HT4628 WiFi network drops after upgrading to Yosemite

Typing into this field white using Safari results in a partial window and completely white font text and it requires me to use another browser.
Ever since upgrading to Yosemite on my MBA 2013, the connection drops, re-searches for the connection, and although it shows a checkmark, it gives a 169.x.x.x IP address.  The only way to reconnect requires turning WiFi off and back on again.  The problem is that it doesn't hold for very long.  I am letting the network admin know about this, but I never had this problem with Mavericks.

I also have the internet diagnostic report, but it is nonsense to me to read it.

  • Can't Login With Network Account After Upgrade To Yosemite Server 4

    I've been putting off this troubleshooting for a while now, and after trying everything I could find, decided to post.
    - After upgrading my server to Yosemite with Server 4, and my MacBook to Yosemite, I can no longer login with any network accounts.
    - I was on clean installs of Mavericks before the upgrade.
    - I'm using SSL for the OD, with a GoDaddy cert, the same one that was working on Mavericks.
    - I've tried removing the laptop's binding using the Users and Groups preferences dialog, which does not remove the laptop's entry from Open Directory, so I manually deleted the record on the server.
    - I then choose to Join again, and it looks as though everything goes through, but I still cannot login with a network account.  Also, when rejoining, it does not create a binding on the server.
    - If I use the Directory Utility->Services->LDAPv3, and add it that way, entering the FQDN and checking Encrypt..., Use for auth and Use for contacts, it asks me for the directory admin username and password, and does in fact create the binding on the server, but I still cannot login.  What's strange about that method, is that it forces the use of the IP address of the server, rather than the FQDN, like I entered it, which would of course have problems, because the certificate's common name is the server's FQDN.  It does not allow me to change from using the IP address, graying out that field.
    - I've also tried destroying the OD and restoring from archive to no avail.
    It looks like many users have hit dead ends with this, with some having success by completely formatting and setting up a new iteration of the server, but I will not be doing that.  However, I'll be happy to try any other suggestions.
    Thanks for your time,

         Okay, I've finally resolved the issue, thanks to the Apple Enterprise tech support team.  I'm thinking they wouldn't mind if I share this information, but I can't guarantee that this will work on your system or, worse yet, degrade your system further.  However, that's fairly unlikely, just make sure you have plenty of backups before you begin any troubleshooting session.
         So I was told to perform the following instructions, which I did, line for line.  The part about closing Server.app seems a given, but I'm not sure why they want you to open Server.app at the the end (maybe taken out of context from some other instructions?).  I did it anyway, but you should be able to begin testing, on a client workstation, right after rekerberizing is complete.  I did, however, need to reboot my client, login as local admin, and then binding would proceed, and network users are able to login again.  The engineer also let me know to expect an error, something like the following: "2015-03-11 21:58:38 +0000 Error synchronizing removal of attribute draft-krbPrincipalACL from record 72519e4c-7ac7-15e4-bd42-10adb1944cbc: 77013 result: 16 No such attribute" - this is apparently normal, and did in fact happen in my experience.
    So here's the fix:
    - Quit Server.app (don’t just close the window)
    - On the Open Directory Server, execute these Terminal commands:
      - sudo mkdir /var/db/openldap/migration/
      - sudo touch /var/db/openldap/migration/.rekerberize
      - sudo slapconfig -firstboot
    - Open Server.app
    And that's it.  I did nothing else on my OD server, just logged out.  Immediately tried binding on my MacBook client, it failed, I rebooted, tried again, it worked quickly, and I'm able to login with network user accounts again.

  • Wired ethernet network disappears after upgrading to Yosemite

    I am a lone iMac on a Windows network, but have connected through ethernet without a problem for years. Since upgrading to Yosemite, however, my network has disappeared. My ethernet is connected, my IP address is the same as before (assigned by DHCP) and I have made no changes to any other settings. The only difference now is that my mapped network drives cannot connect and in Finder, when I click on NETWORK and SERVERS, there is nothing there.
    The company IT guy is a Certified Microsoft dude and he swears nothing has been changed in the network. It must be the upgrade.
    What has Yosemite changed? (The Firewall is off.)

    Found a fix
    When trying to fix a wake failure, I simultanuously fixed the issue with network drives. It is connected to the Preferences.
    Here is how I could solve the problems:
    Press command+shift+c - > Macintosh HD - > Library - > Preferences -> Drag SystemConfiguration on desktop, it's going to make a copy of it (May ask for password, then delete it from the Preferences (which is the initial folder). Shut down, then do a PRAM Reset. If you don't know how to do that :
    After you shut down the computer, locate the option, command, P and R from your keyboard. Press the power button to turn it on and quickly press all four buttons before hearing the first 'power up sound'. Keep them pressend until you hear a second 'power up sound'.

  • After upgrade to Yosemite my MacBook Air does not switch automaticly from wifi to ethernet. How to sloven problem?

    After upgrade to Yosemite my MacBook Air does not switch automaticly from wifi to ethernet. How to sloven problem?

    Have you tried changing the order in Network Preferences pane?
    Open System Preferences/Networks/Click the gear symbol under the service list. Select set service order then drag. If your wifi is above the ethernet move the ethernet to the top. Click ok. Click apply (bottom left) and test.
    Hope this helps

  • Wifi is extremely slow after upgrading to Yosemite

    After upgrading to Yosemite, i have extremely slow connection on Wifi and also Ethernet connecting to the internet. Had no problems with Mavericks and also my other wifi devices.
    Have tried deleting my network configuration and starting again and also have deleted my System Configuration folder with no success
    can anyone help??

    Finally found the solution. Apparently it is as I have guessed. The fault lies with the latest HTML 5 player added with safari instead of flash player to save battery.
    The problem was solved by selection Safari 7.1 from developer option !!

  • After upgrade to Yosemite, drag and drop for files does not work, destination folder crashes.

    After upgrading to Yosemite, dragging and dropping files from one location to the destination folder, causes the destination folder crash. However, copying the file and then moving it works fine.
    I'm not sure where to report bugs, but I figured this would be the best option

  • After upgrading to Yosemite my wifi is not working on my 2011 MacBook Pro. What happened Apple?  Wifi was fine on Mavericks.Yosemite was free. I guess you get what you pay for.

    Why is my wifi not working after I installed Yosemite to my 2011 Macbook pro?

      Keep it connected to the Power for a while.
      Start up in Safe Mode.

  • After upgrading to yosemite, cannot login as mobile user

    After upgrading to Yosemite, I can no longer log on to the Mavericks server as a mobile user. The password prompt is first on the server instead, because only after I do I remove all network connections or disable, I can log in.
    The connection to the server is running AFP. If I remove the binding in the user settings, then it goes without problems. Also, the Sync works to profile server. I create the new binding, I can do this only with no name / password, otherwise it returns an error message.
    What can be the problem? Must necessarily be 4.0 installed Yosemite or server on the server?
    Thanks for a tip!

    Quick tip: try logging in and don't use capitals or spaces in your username.

  • After Upgrade to Yosemite, all apps are slow.

    I upgraded to Yosemite  and all applications are slow.  ( as e.g.. starting to type in this box give me beachball for 2 seconds initially) A big difference in speed from Mavericks to Yosemite. Opening system preferences takes 3 seconds to load, and clicking on Users & Groups takes 25 seconds to open.
    I do not have fire vault enabled.  I did a safe boot and some apps did appear to open faster. Also did a repair disk and rebooted.  No change. When Safari is open it takes 5 seconds to open a new window.   I ran EtreCheck and the report is as follows;
    Thanks for any help;( After pasting the EtreCheck text file, I clicked on this box to add the Thanks... , it took 2-3 seconds for the beach ball to stop spinning.)

    You could do that, but when setting up your new iMac it is a much better idea to transfer only your existing User Accounts. In other words when Setup Assistant appears, de-select "Applications", "Computer and Network Settings" and "Other files and folders". That way you will eliminate the possibility of reinstalling potentially incompatible software from your existing Mac or its TM backup. It's best to create new printer queues and preferences anyway.
    Your venerable HP 1012 will probably work without any difficulty but if you need its driver download it here. If it gives you trouble try OS X's generic PostScript driver.
    After configuring your user account, install original versions of your essential software from their original sources. In other words if you installed them via download from the developer's website, download them again. You might need license keys so gather them. Obviously the Mac App Store makes things easy since anything you obtain from there is already linked to your Apple ID and is easily reinstalled by going to your Purchases page.
    Don't reinstall things like AppCleaner, CleanMyMac, Western Digital "Smartware" or any of that junk. You don't need it. MacFUSE is outdated. Research Prolific Technology for potential updates for their serial controller. The one you have may work, or not, but you should re-download its driver.
    Consider abandoning Microsoft altogether and migrating to better solutions such as Pages, Numbers, and Keynote. They are all free with a purchase of a new Mac and are far more integrated with OS X than anything Microsoft will ever be able to accomplish.
    The Burr-Brown USB device is unknown to me, so research TI's website for support if you need it.
    If your essential software was distributed on optical media, you can use OS X's "DVD or CD sharing" feature to remotely mount the older iMac's optical drive so that you can install its software. It will work as though that drive were physically installed on your new Mac. Having said that, anything that was distributed on optical media is highly likely to have been outdated a long time ago.
    If your essential software is old, orphaned, no longer supported, or is no longer available, meaning you have the only viable copy, the only option is to transfer it from the TM backup or older Mac. In that case be very cognizant of the likelihood for incompatibility, and have a plan for uninstalling it should it cause adverse effects. Creating a new TM backup is the way to do that. A new external HD dedicated to the new Mac is a cheap investment. When you are certain you no longer require the older Mac's TM backup, you can erase it and use it as an additional, redundant TM backup or "clone" repository – whichever you decide is best for your backup needs.

  • I cannot update apps after upgrading to Yosemite. Please Help!

    Hello,
    After upgrading to Yosemite, i wanted to go on to iMovie, but i have to update. So i try to update but it refuses and tells me: "This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled."
    So what i understand is because i bought this mac in the US and I'm using it in the UK its not letting me update it. But what i don't understand is that i was able to upgrade to Yosemite with my mac knowing i was in the UK.
    How can i update my applications?
    Thank you for your time,
    TOAOMA

    Perform the following, stopping with the first one which works:
    1. Open the Mac App Store's Purchases tab. If you're prompted to accept it and the other iLife/iWork applications into your Apple ID, do so.
    2. Move them out of the Applications folder(they may need to be put into the Trash temporarily), and then see if you can download them for free from their individual product pages. If you're asked to buy them, see #3.
    3. Click here, contact Apple, and wait for a response.
    4. Buy them.

  • Fix for iPhoto after upgrading to Yosemite

    After upgrading to Yosemite I was unable to open iPhoto. I moved it to Trash (do NOT empty trash after moving it here!!!) - then go to App Store and download iPhoto. You'll want to make sure you then go to your Finder and click on the iPhoto download app in order to complete the download. When you open iPhoto it may say you need to upgrade - go ahead and do so then your photos will appear again with a new icon in your dock (remove the old one since it won't work now - the new icon will look different if you had an older version of iPhoto).
    Hope this helps!

    Ok so here's what you gonna do. (had this problem myself today, and after some fiddling figured out what to do.)
    Find your old iPhoto with a cross through it, right-click it and select 'show package contents'. A folder will open. In that folder go to Contents>MacOS and there will be three little things there. Click on the one called 'iPhoto' and terminal will open. Leave terminal open and wait four seconds and VOILA! iPhoto opens. Leave terminal open until you are finished with iPhoto, because if you close terminal, iPhoto will close with it. THX! ENJOY! Hope it works.
    P.S.
    You can close terminal once you close iPhoto. I also suggest backing up your iPhoto library while you can.
