While FaceTiming using my new AT&T iPhone 11, the phone disconnects from my home WiFi during the FaceTime, then reconnect as soon as I end the FaceTime. All software is up to date as of this posting.
iPhone 11
OK so before I start explaining the fix. Let me first start by saying that I followed all and any solutions that was out on the web in terms of turn off this setting and turn this on and log in/out of this and etc. Nothing worked!!!! So I was able to finally get a really good expert person at Apple with 11+ years experience. This issue is related to anyone that may have done a transfer from iPhone to iPhone. The issue is that when backed up its pulling in corruption and causing the FaceTime to work properly. Good news / bad news is: Good news, there is a fix. The fix is to reset your phone and wipe the phone completely. When you restart the phone install as a new setup and not from a backup. The bad news is that you have to set it up as a new clean install and will need to re-download most of your apps. There are some apps that are standard that will pull just simply from cloud and things like your contact list and etc. I tested FaceTime on new install and it worked without any issues. It sucks because I have a lot backed up and now I had to reinstall a lot of my old apps and settings but it will ensure you have a clean backup moving forward and not a corrupt. Let me know how it goes for those that have had the same issue with FaceTime like I did (where wifi would drop as soon as it connected).
There's a fix for this by turning off Wi-Fi Assist from Settings/Cellular - scroll all the way to the bottom, then turn off Wi-Fi assist. I tested and FaceTime works as expected!
There is an update available. Made available last week, 13.4.1. Mentions a FaceTime fix. Hopefully this is the fix for this thread.
I found turning of WiFi assist worked for me, I stay connected to WiFi now during FaceTime. My phone is an iPone 7Plus, latest iOS (13.4.1)
Coincidentally this bug has again reared its ugly head over the last few days, so for me it worked for about one week. I’ll try the same 'fix' (toggling Auto Date & Time) again and see what happens 🤞
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.
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.
now on 13.4.1 and had this issue last night, ended up turning of my Mobile Data and miraculously WiFi stayed perfectly connected for the next 1 1/2 hours of my FaceTime Audio call.
I am on IOS 13.5.1 I don’t know why but my iPhone 7 Plus stays on WiFi now. It was disconnecting but no longer. The only change I’ve made is to turn WiFi assist off.
I have the same issue with my old, otherwise trustworthy iPhone SE. A temporary solution that works for me is to disable cellular data for FaceTime.
Making some progress...
I installed and control my office Wi-fi (plugged into an ethernet jack), but I don't have access to the main router/gateway in the building. I suspect ports are blocked and causing FaceTime not to work. Screen sharing has never worked using my work internet - I suspect that's a port problem as well.
Found this article on FaceTime and ports: https://support.apple.com/en-us/HT202078
Of course, can't speak for everyone, but it's leaning toward blocked ports for me and nothing hardware or iOS related.
Same problem here.
I tried disabling cellular connection and Wifi is not disconnected during FaceTime. Is this a bug?
Regards
When this happens i usually end the call and hit the cellular button and turn cellular off, then wifi stays on. that’s the only way to get it to work.
People stop, just turn off ur mobile data off while you are home. Like this problem is solved temporarily. Enough of this thread.
Go to cellular in the setting and switch off the wifi asist . It worked for me . Good luck guys
After discovering I have the same problem on iPhone 8 and my son on his iPhone 11 (both have the latest iOS update) we are using Messenger with no connection issues. I really don’t understand why FaceTime is so flaky!
