W510: Initialization of the slow network

• Hyper-V slow network

  Dell PowerEdge T420, Windows Server 2008 R2 with Hyper-V installed and one configuration of virtual machine 2008 R2 in the Hyper-V environment. Two network cards on the T420 are connected to the same Gigabit switch, one for the use of the physical machine and the other for the virtual network.

  The only thing that is made in the virtual machine of desktop Services remotely, then end users into running a program of medical records that accesses a database on completely separate server. The physical server just Hyper-V, a domain controller and DNS.

  With no activity, ping'ing the prompt of the physical machine or vice versa or a separate database of the guest PC server, we have less than 1 ms response time. However, if there is no activity in the guest OS, ping times vary drastically - between 1 and ms 200 ms.

  I have different power cuts disabled virtual network adapters properties, but this does not seem to make a difference. Looking at the monitor of resources on the VMS, there is generally less than 5% of the CPU and 10 percent of the memory used, and the network traffic when the application is running is less than 100 Kbps (usually less than 50 Kbps).

  On the physical server, the CPU traffic & network are basically the same as the virtual machine, with 80 percent of the memory used (since it is all attributed to Hyper-V).

  Any thoughts on how to solve the slow networking?

  Thanks in advance!

  The solution to the problem is revealed to be...

  Broadcom NICs in Dell servers have a "Tails of Virtual Machine" which is by default enabled setting. Once disabled, the guest operating system has the same network as the physical machine speed.

• Cannot migrate through the required network. Someone please...?

  I've set up 3 ESXi hosts connected via 2 parallel networks. One is a slower network (base 100) on 192.168.12.0/24, and the other is a speed gigabit on 10.1.1.0/24 network. Each host is to have two physical network adapters for each network.

  Home #1 Config is as follows: (also see attached photo)

  vSwitch0 (connected to vmNic0 )-> a

  -Network VM (Machine Virtual Port group)

  -Management network (VMKernel Port) vmk0: 192.168.12.30

  vSwitch1 (connected to vmNic1 )-> a

  -Network SAN (Virtual Machine port group)

  -VMKernel-Special (VMKernel Port) vmk1: 10.1.1.30

  NOTE: Host 2 also has a similar setup with a different set of IP addresses.

  My problem is that when I try to cold migrate a virtual machine from one host to another (in the left pane you see, sound of 192.168.12.30 to 192.168.12.32), he's still doing the migration through the slower network (vSwitch 0). I want to be cold migration through the fastest gigabit set to vSwitch network 1.

  I have not yet tried make clusters or vmotion, because I can't seem to properly configure the network I want to serve. so can you please help me with this? I want to make sure when I do the migration (migration to cold to start), happens through the network of my choice, which in this case is the gigabit network. Thank you very much.

  Hello

  The stream migration cold traffic over the first Appliance for management of the system detects. In your case, there are two, with the slower network, being the first one it finds. There is no way to route based on activity, so that you either the entire network managemernt vSwitch1 or you live with slower speeds. Personally, I'm not sure that I would never have my network of virtual computer on the same link as my device/network management since they are generally two areas of different trust, etc..

• Flex 2 network slows down the entire network

  I bought a Flex 2 a few weeks ago. Installed the software Office 365 and creative cloud by Adobe. Everything worked well on both networks, I connect to.

  Today, performance on the entire network is now gone to the dogs. At first, I suspected the provider or router so crossed all the routines of standard service (this disconnect, which reboot) again and again. Same face, deadly slow performance of several PC and Mac on the network.

  Then, I hit on the idea to close my Lenovo. Suddenly, network download speed of 2 MB/s and the ping from 2000 MS to more normal speeds returned.

  I restarted the Lenovo a couple of times, from 2, 4 GHz to 5 with the same result.

  At some point when I plugged the Lenovo directly into the modem (part of the diagnosis) direct speed seemed faster.

  Because the router works perfectly with all the other machines and I haven't changed a thing on it, and because the symptoms get carried away on the network when the Lenovo is cut, I can only assume that there is something to do with the Lenovo Flex 2 and how it communicates with the rest of the network.

  I should also add that I tried to plug an ethernet cable to make sure that it wasn't just a wireless thing. Still had the slow performance.

  I'm pulling my hair out over this, if I can't fix it, I can't work (no one in my office will be able to work) and will have to return the machine...

  Any ideas?

  Thank you...

  Thanks for the reply.

  After much pulling hair and analysis where the traffic was, it turns out it was a Microsoft cloud service a too aggressive drive that decided to download dozens of large files at the same time instead of in series. This excessive series of connections slowed down the rate of time and transfer of ping everything on the network. Disable updates for OneDrive during periods of work seems to have solved the problem.

  That said, working on this, I see that updates from Lenovo is continually a significant overhead. Do not understand why it takes so resources...

  Thanks again for the response...

• Transfers of extremely slow files on the home network 802.11 g

  Hello

  I have a home network with only two devices (more the router) on this subject.  The first is a portable computer, the second is a desktop PC / multimedia.

  My problem is that when I try to transfer a file from one computer to another, the transfer is terribly slow (for example, a 200 MB file will take 30 minutes).  I know that we cannot wait to be as fast as advertised wireless transfer rates by the manufacturer, but 100 kb/s is just too slow - especially when you consider that I can download files from the internet (on the home network, through the same router) to > 600 kb / s.  So, while I am very confused of what could be the problem, I'm pretty of course it is not a question of signal strength (and leaning me more towards a PC issue rather than a router problem).
  I looked online and saw people suggests to disable remote differential Compression and WIndows meeting space (which I did on both computers) - but my problem persists.

  Someone at - it any other suggestions?

  Thank you!

• Workstation 9 - slow network performance between the host and guest

  I am running windows 8 on the host and installed by 9 trial. Then installed windows 8.1 as a comment system.

  I'm a slow, very slow network between the two.

  If I send files to and from the computer with another guest, transfers are normal, but if I try the same files between the host and the guest, they are really slow.

  I use a bridge connection.

  I read elseware to disable the following on the guest card:

  Large Send Offload v2 (IPv4)

  Large Send Offload v2 (IPv6)

  But that did not help.

  Thoughts?

  Maybe then try Hyper-v, it help you better.

• Slow down the connection to the local network

  I have ESXI 4.1 (free version) installed on a dell poweredge 2900.  I experience very slow network transfer speeds.  For example, if I transfer a 700 MB ISO to a data store using the vsphere client, it takes about 10 minutes to copy, while if I try to copy the same file from one computer to another on the same local network, it takes about 20 seconds.

  Same sort of thing happens during the transfer of a file from one physical machine to one of the virtual machines on the server esxi (vmwaretools installed).

  Is someone can confirm if this is a typical behavior and if not what to watch (other than checking the physical sons).

  Even if you 'other than to check the physical cables' mentioned in your first post, have you tried another cable? Or have you tried to connect another (capable of 1 Gbit/s) system at the end of the cable that is currently connected to ESXi host?

  Please make sure that the vSwitch configuration is set to Auto for speed and duplex on the ESXi host.

• Slow connection to the mapped network drive

  Here's my situation.

  We have 10 workstations, all on the same, all computers running windows 8.

  We have 1 router, 1 switch and a SIN.

  9 computers can access our NAS with ease via the network of navigation or the mapped network drives.  The 10th computer cannot even open the network folder, or the network mapped drives when they appear she clicks 'This PC' falling down.  In fact, the PC 'that' fall down, never actually opens.  The green bar loads the top of the page, but never actually opens.  The network folder, does not yet appear.

  She is able to ping the NAS very well (as well as other machines) and that it can access the NAS by opening a program (word or excel for example) and then opening a folder and navigation, but it is obviously very embarrassing.

  What gives?

  Why can she access the NAS in a program like Word or Excel, but not of navigation?

• I need a few files to restore from a time machine backup to a different MacBook Pro that is connected to the same network

• The bridge network to the ethernet ports

  I have an Airport Extreme base station for my wireless at home. The problem I have is that the base station is not near a few features, that I need to hard wire. I read that you can set up a network bridge and if I understand correctly, this concept, it's like setting up of another wireless device, but this second device provides you with the required Ethernet ports for connectivity. Is it possible to do with the Airport Express secondary device?

  Most of the other posts that I read said to extend the wireless range, but the range of my base station is not the issue. I just need a couple on the way ports. I've heard this can slow down the entire network however. Is this feasible? All known reserves? Advice is appreciated.

  Is it possible to do with the Airport Express secondary device?

  Yes

  Most of the other posts that I read said to extend the wireless range, but the range of my base station is not the issue. I just need a couple on the way ports. I've heard this can slow down the entire network but

  It all depends on if you configure the AirPort Express to "extend" the network... which will lower the maximum speed potential of the network by all 40-50%...or...whether that you set up the base AirPort Express for simply to 'join' the network... which causes a decrease in the speed of the network... but it will provide 2-port Ethernet for wired devices.

  If you need more than 2 ports Ethernet on the Express, you can add an Ethernet 5 port, 8-port switch, etc., to create as many ports as you need.

  Don't know what kind of speed you need for the Ethernet ports, but they are limited to 100 Mbps, then that would be the maximum speed available ports Ethernet on the Express.

• HP 7520: HP 7520 will not connect to the wireless network

  There is some additional information to

  http://forums.Xfinity.com/T5/home-networking-router-WiFi/HP-7520-will-not-connect-to-wireless-networ...

  on this issue.

  Have several APs for a single wireless network allows the printer foolish law.  (Not a Repeater, a second AP connected to the local network with the same configuration of network for security, etc.).

  I solved this problem.  In accordance with the discussion on the link, the problem is that the printer cannot connect to a wireless network if there is greater than 1 for a wireless network (SSID) name wireless access point.

  This thread has had several useful suggestions, but what finally solved the problem, it's the second point has access to a mode where I can create a 'virtual' access point and, above all, a SSID associated.

  Note that not all access points or routers support virtual APs, but this function seems to be more common over time.  Older models is not able to do that.  However, a new access point is sometimes cheaper than a new printer.

  If you do not understand the jargon in the procedure below, I recommend that you find someone who does, then they can do it for you.

  Solution:

  1. On one of the wireless access on the network, create an a new virtual AP with a slightly different name SSID (for example < name of the network - > _1), on the same VLAN (usually VLAN 1).  You may need to put the AP in "multiple AP mode" or something similar, and then restart the AP.  All other settings (DHCP, security, mixed mode b/g/n, etc.) must be the same for the new SSID.
  2. Run the printer Wireless Setup and connect it to this new SSID
  3. Confirm that the printer can be seen by other devices on the network

  Tips:

  • Check the security is the same as the original SSID, Alternatively you can create a vector of insecurity in your network.  Do not WEP-128 when the other SSID uses WPA2 AES, for example.
  • The AP I had had several resets to make it work because of the mode and parameter changes.
  • If you connect the SSID but cannot connect to or be seen by anything on your network, check the new SSID/AP is in the same VLAN as the original.
  • Because the printer is not roaming, and the speed is not a problem for me, I used the access point that could support this solution, which is deeper and slower than my primary AP.  I have not noticed any problems.

  The printer has been reliable on the wireless now on the new SSID, 48 hours.

  I have not upgraded any software on a client of the printer (PC, Mac, phones).

  I think that it is a positive confirmation that the problem is with the implementation of the printer of the stack of network and not with the driver or client software on remote devices.  The 802.11 protocols provide for a network name (SSID) wireless with several access points using different MAC addresses.  I suggest this HP look into this as a potential bug with their network printer for the 7520 protocols stack.

• The Switch configuration and Wi - fi router in the same network

  Hi team,

  I have here is the configuration currently as below in the image. To describe the same internet cable is connected to a Cisco switch, which is connected to the PC in LAN (wired). A switch output is connected to the entrance of the wireless router Netgear Nighthawk AC 1900 Smart model of WiFi router # R6900. Wireless devices (laptop) are connected by the router.

  Each device has internet access. However, I am unable to run software LAN or unable to share any file of devices connected to the switch to the connected wireless devices. I can't ping any device the device wireless wired.

  Can anyone suggest what are the settings that I should do or what are the steps I should follow that will make wireless and wired devices in the same network.

  PS Plus early I tried the internet connection to the wireless router and then out of the router to pass, which has solved this problem. But slowing down my internet speed in wired devices. So, is it possible to have all devices in the network even with the current configuration?

  

  Thanks in advance.

  Best,

  Hardik

  I made wi - fi router reset hardware and configured in Access Point mode, that solved my problem.

• Optimal, set up for the airport and the power network line?

  Hoping to any network gurus can advise on the optimal configuration for my network.  Current configuration is as follows.  1 Zyxel DSL modem configured to act as the router, PPPoE (not the bridge mode) mode, which is the default value.  2. Airport Time Capsule (ATC) connected to the modem via an ethernet cable plugged into the WAN ATC port.  ATC configured in Bridge mode.  Adapter network line connected to the LAN of the ATC port.  2nd line network adapter is connected to the opposite end of the House where the Time Capsule wireless signal is weak to non-existent.  Airport Express (AE) plugged into 2nd network adapter line.  I have a lot of devices (computers, printers, cell phones, DVR, etc.) which must connect wirelessly to the network.  Here are my questions:

  1. is it better to act as the router, rather than on the bridge, as I have to reconfigure the modem in Bridge mode and the most convenient way to connect using PPPoE Airport Airport?  Or is it not important?

  2. my hope is that by using the network adapters and the AE in the part of my house with the worst WiFi signal, I can push the range of my network and all devices to give a good signal.  My hope is that the devices will be connected to any signal is stronger.  At present, ATC and EI do not have the same network name (or password).  It is better for them to broadcast 2 differently named networks, or both would be they networks of broadcast with the same name and password.  Or is it not important?  Is how important it that the ATC is able 802.11ac, EI is just 802.11n?  For reasons not clear to me, even though I have several 802.11ac devices (MacBook Pro and Nexus5x), they are on the 2.4 ghz band (I even if ca is the 5 ghz).  Don't know if something is set up wrong on my ATC.

  All the equipment is running the latest version of the software (OS X, iOS, Android, etc.).

  Thanks for any advice.

  1. is it better to act as the router, rather than on the bridge, as I have to reconfigure the modem in Bridge mode and the most convenient way to connect using PPPoE Airport Airport?  Or is it not important?

  Doesn't matter, unless there is a special feature like the network option of comments on the airport... that would require that the airport be configured as router.  Airports are not known for their reliability, PPPoE, so it is best to have the modem or modem/router to provide the credentials of the PPPoE connection.

  2. my hope is that by using the network adapters and the AE in the part of my house with the worst WiFi signal, I can push the range of my network and all devices to give a good signal.  My hope is that the devices will be connected to any signal is stronger.

  If the two access points use the same wireless network name and password, Mac will do a nice job of automatically move from one access point to another to pick up the best quality signal as they move home... but iPhones, iPads, and most of the PC will not.  If you name the two networks as well, so you will need to get used to temporarily disable WiFi on iPhone, iPad, etc. When you move from one region to the other. Then, when the device is in the new location, turn on the WiFi and the device usually pick the strongest signal from the nearest access point.

  If you use names of separate network for access points, you need to manually switch networks on each device whenever the camera moves from one region to the other.

  Is how important it that the ATC is able 802.11ac, EI is just 802.11n?

  Well, you know that the Express is not "ac" capable, so any device "ac" close the Express will connect at low speed "n".  You will probably not notice a difference in respect if your Internet speed is less the Express features.  If you copy large files from one computer to another or backup on the network, then a device that connects to the Express is going to be slower than a device capable of "ac" that connects to the ATC.

  For reasons not clear to me, even though I have several 802.11ac devices (MacBook Pro and Nexus5x), they are on the 2.4 ghz band (I even if ca is the 5 ghz)

  Everything in the wireless is a compromise. In other words, to get something, you must give up another.  "ca" is used to that in the band 5 GHz, so if your devices are connect 2.4 GHz, they connect to a slower 2.4 GHz signal.

  Here is the compromise...

  5 GHz signals have capacities of speed much higher than the 2.4 GHz signals... BUT... 5 GHz signals are significantly weaker than the 2.4 GHz signals. So you're really not going to get the benefit of 5 GHz, if your device "ac" is in the same room or it has line-of-sight with the router "ac".

  If a device of "ac" is a room or two away from the router "ac"... the device will probably connect 2.4 GHz... because these signals are more powerful penetration of walls and other obstacles a lot better than 5 GHz can never hope.  It is also possible that the 2.4 GHz signal several rooms away the router will also be the fastest signal at this location, because the signal slows down more it moves the router.  5 GHz quickly signals really slow down.

• Slow network

  Just a general question...

  Sometimes, I noticed that our server files on the network of our company is extremely slow sometimes. How do you guys go about programming for speeds of slow network on your internal network and the occasional usage over the WAN?

  First, the express screws are usually very inefficient. I would use the ex file directly. Secondly, it seems that you write to the file in the same spot (part of your code) you do your job. As I mentioned above, you need to separate the file of transformation in its own task. In LabVIEW, this will be a parallel to the main loop loop. Transmit the data to be logged on to the task of logging via a queue. You can find examples for the use of the files and the use of queues in the examples of the expedition. You can also look at the examples of the architecture of producer/consumer. What I am proposing is essentially a producer/consumer build. It would also be useful in the future if you include the code you are having trouble with. It is easier to give advice when we can comment directly on your code, rather than just giving generic answers.
