Iphone 4S wifi problem

This piece of advice to let it be and adjust itself is excellent. Things do have a way of ironing out with new OS upgrades. The text tones have stopped echoing and my Wifi seems to have stabilized for now. For the last two days I have been stable, no dropped signal in the morning.

Hey i am from New Zealand, got my 4s on Monday and it has been having the same issues as alot of others appear to be having! My mate also has a 4s and got his a few days before me...as soon as he came around to my house my wifi started playing up and when he left it was fine again!! He has a Airport Extreme base station at his place and has no issues in the 6 days he has had his.. I have tried your recommendations with the reset so will see how it goes and let you know!

I had the same problems with wifi after Update to iOS 5.0.1

I've testet some wifi options...

I switched from 802.11n to only 802.11g+b in my Access Point

and my wifi problems are gone

is it only a Wireless N Problem?

I managed to get into my Verizon Fios router and I changed a setting (picture below).

The Firmware is 20.19.8 http://www.flickr.com/photos/renkein/6349970575/in/photostream

And the setting I changed was to keep the channel selection during each power cycle. http://www.flickr.com/photos/renkein/6350716064/in/photostream/lightbox/

And... after restarting the router.... I've had 0 WiFi problems with my iPhone 4s since yesterday after work when I did this. I'm not 100% sure if it was just the restart of the router or setting the channel selection to stay the same per each cycle.... Either way, I'm happy. lol. I've done iCloud backups, web album backups, and surfed reddit again to my heart's content. 🙂 Will post back if anything changes.

Edit: Apologies for the horrible screenshots, took them before heading off to work this morning (almost forgot to take them).

So let's be clear, is this an ios 5 issue (i am still experiencing the same issue on ios 5.0.1) or iphone 4S issue? All of a sudden the wi-fi stops loading anything. Resolution is airplane mode on and off and it works again, or leave it be for a while and then it seems to be better.

I have raised a case with apple and I think I will be getting my phone replaced (admission of a quality issue if you ask me) but I am going to go for it. The fact is a £700 phone should be PERFECT.

I don't think we know enough yet to say that it's the phone that's losing WiFi, or the WiFi momentarily dropping dead because of the phone's misbehavior. See http://forums.macrumors.com/showthread.php?t=1275479 (I'm the original poster)... my wife's iPhone 4S caught in the act of abusing a router. I've since seen similar issues with my son's iPhone 4, also running iOS 5.0.1.

Up in our mountain place, the router there kept rebooting; here at home the router has started spontaneously rebooting... but only when one or the other of those phones is present.

So some questions for you folks:

• Is internet connectivity to other devices in your network affected? ...If so, it's the router having a burp, not the phone.
• Does anyone else have the capability of capturing router logs as presented in that thread?

--S.

Making the suggested settings changes to my Fios router did nothing (technically, since my Fios wireless is disabled and am using an Airport Extreme instead, I manually selected the channels on the Extreme but wifi timeout still persisted). Before I tested it, I made sure the router firmware was fully updated, and I restored my 4S to a new phone to have a clean base just to test the wifi.

For me, this is still an iPhone 4S issue running 5.0.1, as my iPad 2 on 5.0.1 and desktop computers still connect to the internet just fine while the 4S suffers a timeout. I'm not sure if this affects the iPhone 4 on 5.0.1, though.

Here's my logs from an Extreme, the interesting thing is that the iPhone 4S is the only one generating these errors. There are 2 other iPads and some other wireless devices accessing wifi fine while the iPhone is generating these errors.

This is unedited beyond hiding my phone's address, it is just in this endless loop of association/disassociation:

Thank you, Turbostar-- this is fantastic. It is the exact behavior I documented on the MacRumors thread for my two D-Link routers.

It's a big clue. I think you've contributed significantly... thanks!

Adding this to say I've done nothing to my router and I've completely stabilized finally on my 4S. The only thing I did was after the 5.0.1 upgrade forgot my home network then reconnected with my password. I was having a terrible time dropping the connection and it seems to have stabilized now.

How long did it take since you forgot to stabilize? I waited 2 days after forgetting, rebooting router, etc. and still couldn't surf for more than 10 minutes without hitting a timeout.

This ignores the larger problem with this wait method is nothing that requires data works until I turn airplane mode on/off so did you have to do that over 'n over again while you waited for it to stabilize?

Just wanted to publicly add myself to the list of those 4s users experiencing wifi timeout/disconnect issues.

I actually received a replacement iPhone 4s yesterday for the issue, but the problem is still the same on the replacement phone, which indicates to me that it's either an ios5 issue or a big faulty batch of 4s-es.

So annoying though.

Hi,

I had the same problem. The 4S would connect but not transmit afetr a short time, but the 3GS was fine. I read up on it and it seems to be a common problem. The fix is to reset your router a bunch of times until it works. I had to reset my router abiout 5 times but the problem has gone for over a week now.

I know it's not ideal, there must be a problem with the 4S recieving on specific frequencies or something.

This is the only fix I have seen reported that works. Other people have swapped the phone for a new one and still have the same problem. I'm sure its confined to the router and not the phones, however you would ahve hope Apple would have picked this up and sorted it.

Please give it a go and let others know if it works.

Good luck

It was 48 hours. Just turn off Wifi and back on to reconnect, or of course Airplane mode does the same thing. I wish I could tell you I found some key to this but it just ironed itself out. This morning again, for the fifth straight day, I was still connected.

It's worth noting for the guy who had an apple store saying that 7 pages of thread wasn't much that there are multiple threads on this forum about the same thing.

Anyway I HAVE FIXED IT! 😁

Except I don't know how. I re-set the network settings, upgraded to IOS 5.0.1, got it to forget the network, rebooted the router, changed the mode in the router to "g & b', all the things listed here etc but the main thing was on my router I think (NETGEAR DGN 1000SP - the crappy free one that Virgin customers get in the UK). I think this problem might only occur if there are lots of other routers/wifi signals anywhere near you all using the same channel. I have quite a few and what appeared to solve it, although it could have been any of the things I tried, is chosing a specific channel on my router and not Auto. I started at the top (13 I think) and worked my way down. I'm now at 11 and everything is working great all round the house and has been for about 10 days. No more having to have it next to the router and that circly thing forever going round.

Mind you this might be a little like how my wife, when there is in excess of 50 variables, be able without fact, evidence or trial, to pinpoint what has caused a rash to appear on my daughter.
