iPhone 4S signal loss after upgrade to iOS6

I am having the same problem with my iPhone 5 on iOS 6. I updated my iPhone 4 to iOS 6 and did not seem to have an issue until I switched phones on Friday. I assumed it was the phone rather than the software but that could make sense to me also.

Additionally, as I write this I am sitting next to a friend with a 4s on iOS 5 (also on AT&T like me) and they have 5 bars and no connectivity issues whereas I have 2 bars and my LTE connection drops frequently.

I have a 4 and uptdated it on friday...with i OS 5 no problem with the wifi connection...now it is weaker than bevor....

I have "enable LTE" as my option with the 5. As an experiment, I turned off all cellular data and then turned it back on to see if there is any resolution. Unfortunately, I have been having this problem repeatedly at my workplace and my data/signal strength consistantly drops. I work in a fairly large concrete building and I would assume the structure was causing the interference but I have had an original iPhone, a 3Gs, and a 4 in this building with no other issues until I started using the 5. Thanks for the advice though!

Same problem! My 4s worked fine before iOS6 now my signal is awful and calls take AGES to connect, cannot even send texts in places where I always could. This is mad! I have not tried the turning 3G off and on again - if it does anything I will post back. If anyone finds out what's happening or if your reading this Apple please could you fix this error out soon! I like most people use their iPhone for work as well as for personal use so its quickly changing from an inconvenience to a more serious issue. Any help or ideas would be greatly appreciated - Thanks

Hi, I'm having the same problem!! Apple even replaced my phone but the problem persists. This is not only scary but really really frustrating as I need this phone to work effectively (to maintain employment) and it is leaving me dead in the water. Neither Apple nor my carrier seems to know what to do. Anybody out there have any ideas? (My phone has already been replaced, reset, restored, 3G toggled on and off, etc etc and nothing works...the most that has happened is that I've had perhaps 20 of good fast 3G service and then all was gone again.....)

Hi folks,

I've experienced the same symptom - cell bars dropping away then 'Searching' message - after I installed IOS 6 on my iphone 4. The only twist is that I only experienced the symptom when I had a location service-based app open like Apple Maps, Google Maps, Waze, or Scout. I found a fix though! After I reset my Network Settings the problem is gone. Go to General --> Reset --> Reset Network Settings and activate it. The only caveat is that you'll have to reconnect to your wifi-based network (if you have one) and type in your wifi password again. Hope this helps.

The same situation with IOS6.0.1

Apple support!!!!!!!!

HELP!!!!!!!!!!!!!!!

Yep, Apple has blown up this thing. After the upgrade to 6.0.1 my iPhone 4S is not showing up any wifi. Trying to configure it manually does not help ether. In addition to that, you can not downgrade to 6.0, which then really *****. An iPhone without Wifi does not only *****, its useless to me, because 3G is really bad where I live.

So, Apple, please fix this, very soon.

i aslo have same problems

my carrier is always showing me searching

this is all happing after upgrading my iphone 4s to ios 6.0.1

I have the exact problem as well, upgraded to IOS 6.0.1 and boom no signal, the phone is now an iPod, Apple arent doing any justice with this one

Exactly same problem... I have 2 iphones 4 with 6.0.1 when i grab the phone signal gone.. constant call drops.. I was with IOS 5 and I did not have this problem. Why 4 months with this ******* garbage of update without solution?
