Wifi weird problem after upgrade on 4.1 (Iphone 3GS )

I have a strange wifi behaviour on my 3GS that appear just after the 4.1 upgrade
if i let the wifi connect overnight, it's not working anymore after some time
I see the networks around, i can connect, but no data goes thru
If i just reboot ( or respring sometime ) wifi work again ...
Is this because 4.1 is so buggy, or something else ?
dont want to loose hours to do a DFU restore for nothing
PS : As we pay so much for their stuff, if Apple could just work a little bit on the QUALITY of the code for iOS ? thx a lot

The IT group re-downloaded the compressor 4.1.1 app and it worked the second time around. Files sizes were exactly the same so I don't know what was up with the first attempt. Anyway, fixed!

Z30 wifi range problem after upgrade to 10.3.1.1565

After upgrading on Z30 the OS from 10.2 to 10.3.1 I experience serious Wifi range problems. There is a room in our house where I had excellent wifi connection with 10.2 and now the Z30 does not find the router. Even the router SSID! If I go closer to the router, it connects (5-6 meters from the room where I tested). It is a quite new router, a Linksys EA6200 with the latest firmware. I rebooted the router. No result. I restarted Blackberry (switch on/off), no result. I deleted all wifi saved connection on phone and tried to reconnect. No result. I tried to make a soft reset (vol up/down buttons), no results. Dont understand, I made Over the Air (on wifi) OS update yesterday in the same room, same place. Now I dont see any router there altough the Android phone and the notebook gives 4 bar wifi there. Before OS Upgrade I made a full backup (everything) in the Blackberry Link, tried to restore to the earlier OS version, but the restore uploaded to the new OS the personal data and not the earlier OS System. How I could solve the Wifi problem or roll back to the earlier official version? I dont see possibility on phone. It's crazy to have a quite good business phone which is now unuseable for its original functions without normal wifi connectivity... I understand to advise hacking or restarting router, etc... but how about if I go to abroad? I cannot restart the router there... I need stable wifi or a stable operating system...

I have seen numerous posts on other forums about the degraded wifi performance on devices running 10.3.1.xxxx.
I definitely noticed a dropoff in signal strength when I went up to 10.3.1. I remedied it by putting in a better router, but I don't believe one should have to do that in order to maintain was was acceptable performance under a previous OS. 10.3.1 is supposed to be an upgrade after all.
I also notice a difference between Z10(STL100-1) and Z30(STA100-6) on 5GHz wifi : Z10 finds and connects with no problem, but Z30 does not find the network at all, even when right next to the router. I subsequently discovered that the router autoselects channel 149 on 5GHz, which the Z10 is happy with. For the Z30, I tried all other available 5GHz channels on the router in turn, and eventually found that Z30 will find and connect if the router is manually set to channel 48 only. A bit restrictive for a high-end device.
It has been postulated that the claimed improved battery life on 10.3.1 comes at the expense of compromised wifi performance. Could this be the case?
Hoping this issue soon finds itself in the "under investigation" box at BB.

Wifi connection problems after upgrading to 4.3.5

Hello everybody,
I have the same problem on iPhone 4 and iPad 2 after upgrading to 4.3.5 (8L1): once you are connected to a wi-fi network and after you leave the device unused for a while (so that it goes to sleep) the wi-fi connection is lost and the only way to get it again is to switch wi-fi off and on. After that everything works until the next sleep.
Is anybody experiencing the same problem?
Thanks
Diciotto

I have similar problem with my iPad but not with iPhone 4. Have you figure out why and how?
Thanks,
Grace

Problem after upgrading to IOS 7 (iphone 5).

Many functions lost after upgrading to OS5 on iPhone 3GS

Recently, I've upgraded my OS for my iPhone 3GS to OS5 version, and many of the useful, or rather basic function on the default iphone apps are gone.
For example, firstly, the symbol in the calendar app is missing, and I could no longer add an event or activities when I open the calendar overview application. Although, there is a new app called "Reminders" which came with the new OS5 version, I could only input one alert reminder, which in the past I could create two alerts to alert me twice (different day/time count-down) for the coming event activity.
Second, the "Contacts" application. Likewise, same issue with that of the calendar app, the symbol too was missing and no longer available to add new contacts. I have to open up the "Phone" app, and had go onto the recent calls tab to create a new contact. Another added bug for the "Contact" application, is that when I select on any of my contact in the phonebook, the "Edit" is no longer available too. It used to have it there...now I can't edit anything or add any further information of a particular contact, not to mention delete/ remove it too.
Third, I heard the new OS5 is able to allow 3GS iPhones to function/ act as a router for internet tethering when personal hotspot is turned on. But it seemed like, it only works on iPhone 4 and above.
Fourth, I used to be able to set to manual synch whenever I plug my phone to my comp, but I can no longer do so as the iTunes does not automatically open when I plug my iPhone into my comp. I had to tick the "open iTunes when iPhone is connected", but it automatically synch my phone and backup the data when I wanted to manually choose to do it like before selecting through the "File" in the top menu.
So far, these are the major basic problems I've encountered. Would Apple please dedug and resolve these problem ASAP??? I am getting pretty impatient after have feedback to Apple since 3 weeks ago after the upgrade, yet no new OS updates is been available to resolve the bugs..

The question I have is; "WHY does this work?"
How about it Apple "Gurus"
Well, it would seem that the issue here is that iOS4 is not properly reading the backup that was created before the update. Or the backup is not being created in a properly formatted manner. There are just too many cases of a post upgrade issue being solved by restoring as a new phone for it not to be bad data.
Pain in the hiney, I know. And this is nothing new. All the way back through the iPhone's iPod roots, there has alway been a point in the troubleshooting tree that comes down to "restore the iPod". Just a more awkward thing now that the iPod has evolved into a phone and is trying to keep any number of settings straight. Not to mention no one wants to take their phone down unless there is no other option.

Battery life gone after "upgrading" to 4.3 (iPhone 3GS)

I've lost all battery life after upgrading last night to ios 4.3! I barely get 5-6 hours, whereas I always got a full day (probably two if i let it run down) before the upgrade. I can't believe this is a coincidence. How do I go back to 4.2? Or is there a cure for this?

OK, problem solved, with the help of Apple Support.
They suggested that I re-install the upgrade using Restore on iTunes. So I backed-up the iPhone, did a Restore to factory settings, and then restored all the apps, music etc from the back-up. The phone was fully charged 8 hours ago now, and has gone down to 80% with some occasional use .... this is typical for my 3GS. So: "Restore to Factory Settings" worked. Don't ask me why!

Problems after installing new version o iphone 3gs

I installed this evening the new version of my iphone 3gs and since then I cannot use my iphone nor reinitialise it beause it asks me to connect to itunes.When i connect it to the computer it say there is no pilot and doesnt manage to install a new pilot I telecharged the last version of itunes and reinstallated it, try again to reinstall the pilot but impossible to connect and I can't use my iphone
Help me please

A warm welcome Sabina!
i wonder if the issue is the new battery (can that cause a slow down
and malfunction of this sort).
Not too likely at all.
or if my HD is the problem.
Very likely, I would expect all Laptop HDs 4 or more years old to be failing by now.
i just read somewhere that whenever we do the updates we're supposed to do the permissions and i never knew to do that -- so i haven't ever done it. could that be the problem.
That and Verifying or Repairing the HD are sort of like looking both ways before you cross the street, neither may be necessary to cross the street, but it certainly can prevent problems during the crossing!
should i do a clean install of the system software and start from scratch.
I really think the Internal HD is on it's way out, but if you have a good/complete backup, actually a bootable clone on an external Firewire Drive is preferable... Best way to get an exact bootable copy of your old drive to the new one is with Carbon Copy Cloner...
http://www.bombich.com/software/ccc.html
thoughts would be appreciated. i don't have the money to take it anywhere to be fixed or to buy new -- so any help is greatly appreciated.
Without Money to replace the HD, you may be stuck booting off an external HD

E51 Wifi access problems after upgrade to 400.34.0...

Hi,
So after I recently upgraded my E51 to firmware version 400.34.0111 I can no longer save access points successfully. Even after successfully registering the access point, entering the auth info and using it, it never seems to save it. I've even gone into tools -> settings -> connection -> access points and manually entered the information there and yet it still doesn't save it.
This is _extremely_ annoying as I tend to roam alot and use many differnt access points. It seems the only access points which don't constantly prompt me for a password are the ones that were registered prior to the upgrade.
Any suggestions?

Reset the E51. Dial *#7370# 12345 reformat, you'll lose all data. Make a backup first and restore without the settings.

Problems after upgrade: Leopard to Leopard no longer works

My sister upgraded to Leopard on her iMac(c2d) to Leopard yesterday. Earlier in the day we were able to do video chats with a number of people(her machine Tiger to Fathers machine Leopard). However, since upgrading, we've experienced weird behavior for video chats. Basically in her window she won't see her image(the small one), and I don't see her at all. We've tested this out with a number of other iChat accounts and get the same results. Btw, all machines that are chatting with her are using Leopard. Also, all other forms/capabilities work: screen sharing, sharing of pictures, audio chats.
Anyone out there have similar problems after upgrading from Tiger to Leopard? I have done the usual adjustments of bandwidth and QT settings, as well as restarts. What else should I try?
tia,
n

I finally resolved this problem: I think the issues/steps would be helpful for anyone who experiences iSight off or not working problems after upgrading to Leopard(then to 10.5.1) on a intel 20" iMac :
Problem:
-If you have an internal iSight on an iMac and your camera works fine in Tiger
-If you upgrade to Leopard
-If Chat camera doesn't show your image (iSight off) even though the green light is on
-You can see the other persons video on iChat
-Your friends can here you and you can share screens, files, etc.....everything but have them see you
These are the initial steps I took:
- Deleted the pLists(or stored preferences for the Application) described at the top of this thread
- Was told it might be slow internet connection so did various things: disconnected other computers, changed wireless to "G" only
- Specifically Opened of ports spec'd for Leopard on router (even though I hadn't needed to do this under Tiger)
- Tried chats with various people on various fast/slow networks
- Restarted all aspects of the network: router, wireless access point, computer
- Checked to see if the iSight was shown in 'System Profiler'. It was found in 'About This Mac->More Info->System Profiler->USB'
- Clicked Video icon in iChat Buddies window(to the right of your name) and coudn't see my image
- Opened 'PhotoBooth' and coudn't see my image(black screen)
- Opened iMovie and couldn't capture video via the iSight(black screen)
- Opened iChat->Preferences->Video and couldn't see my image
- Validated that 'Camera is Enabled' in iChat->Video->Camera is Enabled
If you are experiencing a similar problem with you built-in iSight, I would probably focus on the last 5 things that I did. What they showed me was that the iSight was just not capturing video even though it was capturing sound in 3 different applications.
The solution to iSight Off or iSight Not Responding or No Video is......reset your computer! I had thought my sister performed this but it turns out she hadn't. Here's the link to this procedure:
http://docs.info.apple.com/article.html?artnum=303446
Very easy to do though: Power off computer and unplug all cables, including power cable for at least 15 seconds. Plug everything back in and power up the computer and retry clicking on the 'Video' icon next to your login name. If you see yourself then...problem is solved.
While I eventually found posts in several other forums, it took me the better part of a week. To try this simple step. I wish I had done so straight away. Oy. I guess I learned a lot about ports, speed etc.
I hope this helps.

Problems after upgrading to iTunes version 6

Hello,
I've been going through the threads a lot since I have had problems after upgrading to iTunes v. 6. It looks like a lot of people have had the same issues, and I have tried some things that were recommended. After I upgraded, iTunes would not open. I tried:
1. deleting sidb file
2. doing the msconfig thing suggested in discussion boards
3. going into safe mode and deleting 4 and 6 letter weird files in DOS - I found 3 that I deleted
iTunes worked after this -- then I bought a song and it said my computer was not authorized, after I authorized computer (that never happened before), iTunes worked for about 15 more minutes and then closed down abruptly. I haven't been able to open it since.
I also downloaded Spybot search & destroy and that did not find anything. I am using McAfee, and have scanned for viruses with McAfee and AdAware.
Now, when I restart my computer, a bunch of windows pop up with Chinese/Japanese looking characters and say that device (I think) was not found. I seem to be able to use everything except iTunes and Quicktime. When I open the Task Manager, iPodService.exe and iTunesHelper.exe and qttask.exe are there, but when I click on Quicktime or iTunes the file flashes in Task Manager and then disappears.
I'm not sure where to go from here.
Any help would be apppreciated -- I'd like to be able to open iTunes!

Hello,
I used Nickroo's post:
I was able to get iTunes launched (with the help of Tech Support) in a very unsafe environment. I owe it to those who may need this after me. It will get you going, but you will be extremely vulnerable to internet virus assaults. Please do not use this approach, until you have exhausted every other available solution for your issue in the KB.
There are three Steps 1) Uninstall 2) Disble and 3) Reinstall.
UNISTALL Uninstall iTunes using Windows utility Add Remove Program available in Control Panel.
DISABLE Disable all third party System Services and Startup Items using using MSCONFIG utility as described in Service Document http://docs.info.apple.com/article.html?artnum=302538
RE-INSTALL Re-install iTunes6 + QT7. Launch it under the Selective Startup Option.
It worked ! You realize among other things at this point you have your Antivirus and Firewall disabled. When I started my computer in the Normal Startup Option, iTunes fails to work again. So I have ahead of me the long and ardous task of ruling out the service that is causing conflict with iTunes6. Then work with the software vendor to arrive at a solution.
This seems to have worked so far- I haven't started to go through ruling out what made iTunes not work; I also haven't tried to connect my iPod or burn a CD, so we'll see.

I think you had better to flash back to beta 4.39 bios, here : https://forum-en.msi.com/index.php?topic=164135.msg1214789#msg1214789
And use and install on USB key MSI Forum HQ USB flashing tool from here : https://forum-en.msi.com/index.php?topic=108079.msg800577#msg800577
Flash using method 1.
And tell us if that works.
thank you for reply that fast i will try asap and tell here.
Btw, have you ever face a problem as i wrote above?

Permission problems after upgrade to 10.5 on early Power PC G5 Tower

Permissions problems after upgrading to 10.5 on a client power PC (early) G5 tower.
Problems include folders that are created on XServe via this client do not allow any one else including this client to access. All other clients running 10.5, which happen to be newer Intel machines do not have this problem. Repairing permissions, updating to 10.5.1, try to manually correct permissions have all failed to repair the situation. All clients log onto the XServe with the same user/password. This client has since been downgraded back to 10.4.9 and has no issues.
The Xserve runs 10.3.9, any help would be greatly appreciated.
We have read through the forums regarding permission problems after upgrading and even tried some tips found here.

You really should check things out first before speaking.
Here are the requirements for 10.5;
Mac OS X v10.5 Leopard requires:
A Mac computer with an Intel, PowerPC G5, or Power PC G4 (867 MHz or faster) processor
512 MB memory or more
A DVD drive for installation
9 GB of available disk space or more
Some features require a compatible Internet service provider, fees may apply.
Some features require Apple's MobileMe service; fees apply.
