iOS 15.4.1 Wi Fi problem

I start having problem with my network settings too once iOS was updated to 15.4.1. It keeps saying no connection on wifi yet I cannot switch off the wifi function itself, and will have to resort in restarting the phone every single time. My friend has the same exact issues even with different iPhone series but same iOS.

Updated to the new iOS - phone constantly restarting for no reason & my wifi won’t toggle on so currently having to use mobile data. Tried resetting network setting, erasing the phone nothing working

yes funny its intermittent Im checking the speeds during the day and at night never had a problem with the modem before the update. Its happening at certain times. By using the computer and 2 ipads I can check all there speeds. The computer is fine running at good speeds the ipads both slow right down.

Same problem here, Wi-Fi connected no internet other devices work fine, sometime is does it with cellular as well, my solution is next upgrade won't be another iPhone, this problem has been going on for years and it's never fixed, I've had enough, it ruins my daily flow and I’m done

I’m having the same problem but almost worse.

Wifi is unusable on my iPhone 12 mini except when I’m actually on a call (phone, WhatsApp or Voice) and then if my wifi is off, nobody can hear me and I can’t hear them. In this circumstance turning my wifi back on helps.

But if I’m trying to browse websites, forget about it. Nothing loads with wifi.

My iPad Pro is doing just fine on 14.8, returning 52 Mbps on a VPN connection, so there is no excuse.

Yes, I turned VPN off, restarted my phone, and reset all network settings. Nothing is helping.

There are no VPN profiles installed on my iPhone 13. I ended up taking the sim card out of that phone and placing it into my iPhone 11. I just bought the iPhone 13 a month ago and it worked just fine until I installed this useless system update. Now my wi-fi connection that works just fine on my iPhone 11 only works intermittently on the iPhone 13. Reset all network settings, restarted my phone, and nothing was helping to fix the problem. Without access to wi-fi my iPhone 13 is now useless. It was definitely the system update that caused the problem because everything works just fine on my iPhone 11 and on all of my other non-Apple devices.

Can someone who has the intermittent wifi issues perform a speed test when the problems occur on iPhone just so I know if others get the same. Im on wifi 5G and hit 248mbs but browsing etc goes really slow. The speed never really alters much but performance is intermittently ridiculous i.e. its just taken 8 mins to perform a small app update.

Not sure if its related or not but since 15.4.1 i’m getting far more call drops and messages failing to send (ive never previously had a failed message).

Hi yea I also have the same problem with the wifi it’s acting up and it ain’t the wifi itself it’s the software Apple better do something to fix it because it’s driving me insane it’s absurd that my computer works with wifi but my phone is not

Sure, any iOS 15.4.1 user that does not go through the trouble to complain here definitely don’t have any Wifi issues. And you know what, I bet everyone complaining here has only ever connected to 1 Wifi in their whole life and is a VPN user.

When there is a widespread problem you will see literally thousands of posts about it. The record is 13,000 posts and 3 million views about a problem 8 years ago that affected 5 million of the 100 million iPhones sold at that time. Apple users are very vocal, and will raise their voices about any issue that is bothering them.

So the number of posts about a problem is a good indication of how widespread the problem is. If you contact Apple support the problem is logged, and if Apple sees a large number of similar issues they will investigate it. If you just complain here Apple won’t see it, and won’t know if it is a problem or how widespread it is.

I’m having the same Wi-Fi drop issues ever since the latest update. Very annoying. Apple is very slow at correcting issues even when attention to it from its customers is brought up. For what they charge for their products you’d think they would be more timely.

Same exact experience for us. The ONLY wi-fi connection not working is ANY wifi based connection to my iPhone 13 ever since I installed the system update. My iPhone 11 works just fine. I had to remove the SIM card from my iPhone 13 and slip it back into the old iPhone 11. That phone and all wifi connections work perfectly. It is only the iPhone 13 that no longer works with *any*wifi network, whether that network belongs to me or someone else (i.e. my work wifi).

Even though I didn't purchase my iPhone 13 from Best Buy, when I went there a month ago to pay for an expert to install my new screen protector, the tech convinced me to spend $200 and buy a year of support and protection for my iPhone. Which is where I am going next week when I have a day off from work to see if they can help me.

After many many years, Losing trust in this company, glitchy updates, poor user interface (stacks), if it ain’t broke…updated 15.4.1, no previous issues, iPhone 12 says Wi-Fi connected on settings but shows 3g, and also shows connected blue tick but underneath a red , ‘no internet connection ‘ !!!

highly unstable

Apple mist give us the option to downgrad.

Its even worse for me , im not able to provide a stable Hotspot connection to my phone or my Laptop or anyone else. Beside the wifi connection problems.

And all what Apple gives you are tons of Articles about restarting your phone und turn off and on your Router.

Like i said , i would appreciate anther answere than , restart your router, restart your phone etc….

I have an IPhone 13 wich was not Update to either 15.4 or 15.4.1 and it dose not have any problems.

and take to note 200 other ppl are having similar issues.
