My local network works, but why I can't ping? LAN works but not internet. A simple quest to the Jedi.

Hi all!

I have weird problem and I hope some of you can enlighten us if necessary.

The background:

My OS is Windows Vista Home Premium SP 2.   One day, I installed an application proxy - ProxyCap - as a free trial for 30 days.  The application installed a few dll Winsock provider.  After the 30 day trial, I uninstalled the app.  Then the problems started.  Even if the application proxy has been disabled, regular internet links have been completely normal and not affected.  It was only after uninstalling the app that I have problems.

The problem:

  • The computer is unable to connect one more to any website using the browser.
  • My local network seems to be fully functional, which involves a problem of setting the software.  I say that my LAN is functional if I am going to sign--> Network and Sharing Center--> view status and look under the "Activity" section, I see the link send and receive packets without problem.
  • If I go into control panel of--> Network and Sharing Center--> view status of--> diagnosis, I get the message: "cannot communicate with DNS Server (xxx.xx.xxx.xxx) Network Diagnostics ping to the remote host, but has not received a response."
  • Indeed, if go to start--> cmd and ping my DNS server, I get a general failure for all 4 packets sent.
  • However, I am able to ping my localhost to 127.0.0.1

My settings:

  • My ipconfig/all output: http://pastebin.com/Ksn2k2ja
  • DHCP is enabled.
  • For the properties of connection LAN--> Internet Protocol Version 4 (TCP/IPv4)--> properties, I 'IP automatically get an address' and "Obtain DNS server address automatically" selected.
  • The same goes for--> Internet Protocol Version 6 (TCP/IPv6)--> properties.
  • The Sysinternal autoruns--> tab providers Winsock application, tells me that I have the "Hello Namespace Provider' active as a WinSock2 registry entry. It is mdnsNSP.dll and published by Apple Inc..  Who was present before installation of the proxy, and this is for iTunes.  Screenshot: http://i1300.photobucket.com/albums/ag86/applemeetworm/winsock_zpsb41ca872.jpg

What I tried:

  • I tried to reset Winsock for Vista by clicking Start--> cmd and type netsh winsock reset , and restart the computer.
  • I tried to reset the TCP/IP stack by clicking Start--> cmd and type netsh int ip reset c:\resetlog.txt and restart the computer.
  • Restart my router.
  • Deactivation and activation then my connection to the local network.

Thank you all for helping me with my problem.  I would be happy to provide more information as needed.  Thanks for the research and thanks offering solutions.

See you soon!

Hi all!

I contacted ProxyCap and support staff has been able to solve the problem.

Apparently, one of my entries in registry Winsock2 (Winsock2, Namespace Catalog5, 5 catalog entries) has been disabled somehow, uninstalling or in my first attempts to address issues after uninstall.

Thanks to ProxyCap and for other people who have tried to help.

~ Congratulations ~.

  • Connection to the local network works do not, something seems wrong with the network adapter.

    Hi guys,.

    This week, my HP Pavilion dv 9700 had problems connecting to my LAN. (Windows Vista OS)

    By trial and error, as suggested by my network support, I thought that the problem was the laptop and not on the network.

    After that, I managed to make it work by jumping through hoops like the rotation of the network adapter, reboot the laptop and then restart the map. After three days, that is no longer working and I have the feeling that the network card is simply liked work. (Network appears as Local and unidentified and still keep identification)

    The wireless card does not work, I am posting this from my university network. So I guess that the wireless and ethernet card are separate pieces of equipment?

    These cards can be repaired or replaced?

    I would be happy with all the guidance as a student, I have a little to my internet for everything.

    Yes, absolutely.

    Do a search for USB RJ-45 network adapter. You can get those up to 100 MB connection speeds or 1 GB ot.

  • WRTG54S to connect to the network, but not internet

    I have a WRTG54S and Mediacom 12mbps. My router worked fine on my old laptop (a Dell Vista), he was sitting in a box for about 6 months and now that I have a new (Sony running 7) I can connect to my network, but not internet. I have updated the firmware of 7.6 to 7.8 without change. I have tried no security, wep and wap without change. Also, I cloned the MAC, once again no change. Windows cannot detect all problems, and when I try to activate the router to connect to the internet it always says connection failed. I can connect directly connected to the modem but not when connected to the router or wireless. Any ideas? Thank you

    Problem solved. I had to go to a Motorola SurfBoard 4100 to a 5100. Thanks anyway

    Vodkaholic27, let me start with the layoff of vodka for a bit and then set Virtual Machine network card to bridged and then assign a static IP address that is appropriate for the guest as the physical LAN operating system is the host.  Then in the local physical network for static IP address router you assigned in the guest OS configure it to allow Port Forwarding on the appropriate port.  Then, you will be able to access from outside local physical host network.  If it's just on the other system on the physical LAN to the host that you want to access the guest you need not set up the Port Forwarding on the router on the local physical host network, simply use linked by a bridge to the network adapter in the Virtual Machine.  If you use NAT to the NIC of the Virtual Machine, then you need to set Port Forwarding in the virtual network Editor.

    Note: The virtual network Editor is not installed by default in Vmware Player 3.x and later versions.

    ==========

    To install the missing virtual network Editor, the command prompt:

    VMware-player-*.exe -e c:\vmptmp
    

    Then in the c:\vmptmp folder find the file c:\vmptmp\network.cab and extract (double-click on the .cab file) vmnetcfg.exe (virtual network editor) file in the working directory of VMware Player usually 'C:\Program VMware Player' or ' C:\Program Files (x 86) \VMware\VMware Player.  You can create a shortcut and place it with the shortcut of VMware Player, if you want to access it more easily.  Note: there are some for all the files to be extracted to then access the network.cab file.

    It is a security error Chrome because of its policy of origin even on local files.

    1. the first thing to do is to make sure that the computer is completely virus/malware-free. Googling around this error produced quite a few links where the posters were or had been infected with Spyware Protect 2009 rogue.

    Once the scanning is complete (do not skip the preparatory stages no more), if the problem persists:

    2. double-click on my computer, right-click the icon for your hard drive, click left to get its properties. If you see options to set Quota management make sure that they are disabled.

    3. in the case - BUT ONLY AFTER YOU ARE sure THAT THE MACHINE IS MALWARE/VIRUS-FREE - copy the lines between asterisks (not including the asterisks) below and paste it into Notepad. Save as undopolicy.reg somewhere, you will find. And then double-click the .reg file, that you have just made to melt in your registry. I hope that this will take care of the issue.

  • Windows 7 computer to connect to Airport Extreme with an external USB drive attached. Flash drive appears for the network map but not the hard drive.

    original title: drive hard extreme airport

    Using Windows 7 and the Airport Extreme.  The Airport Extreme has a USB port that can be used to mount an external hard drive which is accessible via the wireless connection.  Only thing is, I can't get a 2 GB flash drive will appear for mapping.  When I use the other hard drives, they never show upward for mapping.  They show that it is connected to the Airport Extreme, but are not seen by my PC.   The internet has a rumor according to which hard drives will show up only on a PC if they are to FAT32... which would work without another formatted hard drive.  What do you know about my problems of compatibility with hard drives?

    Hello

    Check updates firmware for the Airport Extreme.

    Airport Extreme
    http://www.Apple.com/WiFi/

    Airport - Support
    http://www.Apple.com/support/airport/

    ---------------------

    Although I think that the question is really the Airport Extreme also updates Windows 7 WiFi.
    Check with the system manufacturer and the real device manufacturer updates the driver.

    Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
    version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
    Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
    http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

    Installation and update of drivers under Windows 7 (updated drivers manually using the methods
    below is preferred so that the latest drivers from the manufacturer of system and device manufacturers are
    found)
    http://www.SevenForums.com/tutorials/43216-installing-updating-drivers-7-a.html

    Download - SAVE - go where you put it - right click – RUN AS ADMIN.

    You can download several at once however restart after the installation of each of them.

    After watching the system manufacturer, you can check the manufacturer of the device an even newer version.
    (Those become your fonts of rescue system manufacturer).

    Repeat for network (NIC) card and is a good time to get the other updated drivers as windows
    7 love the updated drivers.

    I hope this helps.

    I have a Folio that worked very well in Local mode. After having moved to the cloud, and downloaded to the iPad, the functions are either broken or irratic.

    It was originally built during the last few days and has been updated in the last 24 hours - then the trouble started.

    I have noticed various comments on the recent troubles Folio Builder and have v7.0.5.17 on CS5 with whatever the last Adobe Content viewer (installed yesterday). Mac is 10.7.2.

    I deleted the Folio of the cloud this morning and again largely improvements articles from scratch, re-uploaded, then to the back for iPad - but not joy.

  • My address bar doesn't have AutoComplete. Windows XP and it worked but not now. How to start the AutoComplete?

    My computer crashed and it was restored. I am running Windows XP and I do not re - install Firefox Aurora after the computer has been restored with the new motherboard and HDs. All my software works, but the AutoComplete is not the case. Firefox remembers my username for login and my password. It's just the AutoComplete. I have to tap completely in the name of the site. When I opened the window of the history and bookmarks, there is no entry. The yellow star in the address bar does not work. When I click it, nothing happens.

  • Work wireless, but not Internet

    I use a WRT54G Router.  I am able to connect to my home network via the wireless but no Internet on any of my wireless devices.  It works only via Ethernet.  The firmware version is v3.01.3.  Any ideas what I did wrong?

    Hi mullahraheil, to properly isolate the problem, try changing the name of the network wireless and communication channels. Try the channels 11,9,3 or 1. Try to reconnect. If the same persists, you need to maybe do a hard reset on the device and reinstall it from scratch.

    To make the correct reset, please press the reset button at the back of the router for 30 seconds when the unit is turned on. Unplug the unit. Reinstall everything from scratch. Hope that helps.
