iPhone 8 on iOS11 keeps disconnecting from wifi

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

5ghz keeps disconnecting while locked. 2.4ghz doesnt disconnect for me. This was solved before 11 and rose again with 11

Hmmm...

I truly have no clue how to assist you with that.

I can suggest something worked for me too, try to make 2 different wireless SSID names if you have one router that supports 2G & 5G.

@ your iPhone go to DNS - Configure DNS and set it manual.

Maybe it will work for you as I hope so!

Hi

Go to the website for your make of router check for firmware update.

Does this happen with other wifi when you are away from home?

Try a wifi signal booster.

Cheers

Please report this to Apple Support. It’s important that we report these issues.

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.

Not useful ! I tried every conceivable Troubleshooting Step ! And still same issue !

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

This issue drove me nuts today - my iPhone X would connect to wifi at my sister's house for about 10secs and then continuously connect / disconnect for a second or so each.

I tried all the suggestions in this forum and other places, but nothing helped.

So I thought that this may be related to an ill attempt of going into power saving mode or something like that. I connected the phone to a charger, and sure enough the phone no longer exhibits this faulty behavior. Even more, now that it charged to 59% it holds the connection! Could this be related to some of this new iPhone throttling "feature" due to a low performing battery? Just know that I was nowhere close to low power mode, I had at least 35% of battery when I plugged it in.

Any thoughts on this one?

It's the name of your WiFi network. You have to log onto your router to change it...

thank you for the suggestion. The auto join was turned off. I turned it on and the problem on my iPhone 8+ seems to be fixed.

I managed to fix my issue with the auto join option mentioned in other posts on his feed. Give it a try just in case

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.

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).
