This discussion may help ios 11.4.1 WiFi issue


From what I’ve read and previously experienced you could try “Forget this Network” under your WiFi Settings then reconnect again, “Resetting Network Settings”, reboot both your iPhone and your Router and last try the other wireless section if dual band.


With respect to the bands, if you usually use 5Ghz then try 2.4Ghz, but also try turning 5Ghz completely off as well, in others words you turn a dual band into a one band unit.


ps. It appears the latest iOS 11.4.1 has introduced this issue for some and will probably require Apple to fix in a future update, so above are just temporary “work around”.

You can install an earlier version, I think 10.3 or so, even if the page gets you a warning. They said, you can install anyway, just because Apple does not recommend you to downgrade (safety), but it´s not dangerous to your phone - they said...

You can’t downgrade if Apple no longer signs that version, and they stopped signing 11.4 a week or so ago, so you definitely can’t downgrade to something much earlier like 10.3.


Note the above applies to the majority of us, but there is a “possible” non-legitimate way which basically intails “hacking” the software/device, with all the risks and legal consequences that brings I will stop here.

I just tried - it didn´t change a thing.

I guess it´s just because you leave your wifi - when it´s lost or weak - and enter your normal internet-account. So you continue without wifi, which might work perfectly well. But for this you don´t need wifi at all.

In my case I am thrown out from my Fritz.Box during telephone calls - it´s not only wifi...

And HTTP does not help at all.

Thanks for the info, unfortunately my colleagues never seem to have this problem even with virgin routers and their android phones, this is not an isolated instance and just seems to be the norm that we accept all of Apples little foibles which have happened on every Iphone I have owned, bot the same fault bit various ones over the years. Time will tell how long this takes.

Agree, and for those like yourself I can only imagine how frustrating it can be, but most haven’t had issues, I’m one of them. The two main problems at the moment appear to be excessive battery consumption and your WiFi connection fault, both appearing with either 11.4 or 11.4.1, but my X and iPad Mini 2 have just kept working as normal and I’m not really sure why.


All I can think of is for any updates I do tend to use iTunes and I don’t have 100’s of Apps on the devices, other than that they are used daily for web, messages, mail, music, podcasts and reading, in fact I probably use more than the iMac now.


It’s really a tuff one to nail down not withstanding the fact my devices couldn’t be more different, the latest X and an almost outdated iPad, go figure.


Still, if Apple would give those affected a way out by allowing a downgrade until they get it together I suppose most would be satisfied, maybe if enough complain they might rethink that strategy.

Posted this in another discussion regarding a call from Apple in the last hour and can confirm they appear to be collecting everything they can regarding the issue, even from those that have for some reason managed to avoid it. Discussed devices I use and method of updating (iTunes), also what impact an upgrade and downgrade could/does have with regards to what’s left on the device that might make things work again.


Obviously they are collecting certain information from different sources, what they find when it’s all put together who knows, anyhow they do seem to be getting more proactive. The other point is it was the forum that’s prompted this course of acion so for those that consider Apple doesn’t listen sometimes (and I may be one of them), it looks like they do, so it’s important as much as possible is communicated in discussions to give them the best chance possible to resolve.

I have run into an issue too, but in my case the wireless mostly works, and then it’s as though I temporarily drop connection, as though the device is hunting for a new network or busy performing some other activity. Some apps like the Apple Store will time out. Others go into a wait state. Pages loading in the browser freeze and sometimes do not restart. I’ve tried hardbooting the device, resetting my router, renewing leases on both my router and the device, and resetting my cable modem. When I reset my router, things seem to get better for a period of time, but then the issue returns. My other devices that I are still at 11.4 do not seem to suffer the same problem, so I am fairly confident it’s the 11.4.1 update, which is why I have not upgraded any other device.

Yes I have exactly the same problem with my iPhone SE since updating to iOS11.4.1

WiFi Router - Virgin Media SuperHub 2 with 2G and 5G Networks

My iPad pro also updated to iOS11.4.1 connects to WiFi without any problems

iPhone SE used to have no problems with WiFi but now disconnects after a while, despite showing three bars on the WiFi signal strength, it is unable to access the internet. If this happens on 2G swap to 5G and its fine for a while, then the same thing happens, swap back to 2G repeat…..

What I have done to try and fix it .....

Rebooted Virgin Router

On iPhone SE Closed down and re-started, Re Booted, Forget Network for both 2G and 5G and then reconnected, Reset Network, Renew Lease and still the problem persists.

Have spoken to Apple support and they suggested taking my phone in to repair, but as so many people have this issue am reluctant to do that.

I've had this fixed for me. Spoke to technical team. they said the wifi network needs resetting by forgetting it and then re joining it.


They told me to go to settings/ general/ reset. The phone starts up. settings/ wi-fi/ touch the "i" in a circle/ forget This Network/ then back to wi-fi/ sign back into your network. That's it, all working again.


Let me know how it goes for you. Mine seems to be working perfectly again.

Yes, sorry I missed that instruction.

The phone starts up. settings/ wi-fi/ touch the "i" in a circle/ forget This Network/ then back to wi-fi/ sign back into your network. That's it, all working again. You don't lose anything from your phone, it takes about 4 mins to get your phone back to working.
