iPhone 8 on iOS11 keeps disconnecting from wifi

I have the same issue. The wifi is getting disconnected constantly. I changed my iphone from 7 to 8 plus. With iphone 7 I did not have that issue even though it was with the latest update. I got the iphone 8 plus yesterday and from minute 1 I have this issue. I updated it to the latest version and tried everything it is suggested here but nothing worked. Please help.

I am having the same problem. I just got my 8 plus last week and it’s been constantly disconnecting itself from wi-fi while I’m home. Of course, I don’t notice right away and meanwhile my data is being used up. I have had iPhones since the 4S, but this is the first time I’ve ever had this problem.

Hello Ace16-23

I have contacted Apple Support, spoken with multiple senior advisor's and to my surprise only 1 out of all of them knew about this Auto-Login or showed me that he knew.

Now he told me that it is supposed to work in that manner i.e (Disconnect when iOS device is locked and Re-Connect (2-4)seconds approx. when you wake the iOS device)

Auto-Login -> is used for Captive networks i.e Hotels,Restaurants etc.

Now if it's supposed to work in this manner there are a lot of issues:

1) When Wi-Fi disconnects the Cellular Data turns on that means you are using a Power-Hungry Chip which drains your battery a lot (I have done tests and compared)

2) For those who cannot afford to have a Cellular Data plans or afford to keep their Cellular data on since they may have a limited bandwidth.

3) In certain location Cellular Data doesn't work .

So in my opinion it shouldn't be enabled for every Wireless Fidelity network you connect to!

I have given this as Feedback to Apple and to that Senior Advisor !

If you also have it or if you know others who want a feature change please give feedback to Apple Product Feedback - Apple

Yes everyone contact Apple Support !!

I contacted Apple support !

I tried the following:

1. Restoring iPhone as NEW
2. Restoring using DFU
3. Even Forget Network

Nothing Worked!

And they said that everything is fine at the hardware level ! I don't know ! But this is really crazy that they can't fix this fast if it is a iOS problem !

I am not living in any country where there is an Apple Store unfortunately but will visit an Apple Authorized Service Provider ! Have spoken to countless Senior Apple Advisors !! And they all tell me since I have followed all these steps it is a Hardware issue but I have doubts about that !

I have tried

1. Restoring as New iPhone and not from Backup
2. DFU restore (Downloading Firmware with iOS)
3. Reset Network Settings

Since October and IOS ~10.3.3 I have seen my WiFi connections dropout, causing havoc with my WiFi Calling. I'm on IOS 11 now - which still exhibits the issue.

My symptoms were after approximately 1 minute of phone-sleep, when I reactivated it - the topbar WiFi symbol would dropout in preference of 3G/4G - then re-establish a second or two later. During sleep no incoming calls could establish (which previously they did).

I have two home WiFi networks - one of which the phone exhibited the issue - one which it did not.

Tried changing the settings of the affected AP; Network Reset; hard rebooting the phone; replacing the AP with an Apple Airport Extreme; and factory resetting a phone. Three iPhones in total exhibited the issue - all > 10.3.3.

My SSIDs were 31 and 32 characters respectively between the working/non-working AP.

Obvious in retrospect - but I tried changing the problematic 32-char SSID AP to an SSID of 'Bob' - same long password - and the problem has now gone. A simpler nine character SSID is also good.

Try simplifying your SSID as part of your diagnostics?

Hi,

I have the same problem and this with the SSID I haven’t tried it. It may sound stupid but what is SSID and how do I change the number you are talking about? I’m desperate. I tried sooo many things and nothing works. The phone has warranty and I can return it but it’s my last option.

It's not stupid to ask questions if you don't know. Its the name of your WiFi network. You'll have to log onto your router to change it - but first - look under settings and see if "Wi-Fi" has a long name to the right, or a short name. Don't put-in the effort of logging into your router and changing something to potentially risk nausing-up your entire network if it doesn't look a good-fit for your particular issue (different people in this thread likely have different problems).

Same issue since iOS 11 on iPhone SE. My best guess is that Apple's reply to all the people reporting bad battery life on iOS 11 was to lower the timeout interval for wifi which saves battery but makes background stuff like Whatsapp Web unusable. Such a mess.

Same problem here with iPhone X and iPhone 8, both running the latest iOS 11.1.2

I've not had any issues before with iPhone 6 Plus and iPhone 7 Plus.

Hope that this can be fixed ASAP by the Apple engineers.

BTW, all of you, call Apple Support so that they know that they know it's not 5-10 people having this issues, there are many.

I too am having the same problem with my IPhone 8! Switching from a 6S to an 8 and ever since, I’m repeatedly having to turn my Wi-Fi on and off to get the phone to work. I’ve reset router and reset all network settings. Brought momentary resolution and then starts to get hung up again. I notice it happens more frequently after watching a news clip or listening to audio. Factime is essentially useless with this problem.

If you've tried "every conceivable Troubleshooting Step" then make an appointment at the genius bar and have it checked.
