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.

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.

I have now received, and connected a VM Hub 3, through which I am using two iPads , and an iPhone running IOS11.4.1 , along with a Macbook Pro and two Homepods. Since yesterday all are working when on together, with no problems.

I have stopped using a second wifi network , either using Apple Express or Devolo Powerline.


So , fingers crossed, all will be well -until IOS12 is released.

I am not becoming an Apple beta-tester, on one device , for a few months.

I know it’s only been 3 days but how’s it going for you with your iOS device on 11.4.1? Has it held the wireless connection. I have superhub 2 and have had no end of dropouts since I upgraded 2 weeks ago (why did I believe the reviews that said it was safe!?) and massive battery drain that I think is related to the WiFi issue.


i have held off upgrading to SHub 3 due to unkind reviews on the Virgin forums, but it may be a case of the lesser of two evils. So I’d really appreciate if you could update with how it’s going for you.


In the meantime, creating a dedicated hidden Guest SSID as suggested above seems to be working, but it’s only been half an hour. However it’s the first non-interrupted half hour I’ve been connected in the last two weeks.


Thanks in advance
