In windows 7 when I connect a PLC through ethernet it shows network not identified even if I get a response from device when I ping

I put the ip ethernet for the laptop like 192.168.1.5 and PLC as 192.168.1.24. The same thing has been done under Windows XP, PLC was communicating with laptop with Wndows XP but not in Windows 7.

  • Windows 7 Media Player 12.0.7601: album art don't is not displayed even if the column is selected and album art is saved on the drive

    I just loaded all my music from my Windows XP system on my Windows 7 system.  Each album has album art that appears in "now playing".  But when I opened an album in library view and list titles, album art is not displayed even if she is among the columns selected to be shown.  All other columns appear and disappear depending on whether I choose them, but the album art is not.

    How to display album art?  Please don't tell me to switch to playback.  It is very unpleasant for me.  Even if the album art is displayed there, the space that is takes 2/3 of the screen to keep a small image of the cover of the album.  The list of receives securities only 1/3 remaining, so there is not enough space to display more than the name of the track, rating and length.  In addition, I don't want to see the sides, but they show that even though I have deselected this column.

    Windows 7 SP1 running Windows Media Player 12.0.7601.18741.

    HI - in the library WMP view did you check the setting on the box highlighted in yellow in the screenshot below? (Depending on which section you are in you need to 'extended tile' or 'icons')-R.

  • Network not identified in Windows 7 Ultimate error

    I brought my laptop (a Dell Inspiron 1545 running Win7 Ultimate Edition) sleep tonight to find out the formidable network no error identified to connect to wireless networks. (The others are able to connect to the same network without problem). I took the following measures to solve the problems:

    Network resets (netsh int ip reset, netsh winsock reset, netsh advfirewall reset), don't reboot, no good
    Reinstalling the WIRELESS card driver (also not confirmed any newer driver version), don't reboot, no good
    Network card wireless confirmed the acquisition value of IP/DNS by w/IPv4 DHCP information
    Stop the Bonjour service, not good
    Hello uninstalled, reboot, not good
    Uninstalled VMWare Player and virtual adapter associated, reboot, not good
    Run the network, not good troubleshooting
    System Restore ran for a couple of days before the problem occurred (so resettlement of what above), not good
    Minimum by http://support.microsoft.com/kb/929135, not good boot

    I'm full of ideas here. Any help?

    I had exactly the same thing with my Acer 5342 G.  I did everything you did, and I was getting really frantic when on a whim, I uninstalled my McAfee anti virus suite.  Problem solved immediately.  the hardest part now is get McAfee to own up to the fact that it might be their software.  I'm not sure this will help, but I really hope it does.

  • Taskbar Windows 8 says network not identified but computer identifies TI-no internet connection

    My taskbar to the laptop says "Unidentified network, no internet access", but when I click it, it opens the list of network connections and shows that I am connected to my network wireless home (he identified) and there is no notice of limited access. This seems very contradictory. I had no problems until last night when my roommate connected his Mac via the wireless to access Netflix and press the factory reset button on the wireless router. She got in line without problem, but now I can't. I'm done with my iPhone to connect with the wireless and my laptop off the phone running hotspot. I would like to move directly from the wireless, without going through my iPhone.  I can't access Internet and instead of my computer on my network to laptop, I renamed as a media player and not only as my old computer in my office (it is his link showing?). When I try to go online the page shows not connected to the internet, and I click on troubleshooting. It says restart the router/modem but I did that five times and nothing changes. I restart my laptop too. It's been hours now and I "restored" my laptop to an earlier point. She can get online and the wireless router, the lights are all green as well as do? Am very illiterate when it comes to this computer stuff and most of the answers I've seen online that I have no idea what they are talking about - IE. Change of IP address, system configuration, etc., so be very, very aware and make your answers as if you're talking to a fool. (You're) And if you could give me instructions step by step - as the right or left click here or I would be SO grateful. In desperation right now. Thank you.

    Hello

    Welcome to the Microsoft community. I appreciate your efforts to resolve the issue. I will certainly help you with the problem you are experiencing.

    I would like to ask you:

    • How did the other laptop connected to the router? Is it cable connection or wireless?

    If the other laptop is connected with a cable, so that the issue could be with the settings of the router. Therefore, you should contact the Internet service provider in this case that the router has been reset. If the wireless connection on all devices and you are not able to go online using your laptop Windows 8, follow these steps:

    1. Open the start screen, type CMD.
    2. Right click on command prompt, and then click Run as administrator.
    3. Type the following commands and press ENTER after each command.

    netsh winsock reset

    netsh winsock reset catalog

    netsh int ip reset c:\resetlog.txt

    ipconfig/flushdns

    If the problem persists, visit the computer manufacturer's website and download the latest drivers for network / wireless and install.

    Hope this information was useful. Let us know the results once you have tried.

  • Windows XP - want to connect to a remote printer on another network

    I'm in an office that wants to connect to a remote printer on a separate network to our warehouse on the internet.

    Office network is behind a switch, the warehouse network is on a router, both computers we want to connect using XP.  The printer in the warehouse is currently connected directly to the router, but we can connect to a computer by USB.  The two networks have static IP.  We would like to have the printer of the warehouse are displayed on the office computer printers and fax machines as just an another printer if possible.
    I tried to set up a VPN without success and tried LogMeIn but a client computer cannot print to host apparently (and we want that no interaction with the computer of the warehouse on-site, just be able to connect from the desktop).
    Is there a better solution for this?  Anything is possible with remote desktop?  Or should I continue to try to put in place a VPN?

  • (this is the 2nd attempt) I have SP1 with first Home Ed. I have received no Windows Update since 11/11/09. I have no error reporting and no problem, I just get a response that my system is up to date.

    Redshift905,
    If you know if you're missing the updates?  Usually if you run Windows Update and it says that your system is up to date so that means that he has not found the updates apply to your system.  If you think that you get the updates, then you can reset Windows Update components and test again.  Here is a link with instructions if you want to do.

    Greetings Dani56777,

    Thank you for using communities Support from Apple!

    I understand that you run Windows 10 and you must update iTunes to the latest version so that your iPhone will be recognized when connected. I do not know if you receive an error when you try to update iTunes or not.

    If you need information on how to update iTunes, please follow the instructions in the following link.

    Download the latest version of iTunes for Windows - Apple Support

    If you receive an error or alert, you can consider removing iTunes and all of its associated components and then reinstalling fresh iTunes on your computer. That would give you the latest version of iTunes. If you need execute this process, please follow the steps described in the following article.

    Remove iTunes Control Panel and its associated components

    Use the control panel to uninstall iTunes and software components in the following order:

    1. iTunes
    2. Apple Software Update
    3. Apple Mobile Device Support
    4. Hello
    5. Apple Application Support 32-bit
    6. Apple Application Support 64-bit

    On some systems, iTunes can install two versions of the Apple Application Support. What is expected. If both are present, do not forget to uninstall both versions.

    Do these elements in a different order, uninstall or uninstall only some of them. This could have unintended effects. After you uninstall a component, you may be asked to restart your computer. Wait to restart your computer until you finish remove all components.

    Remove and reinstall iTunes and software for Windows 7 and later versions - Apple Support components

    Have a great day!
