Same issue here with iPhone 6, I have a very weak or no WiFi connection since the update to 11.4.1 funny thing my wife has the same phone and hers works fine after the update (at least the WiFi). I put them side by side in my basement and her phone finds two strong signals mine fines none.


Since that is the case, then it would be a good idea to determine if your issue is caused by corrupted data or an app or Setting, or if it is possible a hardware issue. To do this, back up your device to iTunes or iCloud, then erase it. When you see the Hello screen, set it up, but when it asks if you want to do it from a backup, choose to set it up as new.


Once it is set up, if you are not already signed in to your Apple account in Settings, do that.


Then do the basement reception check again to see how the two phones compare.


If the problem is gone, then you know it is related to your data or your apps or Settings, so you would need to manually set up the device. Signing into iCloud would have sync'd your iCloud data, and you can download your purchased media via the iTunes and the App Store.


If the problem is not gone, then you should take it into Apple (in the "clean" that you were testing under), and have them look at the device to see if they can determine the cause of the issue.

if you have Virgin Media Superhub 2, and have any old wireless router in a cupboard, plug that into one of the four modem mode sockets and have a second wifi network which should work for any iOS 11.4.1 device.

If you don't happen to have one, see if you can borrow one off a friend or member of the family.

I have an old Airport Express running my second home network, this way, and iOS 11.4.1 iPad runs just fine.

My iPhone and second iPad running iOS 11.4, are still running on VM wifi.( but , of course, will also run on my Airport Express network )


I am fortunate in having run a network cable to my first floor, a few years ago , so I have put my Airport Express upstairs; this has given me a better signal in some areas.

In fact, I shall probably keep this device running , even if Virgin Media , or another iSP comes up with a new wonderful modem/router, since the Airport Express consumes less than 3 watts.


Perhaps, soon, Apple will fix this annoying, frustrating nuisance. Next month, I think that iOS 12 will be forthcoming, but I won't be rushing to put that on my iOS 11.4 devices for a while.


The moral of the story is, don't throw away, or sell an old or spare router.


I am hesitant to ask for a Superhub 3 , from Virgin Media, not least because it is one of the most power-hungry routers on the market, and has quite a few VM-user people saying that it is not as good as SH2.

Here's a fix that seems to be working for me so far.


Go into your super hub router settings (advanced settings) and go to the DHCP configuration section.


Change 'lease time' from 1 day to 10 minutes.

This means your connected devices will renew their connection to the router every 10 minutes.


i.e. it saves you having to do that manually every time the wifi stops responding.


I'd recommend changing it back again if apple manage to fix the problem.

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 can try...


1. Login to SH2


2. Click 'Advanced Settings'

3. Under 'Wireless' Click: 5GHz (or 2GHz) First Guest Wireless Network.

4. Tick the boxes to: 'Enable 5GHz First Guest Wireless Network' and 'Enable SSID Broadcast'

5. Set Security Mode to 'Disable'

6. Set Wireless MAC Filtering to 'Deny All Devices unless in Wireless Filter List'

7. Go down to 'Add Device'

Enter a Name for the device e.g. 'gloveluc's iPhone 6s'

Find your MAC IP address on your iPhone (Settings - General - About - Wi-Fi Address)

It will be 6 pairs of numbers/Letters in the form xx : xx : xx : xx : xx : xx

Enter this into the MAC Address

8. Click 'Add Device' - It should then appear in the Wireless Filter List

9. Click 'Apply'


10. Wait for a couple of minutes while the Router reboots (yes really!)


11. Go to 'Settings - Wi-Fi' on your phone

12. Look for the '5GHz First Guest Wireless Network' in the list of available networks and join it.

(if you can't see it, the Router is still rebooting)


On my iPhone, I have also used the 'Forget this Network' for my former wi-fi connection, to prevent it automatically connecting to the 'old' connection (click the 'i' symbol by the side of your old network to access this).

Still with this problem on iPhone X now on iOS 12 as well.


Something that worked for me was to turn off bluetooth, in general - bluetooth (not in CC). It's very annoying cause i like entering the car and auto play my Apple Music, now i have to always remember to turn it on/off. Also i have an Apple Watch n i cannot be with bluetooth full off.. hope they fix this sometime..

I have the very same issues iOS 11.4.1 WiFi drops turning off wifi and on again is a temporary fix. I have attempted.

1: reset network on iPhone 6 x3 times

2: reset router x3 times

3: connected to routers WiFi 5g and 2g version

4: upgrade routers firmware

5: done a full erase of iPhone and set up as new phone.

6: followed community comments and fixes

7: installed new battery from Apple shop


Nothing has changed my WiFi still drops it’s the iOS programming software not my phone.


The only positive thing that came out of all this after resetting my phone the beta battery health is working again :).


Apple needs to sort it out or they will lose customers to rivals who at least acknowledge their updates have bugs and they are being addressed.

Ps. To upload this post I had to turn WiFi off due to it hanging :(
