Suppose one restores as new on a different computer, which no one has yet authorized? I'm guessing, since my replacement came with 6.0.1. In any case, it may help to restore as new, and if one is careful, can't hurt. This is what Apple told me to do, but I got out of it because I had to go back to the store the next day anyway for hubby's 4S. Got a great tech who offered me a replacement for my phone.
Sk8dreams: already tried restoring it to factory settings, but i stays on 6.0.2.
JimHdk: Before going to Amsterdam I would like to try a newer version of iOS, to see if this solves the isue. I know that most of the iPhones do not have these problems (I bought two iPhones: the one I kept for myself has problems, the other one works flawless, on 6.0.2), but since the problems occured after the upgrade I somehow am convinced that it is software related.
Not sure if anyone is having this problem....
Over the holiday I got an iPad Mini and iPhone 5. On both devices my wifi disconnects often, especially when put into lock mode. I had to keep re entering password to reconnect, very annoying.
I read the discussions and had a thought to solve it. This fix works on both my iPhone and iPad.
Go to your wireless settings and disconnect. Then select any other network, one that you do not want to connect to.
Connect to the random wifi network and when prompted enter a password. Just make up any combination Of letters and numbers until the join button pops out in blue. Click join.
Obviously it will fail and tell you the password is incorrect. Back out and now connect to your wifi network.
That's it, problem solved. Both my iPad and iPhone now automatically reconnect to my network when I unlock device.
I got a replacement iPhone 5 from O2 UK today.
Though my experience with the new phone confirms my suspicion that it is a hardware issue.
My plan was to not upgrade to 6.0.2 and use the phone with default OS for couple of weeks to make sure wifi works properly and there is no hardware issue.
BUT with 6.0.1 it's **** slow
Therefore I upgraded to 6.0.2
No Change, its still **** slow. wifi signal level is so low that I can notice the wifi icon at the top status bar dropping to two levels.
Next time may be I should try a replacement directly from Apple.
I restored the iPhone as new via iTunes. But the result is the same:
at home the wifi works flawless (although the reception is not as good as on my iPad),
3G is still too slow.
At work the phone connects to the network, but download speed is "medieval".
So once again: in my case I think it is software related (if it were hardware related, I don't understand why the phone works without problems on one network and bad on some other networks)
(I know others have not exactly the same symptoms, so in their case it might indeed be hardware related)
Here's an odd one...
I hadn't noticed any problems with my WiFi after I got a replacement iPhone 5 - I was always able to connect and speed tests seemed good. But last night I was trying to watch a video on my phone via AirPlay to the Apple TV, and it had to stop and buffer so often it was practically unwatchable. I knew it wasn't the network because we had just been watching Netflix streaming a moment before.
I tried resetting network settings but it made no difference. I tried switching from 5 GHz to 2.4 GHz, and that also made no difference. I walked back upstairs within 10 feet of the router to get something, came back downstairs, and suddenly everything was working fine again. I watched 10 minutes of HD video through the phone without it buffering once. The odd thing is I didn't do anything to the phone during the time I walked within a few feet of the router. Did I cure it just by walking by? Or was it just a coincidence and the "forget network settings" had a delayed reaction?
I too had wifi issues with my new iphone 5. I got the new phone on December 17th. I used it and thought it was working fine, but it was the week before Christmas, so I didn't get to play with it too much. I didn't notice a wifi issue until after Christmas when I started working out in my new woodworking shop. I have Sonos whole house audio, and it needs wifi to control it using the Sonos app. I have a portable speaker for Sonos out in my shop. I noticed that the iphone 5 wouldn't connect to the wifi when I wanted to control it. I thought I was having network problems, so I grabbed my old iphone 4 and tried it, and it worked fine. I was able to see the networks on the iphone 5, but would get the "unable to connect to network" message. If I went into the house and got close to the router, it connected fine and speedtest.net app showed I was getting full 30mbps/5mbps. If I walked away from the router, it was still connected but my speeds dropped off drastically. When I went out to the shop, the iphone 5 would no longer get anything from the web through the wifi, even though it still showed it was connected and had full strength. The iphone 4 and all other apple devices we have worked fine at the same point. Well long story long, I returned the phone to Verizon today. Got a new iphone 5 and it's working great out in the shop and everywhere else. My question is, at some point on the original iphone 5, I upgraded to 6.0.2. I have 6.0.1 running on the replacement. I'm afraid to upgrade to 6.0.2 because I don't know if that is when my issues started with the other one. What do you think? Should I upgrade to 6.0.2, or could it be 6.0.2 that is causing the wifi problem I experienced on the original iphone 5?
For me, it absolutely was 6.0.2. that broke my iPhone 5.
My WiFi was 100% from the release day of the iPhone 5 and throughout 6.0.1.
So, good advice here - if WiFi works on 6.0 or 6.0.1, DO NOT UPDATE TO 6.0.2. You will gain nothing that is necessary for better operation.
It broke my WiFi, Keyboard Shortcuts, and Notification/Alerts sound levels.
I always update when one is available, but have learned my lesson with regard to the 'if it isn't broke don't fix it' philosophy.
Again, everyone has a different situation here, which indicates to me that there were different lots of iPhone 5's being built with differing parts used in these varying lots. It stinks for Apple, who has to figure how to fix them all.
