ESXi network model problem

• Networking question in VMware Workstation / nested ESXi network configuration problem

  Hi guys,.

  I am trying to set up a virtual lab, I setup a domain, a vcenter server and up to 1 ESXi host controller.

  I am really struggling with the network aspect in establishing a vmnic for storing shared, please see the attached screenshots and a few questions:

  1. Is a vmnic a real network map? or vmnic correspond to "network adapters" that you put in place since the setting of your virtual machine?

  I followed a tutorial and implement 3 NICs on the ESXi host, in Bridge mode, I tried this in my configuration of vmworkstation and I lose the connection to my server vcenter to the ESXi host.

  See screenshot attached to how I configured my ESXi host, screenshot is called 'screenshot2esxihost network', I run got each of the maps defined on NAT network.

  

  See also the screenshot of how I have my configuration of network settings in my VMWare Workstation, screenshot is called "screenshot1. the tutorial does not show how it has its editor of the virtual network configuration, but it puts its ESXi host NICs in BRIDGED mode, and I'm guessing that you can set this time within the virtual network adapter. If someone could tell me what changes should I make in there and on the network cards in my ESXi host, which would be really useful.

  

  My domain controller, server ESXi hosts and vcenter are currently on the 192.168.86 range, which currently stood at NAT

  See also a screenshot from the vsphere client - I don't see a vmnic "vmnic0", my goal is to be able to add a "vmnic2" for a separate storage network.

  

  any help would be received with gratitude, I VCP510 review at the end of the month and really hope to be able to get my lab setup as soon as possible.

  The vmnic is the rising 'physical' of an ESXi host. So with the 3 network cards that you configured for the host in VMware Workstation you will see under "Network adapters" and you can use them to vSwitches in the section "network".

• HP 750 055xt: clean install / desire / network driver problem

  Want to 750-055xt. Bought as a refurb. SSD is small, so I put more in and did a clean install with Windows 7 Professional.

  Internet - network driver problem does not connect and I see that the drivers are missing. I tried searching the site, but I can't find the driver.

  It's not a hardware issue because I can put the other drive and it works fine.

  I am struck an impasse with the search tool. I need to copy the driver on another computer to move.

  All of the suggestions.

  Thank you.

  Hello:

  Page for your model motherboard plug indicates that there is a CG-RTL8151GH-Realtek gigabit ethernet card.

  See if the W7 directly from Realtek driver works - 3rd driver on the list.

Other computers never have this problem.  My laptop is fairly new, and I'm quite puzzled as to why he's in trouble.

• With device log Insight network connectivity problem

  We manage the virtual appliance 1.0 - beta and I noticed that the virtual appliance will fall the network periodically for a short period. I had constant pings, it will and it will just stop respond for anywhere from a few seconds to several minutes. You can also see in the capture where the data is missing in the user interface of screen attached. I know that we are not the problems with our ESXi hosts or dvSwitch because there are many other virtual machines running on the same host ESXi and same VLAN and they are not network connectivity problems. Does anyone else know this?

  Sounds like a network problem. Perhaps you have a dual IP / MAC address on the network? Do you perhaps have a routing problem on the network log Insight's sitting on that?

  Can you generate a bundle of support and download the instructions here: http://kb.vmware.com/kb/100852 (no need to SR just create a file called mvanbeck)

• Router C4780 wireless network belkin problem

  I have a C4780 which worked well for several years with at least 2 previous routers. I have a Belkin AC1800DB have changed recently and now unable to connect to the router (laptops are connected wirelessly to Belkin WPA2 network without problem).

  When I run a network of C4780 test report it says local networks are detected (including Belkin WPA2) but shoes FAIL against network name SSID found. Similarly the wireless Assistant from the installation disc, the list of available SSIDS for the connection is empty. C4780 both Belkin have WPS, but this does not work in mode button or Pin.

  Because the problem is to find the SSID for all networks I do not think that his associate Belkin (just strange that the problem occurs at the moment I change the router).  But as the C4780 connected perfectly to my previous router, that I do not understand why I now this problem of wireless network connection.

  Any advice much appreciated.

  Try this.   Configure the router to a wireless channel fixed as 1, 6 or 11, never 'auto '.   'Mixed' mode, try now.

• Network Configuration problem

  Hello:

  Since last week, when I click on an icon, for example, the Page Home/Windows 7 does not come on the screen.  Instead, warning to appear at the top of the screen saying... Problem with Internet connection or Network Configuration problem.  After 5 minutes, or later, however, the screen came, but it is very slow to open web pages.

  This problem occurs most often during the night, however for the last two days, sometimes also during the day.

  Until this problem started out of blue, wireless connection with Comcast was very smooth-ride,... instantamously the homepage of popping up.

  Hints on this would be greatly appreciated.

  Thank you

  This sounds like a problem with your Comcast service. In the United Kingdom, I would suggest that you run a speed test on your connection speed. You can get no doubt do the same wherever you are. While it could be the quality of your line, the calendar offers it's the volume of traffic from when children arrive home from school until they go to bed.

  You could compare notes with other Comcast customers.

• Home wireless network connection problems

  What should I do if I normally connect to the wireless network does not appear?  It is not a network card problem, because I can connect to other wireless and school and other places.  I tried to reset the router, ping and by unplugging and seeing what I could understand on the computer at home, but nothing does.  Any ideas or suggestions would be greatly appreciated.

  Thank you.

  Hello

  Have you tried other computers to connect to your router? You use both wire and wireless
  connection?

  Unplug the modem and Router 3 + minutes. And then reconnect the modem - when it is running
  Plug in the router - when it is running - restart the computer. This is known as a hard reset.

  Check with your router manufacturer support.

• Wireless network connection problem

  Nice day

  I have a wireless network connection problem and I ask for help to resolve.
  What surprises me that this problem appeared suddenly, I used to connect to the WIFI correctly but two days ago my laptop could not connect to the WIFI and more.

  Other devices and computers connect with success so I think that the problem in my laptop.
  I don't have any changes on my laptop or windows, antivirus, drivers... updates or installed new software.
  Troubleshooting of Windows detected 'router or access point issues '.
  -Reset the router does not resolve the problem
  -Network adapter is enabled.
  -State of wireless card "working properly" and "update".

  I read a solution on this site, which was to change the properties of the wireless adapter, but the changes mentioned does not appear in the pilot of my laptop...

  * My laptop info. :
  DELL INSPIRON 3521
  Windows 7-64 bit
  Dell WIreless 1703 802.11b/g/n(5.2GHz)

  Sorry for this long to make, I appreciated all the help.
  Thanks in advance.

  Hello

  Have you tried to reset your laptop to a time before this issue started with a Windows 7 Restore Point?  If it is a parameter change or software this restore point can help solve what is at the origin of the problem.

  I'd also, of course, when you are resetting the router, to make sure that you let it sit for at least 30 seconds to a minute before plugging power back in.  You may need to do a few times to clear his memory to be able to connect.

  In addition, have updated the drivers for the wireless card?  What version of driver currently installed in the system?  You can consult our support site, enter your serial number and click on drivers & Downloads to find the driver for your wireless card.

  Finally, have you tried to empty the wireless profiles that are currently stored in your system?   If you delete the profile current wireless (which is to control your connection to the router), reboot your system, and try to reconnect Windows will rebuild the profile and hopefully allow you to log in again.

  I would like to know if any of this helps.  To help resolve this more effectively please click on my user name Dell Todd and send me a private message with the Number of Dell Service from your system.  Please keep all troubleshooting and discussions on this thread open so that others can find the information they need to solve their problems.

• Unit's network communication problems

  I developed a demo using unity's c#. Client to connect to the server and to send information, and I tested it on windows Pc (start two app, one is server, another is client), and it works very well.

  But when I use my z10 to test (app on windows as a client), app on z10 as server, I can connect but I can not send information.

  When I use the z10 as a app on windows as a client server, it cannot connect.

  How can I solve this? What is the problem of my code or the problem of bb10 os.

• Failure of the motorway E - there are network connectivity problems or this peer has different support encryption (AES / non - AES software)

  I do a bunch of highway E and C, but it I show error on cluster of highway E:

  Failure - there are network connectivity problems, or this peer has the support of different encryption (AES / non - AES software)

  This highway is part of a cluster, but is not the master of the configuration. Configuration changes made on this highway may be lost. More information about the Clustering help page.

  !

  What is the solution to fix it?

  Locally add cluster of highway or having to make cluster of 4 motorway between locations?

  How far are the peers of the highway on the other, what is the round trip time?  This should be within 30ms.

  Can you confirm that all highways in the cluster have the same keys option installed on all peers, as it is a requirement, call license quantities can be different, but the features option enable/disable keys must be the same.  Additionally, make sure that the version of the software installed is the same, that you have a version mismatch or could be active where encryption the other not.

  Regarding the "this highway is part of a cluster, but is not the master of the configuration... '. "this message is normal for a node that is not the master, as it is said just only make changes on the master, since all changes on the slave will be replaced by the master.

  Suggest you watch on creation of Cluster Expressway and maintenance Deployment Guide (X8.8) in case you have not yet.
