Lost my wireless after upgrading

After upgrading my Airport Extreme to 5.3.1, i have lost my wireless connections. I still have my wired connection through the router, I can't seem to re-establish my network through airport. I have even reset the airport by pushing the button. Restarted my cable internet connection x 2 and restarting my computer, recycling the Airport Extreme...nothing is working wirelessly. Maybe my Airport Extreme is broken?

Try deleting the following files from the ~/Library/Preferences/ directory (this is the Library directory within your User folder):
* com.apple.internetconfig.plist
* com.apple.internetconfigpriv.plist
* com.apple.internetconnect.plist
go to to Airport menu and re-selecting the desired network.
*perform a hard reset*

Also, merely unplug the Base Station and then plug it back in after 30 seconds or so. I've also experienced this same problem on a very infrequent basis and recycling the AEBS always permitted it to be recognized again by Apple's Airport Utility

Has anybody lost imported photos after upgrading to Lion? (iphoto11)

Has anybody lost imported photos after upgrading to Lion? (iphoto11)

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

Lost Developer Toolbar after upgrade from 4.1 to 4.2

After upgrading from 4.1 to 4.2.1.00.08, we have lost the Developer Toolbar.
Have others run into this with the upgrade or fresh installation of 4.2.1?
If so, what suggestions are there for fixing, short of reinstallation mentioned in this other thread:
{message:id=10692572}
Following the guidance there to look at the instance ID and other preference settings, I compared our three instances. The two that are not having the problem are both at 4.2.0.00.27.
Here are the preferences that exist on our other instances but are null on the problem instance:
APEX_4_1_0_PATCH_12920544
APEX_4_2_0_PATCH_14777994
APP_EXPORT_TO_DB_ENABLED
HPROF_DIRECTORY
INSTANCE_ID
MOBILE_DEVELOPMENT_ENABLED
PRINT_SVR_HOST
PRINT_SVR_PORT
PRINT_SVR_SCRIPTI have asked our support team to review the upgrade log. Re-installation from scratch is an option.
Any advice is welcome.

Thanks, Joel.
You inspired me to take a closer look, and look beyond the upgrade.
After the upgrade, my application passed a superficial checkout. Later, I exported my application and in the export file, the Instance ID was not NULL. I had not noticed any problems with how APEX was working.
The problems of the missing Developer Toolbar, Instance ID = NULL, and a new one, did not occur until I removed my application and tested a clean installation of the workspace and application. This is the sequence of events. The immediate triggering cause is clearly one of the following:
1. Deinstall application (ID 820) from APEX 4.2.1.00.08 instance, running 11g (11.1.0.7.0).
2. Remove workspace (PVA_AH9_R12)
3. (drop the parsing schema, xxpva, and related tablespace)
4. (create tablespace and schema user, xxpva)
5. Import workspace (PVA_AH9_R12) from an APEX 4.2.0.00.27 instance.
6. Import application (ID 820) including supporting objects from an APEX 4.2.0.00.27 instance, running 11g (11.2.0.1.0).
The next day I noticed the Developer Toolbar missing problem, and found that Instance ID is NULL.
Also, after Exporting an application in Database format, I cannot download the file from the Export Repository. When I click the filename link, I get 'Access Denied' instead of the normal download dialog.
Does this suggest anything else I should look into?
Do you think I should post this as a new problem/question with more detail about the sequence of events?

ICal has lost all events after upgrade to 10.8.3.

iCal has lost all events and calendars except for birthdays after upgrade to 10.8.3. If I sync to my iPhone, will it wipe them from the phone, or will it get the events from the phone?
I have Time Machine working, but am unsure how to restore calendars from it.
PLEASE HELP.

Not sure why you think having to re-authorize would indicate an incompatibility or problem with their software unless you meant you have to keep re-authorizing the plugin?
Some plugins need re-authorization when you change a certain file or files in your system.. or if the file structure itself changes.. or the drive is renamed for example.. It could simply be that IK used a different form of authorization routine to their other plugins or versions of their plugins, with Amplitude 2.... Nothing to do with an incompatibility...or problems.
Anyhow I am happy you got the matter resolved and yes, random bursts of white noise is a classic sign of a plugin running in demo mode and needing authorization or re-authorisation as I suspected in your case.

Lost my music after upgrading to iOS 8

After upgrading to ios 8 I lost all the music downloaded through iTunes (from ripping my CDs), on both iPhone 5 and iPad 3rd generation, except the music purchased online.

Hey Keisha, Are the photos in your iPhoto library on your computer? If so, you should be able to check the photos option in your iPod's summary page in iTunes and add then back. Hope this helps, Cheers.

Lost campass apps after upgraded to ios7

I lost the compass , stocks apps after upgraded, how can I install it back?

All your apps should be in your itunes media library, sync your phone to itunes.
Or directly from your phone - app store - update - purchase - all or not on this phone - hit the cloud next to the app you want to download.

E71 lost calendar notes after upgrade

First I made a full backup with nokia pcsuite and to memory card,and then I upgraded my E71. When I tried to restore I saw that all my date of calendar was lost.
Even with the restore of memory card it was impossible to recover calendar events.
I also have the problem that after upgraded it wasn't possible to see the firmware version with *#0000#.
Only when I switched off and removed the battery it was resolved that problem.
Any suggestions to the first issue?

I have exactly the same problem, on my iphone 3G is now a 'calendar' which is empty. I did not create this calendar it just appear but all the other calendars which I have in my iphone and iCal (iMac Intel) dissapeared, vanished!!
I have tried
disconnect iphone from iMac,reset iSync history on my iMac,
restart iMac, backup all my calendars on my iCal,
delete all calendars on iCal , import back into iCal from backups,
launch itunes, synchronized iPhone ( for calendar on iMac iCal to replace calendar in iPhone)
Nothing, the same , nothing came over from iCal.
Where is the solution ? hopefully that Apple would have more time to look into this iCal iPhone calendar issue, now that they have come clean on the Antenna issue. Apple really do not need another problem Calendargate.
Hope Apple resolve this by this week, I have been spending sleepless hours late in the night, trying everything. Somehow, I think this is a problem with iOS4.0, 4.01

Lost data connectivity after upgrading iPhone 4 to iOS 5. How to fix?

Hello,
I upgraded my 16GB iPhone 4 yesterday from iOS 4.3.5 to iOS 5 and everything went fine after a few failed connections to Apple's servers, however my phone lost the data connectivity completely. Phone and SMS worked fine, I could also connect through wi-fi with no problems, however whenever I tried to use data I got a message that my phone was not signed to an internet service.
I restored my phone from the backup after upgrading. Not successful. I also reset the network configurations. No deal.
My carrier is Vivo (Brazil) and everything worked fine prior to the upgrade (and after the downgrade).
I imagine it can be a problem with APN configuration under iOS 5 and I tried to configure it through a webpage, but I got a message that my phone already had a APN config (profile) and could not install another. Under Settings>General>Network I don't have the "mobile network option" nor the "profile" option.
Any thoughts? So far I haven't contacted other people under my carrier who upgraded to see if they had the same problem.
Thanks for reading,
Samuel

I got a workaround; it's not what I wanted, but it solves the main problem.
I noticed that I only lost data connectivity after restoring from backup after the iOS 5 update. So what I did was to backup my phone, restore again to iOS 5, configure as a new phone and backup again (with nothing in the phone).
Then I launched an iPhone backup utility software, in this case, iBackupBot, which in the trial version is enough for what I wanted. I opened the old backup and exported only the files I wanted (like call history and SMS history), then I imported these files into the new backup and restored from it.
I lost my media files (which I copied before) and some configurations, but the most important itens, like SMS, I managed to export from the old (complete) backup.

HT5361 Lost RSS Feeds after upgrading to Mountain Lion.

After upgrading to Mountain Lion I have lost my RSS feeds.
Is there any way to get them back. When I try to add them again I get the Error "No associated application found".
Thanks

Mountain Lion removed RSS support from Mac OS X applications.
If you want to use RSS, you have to install a third-party application. There are a lot of apps like Reeder, but you can have a look for more in Internet. See > http://www.cultofmac.com/182077/five-ways-to-replace-safaris-rss-reader-in-mount ain-lion/

Lost music files after upgrading to itunes 7

Hi, can someone please confirm whether or not my music files have been physically deleted from my computer after upgrading to itunes 7. Many of the songs in my playlist, including MOST of the songs purchased through itunes come up with the error that the original file can't be found. I've done searches and can't come up with the files.
I want to know if they are indeed gone.
I realize that you click "I agree" to the agreement before installing and as of now this "contract" has held up. However, we'll see how well it holds up when offered software is knowingly removing personal files. I'm sure that if someone were to write a virus that destroys your computer, if it had a warning message with an "I agree" button, it would be a very difficult contract to stand by.
To my recollection, no software in the past has physically removed personal files from your harddrive on install.
So, I don't think a precedence has been set for this kind of class action.

and we refresh.

Lost iTunes Library after upgrading to iTunes 7.7 HELP PLEASE

I have two issues on hand : after upgrading to iTunes 7.7 I opened iTunes and all of my music was gone except for about 1,000+ songs (3.2 GB) when I originally had about 20GB worth of songs. How can I recover my full library into iTunes ?
Second issue: when importing new CDs into iTunes 7.7 it only plays a fraction of each song before moving on to another song, whereas iTunes shows that I have the full song imported.
I really appreciate someone's help here, and does the latest version of iTunes have a bug ??

Further to my last post, I find that the purchased songs have been retained in the iTunes Library of my Mac Book - is there any way iI can restore them to the iMac?

Lost my songs after upgrading to ipad 2

After upgrading to an Ipad 2, then reinstalling garage band, My songs have disappeared. Help.

When you say "upgrade" to iPad 2, does this mean you had an iPad before this one? Because if you just reinstall the app, then it won't have any data on it. You should restore the iPad 2 from a backup from your previous iPad, if you had one.

Lost user data after upgrade bios in G580

HI
I have strange problem with Lenovo G580 with Windows 7. After upgrade bios to newest version and reboot my system start without any user data (no documents, no programs installed earlier), All reboot take short time, about 1-2 minutes. Only username stay the same.
Is it possible that upgrade BIOS was bring recover system to factory?
Does data can I recover somehow?
I need help because there was important databases of company.
Thanks
Dariusz

hi Dariusz,
Welcome to the Lenovo Forums.
That's really strange indeed and very unusual as I've never seen a BIOS update delete a user's data before. Perhaps you're logged-in to a temporary user profile?
To check if you're logged-in to a temp profile, show hidden files and navigate to C:\Users and check if you have an identical username with a dollar sign right next to it and apply this fix:
Fix Corrupt Windows 7 Temporary Profile
For data recovery, check these Free File Recovery Software Programs.
Hope this helps
