iOS 11.4 - Wi-Fi and Bluetooth no longer function

Restore iOS using iTunes. First try restoring your backup; if that does not resolve the problem restore again and set it up as New. And if that doesn't fix it, take it to Apple: Genius Bar Reservation and Apple Support Options - Apple

Go to settings and open your wifi. Select your wifi by touching the wifi name. Click on Forget This Network. Touch Forget this Network (in red to confirm). Then open up WIFI to rediscover your network and re-enter your password for your network.

This fixed my WIFI issues on iphone 6 plus and iphone 8 running ios 11.4 so far.😉

I found a way to make iPhone Bluetooth work is to turn off the Bluetooth in your ipad then turn on bluetooth in your iphone. Worked for me. I tried every suggestion listed here. Then I turn Bluetooth off in my iPad. iPhone worked

Apple 11.4.1 release issues with Wifi Bluetooth etc.

Phone: IPHONE X

Ever since this 11.4.1 update has come, none of the bluetooth devices work the same. Car bluetooth acts funny sometimes don't connect, bluetooth audio to other devices dont work. With some devices it can't connect anymore. Wifi tethering don't work any more. All these issues were not there and have started to do this because of this release.

I hope they come up with this fix soon. Please don't bother resetting your phone and all that because nothing works. Setting up as a new phone will also not work as this is a software issue and Apple needs to take responsibility and fix this bug.

I'm sorry that YOUR PHONE has this problem. But, believe it or not, the fact that your phone has a problem does not mean that the other 500 million phones on 11.4.1 do. "They" will not come out with a fix, because "they" have no idea what is wrong with your phone. If you make a genius bar appointment, however, they can look at your phone and perhaps fix your phone.

What have you done to try to troubleshoot it? You don't have to, as Apple will if you take it to them, but you might be able to save a trip by doing some basic troubleshooting.

I don't think it's the phone it's the software. I'll tell you why.

I have another IphoneX which had 11.4 and it was working just fine with no issues.

After I had the issues, I did everything which they suggest but it didnt work. (reset the phone, erase all settings and all that but nothing worked).

Just to experiment, I used the other phonex with 11.4 and tested all functionality on that and it was working just fine with all bluetooth settings and everything. Once I upgraded the phone to 11.4.1 i started doing all the things which the other phone was doing (nothing worked). So it's quite obvious that it's the 11.4.1 software upgrade which caused this issue.

You are NOT the only one. 11.4 and 11.3 are a nightmare. Unbelievable that these problems occur unless they are intended to. So many people I know that have Iphone users for life are changing to android. As in

Many. Wish support were more helpful in fixing .

Turn off any other Bluetooth device nearby. Other phones, IPads or speakers.

Having an other Apple device sending and receiving signals nearby effects your phone.

You can notice this when searching for the device you want to connect, other phones and computers appear on the list, but not the one you want. The Bluetooth works, but gets interfiered by the other devices sending in the same frequency.

When the connection you’re after is saved. Turn the other Bluetooth devices again.

Do you know what they are? If the are Bluetooth LE devices such as Tiles or other IoT devices they won't show the name until they connect again. If they are paired devices tap on the i next to each one and forget the device, then pair it again.

Similar issue update Friday to 11:4 no prob with wi fi but Bluetooth not working like it was yesterday I could connect to all discoverable devices yesterday today it won’t find any have restarted the phone muktiple times. Reset net work settings. Reset the entire phone Multiple times, turned the blue tooth devices on and off multiple times nothing works happens every time you update apple products are crap

Having similar issues with iPhone 6, iOS 11.4 and Bluetooth. When BT is enabled on my phone, it’s either really slow or just hangs altogether. Turn off BT and everything seems to work fine. Also notice that my battery drains much faster with BR on versus off. This was an issue even with 11.3.1

Hi,

same problem here.....

Recurent problem with bluetooth when a new update comes out.

FRUSTRATING!!!!!!

My Iphone and Ipad are impacted. Not really willing to go for a full reset...

How can this be that Apple systematicaly fails with bluetooth?

Already when upgrading to iOS 10, I've lost the volume control of my BT speaker...

****, this is really a shame.

Hi also having this problem after IOS 11.4 upgrade.. NO wi-fi or bluetooth , wifi button greyed out and bluetooth spinning wheel.- now what APPLE???

also starting to second guess iphone's and I am a Iphone fan but these upgrades just seem to be causing more problems.

Well Laurence, the person you replied to seems to be the “only” victim among many many more...

My iPhone was forcibly ‘upgraded’ last to the latest version of IOS (which I had repeatedly avoided loading) when the system loaded the update without my agreement. Now, the Bluetooth which worked perfectly before the update just has the perpetual spinning wheel and won’t turn back on at all...

So, it appears that I too am the ‘only’ victim of these shenanigans. Apple should be required to repair these update inflicted issues for free as a service since they don’t give you an actual option to refuse these updates and these updates break things every time.
