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.

This is a general issue with 11.4.1 and Virgin Media Superhub 2. There's plenty about it on the VM Community forum.

Hbhanda posted a temporary solution which does work - I've been using it for a day or so without issues.

I've reproduced it here:


'After talking to a Senior Advisor at Apple...This workaround involves setting up one of the guest networks on the SH2. On the guest network, turn off security (i.e. WPA), add your device under MAC filtering and then hide the SSID if you wish once the iPhone is connected. I have been using my iPhone 6s with iOS 11.4.1 which had the WI-Fi connection/disconnection issue with the SH2 for a few hours on this guest network and it appears to work.'

The problem appears to be with encryption. The solution above is a safe option, as it still protects your network. Not ideal, but will work until the next update.

Hope this helps....

IPhone 6 Plus

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.

Had issue a while back that my Network kept going down, in the end it was an problem with the 5Ghz wireless element, it wasn’t good enough to just switch over to 2.4Ghz (more than likely due to interference between the two bands), I had to also turn off the 5Ghz section entirely under the router settings.


Another area that may cause issue is if the 2.4Ghz and 5Ghz bands have the same name, it’s usually a good idea to make them different, for example Netgear1234-2g and Netgear1234-5g.


Worth noting is when I switched to a router provided by TalkTalk I didn’t experience the same loss of signal issue, even leaving to two wireless sections enabled, so my conclusion was it appeared specific to that particular bit of Netgear equipment.

Hi. After talking to a Senior Advisor at Apple today there is another potential temporary workaround which people could try with the Virgin Media SuperHub 2. This workaround involves setting up one of the guest networks on the Virgin Media SH2. On the guest network, turn off security (i.e. WPA), add your device under MAC filtering and then hide the SSID if you wish once the iPhone is connected. I have been using my iPhone 6s with iOS 11.4.1 which had the WI-Fi connection/disconnection issue with the SH2 for a few hours on this guest network and it appears to work. I will test further. This gives us something whilst Apple are investigating the issue and will hopefully provide a fix in a future update. Apple did say that would contact me if they required further diagnostic information from my device/sh2 and that they had already collected some from others. HTH

I have just read the threads and the issue seemed to me to be tied to the dual band router so I tried to connect to a Tp link expander unit instead of directly to the router. Guess what it worked as a temporary solution. I tried both iPhone6s and ipads which worked fine.

This can only be a temporary solution but it does work (around £15 for the expander) and overcomes the problems with wifi dropping out until Apple fix it properly

Hi all,

The problem is a conflict with dual band wifi hubs. I have a simple fix for Virgin Media users. On the bottom of your hub is an IP address, type that into your browser. It'll then ask for the password which is also on the bottom of your hub.

You can then click on WiFi Wireless Settings and simple disable one of the wireless bands. Your hub is now a single band - this fixed the problem for me!!

Hi. I felt exactly as you did. I did a clean install of iOS 11.4.1 (as I’m wiped my phone and installed it as new just in case a conflict was making it worse). I replaced the battery which apparently had done 700 charge cycles. If you’ve not replaced your battery yet you should right now as Apple is doing a battery replacement for $25 or £25 instead of the usual 75. That already made a huge difference to my battery life. The WiFi issue (which was adding to the battery drain problem) seemed to be being caused by my older dual band router. When I set up a single band guest network it was fine, and now that I’ve upgraded my router everything is good.


The WiFi issue had me at the end of my rope. It was mostly fine on other people’s networks or public ones, but kept dropping at home.


So based on my recent issues I’d start with replacing the battery and go from there. If your router is several years old then that’s next.


Best of luck

Aug 30, 2018 2:23 PM in response to helpme705

My new one is also dual band, but instead of showing two individual ssids is shows one and automatically switches to the better connection. The phone seems to cope with this much better than when it had two ‘duelling’ bands (sorry bad pun)


Our provider did say that it was a known issue with Apple products and the older router. We actually have had issues a couple times a week where it would kick the device off then we would get locked out of one or the other band when it decided it didn’t like the phone at that moment and would have to reboot the router. That seemed to be a million times magnified on this phone with the update and constantly getting dropped connections. We’ve not had that old issue with any of our Apple devices since the new router


What worked for me in the meantime until the new one arrived was setting up a guest network with a few specific settings that only allowed my phone to access it. There’s instructions above as to how to do this on our Superhub, but I’m sure you could transfer them to whatever unit you have. It worked for the 4 days between ordering and receiving the new router. The only thing I did differently to the instructions was after I connected to it I hid the SSID so no one else could see it as an extra precaution

Waited for a month with no wifi until 12 came out and no help. Finally tried hard coding my IP and DNS settings (tap i in circle next to wifi name) and was able to finally connect to my home wifi. Note, I did have to use Google's DNS (8.8.8.8), it would not work using my home network DNS.


I did have to forget the other networks I did not hard code the IP for because my phone would try to connect to them first with no luck. I picked an address at the high end of my range. Have iPad and iPhone X at older iOS versions working fine via DHCP. Just one iPhone X was upgraded to 11.4.1 (then 12) that had issues connecting to wifi. So an option might be hard coding your IP and DNS settings.

It Is not the hub's virgin or otherwise in my humble opinion. if you have other devices working fine with your wifi (like computer) then your Wifi is ok. What you can do (what I did!) to be "sure" it is your iPhone or your iPad etc ... is to disable the auto-join feature in your iPhone or iPad devices: Setings>wifi> "your wifi" connection> click on the little i and disable auto-Joint. Go back to your home screen and live the iPhone or ipad for a while (at least 15 minutes). If afterwards you pickup the iPhone or iPad and you are disconnected then you will know that it is your iOS that has dropped the Wifi (check on your computer if the wifi is still working just to be on the safe side). Re enable the auto-joint again.


Apple is aware of this discussion topic and they are investigating it. They called me yesterday (and some other people) to run some analytic while reproducing the issue. so patience. It seems from the postings that old iOS models iPhone 6 iPads 2 are mostly concerned. We have to wait until apple zeroed in on the problem.


There is of course always a chance that our individual wifi setups might be the problem but even in that case we need to be patient for apple to do their work so that we can proceed by elimination what might cause the problems.


In the mean time those reading this post can you provide/post your iOS device model having the problem with 11.4.1 by replying to my post?

Finally got the chance to speak to VM. Spoke to the support rep and explained him the issue, he said they've heard no such reports about Super Hub 2 to be the issue with iPhone devices and blatantly told me that he can not replace my Super Hub 2 and after insisting that i speak to someone (Manager) who can make that decision he put me on hold and after a min came back saying "We've just received an update 30 min ago and the manager has agreed to replace the Super Hub 2 with Super Hub 3". I then asked if the devs are working on a firmware update he said "I'm not sure at the moment but we've been told to simply replace the SH2 to SH3".

I'll be getting mine in 2-3 days.

It looks as if this issue may be an interaction between the current build of iOS and some routers. If yours has multiple channels you could try turning some of them off so your device is less likely to try to hunt between them. A few Virgin subscribers seem to have managed to persuade Virgin to supply updated routers. Apple will hopefully include a patch for this problem in the next release of iOS.
