Lost wifi sensitivity after upgrade

I live in a fairly large house. Since I upgraded to 3.0 on my iphone 3g, in areas that were marginal before, I have no reception from my Dlink 655 router.
Anyone else experiencing this?

Yep, same here. I posted similar thread today. This is totally crap.
Anyone else have a solution or do we have to wait for the next upgrade?

  • MOVED: Lost Wifi adapter after upgrading win8 to win8 pro!

    This topic has been moved to MSI Notebooks & Netbooks.
    https://forum-en.msi.com/index.php?topic=177255.0

    You should be using the "Best for Display" settings for ordinary displays, like the ones you are using.
    Only wacky huge displays, where the pixels are way too small (like retina Displays or 4K displays) use "Scaled" resolutions, and they do multiple unstated tricks: Graphics are displayed at the full native resolution of the display, and text is doubled or scaled so that it is extra-big -- otherwise it would be so tiny you could not read it.
    So ignore "scaled" and use "best for Display".
    And as far as having seventeen different resolution settings, well they figured out that if you paid for the top resolution, that "best for display" is what you almost always wanted, so why bother even showing the others.

  • WIFI Quit after upgrade to firmware 3.1.

    My WIFI quit after upgrading from 2.1.1 to 3.1. It worked twice since the upgrade for a period of an hour or so. I have tried to reset the network, All settings, serveral reinstallation of the firmware. I also Tried to manually enter in my WIFI information, with no success. I tried everything. I can see wifi information when I go into the general settings>About> Wi-Fi Adress 00:1c:b3:48:ce..... My warrenty is no longer valid. Any suggestions???

    I've now posted these changes at two other WiFi threads. Try these Settings changes:
    The Setting changes are:
    Fetch New Data > Push: Off
    Fetch settings are set to Manual & in Advanced all is set to Manual.
    My iPhone also lost WiFi but with the changes above it now connects though it takes a bit longer to find the signal. No longer have Push but WiFi is more important, to me anyway. Another iPhone user had success with the above changes.
    Good luck.

  • 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. .

  • B460 lost WiFi adaptor after Win 7 professional upgrade??

    Got a new B460, WiFi once worked in Win 7 home but after upgrade to Win 7 professional, I can no longer see anything related to WiFi, i.e. when I press Fn+F5, I only see the "bluetooth" icon (hardware button on), and also under Device Manager -> Network adaptors, there's only the Gigabit Ethernet Controller.  Wired connection works fine, just that everything associated with WiFi seems to be lost.  Anyone any clue??  Anyone can help?  Appreciated very much!

    let me ask that, if you don't have any disk, how come did you upgrade your operation system?
    run one key theater to burn recovery disks so you can use.
    or just shut down your computer and press one key recover button to perform clean windows installation.
    you can download drivers from here ( check your d volume for drivers )

  • 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.

  • What can I do to restore good wifi reception after upgrading Snow Leopard

    My situation is similar to what is described by others, but different enough that I thought starting a new thread might help.  I upgraded from Leopard to Snow Leopard (10.6.3) in January.  All was good.  As new upgrades came out I conscientiously updated my software.  Then about 4-6 weeks ago I noticed that I could not get wireless in some areas of my house, further from my router, where I used to able to get fine reception, and where other computers in the house still worked fine.  The other computers are a MacBook Pro (running 10.6.8 but now just updated to Lion) and an iBook G4 (10.4.11).  I also noticed that when I streamed video it was choppy, even if I used an ethernet cable.
    I decided to reinstall from the CD (10.6.3) and that worked; all internet was back to normal.  Then I updated to 10.6.8.  Problem came back immediately. Reinstalled 10.6.3 and all was normal.  Upgraded to 10.6.4 still normal.  Updated to 10.6.5 problem back.  Went back to 10.6.3 and back to normal.
    I have tried repairing permissions and some of the other suggestions I have found here, but nothing works.  The only way to get decent wifi reception throughout my house is to go back to the CD and reinstall.   I see lots of people saying that after upgrading to later versions of Snow Leopard they lose wireless, but no one says they just lose wireless at greater distances from the router.  I am using a Westell 327W ADSL modem router (802.11g) and I am connecting to the internet on Verizon DSL. 
    I would like to upgrade to Lion but I heard that this does not help with the Wifi issues others have reported, so would like to get this sorted out before upgrading.
    Please help.

    The solution given by Tenortim fixed my problem.  Thank you Tenortim
    https://discussions.apple.com/message/12924009#12924009
    It is a little difficult.  You have to be able to use Terminal to do step 3.  Fortunately, my son was able to explain some of the details.  The rest is straightforward. 
    I wish Apple would not include the new firmware without making sure it worked.  I suppose if I upgrade to Lion, which I would like to do, I will have to go through the process again.  For now I will stick with 10.6.8 and the Airport driver from 10.6.4, since that is working great.

    Additional things to try.
    Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

  • 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 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*
    http://docs.info.apple.com/article.html?artnum=107451
    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

  • Lost campass apps after upgraded to ios7

    I lost the compass , stocks apps after upgraded, how can I install it back?
    Ipad2

    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
