Q: iPhone 6 dropping WiFi constantly

I have been having the same issue on two new iPhone 6 devices, and it started within hours of purchasing the phone. Over the course of two days, Apple Support asked me to restore the phone to factory settings three times, uninstall iOS 8 and then to reinstall iOS 8. One of those times, I restored my own settings from iTunes and another time from the Cloud, but the wifi connectivity issue kept coming back. As an experiment, the third time I did not then restore any backup, either from the Cloud or iTunes. The only things I did were add my wifi password and gmail to the phone. The phone had no problems with wifi for about 12 hours, then exactly the same thing happened again, with wifi constantly being dropped and no ability to see other networks. I live downtown in a major city, so usually my phone can see up to 18 other wifi networks. In the meantime, my old iPhone 5 running iOS 8 has had no problems with wifi connectivity, although it isn't now connected to Verizon cellular. Apple replaced my phone, and the new phone worked perfectly for about 12 hours, but now wifi is dropping at irregular intervals and the phone is unable to find any networks unless it is restarted or the network settings are reset to the factory settings. Either of those solutions, however, provides only temporary relief.

Thanks for posting this and saving me the time of wiping my 6 and starting over without a restore. 

There are many that are blaming this on iOS8, but I have updated my iPad Air with iOS8, and side by side WiFi speed tests are perfect on my iPAD at ~20Mbps download and 15Mbps upload, while my iPhone 6 is in the Kbps range for download, with ~12 Mbps performance on uploads.  Like others have found, a reboot or network reset seems to fix it for a few minutes, but not permanently.

I've tried the following without lasting improvement:

Reboot

Network settings reset

Google DNS change

Turning off Location Services / System Services / WiFi Networking

Changing my WiFi router channel number around

Any other ideas?

Obvious things to try are to ensure you're running the latest firmware on your router/wireless access point. Are you using WPA security, I've had problems in the past with WEP?

I've attached some screenshots of my wireless setup in case it helps, I'm not having any probs with my iphone6 (I've deleted the ESSID and wpa key from the screenshots).

I had the same problem and I resolved it by manually entering SSID, Type of security WEP, WAP, etc.., and password. Haven't had problems since. It seems to be a iOS 8 thing and not hardware.

I will try these changes, but if the problem I am experiencing is an iOS8 thing, it must be a iOS8 AND a iPhone 6 issue, because my iPad Air on iOS8 performs as good as ever on the same WiFi settings, and WiFi router settings.

Totally agree with you about it being a iOS 8 and iPhone 6. As other devices are not having the same issue.

After doing a reset on the network settings for about the 5th time, my WiFi performance has been back to normal for about 6 hours and counting.  This doesn't make any sense, so I'm not holding my breath.

I Also have the same problem after a couple of hours found out not a hardware issue it's the IOS 8 wifi security it drops on WEP setup on router changed it to WAP and works GREAT this I have tested on 2 iphone 6 plus space gray a 16gb and a 64 gb the only thing that ***** is that if you connect some were that has WEP network  you are going to have the same problem hope they fix this bug on IOS 8 fast course it's a pain.

Hi all, just like you, I had terrible wi-fi ever since getting the iPhone 6 plus, and was very frustrated.

I am so ****** at Apple right now it's not funny. This is my 4th iPhone and my worst upgrade experience ever. Does this company not use Beta testers anymore? So many OS problems! Considering returning my 6 and - OMG - getting an Android. Enough venting... To answer your question:

My WiFi goes from being stable for hours to - all of a sudden - not being able to maintain a WiFi connection for even a few minutes. It took hours the first few times to try to correct the problem. I finally learned that I need to do these two things:

1) Router: reboot it using its web based control software - and - here is the key: not just power cycle it! That did not help.

2) Phone: Reset Network Settings (Settings>General>Reset) Perhaps also power cycle it? I have done that but am not sure it was necessary.

After doing both at the same time the phone has held onto the WiFi connection for up to 12 hours before going glitchy.

Comment: Now that I know this relatively simple fix works at home it's fine, but if the phone can't hold onto networks where I'm a guest (at my office, in a mall...) am I supposed to find and kindly ask the network admin to re-boot their router for ME?  Come on Apple.

same thing.  i opened right out of the box, restored nothing, clean phone, kept disconnecting me from wifi.  does it every 2 minutes.  restarted the router/modem and it fixed it for about an hour, now back to same thing.

i have to put in my wifi password, sometimes 5 times in a row, even though i know it's the correct password.

of course, this starts as soon as i lose my unlimited data, so i keep unknowingly wasting data while sitting in my house.  none of my other devices have trouble keeping the wifi connection.

I changed my hope WiFi router security from WEP to WPA two days ago, and reconnected my iPhone 6 and my wireless connection has been flawless since.

II'm already on wpa. IIs there a way for me to post a video of what's happening? My iphone 4 next to my iphone 6. iPhone 4 sitting pretty w strong wifi signal, 6 going in and out in and out lte and wifi. cinstantly searching and draining my battery. I am NOT happy. I waited 4 years to upgrade and this is worse than any other phone ever. Verizon told me it was my router. It's not. Five other devices, two of which are apple, and have 0 problems.

went into live chat w apple Twice yesterday. Reset network settings, reset all settings, reboot router, completely wipeout phone and restore to original factory settings. Did some kind of test thru a text and did not find any corruption. Nothing worked.  Told me to go to verizon for a new phone.

GO to verizon today. In less than 2 seconds the guy tells me it's corrupted. I swear he didn't even look at it. i feel like I'm really good with technology as I had tried pretty much every fix apple suggested before they told me to try And I'm pretty sure I could gauge that he did nothing to see that. Anyway he is crowing about my phone being corrupted. I told him it was wiped out and restored twice how was it corrupted? Somehow we go from that to oh it's my router, if you had an apple router it would work. Um ok so every person on the planet should have an apple router for an iphone? Sure. Also no other wireless device has ever has this problem in my home. I took a video of our phones side by side showing how all were connected fine except my phone, going in and out of wifi.

HE then then tells me no it's not my phone it's my cloud that is corrupted. The only thing I loaded from my cloud were my contacts. So he tells me my contacts are corrupted. I said really then why arent  my iphone 4 and my iPad messed up? He says it's the sensitive iphone 6 antennae. I said so now my cloud is corrupted w a corruption that only affects my brand new phone's antennae?  This is the circle we went in.

Basically no one knows what's up with my phone and he was just spouting off random answers.

I Sincerely hope it is a software issue and that the next update fixes it.  Thank you to apple for creating this mess.

try getting into your router settings and seeing if it's WEP security. If so, change it to WPA or WPA2. You'll probably have to add wifi to all your other devices as well but yours will probably work.
