Q: iPhone 5 wifi issues

changing your security setting on your wifi to either WPA Personal (not 2) and/or WEP will probably resolve the issue. I think this is a software issue that iwll be resolved with an update soon. that is if Apple is listening...

I will share with you for FREE what I paid $40 smackaroonies for!!  I contacted NETGEAR for help with my WIFI ROUTER, problem solved!!  It was the simplest grade school technique I ever seen!  Biggest problem was understanding the guy over the phone, they are in INDIA!!  Ready to fix this?????? Here we go:  In your ROUTER settings, change the login/access ID Name used for devices to find the router... EXAMPLE: Instead of "Wingstat7" change to "Wingstat07" and then FIND the WIFI on all your devices.  You can use the same password if you want.  My guess is that factory settings in most routers are predetermined to block or deny certain devices after a certain amount of time and or when NEW devices are added.  They wanted a 6 month service contract and to monitor my system for me... from INDIA!!  DECLINED!!  Hope this helps ;-)

Have two new iphone 5's - one worked perfectly, the other no wi-fi.  Wifi would connect for possibly 10 seconds, then not transmit any data.  Took it to Apple Store this morning (worked just fine on the store network), swapped it out, and now everything works fine. Before the swap, tried most of the things mentioned here with adjusting router in various ways (Belkin router, WPA2) but nothing worked.  So far both iphones working fine with original configuration of router.

does anyone here understand the console logs. I took this just now:

Do you think these 'Network changed' logs are related to the problem?

For what it's worth just replaced mine (they had replacement stock, although software assigned to carrier which was interesting) and it works fine. Apple Store still a zoo, but ultimately pretty happy with how it all went down. Possible that a software patch will introduce a workaround but I'd suggest going and getting working hardware.

I will share what worked for me. I changed the 5 Ghz and 2.4 Ghz bands to same router name and also changed the channel the wifi was on. I recommend changing channels and applying settings on router. It eliminated my problem. This usually cures most wifi issues in my household.

So, phone swapped at Apple Store and it works perfectly. Word of advice don't get an exchange new phone get a replacement from the genius.

What do you mean exactly? Wouldn't a replacement one be a new one?

you know..saying things like "Biggest problem was understanding the guy over the phone, they are in INDIA!".. is not only racist but stupidly unneccesary....considering 1. he speaks 2 languages.  2.  they are used to british accents so you are probably the one hard to understand  3. the guy not only solved your problem .. but as you said "It was the simplest grade school technique I ever seen!"   I bet you are a republican.

Next time you have a problem...don't call the Indians to help you.. just buy a new phone... because obviously Smart phones aren't for you.

Good points but maybe a tad too strong in the wording.

Hi, what I meant was that the phone is within two weeks of purchase so you can get a total swap of a new retail boxed one or one from the Geniuses that will eventually be refurb end ones but since the phone is new, all phones are new. I have to think that the genius replacement models are bug free.

Strong Indian accents are hard for me to understand over the phone as well.  Lets stay on topic.

My wife and I are having wifi issues as well. iPhone 5, White 32 gig, and Black 64 gig.  Both are able to have a semi

stable, if slow, connection to the 2.4 ghz band but will not hold a connection on the 5 ghz band at all.  Every minute or

so the phone reverts back to LTE, then after a short time will go back to wifi. 

We are working on some network tests right now, but this is obviously a iPhone 5 problem as both iPad 3s are using the

5g band flawlessly.

Just wanted to add to the post count so that hopefully apple takes notice.

If I find anything that works I will post, but to be honest, I'm not too hot on the idea of mickey-mousing my network

when this is obviously on Apple's side.

Sorry for the bad format. I can't find an edit button anywhere -_-.

I just got off the phone with apple after about 3 hours today. the thing that i found for my situation is that any download that is initiated with wifi can end with LTE. my problem was downloading music from itunes match. i started downloading a bunch of albums with wifi, and when i went out of range, instead of stopping the downloads (even though cellular data was turned off), it continued with LTE for a bunch of albums and blew through a bunch of data - more than my plan allowed for. call apple and let them know you're not happy about it, and im sure they'll get everything squared away (fairly) quickly.

Well, went to the Apple store and they swapped out my handset for a new one...works on wifi beautifully!

Sees all the access points in the neighborhood, my first handset wouldn't see my own router unless I was in the same room.

This confirms to me there was a hardware issue...maybe a bad wifi radio?

I'm happy.  I'm also curious to see how apple handles the growing number of upset customers.

Good luck all!
