Wi-fi and data signal problems after upgrade to ios 8.0.2

Hi all,
I have an iphone 6 and updated to ios 8.0.2 two days ago (skipping the ill-fated ios 8.0.1). However, since the update my wi-fi signal is even worse and keeps dropping out, as does me 3G/4G signal.
Is anyone else having this problem? Should I (can I?) roll back to ios 8?
Thanks!

You are not alone.
As stated by gdgmacguy you may need to do a full reset/restore, but this may be overkill. Before putting your iPhone back to factory defaults, you should try doing a full power down cycle (press and hold the power button, slide the off switch on screen). Wait a few seconds before powering back up. Put your password in to unlock the iPhone and wait to see if your wifi/cellular signal improves. If this does not work, then you need to see if there is something else messing with the handset. The way to do this is to backup all your stuff first and then do a full factory reset. DO NOT RESTORE your iPhone yet. Let it start up as a new handset. If your wifi/cellular signal does not improve, then there is likely to be a hardware issue and you should take the handset back to your point of purchase. If your signal does improve without any apps etc, then it could well be that you have some apps using background services. Turn off background services and switch off cellular data and see if this helps with the wifi stuff. If so, then you need to go through the list of apps trying out which combination works.
iOS 8 is - in this shark's opinion - a bit of a bugfest and still has a number of issues for Apple and Developers alike. I expect to see 8.0.3 and 8.0.4 or maybe even 8.1 before too long.
Hope this helps.

No signal problem after upgrading to iOS 5

Hi, I upgraded my iphone to ios 5 but now these two weeks every so often at least twice a day my phone drops all signal bars and says no service, or has full signals but no 'Rogers' sign, so I cannot make phone call, and when people call me they said there is no answer but there is nothing shown on my phone. Also, when that happened it freezes in between when sliding between screens. After i turned off it and restart it then it goes well again. however, it often go no service during night. when that happened, all the applications dont work either, most importantly the alarm, because of this i missed one very important quiz. I have restored it once but it just occasionally loses service for no reason. some times i even get an activation required message after i turn it off. I really tired of missing my morning class...However, I just bought it from apple store online on April 28 this year, soI was wondering whether I can go to apple store to change another one since i still have one year warranty??

If you have done all the troubleshooting that the apple support site has told you to do i would go ahead and call apple and see if they can support you further.

I am facing wifi and mobile 2G signal issue after upgrading to IOS 6 from IOS 5 in IPhone 3GS. Please help, restoring setting even didn't helped.

I am facing wifi and mobile 2G signal issue after upgrading to IOS 6 from IOS 5 in IPhone 3GS. The mobile carrier signal as well as WIFI suddenly drops zero and are then restored automatically. Sometimes i cannot conenct to WIFI even standing infront of WIFI router. Please help, restoring setting even didn't helped.

Update: my phone's connecting to the WiFi again. I don't know what did the trick. I did nothing since reinstalling the software. It hadn't worked then, it is now. I tried connecting to my dad's phone's hotspot( he uses a Moto G), and it worked. I then tried connecting to the WiFi at a friend's house, and when I came back home, my phone was able to connect to my WiFi! Is it of any significance that my friend's router doesn't require a password? My issue has been resolved( for now; I hope I'm not counting my chickens before they've hatched). For anyone facing a similar issue, I suggest you try everything I did:
1. Turn your router off for a minimum of 30 seconds, turn it back on and try connecting.
2. Click on the WiFi network you are connected to, scroll to the bottom, tap "Renew Lease".
3. Do a soft and hard reset.
4. Reset network settings.
5. Back your data up, erase all content from settings menu, restore from backup.
6. Reinstall your software( put it in recovery mode).
I am not sure which of the above worked for me. Make sure you try everything. If none of the above works, take it to a genius bar or an authorised service provider. Good luck! :)

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

Smb protocol problem after upgrading to IOS 8

Hi,
I use SMB protocol to connect to Windows share folders in our company.
Using IOS 7 on the iPad was working great until i upgrade one iPad to IOS 8.
I can't connect using SMB protocol on the iPad with IOS 8. With an iPad with IOS 7 still works great.
The settings are the same. I tested Goodreader v3 and v4 and FileExplorer program on the iPad with IOS 8 and on the iPad with IOS 7.
The problem is only on the iPad with IOS 8. It does not matter which program I use. All are not working.
On the iPad with IOS 7 all the programs works just fine.
It seems that after upgrading to IOS 8, I have problem connecting to the share folders in Goodreader v3, v4 and in FileExplorer.
It seems the problem is not on the settings of the server, account etc, also not program related but with the IOS 8.
Does someone have this problem or now how to fix this?

Hi all,
I have run some more test and the problem is not with the SMB protocol but to connect to a DFS server.
One share name like company.local and behind this we have some servers.
The problem is with the DFS name (routing) When I connect directly to one server share location, it works fine.

Anyone else having volume icon on ipod touch 4gen just popping up and not working properly after upgrading to ios 6.1?

Hi, has anyone experienced issues with there volume control icon randomly popping up after upgrading to ios 6.1 from 6.0 .
I have a 4th gen ipod touch which until upgrading to 6.1 from 6.0 was working perfectly.
Minutes after the upgrade I noticed the volume icon just popping up for no reason. I can turn the volume up now, but not down and it randomly appears on screen without anyone touching it. Weird! Can someone shed some light on this issue,I have reset and reloaded to factory several times now to no avail.
thanks!

I am having this same issue on my iPhone 4. The most recent update to iOS 6.1 didn't fix it either. Has anyone found a fix for this problem? It doesn't happen often, maybe every third day or so but requires power off, power on to bring the sound back.

Email problem after upgrading to ios 8.1.3

After upgrading to ios 8.1.3 my wife and I are having problems with our separate iPods downloading email messages from our Hotmail accounts. Synchronisation can be slow, sometimes doesn't happen, and at other times the header information downloads but a message says the content could not be downloaded from the server. Swiping down to do an email refresh doesn't solve it. Closing down the email app and switching the iPod off and on does cause the message to download properly. Of course it could be a MSN/Hotmail problem, but it seems suspicious it has coincided with the 8.1.3 upgrade. As a cold reboot solves the problem, I think it is a problem with ios 8.1.3.

I have this exact problem with gmail and have been unable to solve it. I checked my account, smtp settings, everything is as it should be. I deleted my account (twice!), and then added it back in. No help.
The problem however didn't appear right away for me on my ipad (3e gen). It occurred rather spontaneously in the last week of february.
Strangely, it recognizes my account, and I can send e-mails with it. So the problems seems to be on the receiving side. It recognizes the structure of my gmail, but all the folders are empty. On my iphone 5 I do not have this problem.
My workaround for now: download the google gmail app and use that to check my mail. Sending still works with the ipad mail app. But it is frustrating not being able to use this to receive mail.

Problems after upgrading to iOS 5.0...

Hi,
maybe it's been said and maybe it's a matter of the iPad 1, but after upgrading to ios 5.0 all my apps started to reset when used. Is there something I can do to avoid this? I tried resetting the iPad and nothing....
Kind Regards

If the apps that are crashing are third party apps - not the Apple installed apps - try downloading another app - any free app will do. That resets something in your iTunes account and it should allow those third party apps to work again.
You said that you reset the iPad - but if you didn't reset this way - try it - Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
You can also try quitting all apps and see how the iPad behaves once you start using apps again. Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
You could also try restoring the iPad if nothing else works.
A number of us are experiencing issues with this update. Apple announced that an update (iOS 5.01) is coming soon and it has been released in Beta to developers. Hopefully, the general public will be getting it soon and it will help resolve some of these "buggy" things that some of us are experiencing.

Problems after upgrading to ios 6.1.2

After upgrading to ios 6.1.2 my iphone4 no longer recognises the docking station - anyone else having this problem, how to i fix it?

I have the exact same problem following the software update. My phone doesn't work with my handy clock dock, nor will it work with my FM plug-in for my (old, pre USB jack) car. Is this some ploy by Apple to get us to buy only Apple-brand accessories?

Date format problem after Upgrade in BI

Hi Gurus,
We have just completed our upgrade of BI System to EHP1.
My users are facing a very typical problem.
Before the upgarde they could enter date while running a report in the following format:
20100215 in date variable (No slashes or dotd.)
After the upgrade they are forced to enter 2010/02/15.
If they don't enter slashes system does not accept that.
Any idea if we can rectify that somehow.
Regards

Checked in there alreday. Problem does not arise from there it seems.
I hope I am clear enough abt the problem.
Users are forced to type "/" between year month and day. Prior to Upgrade they did not need to type "/" between year month and day.

Disk Utility and repair permissions problem after upgrade 10.5.1

*Problem with Disk Utility* - +repair permissions don't work anymore+
After upgrading to OS X 10.5.1 tried to correct permissions with Disk utility. But I'm not able to repair permissions, because I get this message every time "fault: The underlying task reported a fault at concluding." and permissions repair stops. Has anyone else had this problem and does anyone have any idea how to get this working again?

Will try installing OS X 10.5.1 again from the downkoad that you recommended. Won't be able to do this untill after the New Year but I'll let you know if this helped. I had another problem after he 10.5.1 upgrade and that was that the Security update 2007-009 also refused to install. Could this be related too the problems with Disk utility and the permissions problems.

Signal issues after upgrading to ios 6.1.2

ever since i've upgraded to ios 6.1.2 have had problems with my signals, hv never seen all bars; 2 at most. hv drop calls all the time. it;s irritating . tried evry thing like network resets, turning off/on 3g and lots of stuff suggested in other threads bt in vain . happened once before in one of the ios 5.something series bt ws fixed on the next ios upgrade. apple needs 2 fix this soon and launch the next update .once fixed i dnt think i'l eaisly try experimenting with ios updates.

Exactly the same as me. Updated now can not get FaceTime to work. Just hangs on the connecting page then loses connection after several seconds.
Friends calling me does the same thing.
It is not our router, I can download and upload data quickly without any problem.
Who quality controls IPads? Seems lots of mike and connection problems with Talktime at the moment. Apple must be embarrassed.

3G Signal Loss after upgrading to ios 4.0.1 ?

Hello Everyone,
I don't think that I am the only one with a 3GS that is having this problem. I have the iphone 3GS, I was very excited to upgrade to ios 4.0. Once the upgrade was complete everything was just fine. Then came along ios 4.0.1, I figured why not. Isn't that what you are supposed to do to keep you phone up to date. Well, ever since I upgraded to ios 4.0.1 I have lost my 3G signal. My wife's phone is the exact same model, purchased at the exact same time. She is still running ios 4.0 and not having any problems. I spoke with Apple Care today and they said that ios 4.0.1 was in no way going to affect the 3G signal strength. Now, if I take my phone and my wife's phone and hold them side by side. She will have full signal and I might have one bar. Then when I go to safari and try to load a web page. Her phone,(with 5 bars) will download twice as fast as mine.
Is there any way for me to go back to ios 4.0?
Thanks Apple for fixing all of the iphone4 problems and creating one on the 3GS and then not acknowledging it.
Any help would be greatly appreciated.
Thanks,
Demi

THERE IS A GROWING AND VERY STRONG DISTASTE AT THE LACK OF SUPPORT AND INTERVENTION BY APPLE IN HELPING THE MANY THOUSANDS OF PAYING CUSTOMERS WHO HAVE PURCHASED IPHONES AND FIND THEY ARE NOT FIT FOR PURPOSE.
I AM HAPPY TO INVOLVE THE BBC IN THE UK AND OTHER MEDIA SOURCES TO HAVE APPLE SIT UP AND TAKE NOTICE OF THE NUMBER OF DISSATISFIED CUSTOMERS WHO HAVE PAID LARGE SUMS OF HARD EARNED MONEY FOR A PHONE CAPABILITY THAT IS DISGRACEFULLY BAD. LIKE MANY OTHERS THE IPHONE CAN BE PLACED ALONGSIDE OTHER COMPETITOR'S DEVICES WHO HAVE CONTINUALLY GOOD AND CONSTANT SIGNAL STRENGTH WHILST THE IPHONE SHOWS NONE.
ON A PERSONAL BASIS THIS PHONE HAS CAUSED ME TO LOSE OUT ON A NUMBER OF SIGNIFICANT PHONE CALLS, SOME INVOLVING THE DEMISE OF A RELATIVE - MATTERS THAT CAN NEVER BE REPLACED. AND YET THE ISSUES REMAIN.
PLEASE, ANYONE, FEEL FREE TO EMAIL ME ON [email protected] WITH CONSTRUCTIVE COMMENTS ABOUT THE POOR QUALITY OF THE PRODUCT (IPHONE 4 OR 3GS) AND THE EXTENT TO WHICH THIS MATTER HAS BEEN OCCURRING AND THE IMPACT IT HAS HAD ON YOU EITHER DOMESTICALLY OR IN BUSINESS. I AM LEAD TO BELIEVE THAT THE FAULT DOES NOT LIE WITH THE NETWORK BEARERS, BUT IN THE APPLE IPHONE DEVICES THEMSELVES
I CANNOT PROMISE TO DO ANYTHING OTHER THAN COLLATE THE EVIDENCE THAT IS COMING IN FROM SO MANY SOURCES AND PROVIDE IT TO THE MEDIA GIANTS THAT MAY CAUSE APPLE TO DO SOMETHING. FRANKLY I THINK ALL THE DEVICES SHOULD BE REPLACED WITH ONES THAT ARE FIT FOR PURPOSE OR REFUNDS GIVEN. PLEASE GIVE ME YOUR VIEW ON THIS IF WRITING TO ME. THANKS,
THANK YOU FOR READING THUS FAR. JDMCB

Keyboard problems after upgrade to iOS 8.02

has anyone else had problems with the keyboard obscuring the screen since upgrading to iOS 8.02?. I cant see what I'm typing.

Hey Dizzy blue,
Thanks for the question. I understand that you are experiencing issues with your iPad after updating to iOS 8.0.2. If you have not yet already done so, let’s try restarting or resetting your device:
If the issue persists after a restart, let’s see if we can isolate further by backing up and restoring your device as new:
iOS: How to back up your data and set up your device as a new device
http://support.apple.com/kb/HT4137
After erasing and setting up as a new device, your device is now in a factory configuration. Test to determine if erasing and setting up as a new device resolved the issue. Content on the device may have caused unexpected behavior.
If the issue is still present, you may want to contact Apple Support.
Thanks,
Matt M.

Ipad 2 and Iphone 4 hybernates after upgrade to IOS 6

Hi , After upgrading my iphone 4 and Ipad 2 to IOS 6 , both devices go in "hibernate" mode after being idle for a while. The only way to open them is by hard rebooting. Have you expirienced similar problems ? Is there any solution to fix it ? BR Robert

Andrew is partially right. With apps that are still running, they are running regardless of being suspended or not. A restore should be her last option. as she will lose anything added since her last back up. And there should be NO reduction in speed as the update was made compatible with all phones included in the update.
I recommend the following.
1st, delete all apps on the phone that are not being used. They take memory and speed since almost all apps run in the background checking for notifications.
2nd, go disable all notifications you don't need. This will help with speed AND battery life.
3rd, location services.... Go adjust this... if you don't NEED it on, turn it off. It will reduce usage on the phone, and again save ALOT of battery life.
4th, organize apps into folders. this will ruduce "pages" on the phone, and increase speed.
5th, clear browsing history.
6th, delete emails, texts, contacts that are not needed. ESPECIALLY Spam folders!! some of us never clear spam, and there could be a large amount.
7th, Do a hard restart. While the phone is powered on, hold the home button and power button down at the same time. Keep holding while the phone suts down and keep them held down until the Apple logo reappears.
If this does not help, then she needs to take a record of all contacts shes added since her last back-up, email all photos taken since her last back up, so she can save them back to the phone,(DO NOT rely on photostream, because once the restore is done, those photos will be taken from the stream.) She will need to do the restore off her computer and the update through iTunes.
