Iphone 4S wifi problem

iPhone 4S is having severe problems airplaying thru a network to airplay speakers. Long thread on this here: https://discussions.apple.com/thread/3413370?tstart=0

Chiming in with same issue here. Two new iphones 4s - both dropping wifi on daily basis. I have new Motorola SB6121 cable router paired with new Airport Extreme. My Mac Mini, Macbook Pro, + Macbook all connect without issue. Our old iPhone 3s connected without issue. Have tried resetting router and airport as well as network settings on iPhones. Resetting the network on the phone worked the first half-dozen times, but now my phone won't join at all - I simply get the dreaded "unable to join the network". I also tried turning off "Setting Time Zone" as suggested in earlier post without any luck. I am spending way too much time on this...frustrating.

Sharing my experience with this issue.

I would get the "connected" issue as everyone has described very well by now. In quotes because the signal bars say I'm still connected, but not really. Problem seems to show it's head when I'm at the fringes of wifi coverage. I got a good chance to experiment with this because my master bedroom is where the edge of coverage is and I get to try each of the settings every night and morning. It cut out on ever session every time.

Static router channel (along with moving the channel around) didn't help. Next night I tried IP address reservation on my router and voila. No more disconnections.

Not saying this will fix your issue, but it did for me. Alas, the one thing I could complaint at is no longer an issue. After years of owning different brands and models, I finally have the PERFECT phone.

Thanks Apple!

I had the same problem.. Tested on 3 different netgrar routers..

I ended up buying an Airport Express which resolved it.

Hi Otto,

I have the same equipment as you. I posted earlier that the only way I could get around this was to setup a guest id on the airport and sign in through that. This has solved the problem for me completely.

Now, Ideally I would like Apple to fix the dam* problem, but this has been an effective workaround for me.

Thanks for the tip. I did try signing in on the guest network without any luck. My goal is to be up and running on the main network so I can use my mobile air mouse to control my mac-mini home theater. Went to the Apple store and was given a "new phone". I will test at home and report back.

I have noticed that my new 4S drops out AFTER it has been to sleep.... I wonder if there is a bug in the reawakening code for the WiFi??

Just returned home to try the new genius-supplied iphone 4s on my home Airport Extreme....no luck / no connection. It connected at the Apple store and at work.... I guess this means, in my case, it's a problem with the Airport Extreme? Frustrating. The whole impetus for buying the Airport was to stay within the Apple ecosystem in my foolish assumption that we would avoid device/network compatability issues....

I don't think it's your airport, man. I was having the exact same problem, with the same modem and router. It's quite clearly an issue with the IOS 5.

Try reseting your phone from scratch, and signing it in through the guest network. I know you said it didn't work before, but maybe a reset will do the trick.

I know, it's really frustrating.

I think the issue is with certain iphone 4s's! I posted a few weeks ago about my experience with the first iphone 4s that I got, took it back and got a new one and I have had zero issues with it! Same router, same IOS 5, just different phone and no problems whatsoever!

So I just did another hard reset on my Airport Extreme...and it appears to have solved the problem.

I now have full wifi connectivity with the new iPhone 4s...and all my other devices. So far so good.

I am using a 5th gen Airport Extreme. If you are using the same, you might try the hard reset again.

Glad to see I'm not alone with this problem. Can't help but feel I've upgraded in a phone from 4 to a 4s but downgraded in its capabilities. Wifi continues to lose connection even after trying all of the suggested steps, restore, reset network settings, change router settings etc but still getting the same problem. No wifi means I can't FaceTime anymore too. I never experienced this problem on my previous apple devices until now. If this is a software issue, why was it not effecting earlier devices? At least if Apple recognised our issues on this subject and are working on a fix, then I'm happy to patiently wait for it to be fixed in an update, but for me personally, it's the not knowing if this is on the fix list that bothers me most, these are not cheap devices so it would be nice to have all the features it should be capable of actually working, especially something as common as wifi technology!

Please Apple, this is a major problem for the majority of us, so at least acknowledge there is a problem and that it is being looked at....... Soon!

Have you tried this yet? It was posted on a different thread and I did it and it has worked for me. I was unable to connect on public or my home wifi before I did this.

I went into settings. touch WIFI.. choose the network.. then touched the small arrow on the right side. A new page opens and at the top I touched the box "forget this Network"

I then did a complete reboot. When the phone came back, I choose the network again it worked like a charm.....

Hope this helps......

Yes, it works for me as well!!

I HAVE FOUND A SOLUTION TOO MY IPHONE 4S WIFI PROBLEM!

At first everything worked as it should out of the box. I used my WiFi for Safari and E-mail and such. But then it seemed like “WiFi froze” as some people have described it on the forum. I then began to investigate the problem and many people on the web seems too have the same WiFi problem with Iphone 4S and also some with Ipad2. That made me somewhat unhappy because I like my new Iphone 4S and some people seems too think that the problem is with the new IOS5 or a faulty hardware.

There might be, as with all products on the market, some Iphones with faulty hardware and for those my solution will not work and you probably have too get a new one. But for most of you I would recommend you too try my solution and it might work for you as well. Probably there are more than me with this solution but I have not seen it anywhere online so that’s why I post it too help out if I can.

My WiFi problem was linked too me using Skype on my Iphone. And after a quick look at the log in my router I found that by some reason the Skype app somehow got my Iphone blocked when my router analysed my traffic. The symptom was that my router locked out my Iphone from the Internet for a period of time. If this have anything too do with just Skype or that in cooperation with IOS5 I don’t know.

As some people tries too restart, reinstall and a lot else as described on this forum I would imagine that your routers in the meantime removes the ban it has imposed temporary for your Iphone. When you get back on WiFi you get blocked again.

Now you might say “I do not use Skype nor have Skype app on my Iphone”. Too those people I would say “Lookat your traffic between your Iphone and your router as it might be another app causing a lockout on your router.”

The solution part I (what I did):

* Enter your router settings.

* Allow your Iphone free access too the Internet on your router without router interference such as traffic analysing. Here you may need too have a look in your manual for your router how too make this possible. I put my Iphone in the DMZ (demilitarized zone) (using a D-Link router). The DMZ lets traffic flow without router interference.

* Restart your Iphone.

* Now you should be free of the WiFi problem.

The solution part II (what I will do later on):

* Try and isolate what causes the router block so you can set up the router too work with the Iphone without using the DMZ-setting as DMZ is viewed as a last resort when all else fails. If you for an example put a computer in the DMZ you will not get protection from the router as you go online.

* Will try a couple of things, might be the SPI (stateful packet inspection) on my router that generates these lockouts. As DMZ traffic isn’t screened by SPI.

Some thoughts:

When I am in another room my signal drops too 18 – 25 % as for when at router it is more like 85%. So if you are away from the router check the signal strength, usually shown in router settings.

Hope this helps you with your problem.
