My iPhone 11 disconnects from WiFi while using FaceTime (video)

All I can do is echo this sentiment and applaud the delivery – thank you, @J-in-Toronto. I have been a loyal iPhone and iPad customer since the 3G, over 12 years ago.

FaceTime is one of Apple's core ecosystem USPs and it is chronically broken for a serious number of users. Or maybe those of us suffering with this issue really are in the insignificant minority. Because Apple clearly does not care enough to fix or even acknowledge it. This is customer service at its worst.

I am experiencing exactly the same issue on IPhone 12, Software Version 14.3.

Is there any resolution on this topic. It is very annoying as I am always dropping back on Edge which doesn’t really allow a proper conversation.

Almost a year and a half later and this issue still has not been fixed. It’s affecting everyone I know who has an iPhone, but watch Apple create a post in 2 years saying it’s only affecting “A small number of users”. They do this all the time

I have an iPhone 12 Pro Max on the newest IOS 14.4 and this keeps on happening. The call keeps on dropping to poor connection and goes to LTE instead of wifi.. Super annoying then the calls start to go to reconnecting and even fail. Additionally, anyone else has the issue of the iPhone 12 not charging. It charges and then stops and then starts again and keeps doing this. Ill only be able to charge about 70% even when I leave it overnight.

The only time I have this problem is when connected to captive WiFi. It did not happen to my 6s which had a Qualcomm modem. Started happening when “upgraded” to the XR with an Intel modem. Was hoping that upgrading to the 12 Pro with a Qualcomm modem would solve the issue but it’s just as bad. It always happens when on captive WiFi and it’s every time I try to use FaceTime. Seems like a bug in the Modem firmware. About to go back to the 6s.

Sadly I have IOT (lighting) tied to a 2.4 Ghz network (it only functions on 2.4 Ghz) so I cannot do this.

Wondering if a device update has solved this for anyone. Has anyone avoided this bug with newer iPhones (12 series?) I have an 11 Pro. I'm in Facetime meetings daily and it's been such a nightmare.

I have an iPhone 11 Pro and I’ve had this issue since I purchased this phone. I always thought it was my wifi, but this issue happens no matter what WiFi network I am connected to. I always have to use my iPad to FaceTime people, because it is the only device that has a stable FaceTime connection.

I upgraded from the iPhone XR to the 12 Pro thinking that it was the stupid Intel modem causing the issue and the issue of not being able to use GPS with cellular data turned turned off but I was wrong, still happening with the Qualcomm Modem. I miss my iPhone 6s, sure it was slow loading games but didn’t have these silly issues. I would switch back to my 6s if the the Touch ID wasn’t broken. My daughters 7 and my wife’s 8 also do not have these issues. Almost seems like a racket! In cahoots with the carriers much???

I don’t have wifi assist on and will not turn it on until Verizon actually becomes truly unlimited which is likely never. Only solution is to turn off cellular data for FaceTime. Almost like FaceTime is always on wifi assist. Btw, wish there were separate options for FaceTime audio and FaceTime video. Also, this only happens to me when on crappy hotel WiFi which further points to FaceTime having an internal WiFi assist bug/switch.

Hello everyone, I think it’s something with 2.4Ghz Vs 5Ghz connections on our routers…do you guys have the auto switch type of wireless routers where there’s a single WiFi network and the router chooses 2.4/5 for your device? I have AT&T fiber with the AT&T provided router that does auto switching. I find it does a terrible job. I’m curious if I pick up a new Wifi 6 router with mesh networking (that is HomeKit compatible) will the issue persist?

I still have this problem on an iPhone 12 Pro Max running iOS 14.7.1. It seems to be a consistent problem when using facetime and Bluetooth. Given the ubiquity of Bluetooth headphones its long past time that it was resolved.

iPhone 12pro, latest iOS.

I don't think this is a bluetooth issue (at least for me). I have tried using Airpods as well as the iPhone speaker but the result is the same: start a FaceTime audio call and the phone switches from full strength Wi-fi to 4G. End the call and Wi-fi is back on.

Just noticed this doesn't happen on my home Wi-fi, only on my office Wi-fi (which I set up). Some folks mentioned 2.4GHz vs 5Ghz or turning Wi-fi assist off. I'll play around and post what I find, but it seems router related?

In any event, it's annoying.

I’ve come to agree that its not Bluetooth related. Turning off cellular data while using FaceTime with Wifi seems to work for me so far.

If I can reproduce without cellular data I’ll try the router next.

I agree that this is an appalling bug since 2019.

I have the same problem. Wifi randomly disconnects and reconnects while on a facetime call. I think it’s a bug in iOS 13. I am using an iPhone 11 Pro Max on iOS 13.1.3.

Well I guess lets hope the updates fix it eventually:) I saw this morning there is another update, unless im late to the game but we’ll see!
