iphone 5 wont stay connected to wifi

My router runs on WPA...

Well I also went into apple today. Bloke looked at my handset and said I just need to go to settings and reset network settings. This sounding too good to be true I asked if he could detect the store wifi and do it....Jon trying he couldn't even get it to register there was a wifi network so pronounced it as broken!!

They offered replacement but it won't be the se serial numbers etc so has recommended I get my network provider to send me a new one....so that's what i've done! Hopefully it won't take too long....

We got 2 iPhone 5's in the house, both drop wifi after a short whole and both won't automatically reconnect if you leave the wifi area. Also still have our old i4's and an iPad on ios6 and they play fine still, do its not ios6.

Bummer, come on Apple, this needs to be addressed ASAP.

Here is what I did that has fixed this issue for me.

Goto Settings.......Wi-Fi.....and make sure Ask to Join Networks is set to ON

Shut iPhone down and then start back up.

So far so good and it has bee almost 24 hours. One family iPhone stayed in WiFi all day and kept it's connection and the other family iPhone left the house, reconnected upon return and has kept the connection since.

Same here. When I first ran the setup and entered the wifi key, I got through the setup and then it "forgot" the wifi. But, as soon as I reentered the key and switched on "ask to join" it has kept wifi since friday. I haven't left the house yet but it hasn't dropped the wifi so far here. Just after the first setup before switching on "ask to join".

Good luck to the OP

I am having the same problem, everytime my iPhone 5 goes to sleep it disconnects from wifi and when I pick it back up to use it, it is back on Edge. I have to go back into my settings, wifi, and reconect to my network. It is an unsecured network so I know it is not a password issue. I have tried reseting my network settings, restoring the iPhone through iTunes, forgetting the network and readding it, tuning on and off the ask to join networks....and am STILL having the same problem. I have spent 2 hours on the phone with apple already and am calling them again now. This is very frustrating to spend this much on a phone and it not work as well as the 3Gs I got rid of.

I'm also haveing same problem with my new iPhone 5 it won't auto connect to my wifi, but it will auto connection to my friends.. I have done all trouble shooting and still nothing.. My iPad 3 with os6 connects fine so could I have a bad iPhone?

I am having the same problem. It is also effecting the mac laptop i believe through icloud linking them is anyone else having this problem and does anyone know the answer

I am having the same issue. Disconnects from wifi every time the phone goes to sleep. I ordered my phone online. Took it to my nearest A T & T store this morning. They refused to exchange. Said I have to wait for a fix from Apple. Very disappionted.

The following was on the support page and so far it has worked for me. I have not been disconnected when the phone goes to sleep the last few times. Go to Settings....General.....Cellular. Toggle Cellular Off and back On. Restart phone. Also, make sure "Enable LTE" and "Data Roaming" are ON. Hope this helps some of you.

just got back from apple store and they did a restore on my phone and they had no problem auto connecting to there wifis, i told him that i am only having a problem auto connecting to my home wifi, he told me that this is a known problem and apple is working on the problem so we just have to sit back and wait till they attack the proble, for the meantime i need to make sure to turn wifi on my self 😟

Well I've fixed both of mine.

Here is what I did, no idea why it would fix it, but they are both working perfectly now.

Turn on "ask to join networks". Let it do that once next time it disconnects. Then turn off cellular data, leave for a minute then turn on again and then turn off "ask to join". Fixed both of mine.

It seems that when you turn on "ask to join" it will fix the problem. If not then make an appointment to the genius bar and get a replacement. Even though that may be out of iphone 5s for sale, they still have replacement iphones for these kinds of problems.
