Disappearance of wi - fi

My laptop loses its wi - fi connection broadband sooner or later (a few minutes or sometimes 10 or 15 minutes) after the connection is established. I can usually restore the connection by going into my Control Panel Windows and choose to diagnosis and repair within the sections of the network . The problem is identified as cannot communicate with primary DNS (192.168.1.1) Server and the proposed solution is to reset the network adapter "wireless network connection" mode I click on, so that the connection is "repaired" and restored. Normally, the connection remains good, but if I'm still working with him for more than 10-20 minutes sometimes, the connection fails again. The problem does not lie with the router; other laptops with the same connection don't lose. Is there something wrong with my laptop I could fix it?

  • The music disappeared from my library

    A few months ago, I bought an album and today, I noticed that most of the songs on the album had disappeared. I went to the store and saw that it was as if I had never even bought the album.

    What can I do?

    If it does not show in the section bought for redownloading you have checked to see if you have the hidden cloud: hide and expose the purchases made on the iBooks Store - Apple Support, App Store or iTunes Store ?

    If the version of the album you bought is no longer in the store, or if you have moved since the purchase, you can re-download if you no longer have it on your phone, or your library computer iTunes, you will need to copy backup your computer back.

  • iCloud Contacts disappear from Oultllo after updates

    After I have updated recently iCloud and Windows 10 (update of the anniversary) my iCloud Contacts disappeared from Outlook 2007, giving the following message appears in Outlook by clicking Contacts iCloud: "failed to open all the files. The information store could not be opened. "When clicking on tools-address book in Outlook, the following message appears:"unable to display the list of addresses. The Contacts folder associated with this address list could not be opened. It may have been deleted or you do not have permissions.

    Everything worked fine before the update and the address list is in my iCloud contact account and is accessible by my iPhone.

    I tried to export a vCard in iCloud for import in Outlook by going to the Menu Action to iCloud and selecting 'Select all' and then 'export vCard', but no window never opens in which name and save the file.

    As a last resort, I could probably restore the old file of Contacts if I knew where she stood in Outlook.

    I tried many suggestions but nothing worked. Someone has any idea how to restore the iCloud Contacts file in Outlook?

    Thank you

    See if it helps, - the set of folders could not be opened. The information store could not be opened.

  • Disappears from the status bar

    When I'm away from mobile data my status bar disappears.

    What mobile data?

    Try resetting your device. This will not erase your data stored on that device.

    • Press and hold the sleep/wake button
    • Press and hold the Home button
    • Press and hold both buttons until the display turns off and on again with the Apple logo on the subject.

    Alternatively, you can go to settings - general - reset - Reset all settings

  • Remove photos on the importation of the iPhone disappeared

    After this last update of OS X El Capitan loading 10.11.6, the ability to delete Photos after importing my iPhone disappeared from the screen.  It imported, but left on the phone.  Now I have to remove it manually from my Camera Roll.

    You can open the Image Capture and remove them at once instead of delete both on the iPhone.

    Just connect your phone and Spotlight for the Capture of the Image search, then click on your iPhone.

    Not sure why this option isn't for you. It appears on my computer and my wife.

  • Reminders will not disappear.

    Since the upgrade to Sierra, I've got two callbacks that will not disappear. I have mark complete and they immediately pop up again. They are not yet listed in the application of reminders or calendar, so I have no idea how to get rid of them. Any suggestions? I don't want to disable notifications entirely for reminders that I use frequently.

    I had this problem too. Signing on and to iCloud it resolved for me and no more iCloud related issue.

    Good luck!

  • Problem with SMTP servers that disappear

    I've recently updated to the official version of Sierra.

    Since then, I can't send mail more.

    I have a special setup in Apple Mail: I config a manual counting that iCloud as IMAP for receiving server and Gmail as SMTP server to send. That allows me to have sort of a double synchronization with iCloud and Gmail.

    It was working perfectly until that date, but after Sierra upgrade it keeps losing my SMTP server config.

    After some instructions on mail and Sierra problems (in this thread: Re: IMAP e-mail accounts went into Mail after upgrade of Sierra), I have built my mail again, created new account, but the problem remains.

    What happens is that it continues to lose my SMTP server. I re-entered 20 times or more, save, but she mysteriously disappears. I go to Mail > Preferences > accounts, select my manual counting and this is what I see under "server settings":

    Password is missing. Username loses the game ' @gmail.com ' email address and authentication is set to None.

    If I'm in all the fields correctly, switch tabs, back: it's all gone!

    I tried to remove the smtp server and create a new one, but the same happens.

    All faced a similar problem? Do you have an idea how solve it?

    Thanks a lot for help.

    Gabriel

    I have a special setup in Apple Mail: I config a manual counting that iCloud as IMAP for receiving server and Gmail as SMTP server to send. That allows me to have sort of a double synchronization with iCloud and Gmail.

  • Mail attachments disappeared with Sierra

    After upgrading to the Sierra, attachments disappeared for all my encrypted emails (mime).

    I don't see anything, just a question mark instead of the attachment in each email.

    With a backup I re-imported again the mails, but it has not changed anything.

    Is a bug of Sierra-ti? How to solve it?

    More information:

    I opened an e-mail with an attachment directly copied from my support of El Capitan and opened in the Mail of Sierra of doublecliking application. It worked perfectly, the attachment was visible.

    I searched the same email in the Mail of Sierra application and attachment was more readable (just a question mark appears instead).

    Conclusion: I thing that during the import of mailboxes, mail of the sierra is corrupting part of emails (.emlx) who are after import not more readable!

  • Best sites to keep disappear once history of safari is disabled

    I'm trying to put Hotmail and my work see connectivity service as my best sites, but every time I clear history in safari that they disappear. It is only on these two sites that make others seem to work well.

    Any advice? Cheers.

    Hi Aur0xx,

    Welcome to the communities of Apple Support!

    We understand that you are trying to add Hotmail and your workplace for your Safari Top Sites, but when you clear Safari history, these sites disappear.

    The first article below explains that Top Sites that are not marked as permanent will be deleted if you clear the browsing history Safari.

    Safari for Mac: delete your browsing history Safari

    This article explains how to maintain a website in Top Sites.

    Display your Top Sites - using Safari

    • Keep a site up to the Top Sites: Hold your pointer over the thumbnail of the Web site, and then click the PIN icon appears. To unlock the site Web for Web sites can be replaced, click the PIN icon again.

    Once you have Hotmail and your workplace configured to appear constantly in the Top Sites, Safari history resetting shouldn't delete these sites.
