IOS 6 iPhone 4S weak carrier signal

I upgraded my iPhone 4S yesterday to iOS 6.
From my office I was getting a consistant 3-4 bars and EDGE (T-Mobile US) signal before the upgrade, but now the signal is coming and going, and going "No Service" very often.
Any clues?
Is there a need for iOS updates?
Thanks

Similar here. I had 76% as of when I finished the download 3 hours and 40 minutes ago, and now my battery is at 40%.
In the intervening time, I had one 3-minute phone call, 2 emails (less than 5 minutes on email), 2 text messages, and phone asleep with screen off the rest of the time. I turned off all location services except Find My iPhone, and set Spotlight Search to index only email, contacts, and nothing else.
The last 2 steps worked like magic for me when upgrading to iOS 5, but have not helped much if at all with iOS 6. I just did a hard reset, and will report back in several hours regarding the apparent effect of the reset.

Hi Samantha,
Are you aware that if you restore your ipad that you will lose all data from your ipad and very difficult to get it back unless you had previously made a back-up of your data on itunes or in the cloud. and that would be on the computer you set those up on. (There are some independent apps out there that might help restore data but I don't have any experience with them...)
Also, I think if you restore on another computer you're supposed to have administrator rights and have the latest itunes update. And I think if you sync (if restoring is considered syncing with another computer, you'll be locked out of your computer or a new one.)
I don't know if there is a way for you to safely eject your ipad from your mom's laptop and find another way, but please read this
http://support.apple.com/kb/ts1275
Also, I suggest you start a new post and title it something like First, stuck on update and now on Restore on another computer. Please HELP! And then tell the story of your problem that you originally included and your follow-up efforts to restore given a suggestion on previous post (though I think you SHOULD AVOID RSTORE if you can.) And refer them to your original post
https://discussions.apple.com/message/22050045?ac_cid=tw123456#22050045
Hope this helps and if you can get back to your ios before the upgrade, stay with it. I hope it all works out for you.
FYI - If it's a new or refurb bought within the past year you might be able to have it replaced by Apple.

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.

My iPhone 3GS lost the signal operator completely after upgrading to iOS version 6.1.2, someone with the same problem? Just think when I enable the 3G, soon followed falls again.
I have already put another chip carrier and the same problem happens, my phone is factory unlocked.

Had same problem with iphone5 6.1.2 update. First tried reset network settings and didn work... Support recommend me a restore and ended up in recovery loop with iTunes error (-1)
Been at my carrier store (Optimus Portugal)... and iPhone sent to warranty. After 2 macbooks, 1 imac, 2 appletvs, 2 iphones, 1 ipod... I find disappointment with apple reliability....
At least the support guys at Optimus Portugal were very helpful and friendly, but I'll be 15 days without iPhone...

IPhone 4S has no signal bars but shows the network carriers name and the 3G icon but just doesn't have no siganl bars

Hi my iPhone 4S has no signal bars but shows the network carriers name and the 3G icon but just doesn't have no siganl bars but it was working fine till today then all of a sudden lost signal what do i do any help much appreciated

I've been experiencing with the same problem lately. Have you tried getting a new sim card?
With the new sim it seems to work well for a few days and then it goes back to the same problem. The warranty on my phone just ended about a month ago, and I've never dropped it and no water damage either. When I do a erase all and reset, it seems to work for a few days again and comes back to the same issue. I've deleted all my apps and been using the phone just as a phone and txting device. New IOS update doesn't seem to change this issue either. I've been getting by with doing a network reset and turning it off and on a few times a day.
Anyone have any solution? Much appreciated!

Iphone 3GS very weak wifi signal since 4.3.3 update

Ever since i update to 4.3.3 (which I'm regretting now) my iphone will not connect to my wifi router unless I'm less than 3 feet from it.
My wife has a 1st gen IPod touch (which hasn't been updated) can pick up the wifi and connect to the wed with it upto 30 feet from the router, as my iphone used to.
Is this a 3GS issue as i've read some other posts about a similar problem. I'm not willing to accept this as a hardware problem as the minute before the updating to 4.3.3 my wifi signal strength was prefect, the minute after the update was complete the signal strength was and still is worse than sh*$e.
I have done all the power down resets as suggested on other posts, but it doesn't work.
Is there anybody out there that can tell me how to (if possible) to revert back to 4.3.2?????????????????????????????????????
RLB

I don't have the answer to this issue but I'm experiencing the exact same problem.
Since 4.3.3 my wifi signal strength is close to nothing. When I'm 3 feet away from any router, at home or at work, I have 3 bars not even full reception. As soon as I walk a few yards away from the router, I lose the connection completely.
I've tried everything to fix this. Reset network settings, turning off Bluetooth, disabling location services, full restore, reconfiguring routers, etc. but nothing works. I'm now using the iOS 5 Beta 3 and still no improvement to this issue.
In this thread there seems to be some recognition from Apple that this is a known problem and indeed a software bug. Hard to know if it's true though:
https://discussions.apple.com/thread/2815831
The same weak wifi signal seem to happen to iPad users too: https://discussions.apple.com/thread/2387493 This thread dates back over a year, so it looks as if this problem is common but without fix.

I have a "case" open with Apple for poor carrier signal strength after upgrading my iP5 to iOS7.
Please make sure you open a case with Apple.

Iphone 3gs extreme weak wifi signal with wrt160N - suggestions?

Linksys wrt160N v3.0.00 build 010 Jan 30, 2009
iphone 3gs firmware v3.1.2
Set up network to include a few laptops with N cards, a PS3 – all ok
When it comes out of sleep mode it connects at full signal strength , then within 15 seconds drops to just the one dot
Under a dLink G router, full signal strength right up to 30 feet outside of the house
Here in condo just purchased the Linksys and standing right next to it i get a practically non existant wifi signal
Go back to parents house with g router , works perfectly.
I thought the N router is set up to be backward compatible and if need be broadcast in G mode for G devices
Is there anything I should be aware of in the settings.
I followed the basic setup - no manual fiddeling with any of the settings.

1. You can check all the settings through the web interface at http://192.168.1.1/
2. As long as your iPhone maintains a connection and does not really slow down it does not matter how many bars the iPhone shows. I think the iPhone has problems calculating the correct signal strength on 802.11n routers. I have seen something similar on a dlink router. My iPhone jumped from 5 to 1 and back. Most of the time it was at 1 bar. Yet, I had perfect connections and normal internet speed. Thus, check internet functions on your iPhone. Unless you loose connections or they get extremely slow I would simply ignore it.
Problem being is that I'm not sure where to check via the web interface as to what mode it's on right out of the box.
The only way, recalling from last night's attempts, is if I go in and select the manual settings option rather than the wifi protected button, which would then allow me to enter manual settings.
Only there, would I know what it would be set at because I would obviously have to set it. I'd rather not go into changing manual settings unless absolutely necessary at this point.
As for the iphone not displaying the signal strength correctly - I'd have to say it is, given the following download speed test results: 27, 95 , 28, 149 kbps (not the most spectacular) compared to say 9388 kbps when the iPhone initially comes out of sleep and connects to the network. The signal drops to the one dot within about 10-15 seconds approximately.
With the old dLink G router, the signal strength registered full and download speed tests supported that, same as outlined above with the weak signal and corresponding d/l results.

IPhone 5 weak signal become iPhone being tempered with no serial number. Horrified!

I faced weak wifi signal problem with my new iPhone 5. Hence i went to the service provider, Singtel to check the problem and was told after they open up my iPhone that there was no serial no. inside the phone. As such, they were not able to help me cos mine was a tempered product.
But,
1. I received the new iphone from Singtel by renewing my contract. How would I know the phone was tempered.
2. I was not there when the phone was opened, as they took the phone into their backend room. How would I know if Singtel tempered it themselves?
The chance is low but who knows. Afterall, this is the same logic they gave me, since they say they don't hold responsibility for tempered phone as they won't be sure if I have tempered the phone even though the chance is low. Obviously, I would be real dumb to not expect they would open the device to check if I really wanted to cheat.. And for a corporate phone, it has to be a really desperate person to want to resort this.
3. If I had not observed the wifi signal weakness, I won't have even bothered to go to the service centre. In fact I was still holding on to my iPhone 4 and resisted to switch as all my data was there. I switched only when my singtel cut my iPhone 4 service and i had to activate my iPhone 5.
4. So the thing is, I would be cheated with a tempered product had I not have my weak wifi signal problem. I wonder how many other consumers are cheated.
5. Anyway, I though each device comes with an unique serial number. My iPhone 5 serial was registered in my phone when I activated it. Is it not proof that this is a genuine phone?
I am supposed to be a short changed customer to have to waste my time visiting Singtel for a phone problem and then being told that my phone has been tempered with and hence my warranty for the new phone is void.
I would really appreciate it greatly if someone could share with me how I should best resolve this. Thanks so much!
Best regards,

Thanks for your advice and taking the time to reply. :)
Actually, I thought so too that the serial number in my setting would identify my iPhone as a valid apple iPhone. However, the service provider who supply the phone with the plan do not recognise that. They told me that under their policy, if a phone has been tampered with, in this case no serial number inside the iPhone, ( amazingly the iPhone was supplied by them and who would thought of opening up the iPhone to check the components when you purchase it?) , they will not recognise the iPhone.
So In a nutshell, i went to the technical centre for help in my weak wifi signal problem for a new iphone and ended up being told that my phone which I just received in nov is a tempered iPhone....

I read on another discussion that sucking air out of the headphone slot works, I tried it and guess what, it worked.......weired....apparently something to do with moisture accumulation....!!!!!!

I have a carrier unlocked iPhone 4 with iOS 6.1. The carrier is Straight Talk. I want to restore it, if I do so, will it delete my APN profile?
