Hello, just to verify that I to updated to 11.4.1 and was faced with exactly the same WiFi problem. After trying advisory fixes which didn’t work (e.g. clearing network settings) I tried a re-install of the update via iTunes but to no avail. Finally I have now downgraded back to iOS 11.4. On iTunes Which has now fixed the problem.

Let’s hope bugs will be fixed in the next update.

I'm exactly the same.

I don't want to upgrade to HUB3 as it's supposed to be inferior to HUB2, which I have currently, and until now I've had no issues running my iPhone on wifi through it.

As I stated in my earlier post, my MacBook runs perfectly over the same channel as my iPhone, it's just the iPhone which has developed issues since the last iOS update.

It's down to Apple to pull their finger out and fix this, and we shouldn't be expected to change our routers due to their mistake.


If Apple started getting billed for everyones extra data usage due to this wifi issue, I'm sure they'd be a lot quicker to fix it.

Thanks for the feedback, I think before I go through that process and possibly loose everything on my phone I will see what others do to fix the problem. I'm not super technical when comes to backups or restores, I have lost stuff in the past.


I routinely erase my device and restore it and have never lost anything. If you want to make sure everything is backed up, use iTunes.


But my iOS devices back up to iCloud every day pretty much, and I always restore from my last iCloud backup and everything is back in place. However, I use all Apple services, so if your mail, notes, etc. are a different vendor, then iTunes would be the safer way to go.


And again, you have a scenario where you have identical phones and identical iOS versions and they are acting differently. That is a strong argument for making sure your data or apps is not causing your problem.


The process does not take a lot of time (except for the download of purchases which is done by the backup process, so there is nothing you have to do to make it complete that step except be patient). I know it seems like a lot and I felt the same way about going that route until I started doing it for testing purposes. Now, as long as I am sure I have a current backup, I just erase the phone and set it up again.


When you indicate that you lost things when you erased and restored from a backup in the past, can you specify what kinds of things you lost? Because when you restore from a backup, the device should look exactly like it did when the backup was made.


Best,

I have had the same WiFi problems with my IPad Air, iPhone 7plus, and both my apple TVs. I have resettled the settings (even though all Apple devices show connections, even strong connections), I have removed the connection from my iPhone then selected it again only to still not work, I have cleared my cache still no connection. I have tested to see if my WiFi speed is slow, it isn’t and still being detected on all apple devices. Any other suggestions?

I have had the same problem on my iPad pro too. I kept putting off the update for about a week then finally went ahead, it said failed firmware update showing I'm on v11.4.1 I have reset my network setting numerous times. It works for about 10 mins then have to start the process all over again.


Internet is perfectly fine, on Xbox, pc, Samsung s7 phone, iPhone 7, smart tv (netflix) smart hubs....I could go on but they are all connecting with no issues.

This is for Apple to respond. When is Apple rolling out an iOS fix for the router modem problem with 11.4.1. My system is unusable without constantly reconnecting to my Virgin router, about every 5 minutes. Done all the suggestions and not helping. I have an IPad professional only a few days old! Nobody should upgrade to 11.4.1!

The problem seems to be iOS 11.4.1 and Virgin Media Superhub 2.


Virgin Media pretend that the haven ‘t heard about this.

They keep saying reset my iOS devices and Superhub 2.


That does not cure it.

The nuisance is that it might work for 15 minutes then hang. I then change from 2.4 to 5 or vice-versa.

I am on cable , in the UK.

My other iPad on 11.4 works just fine.


Soon we shall have iOS 12 rolled out, and maybe the same problem.


With ios11.4.1 I have tried setting Superhub 2 as a modem and used another route; iOS 11.4,1 works fine with other router, as it does in other people’s houses, with other ISPs.


Is Superhub 2 used in the USA .


I want Apple to try 11.4.1 with Superhub 2 , for a week.


I am fortunate to have an Apple store, eighteen miles away, so I will go and try to make somebody understand.

I too have had issues since updating to iOS 11.4.1! I can’t even turn my ‘Wi-Fi’ button on in ‘Settings’, let alone have my ‘Bluetooth’ sit there with the ‘search’ scroll just go on, and on, and on, and on, etc., etc.!! I just bought the bloody thing last Thursday, so you can geuss how happy I am! 😉 I also have issues waking it up with ‘Touch ID’
