Wi-Fi not working on iOS 8.4

just want to share. I have iPhone 4s 2 years old, got wifi grey out 1 year ago, after update to iOS 7. I update OS with itunes, which really slow and mus dowbload full 1 giga. Also i downloaded app with itunes, even updating, which actually redownload the game.

1 month ago, when i use ios 8, i tried my wifi. it only can be connected for a couple seconds. tried open youtube and wifi repeatly turned on / off till crash. then when i turned my wifi, it will cause not responding.

one day, when i charging my iphone, i tried my wifi again, and its worked! i played vainglory 5 matches. on next day, it doesnt work... i thought my wifi can be work if charged but it is not. Then another day, after i play vainglory with cellular nertwork, i tried my wifi and its work. then i did an experiment, the result is my iphone must get warm enough in order to use wifi. so each time i want to use wifi, i played vainglory with cellular network. but if the iphone get colder, wifi will stop working, and can be used again after get warm.

so, thats strange. But now my wifi is work 100% how? i dont know. it happen after a trip with airplane. before thaf, on airport, its still same, must get warm enough. i downloaded GarageBand, put iphone in my pocket. Then after finished download, the wifi turned off by it self then i turn on airplane mode. after arrive, i check my wifi and it work even when my iphone is cold.

so thats my story, sorry for my bad english and typos

While this may not work for everyone, it is a workaround that is working for me. Go into Settings/Privacy/Location Services/System Services and turn off Wi-fi Networking. This is not a service I need enabled and since I have turned it off my wi-fi now stays connected continuously, no more drop-outs. Why this is so is anybody's guess!

I tried all the possible solutions suggested on this thread and no luck. This is really annoying and it's a shame for Apple. Why don't they clearly admit that there is a problem with WiFi on this device/OS? I first experienced this problem on iOS 8.2 and back then; resetting the network settings did the trick. But now with 8.4, I started to experience the same issue and this time nothing helps. I even restored my phone from a backup using iTunes but still the same problem. I spent so much time and effort on fixing Apple's "bug". I tried changing all possible WLAN settings of my route. All of my devices including my old iPhone 4 connects to network with no problem. But my iPhone 6 keeps saying "incorrect password". By the way; what kind of error message is this? Clearly I'm typing it correctly, really really annoying -.- I don't know what to do. This does not happen only at home. It connects fine at some networks (e.g. work) but this happened to me at several places. As a last hope; I'll take my phone to Apple Store and ask the geniuses for help.

have you tried my trick? Before that I also have that problem. I believe after iOS 8, they changed wifi grey out to not working (incorrect password or cant connect). Just try make your iPhone warm enough by using cellular network and play online games .

MY iPhone 6 plus also would not download wifi with 8.4. After many tries Apple gave me a new phone. It worked fine until I updated to 8.4. Could not connect to Apple Extreme nor make or receive phone calls..The phone was useless. After reading these posts tried once more to call Apple. The tech suggestedI call mr internet provider---Cox. The tech said my new modem had a built in router and gave me the password for that. Bingo! I now had wifi. It seems that 8.4 does not support all routers. Apple has to fix that. I suggest that you contact your internet provider. They might have a solution till Apple fixes this.

I was running iOS 8.3 and getting internet speed tests of 95+Mb on my home 100Mb service. Now after the update to 8.4 20Mb if I am lucky. This was the worst update I have ever done.

I found the answer!

I've had this trouble for almost 2 days, can't connect to wifi at all.

Trid all the solution, non of them works.

This is what works for me: SET THE IP ADDRESS MANUALLY.

Maybe it's got the other device use the same IP Address as you.

1. Go to Setting - Wifi - Click on your wifi.
2. Copy the info on DHCP tab to the static tab, except for IP address. If DHCP is blank, look it from another device that could connect, in my case I see it on my iPad.
3. On the last 3 digit, you could choose from 2-255 (1 is for router, afaik). Choose the random number like 189.
4. Click renew lease, and back.
5. Voila it work like before! Not have disconected anymore!

Remember, this is just one solution. Maybe your problem isn't same as mine. But maybe it will be useful for someone. 🙂

Thanks everyone! I've tried everything people suggested, including this new one on the static IP and nothing worked. I have an appointment at the Genuis Bar tomorrow. I hope they can fix it.

I was having the problem on my work network as well this morning. (I don't normally use this just wanted to verify.) I went in and did a reset of the network settings, re-authenticated and was getting the same performance that someone else was getting. Seems to have fixed the problem. I will test at home this evening and see what I get there.

Hi. Any idea what you can do if the phone won't even find the network?

Another issue screen started flickering. iOS 8.4 is very unstable release.

Not for everyone though, all my IOS8.4 devices work perfectly.

Sometimes ranting is therapeutic. For example, I was informed that my family has blown through 50% of our data plan in 10 days. Guessing I was the main culprit since I recently discovered that my brand new iPhone 6 Plus started dropping the WiFi connection at random times - but I unknowingly kept downloading tunes from Apple Music. Been through this many times before with Apple - on my Macbook, on my original iPhone 5 (which was replaced under Apple Care which solved the problem) - on my Wife's Macbook - on a very short-lived Mac Mini running an early build of Yosemite. All this is to say that there has been no common villian. Sometimes it has been hardware, sometimes software. Sometimes router settings have resolved the issue. Sometimes I don't know what resolved the issue. This just seems to be part of being in the Mac ecosystem.

Hi all

I experienced the same wifi problem on an iphone 6 and an iphone 5s on IOS 8.4. Reboots and reset of network settings did not help. I changed the language away from English to another language (UK english also fine) and changed it back to English. After that I could reconnect to the wifi.

Kind regards

Hi,

After reading your post I disabled my WIFI and never touched it again.

However after waking in the morning I discovered that WIFI is greyed out in the control center and cannot be turned off. Battery is draining fast.

This would be fixed sometimes by force restarting the phone.

Previously, application always crashes like chrome and had random restarts of phone.

I also cannot connect to WIFI, "incorrect password" is being displayed though correct password is inputted

I have tried resetting the phone several times and also erase all settings.

Experienced this after updating to ios 8.4.

Iphone 6 plus user here. My girlfriend also updated her phone to ios 8.4 but does not experience what we are experiencing.

VERY FRUSTATING for a first time user of an Iphone.
