IOS 11.4.1 WIFI BUG

Since updating to 11.4.1 my wifi doesn't seem to be working correctly.


I am connected to the wifi but apps like youtube, facebook and whatsapp struggle to connect to the internet but eventually connect after a minute or two.


My old ipad mini first gen is running ios 9 and is working perfectly on the same wifi, so this is clearly an issue with the new ios.


Do you also have this problem?


I put this down to poor quality control, again.

iPhone 6, iOS 11.4.1, 64gb

I would try also to turn off your iphone, then turn off your modem-router, and leave it off for about 10 minutes.

Turn your router back on and wait until it completely ends its configuration.

Then turn on your iphone and connect it to the wifi network. Test it for a while.


If nothing changes, I would check also your router settings (see also if you can configure your device to be connected using 5Ghz (not 2.4).


Check also your router settings again:

Sorry about that.

If your device has the same issue connecting to ALL wifi networks, having already tried some basic troubleshooting steps, I would try to re-install a fresh copy of your iOS, that could be corrupted.

To perform this operation, make a full backup of your iPhone, then restore it to factory settings, and, at the end, set it up as new, following the instructions provided in this support guide:

Restore your iPhone, iPad, or iPod to factory settings - Apple Support


When done, test your device wifi connections for a while, without restoring your data from backup. If it works fine, you can exclude a hardware issue.


Then restore your data from your previously made backup.

Hubby and I have the same issue on iPhone SE (x2) and iPad Air2 (x2). We've done all the resets, forget networks, renaming networks, and hard restarts etc. Been surviving on tapping the wifi button on and off to get a few mins of internet.

I saw something on another thread (iOS 11.4 - Wi-Fi and Bluetooth no longer function) about Bluetooth and tried turning BT off on the iPad. Lo and behold I have working wifi back. Unfortunately, this is useless on the iPhones as we need BT for Apple Watch. It's not a solution, but it's a workaround if you don't need BT on all the time.

Unfortunately this only solved my problem temporarily.


It was working fine on facebook for a few minutes, but when i tried searching on safari it started hanging on the search but turning wifi off via control panel to 4g instantly solved it. Now every app is hanging again.


At a guess, it seems when you switch to another app it generates a new request that forces a dns refresh or to redetect the internet settings.

Okay, my daughters ipad mini updated to the latest ios overnight (something i did not want!)


And now it also has the wifi connection time bug.


Connections to the internet take upto a minute sometimes but on average are 5 seconds.


Constant spinning icon next to the wifi icon.


I have the virgin media superhub 2, surely this is a compatibility issue from the last update?

It seemed okay but it wasn’t, the lag issue was present when a clean install was made.


The issue now happens on both my iPhone and iPad on my network.


My virgin media super hub has be reset multiple times. So I doubt it’s something on both devices that causes the issue.


Both devices worked fine before the update.

I'm sorry you're having this issue too, but at least we aren't alone. I thought i was going crazy and it was just me!


It's not so bad on my phone as i have 10gb data but it's very stressful having my child constantly tell me roblox isn't working, and the only temporary fix is to turn the wifi off and on.


I'm going to make an appointment at my local apple store just to confirm by a tech it's a software issue as it seems the techs on here just tell you to reboot the device.

Please allow me to totally support your suggestion to change your network connection to 5.0 from 2.4. Just bought latest WIFI iPad and connected to 2.4 and worked initially. Within a couple weeks, WIFI connection became unreliable. Switched to 5.0 and iPad was happy again. Two other Apple devices were moved also. I know it could be my Comcast router 2.4. died but the routers 5.0 works just fine. No OS upgrades were done on any device!

Jul 23, 2018 12:54 AM in response to Bill.breslin47

Thank you for the advice but the problem happens with both frequencies.


My devices are connected with full signal but the internet only works for a while on first connection then it’ll stop. Especially if you leave the device alone for a while then try to use it there will be no internet but you’ll still be on the WiFi.


I can control ip cameras connected to my WiFi network but the internet is borked.


Only fix is to disconnect and reconnect to the WiFi.

I have exactly the same issue. My phone keeps dropping out the WiFi so I have to turn it off and on again to work, which is great when you are half way through a transaction etc..and my old iPad has no issues.

Come on Apple...sort it out...again, and again and again and again....feels like I’ve been here before...

Take me home to Kansas....

Classic...whilst I was trying to post a reply my internet had failed and I had to turn it off and on again, again, again

Same problem: everything was working fine on my iPhone 6s until I upgraded to iOS 11.4.1


Now I cannot stay connected to my home WiFi network. The WiFi symbol and settings say I am commected - but no web page or apps will load. If I briefly disconnect then reconnect to WiFi it works - but then 10 mins later I have the same problem. My iPad (which I have not upgraded to 11.4.1) is working absolutely fine, as are all my non-Apple devices.


I tired doing a full backup/restore on my iPhone but it didn’t help. I’ve tried modifying the settings on my router/modem and using Google’s DNS on my iPhone but nothing has helped.


My broadband provider Virgin Media seem to be aware that this is an issue effecting their Superhub 2 modem/router and devices running iOS 11.4.1 - here is a link to their support forum where there are now almost 300 posts of people reporting the exact same problem: https://community.virginmedia.com/t5/Networking-and-WiFi/IPhone-iOS-11-4-1/td-p/ 3771082


I hope that behind the scenes Apple and Virgin Media are working together to come up with either a firmware update for the Superhub 2 or an iOS update that resolves this bug.
