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 have contacted Virgin Media on 3 separate occasions now and they absolutely refuse to spend me a Super Hub 3 for free. They want me to pay £20 which I could do but don’t see why I should as I’m the customer and this isn’t an issue caused by something I’ve done. Also can’t get Apple to talk to me and they haven’t replied to an email sent 4 weeks ago. I’m very disappointed with the attitude from both of these giant companies.

That's very inconsistent of them. I had the same problem as every one else. I booked a technician and he walked in the door clutching a new hub, no discussion about alternative solutions or fixes. Straight swap, NO COST. I do have some sympathy with Virgin since they seem to be picking up the grief and cost for an Apple created problem but they need to treat their customers equally. Maybe the costs of this are just becoming apparent and so they are charging. I suppose £20 is reasonable enough but the whole thing is a mess.

That is disappointing. I contacted Virgin about reducing my monthly fees - we've been customers for over 10 years. When I asked what else they could do for me, the guy offered me a free hub upgrade without any prompting. I think it really depends on who you speak to. Choose the "thinking of leaving virgin" option when you call and you often get better service. Maybe don't mention the reason why you want the upgrade, as they'll quite rightly refuse (this is not their fault) but they may offer you something if you call about another matter and ask what else they can do. btw I can confirm that the hub 3 upgrade has fixed the wifi problem for me, so worth persuing!!

It took me several calls, before a Hub 3 was offered.

I said that I had reset both my iPad and the Superhub2 , and tried everything else that VM technical staff had suggested.

If you are ringing 150, try 151.

Don’t ask for a Hub 3, just say that you have followed all their advice.


By now, of course, VM have a record of your attempts, but I would persist.


As somebody else has suggested, you could ask what notice that you have to give , to cancel your contract. Tell them that you are looking at other providers. In fact, that might be the best approach next. They should then ask why.


In the short term , do you have an old router, or know somebody who could lend you one ? This could be plugged into one of the Modem Mode sockets , at the back to give you an alternative wifi.


I hesitate to say this, but my lady acquaintances ( mostly widows) have often told me that they seem to get badly treated , by companies, because they are women - unless they can act like a Lady Bracknell . Sadly, I think that there is an element of truth in that. Do you have a male relation, who could ring VM. I know this should not be necessary, these days, but the VM helplines are situated outside the UK.


I’ve not typed this in a logical order, sorry.


Good Luck.

I’m surprised more people from the US are not complaining about the same issues. I wake up in the morning and use my phone for about five minutes and it works fine with a strong Wi-Fi signal. After that the signal drops down to one bar in the phone does a lot of buffering. A short time later it drops Wi-Fi completely and often times cannot find any Wi-Fi locations. This is the same thing the phone does every day. Intermittently it will try to connect and might pick up Wi-Fi . Due to this I’m using a lot more data and waiting a lot longer for the phone to respond due to buffering. Also I am experiencing excessive battery drain, it’s so frustrating! My home network is Verizon FiOS with their router I have tried a single band and dual band router with the same issues with both. The iPhone 6 is been the best phone I’ve ever had and I’ll be ****** if I’m gonna be forced to buy a new phone because of a software change that has ruined this phone if that’s the case I’ll be looking at other phones in the future if this doesn’t get resolved.

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

I already went through the wipe clean the phone and reinstall deal did not help at all just a lot of work. I plan to get a new battery soon and to realize the savings before the end of the year. I think I will try to contact Verizon FiOS and see if I can get a new router and see if that helps but the one they offer is a duel band and does not have the range that my older single band router has, perhaps the newer ones are better I will see.

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

I have this too, tested it on several routers. Very annoying bug, I must constantly reset my wifi to get connection. Almost unusable ipad now. Is this they way to force customers to buy new hardware? I guess apple did not make enough profit yet. Oh wait, they bunker the money already and do not know what to do with it. A patch to remove this bug would be very nice!

Seems ok for now for me running ios 12 on sh2, for those still having trouble turn off the 5ghz really is rubbish for distance and make sure in advance settings that the 2.4 ghz is set up for compatibility rather then speed , and just check your bars if only seeing 1-2 bars you will probably have issues , I also tend to pick a channel rather then auto

Sep 21, 2018 1:14 PM in response to yorkshirejoe

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.

Sep 24, 2018 11:42 AM in response to yorkshirejoe

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..
