek wireless device in Device Manager and it says that the device is functioning properly. I tried to use "ping 192.168.1.1" join the router, and I get "error Transmit - general failure."

  Any ideas?

  Hey Buddy,

  And now Windows recognize some WIFI networks at your fingertips? Your validation lost wireless connection isn't very useful

  You should try a WLAN driver update that you can download from the official page of Toshiba:

  If you can't find or connect to WLAN networks deactivate in the Windows of the WLAN power save mode power profiles. You will need to set for maximum performance.

  Hi Ron,

  1 Windows operating system you are using?

  2. you receive messages or error codes?

  You can read the following article and check.

  Windows wireless and wired network connection problems

  If you use Windows XP, then read the following article:

  How to troubleshoot wireless network connections in Windows XP Service Pack 2

  This problem can also occur when the power management profile turns off your network card.

  You can try the following steps and check if it helps.

  a. click Start, type device manager in start search and press ENTER.

  (b) in Device Manager, expand network adapter.

  c. now you will see your network adapter or adapters if you have more than one. Right-click on the network component, and then click Properties.

  d. go to the power management tab.

  e. ensure that all check boxes are unchecked (check boxallow the computer to turn off this device to save power is off).

  f. If you have disabled the boxes, click ok and restart your system. Put the computer in Hibernate mode and check if you still have any questions.
