Windows 7 or 8 shows the wireless client connected to the access point, but the wireless icon displays "no internet connection".

I saw the same problem with a different providers wireless solution. When I've sniffed the air with OmniPeek and the network that the ap was conducting with WireShark, I see the arp for the gateway request going to the router, the router gateway response is sent to the suspect machine in the air, the acknowledgement of PC than the package but never fills the arp cache. I watched two arp responses in a vs work for lack of scenario, the two packages are the same.

The only way I could solve it was to disable IP Helper (not start too) services, reboot the machine. I see 3 to 4 drops per day, but since the deactivation of this Service the machines with that I tested have not seen the question once again.

IP Helper:
Provides tunnel connectivity using technologies of transition IPv6 (6to4, ISATAP, Teredo, and Port Proxy) and IP-HTTPS. If this service is stopped, the computer will not have the benefits of improved connectivity offered by these technologies.

Machines tested and fixed:

Lenovo E540
Lenovo W540
Acer Aspire One
Dell Latitude E6420

Ip assistance service has been changed about 40 laptops, a dozen of which would fail in about an hour. So far, 0 out of the 40 saw the question since this change and reboot (reset is the key after disable it) laptops. It's been about 5 days.

Any reason why disable this Service solves the problem? With it I can replicate the problem pretty quickly on a few different types of machines so it seems not to be driver or provider specific wireless network card. I checked through the Event Viewer logs, but nothing seems to be triggered during the show. Using the Troubleshooter or disconnect the wireless service will fix the problem for a short period only.

    If you would please provide details on the game you play?  Also, have you tried to hit F11 and attempt to place the game in Mode full-screen.  In addition, check with the OEM of the game to check if there was an options in the game to use Mode full screen.  I hope that this information is beneficial.

  • After WSUS downloaded and installed the most recent Windows XP and 7 updates, we encountered the following error: page of the Intranet Web displayed in Internet Explorer (8 or 9) is on SERVER_A

    After that WSUS installed and downloaded the most recent Windows XP and 7 updates, we encountered the following error:

    The Web page of the Intranet being viewed in Internet Explorer (8 or 9) is on SERVER_A
    and the page contains a link to a file on a network share on the Serveur_B, making the href path something like
    'http://SERVER_B/myShare/myDocument.doc '.
    ... then it does NOT work.

    If the Intranet Web page being read in IE (8 or 9) SERVER_A on
    and the page contains a link to a file on SERVER_A, making the href path something like
    'http://IP..ADDRESS/myDocument.doc '.
    ... then it does not work.

    Before these updates, the system worked flawlessly.  We try to identify the update that caused this problem, but 28 of them fell on a Tuesday.  (22/11/2011).   These questions are the same with IE8 or IE9 and WindowsXP and Windows7.

  • All of my Windows Vista programs appear under the same icon.

    Problem with Vista programs: all of my Windows Vista programs make their appearance as the same icon.  How can I fix it and what happened?

    Rebuild the cache icon as follows: http://www.vistax64.com/tutorials/117229-icon-cache-rebuild.html.  That should take care of the problem.  I don't know why it happened - but I've seen it before, and we never really determined the cause then either.

    I hope this helps.

  • Windows 7 pro 64. The desktop icons won't stay where I put them. After a reboot, the desktop icons are always rearranged.

    I've set up my office while I have the following icons down the left side of the top in the following order: computer, network, System (C), (D) options, reader of DVD (E), trash.

    Whenever I restart my computer, the icons are rearranged as: computer, network, trash, reader of DVD (E), options (D), System (C).

    I don't want to add all the new icons on the desktop, because I know they won't stay where I put them. When I was using XP it would happen only when I changed resolution but with Win 7, it happens every time that I reboot.

    Reorganization of auto desk is off, snap to grid is turned off, sort by has verified. I use two monitors. All the gadgets that I have in my hand right 2ndary monitor are stay in place very well. The icons gives me the problem are on the left side of the left main screen.

    I made an image of my hard drive just after the installation of windows 7 and before to install the drivers of manufacturers and updates of windows.

    Today, I restored this image, reinstalled the drivers from manufacturers and made the updates of windows. The problem seems to have disappeared now.

    I am re-imaging my hard drive after you install the complete driver/updating. I hope I don't need to use it, but I will if I have to. I still don't know what caused it in the first place, but at least now I have an option of fast food if it happens again. I'll recreate the image on the hard drive after all major software install from that time, I have two images. A fundamental right after pilot installations and one after each installation of software.
