• The evil network speed

  Hi all

  I have two ESX, HOST A - B of the HOST, a gigabit of Pentecost on infrastructure gigabit network card.

  Network cards in both armies are recognized in gigabit, but the speed of data transfer on HOST B is comparable to a 100Mbit. I changed the cables, ports on the brewing and the switch panel: no result. All physical cards should be the same speed (evil), but in the vSphere client are "certified" gigabit.

  The virtual switches are configured exactly like those of the HOST

  Hello

  Maybe you should check the physical switch interfaces connected to host B.

  I would check if any errors and the amount of traffic through this interface.

  Best regards

• Reference Dell MD3200i correct editing with IP system and the NIC for faster network speeds

  Hi all

  I worked on this project for a while now. I did a lot of research and have contacted Dell several times. I need help.

  I have 2 sets of identical to use for Hyper-V clusters servers. We bought a Dell MD3200i in November, we also bought a Dell 5424 switch and a Cisco SLM2048 switch. These servers have Real Tek 2 network cards for iSCSI Jumbo frames is 9 k

  The Dell MD3200i is two SAN controllers. Dell 5424 is the iSCSI optimized switch and Cisco is a 48 switch ports. iSCSI is on its own network that nothing else is connected to it. (There is an Iomega NAS and a promise Vtrak SAN Tech with all current domain of execution with iSCSI controller)

  Reference Dell MD3200i controller 0 Port 0 192.168.130.101 controller 1 Port 0 192.168.131.101

  Controller controller Port 3 0 192.168.130.103 1-3 192.168.131.104

  Cisco switch has 1 VLAN n ° 1 on it and the 130 subnet inside elements. There are 8 connections to the switch. 4 controller 0 and 1 of each of the servers. It has an IP of 192.168.132.4, but that switch IP does not make difference. Lighted Jumbo frames

  Dell switch has 2 of #1 for various things such as the domain controller, Vtrack, and SIN. Subnet 2 is 131 and has a total of 8 connectors inside. 4 in 1 controller and 1 from each of the servers. Lighted Jumbo frames. The switch IP address is 192.168.132.2

  iSCSI tab click on add 8 MPIO sessions at each of the ports on the MD3200i from Dell, target. For example, I added 1 session of 192.168.130.101 using it. Add Session,--> activate--> Advanced Mutlipath--> Local--> IP 192.168.130.110 initiator and target 192.168.131.101 iSCSI adapter. This is repeated on all servers. 4 connections for each NIC.

  The network is very slow. It revolved around 2 to 4 MB/MIN and it should be much faster. Initially, we had only the Cisco switch with only 1 VLAN and everything connected directly to it. I read somewhere that MPIO has been the problem, so I went through the same configuration but does not verify the MPIO checkbox above. Once this has been done, the network speed went up to 1.5 GB/Min but modular storage Dell was not happy, and virtual servers would fail and the connection is not very stable.

  What wrong with my setup? Can I directly home and fix the servers directly to the PowerVault and will make stable and allow for failover and redundancy NIC? I need to get this stable so I can move with something else.

• VM network transfer speeds are two times faster than the speed of the physical network

  My stats from the server:

  1 Gigabit NIC onboard

  1 PCIx dual port Intel Gigabit NIC

  1 1 to Seagate HARD drive (for virtual machines and ISO storage)

  Network:

  Belkin AC1200 F9K1113v4 Gigabit router

  Computer:

  Sony Vaio i5 2440 M, 8 GB, 5400 RPM HDD

  The main objective of the ESXi server should be used as a NAS, but with the additional ability to run Windows or Linux VM casual as a game server.  I currently have Open Media Vault controls 1 to 4 hard drives in a configuration RAID10 of software with a plugin SMB/CIFS to provide access to the shares through the windows.

  Network management is through the card on board.  OMV uses its own port on the Intel network card.

  The problem:

  Transfers of networks (upload) to my Windows 7 PC to NAS OMV are slow (average 40MBps).  Playback speed (downloads) of SIN is about 100 Mbps, which is decent.  I tested the disk write speed using the hdparm since the console command, and they are all on average 110 - 130 Mbps.  Why is my computer so slow transfer speeds?  Is there a setting to ESXi which limits my network connection?

  Some things I noticed:

  If only I start a computer Windows 7 virtual on ESXi VMNetwork, my transfers from the Windows 7 VM to the NAS VM on average 105 MB/s, while the playback speed is around 90MBps.  If I could get my physical network to transfer at these speeds, it would be satisfactory.

  Can someone help me?

  Hello

  I presume that the OMV is the culprit here. See for example this discussion: http://forums.openmediavault.org/index.php/Thread/5507-Extreme-slow-samba-speeds/

• After briefly losing service, iPhone will fail to connect to the cellular network until you restart

  When my iPhone lose service for any period of time, as when he drives through an area that is not covered or go inside a building, unit reverts to the cellular network once he's back in the range. I tried to switch the plane made to make additional research; It does not work. I tried to reset network settings. It doesn't work and now I have to re - enter the password for each network wifi (disappointment).

  The fix, however, if I turn the unit completely off and the power supply back on. Only to reappear again the next time that I lose the service.

  What in the world is the cause and what can do about it?

  Things to note: MRI comes back fine. Issue JUST started this week. Device has been restored there is from a backup about 3 weeks because it is a replacement for one that I destroyed.

  Post edited by: Hydrochlorick

  I can confirm the exact behavior that you are experiencing.

  My iPhone brand new T-Mobile SE (1 week) did not have this problem on iOS 9.3.5. He found his connection to my mobile operator without any problem before the iOS 10 update.

  I also tried all the things (airplane, network reset mode, etc.) that you tried. Will not fix it. The only thing coming back my cellular service is to power cycle the phone.

  It's a real problem for me as I work in a story 72 building (no service in the elevator) and I have unfortunately to enter and leave the building a certain number of times per day.

  You have not specified what iPhone model and what version of the OS. Can you clarify?

• The local network settings for arbitrarily lose connectivity with ADSL modem

  Hi all

  I have a SAGEM 1500WG ADSL modem for internet connection and a laptop Satellite A100 (PSAA9). I noticed that arbitrarily, the ALARM led on the modem of DSL connection worked again (according to the lights on the modem) and the real problem was that I couldn't ping my modem. The problem was inside my local network. I can't be sure that what happened outside my LAN because I could not reach even the modem.

  The only solution is to reset the modem. After 4-5 months of use, I have concluded that, whenever this was happening, I used Azureus to download a movie and this download was pretty slow (for example because my counterpart have fast connection). Also, I was connected with wire and NOT using the modem wireless. This means that: the problem never appeared when the wireless or Azureus works and download a significant amount of data.

  I wonder if the LAN driver has any firewall installed on it. Or if she has any function that transforms the power driver LAN offshore when there are very few or no data go through it for a certain period of time.

  Or East-Azureus has any odd décor that reminds you of something above?
  The combination I think is problematic is "adapter LAN + Azureus work + very little data being downloaded. Maybe I'm a little confused. Anyone who has experienced the same problem or can come up with an idea will be extremely useful.
  Thank you very much.
  Lambros

  Hello

  Don t think that there is a problem with the LAN settings or the LAN driver on the device!
  Your data transmission to low and transfer depends on your service provider Internet (ISP) and the server.
  Your Azureus application does not for me, but in my easy it s a transfer of connection and the data of the software simply PEAR-pear file also depends on the number of users and the connected clients

  Hello

  OS = Windows unilingual 8.1 with Bing [64-bit]

  WiFi adapter = Ralink RT3290 802.11bgn Wi - Fi adapter

  Driver = date 25/11/2013

  Driver = 5.0.37.0

  The situation is like this... I have an ADSL + router to iBall Baton and I had kept initially named as 'Deep' (without the quotes).

  Day 1, I had kept the "SSID Broadcast" to "Hidden" parameters so that no one will be able to connect to my WiFi network automatically. It worked great as I entered manually information WiFi my Samsung Tab 2. Now on the 1st night when I tried to connect my laptop, I found that it showed 'Hidden network', I clicked on it and entered the details and the net connected via WiFi.

  It was really good, I thought.

  Day 2, My Tablet will connect automatically but when I turned on my laptop Wifi it wasn't unable to catch or connect with the hidden network. So, I started displaying the name of the WiFi network. And reconnected both my tablet as my laptop HP 15-r036tu.

  Day 3, I turned on my WiFi... Tablet instantly connected to the WiFi network while the WiFi of my Netbook just couldn't... So I changed the name of the WiFi via the modem settings. Tablet reconnected to the new name of WiFi settings... Done the same with the laptop. Worked great.

  Day 4, today! I don't know everything, just not that hell will not with my laptop, but just, it does not detect my WiFi network. So now that I have to again change the name of my network and then reconfigure all my other gadgets just because my laptop cannot detect the WiFi? Surprisingly, he catches the other WiFi networks around my house except mine!

  Need help! Help, please!

  Hello Swayam_Das,

  Welcome to the HP Forums!

  I understand that you are having connectivity problems with your wireless network. It seems strange that you are able to view other connections network wireless, but not able to see your own. This tells us that there must be some sort of gap between the wireless card and your specific router.

  He also seems to be an update of your wireless network card drivers. You will find them here: MediaTek (Ralink) 802.11 Wireless LAN (WLAN) adapter.

  Let's try to keep things a bit:

  • Is there a firewall enabled in the router?
  • Have you tried running on another channel broadcast rather than hide the name of the network? (See why, here: How to boost your WiFi by choosing speed the way on the right)
  • You check the box connect automatically when you connect to the network? (I know it sounds silly, but never hurts to ask).
  • Your operating system is up-to-date with important updates?
  • Have you tried to reset the TCP/IP stack? (see below)
  • Have you tried to reset the winsock catalog? (see below)

  If you have reset the TCP/IP stack and winsock catalog follow these steps:

  1. Go to your home screen with all the fancy tiles. (Press the Windows key)
  2. Type "cmd" without the quotes.
  3. Right-click on the application from the command prompt and choose Run as administrator.
  4. At the command prompt, type netsh int ip reset resetlog.txt , and then press on enter.
  5. Type netsh winsock reset , and press ENTER.

  After doing this, you must restart your computer.

  Once you have completed all the steps above, it would also help to remove all the networks that your laptop is trying to hold back, to get a fresh start. To do this:

  1. Go to your start screen.
  2. Type 'network settings' without the quotes.
  3. Click network connection settings in the list of results.
  4. On the Connections tab, on the left, choose Manage known networks.
  5. Click on each network listed, and then click Forget.

  Now, log on to your network, reboot and tell me if he reconnects automatically.

• 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.

• Satellite 650 d - WiFi drags on the home network

• Satellite Pro A100 has "limited or no connectivity" & no connection to the local network

  Hello!

  I + really + hope someone might be able to help with this - been going slowly crazy.

  Bought my A100 18 months ago in Australia while I lived there and had no trouble to connect to LANs and others with my wireless. Everything was shipped over to me (here in London) last week and everything seems to have gone pear shaped. The House I live in has Wireless Broadband comes with our Sky Cable subscription, working on (I think - there is no real marking on the device) a router wireless Netgear A/G dual band (108 Mbps 802.11 b/g network). My laptop model is: SatellitePro A100 (part No.: PSAACE-007002EN) and it works on the following network hardware (drivers installed in brackets):

  1394 net adapter (5.1.2535.0)
  Intel(r) PRO/1000 PL Network Connection (9.2.24.0)
  Intel (R) PRO/Wireless 3945ABG Network Connection (10.1.0.13)

  I used the Sky Broadband installation disc to set up the network, but every time I try to connect it tells me that I have "Limited or no connectivity" and will not let me online. I've been on the phone for Technical Support of sky for hours, trying to get this sort, but when I plug in the Ethernet cable to the laptop it will not even get to communicate directly with the router (i.e. put the IP address of the router in explore and view the settings of the router). My 'Connectivity Doctor' shows there is a problem with my wireless connection (which the network has not assigned a network address of the computer), but no problem with my ethernet connection and yet neither will allow me to get online and every time that I try to repair the wireless connection I get an error message saying that Windows could not renew the IP address.

  I have disabled the Bluetooth, reset the router I don't know how many times and made sure that all cards have been activated and crosses without bad red and yellow exclaimation in Device Manager. All network devices seem to be "working properly" (according to the properties of the device).

  After days of weeding through the proverbial haystack of resources online while at work, I think that the problem is either something very simple (i.e. a setting random advanced configuration). I read somewhere as you will need to 'install' the router on the system, and that is not "plug and play" as Sky Broadband seems to have deduced by phone... but I would have thought the installation CD has done this, as when I discovered my connections (when the Ethernet cable is plugged in), it recognizes the connection (it won't only ++ anything). If there is no specific process I need to follow in order to properly install the Netgear router (for which I am currently trying to see if there are appropriate drivers, I need to download), I'd appreciate a lot of the age of enlightenment! It could also be a question that I need to reset the network key in the security settings of the router, as there are already three computers in the House connected to the network... but of course I can not do without first sorting on why my laptop can still communicate with the router via the Ethernet connection.

  Points to note:
  -My laptop runs on Windows XP Professional Version 2002 Service Pack 2
  -The disc to install Sky Broadband installed Internet Explorer 7. the last time I was online, I think that I was still using 6.

  If anyone could be of any use to solve this puzzle, you have earned yourself my eternal gratitude!

• 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,

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

• Unable to create the new network former TC

  Hello

  So I have the current generation of TC acting as a router as well as a HDD on my old to wide wireless broadband. I experienced some problems with connectivity recently (where my MacAir shows that I am connected to the internet, but no matter what site I try to access everything simply does not load and ends up with a progression of Ribbon on the address bar of Safari-turn off and turn on the power back constantly solves the problem), but this is not what I am asking today. Recently, I had the new optical fiber internet for my house and got a new modem and everything has been installed. Only one of the four ports in the modem seems to work, but at least it works. The D-link router that came with it works fine, but I want to use my TC as the router instead. However, whenever I connect the TC on the working port, I am unable to connect. Airport utility, the lights of TC in green but 'Internet' is yellow, i.e. does not work correctly. It should be a problem with the TC because the D-link router works on the same port and connection ethernet via a thunderbolt on the same port adapter works perfectly fine as well.

  Is this a problem with the old settings on my TC being incompatible with the new network? Please advise, thank you very much!

  There are at least 2 different issues at stake here and possibly 3.

  A question is that whenever you change the modem or the router that connects the TC, or your provider of Internet services, the TC must be reset back to settings by default, and then set it up again to work properly with the new product and the new service.

  You don't mention how old your 'old' Time Capsule can be, but 3 years is on the average life of the time Capsule, if anything more than 3 years will be suspicious where reliable operation.

  The third possible cause is that only a single port of your modem/router works when the four should work. If this is a real problem here, we can't say, but you have to wonder a little about the reliability of a product that doesn't seem to work properly
