iPhone 11 freezing/lagging when it has trouble connecting to the wifi

Same issue for me, has been doing it for 5 months now (since I purchased the phone). It took me a couple of months to realise what was happening, but the problem occurs when entering a known WiFi connection area (eg home or work). If your WiFi is enabled in settings, the phone won’t properly connect to the known WiFi and will freeze. If your WiFi is turned off in settings before entering the area, it’s fine.

The phone freezes up and is almost non-responsive (huge lag). I used to hard-restart to overcome the issue but later realised, when I pinned down what the issue was, you can either swipe down to turn WiFi off, or get into your WiFi settings and let your phone properly connect to the known WiFi. Then things are back to normal.

Its hugely annoying though - does anyone have a fix?

Hello everyone, it seems like the “freeze problem” has completely gone when I updated on iOS14

Same problem here!

I've been having this issue since I bought 11. After 3 months experience, I realized that it randomly happens even though WiFi signal is stable. (There are 3-4 APs at home & work) However, whenever my iPhone 11 has touch lags and freezing issue, the WiFi signal is gone from the phone screen and only shown data network sign(LTE), even though the WiFi is still connected. (I can see this in the WiFi setting)

The ways to get out of this lag is to restart (just like hkWhoa mentioned) or turn off the WiFi setting from swipe down menu.

I hope Apple finds out this issue and fix it ASAP.

Glad I’m not the only one. This has been happening since I got my iPhone 11 Pro in November. Freezes/lags 1-2 times a day. Solution is a hard reset or turn off WiFi.

Resetting network settings does resolve the freezing up of the internet connection but the problem returns within a few days. I have an unrelated (ongoing) issue that Apple has been unable to resolve. My only option is to completely erase and restore the phone to factory settings to see if this will fix the issue. Perhaps this will also resolve the internet freeze/drop issue. My theory with some of these "buggy" issues is the proliferation of 3rd party apps that can corrupt the operating system. Considering not everyone is having the same problem, it might have to do with the apps we have on our iPhones.

There are more than one thing to address here. You mention difficulty connecting to wi-fi, then you mention a problem with the iPhone freezing when you are disconnected from wi-fi. Is the freeze only occur when you are disconnected from wi-fi? What kind of troubles are you experiencing when connecting to wi-fi? What version of iOS do you have on the iPhone? What troubleshooting have you tried? How much free space do you have one the iPhone and what is the capacity of the iPhone?

I've had this issue too for the past few months (since before shelter-in-place). It's definitely infuriating. I have eero mesh routers at home. It seems to happen often when I first get home, even though only one router is in range. I usually restart the phone but also sometimes disconnect Wi-Fi.

I'm curious if anyone has tried "Reset Network Settings" and if that's worked. I'm open to it, but would prefer not losing all my saved Wi-Fi passwords if others have tried and haven't had any luck with this.

For those having the issue, have you ever experienced it with more than just one Wi-Fi network (presumably your own at home)? Have any other iOS users in your home experienced the same?

Same problem here (Iphone 11).

Bought it in the US in November, started having issues in December. I got super mad because I was traveling and I had no local SIM card, so had to rely on WIFIs, and whenever I would get back to the hotels at night, my phone completely freezed and I had to struggle for minutes to try shutting it down. The screen was super slow in responding my commands... The reality is, only some WIFIs are causing this problem. There might be a bug in some routers that is causing it? Fun fact is, the Apple store WIFI is one of them. I first showed it to an Apple store assistant, who thought was a screen problem, so I got a new screen. Then after giving proof that it was still happening (through videos taken from my friend's phone), I got a phone replacement. Now I can say this is still happening, so the problem is seriously with the Iphone 11. I can never trust 100% my phone, example: I won't buy the bus tickets on it, as it might stop working if I have to show the ticket to the driver, or save credit cards though Apple Pay. It's ridiculous that this happens on a +1000$ worth phone. Please Apple, do something!

Have had same issue for one year on iPhone X.... and very frustrating. Have sought fixes.... definitely a software bug. It’s lagging on different models of iPhones and always when moving from one room in the house to another ... or building etc.

I have the exact same issue - and pretty similar specs. Seems to be every time I walk into the kitchen (which tends to have bad wifi connectivity). Phone lags and I have to force shut down every time . Absolute nightmare!

Iphone X, same issue :( Struggling with this issue for the past 6 months now.

Didn't happen with my iPhone 7 either.

There was a thread I found that mentioned it may be related to 5ghz and 2.4ghz wifi signals broadcasted under the same wifi name. So I changed each signal to unique names. Still didn't resolve the issue.

I haven't reset my network settings yet because I don't want to lose all my wifi passwords. Plus I haven't seen a single confirmation that it worked despite many people suggesting it.

Same specs as the OP same issue, would just turn off wifi to deal with it, but now my data is burning out way too fast need to find a fix. If the phone sits too long or I change rooms it just locks so. super annoying I've had pretty much every iPhone since 3 and never had one that performed this poorly
