iOS 11.4 WiFi Problems

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 have this same issue since updating to 11.4 on my X. Every time the phone goes to the screen saver, it loses my home wifi network and keeps asking for the password, unless I go in through Preferences>Wifi to reacquire it. Irritating to say the least.

I cannot believe apple has become so inept with their software. Siri, can you fix this? Haha...that was a snide joke.

I experienced similar issues with two of my phones since iOS 11.3 (upgrade to 11.4 did not help). It was definitely not my router as my Kindle works fine. Had tried just about every logical thing to fix this, but the only workaround that is holding up is adding the MAC addresses of all my devices to the router and enabling MAC filtering on the router. My phones have not dropped the wifi signal since I did this a couple of days ago.

I’ve tried that too...worked for about 24 hours, then same problem. I’ve even tried various channels and bandwidths on the router. Everything worked.... for a while. 😟

id like to know where Apple is on this issue.

Just DONT upgrade when offered to upgrade you have to "opt in" to get 11.4 Apple released 11.4.1 to developers to beta test just a few days ago so just wait until 11.4.1 is available to the public in a few weeks. Apple is aware of the problem.

I’m wondering how aware they are. I’ve been reading the 11.4.1 developer blogs and can’t find anything about the WiFi issue, but lots on WiFi message syncing and other things that use WiFi. It could be that the WiFi issue that we‘re experiencing is just a symptom of a new feature that’s in 11.4, but some are reporting the problem with 11.3 also.

Had similar problem with my IOS devices losing then not reconnecting to home wifi. Only solution I have found is to turn router/modem off for 30+ seconds, then not long after it is restarted the IOS will reconnect to wifi. at first this was happening everyday, now just every several days. Hope Apple has some kind of fix in the works.

I’m now thinking of a new router. I notice that when I’m out of the house an on other unsecured networks, everything is fine. I’m now in DC on my daughter’s secured network, and again, just fine. Could my router be going bad and only affecting one device? My iPad? Not likely, but worth a shot buying a new one from Costco. If there’s no difference I can always return it,

It is NOT your router 100% guaranteed and not all Apple Products are affected even in the same household. Save your money and wait for a fix from Apple, 11.4.1 has been sent to developers to beta test or you can go to the Apple Store and have the Genius revert your Apple product to 11.3

We have some devices getting it bad (sons iPad esp) and others (e.g. my iPhone) not bothered - not sure its worth the money to invest in a new router.

Anyone tried issuing a static address or running a sniffer or similar on the network to see any errors?

I agree...I am holding off. Really the situation is very bizarre. Everything I’ve tried, static IP, etc etc, works for a while, then it reverts back to crappy behavior.

as far as reverting to 11.3, Genius can’t do it anymore as Apple isn’t signing off on 11.3 or even 11.4 anymore. sh*t out of luck.

Seems that the Wi-Fi dropping problem does not occur on devices with the A11/M11 processors, but does occur on devices with the A10/M10 processors and older. Let’s hope Apple solves this problem with iOS 11.4.1. Otherwise, leave Apple and switch to Android.

I don't * think * I have iOS 11.x on my Mini, and I have the "No Data Connection" issue too. In Settings > About, for 'Version' it says "10.2 (14C92)". I thought the iPad iOS's ran straight from 9.x to 11.x.

I hate having to fire up slow dinosaur PC and plugging iPad into iTunes just to find out what operating system the thing currently has!

It’s certainly not there fault, but it’s clear that when they have five people sitting at stable with 11.4 issues and they say they’ve never seen connectivity issues, that they’ve been instructed to say so. At the least, it would be nice if they admitted to an issue.
