Why Does My iPhone Keep Disconnecting From WiFi? Here’s The Truth!

Your iPhone isn’t staying connected to WiFi and you’re not sure why. No matter what you try, your iPhone keeps getting disconnected from the internet. In this article, I’ll show you what to do when your iPhone keeps disconnecting from WiFi!

Turn Wi-Fi Off And Back On

First, trying turning Wi-Fi off and back on. There may be a minor connectivity glitch that keeps disconnecting your iPhone from WiFi.

Go to Settings -> Wi-Fi and tap on the switch at the top of the screen to turn off Wi-Fi. Tap the switch again to turn Wi-Fi back on.

Turn Your iPhone Off And Back On

Turning your iPhone off and back on is another way we can address and attempt to fix a minor software problem. Turning off your iPhone allows all of its programs to shut down and start fresh when you turn your iPhone back on.

To turn off an iPhone 8 or earlier, press and hold the power button until “slide to power off” appears on the screen. If you have an iPhone X or later, simultaneously press and hold the side button and the volume down button until “slide to power off” appears.

Swipe the red power icon from left to right to shut down your iPhone. Wait a few moments, then press and hold the power button (iPhone 8 or earlier) or the side button (iPhone X or newer) until the Apple logo appears on the screen to turn your iPhone back on.

Restart Your WiFi Router

While you’re restarting your iPhone, try restarting your WiFi router too. Sometimes WiFi issues are router-related, not iPhone-related.

To restart your router, simply unplug it from the wall and plug it back in. It’s that simple! Take a look at our other article for more advanced Wi-Fi router troubleshooting steps.

Forget Your WiFi Network & Reconnect

Your iPhone saves information about your WiFi network and how to join to your WiFi network when you connect to it for the first time. When the way your iPhone connects to your WiFi network changes, it can cause a variety of problems.

First, we’ll forget your WiFi network, which completely erases it from your iPhone. When you reconnect your iPhone to your WiFi network, it’ll be as if you’re connecting to it for the very first time!

To forget your WiFi network on your iPhone, go to Settings -> Wi-Fi and tap the information button (look for the blue i) next to the name of your WiFi network. Then, tap Forget This Network.

Now that your Wi-Fi network has been forgotten, go back to Settings -> Wi-Fi and find the name of your network under Choose A Network. Tap on your network’s name, then enter your WiFi password to reconnect to your WiFi network.

Reset Network Settings

Resetting the network settings on your iPhone erases all of its Wi-Fi, Bluetooth, Cellular, and VPN settings and restores them to factory defaults. This means you’ll have to reenter Wi-Fi passwords, reconnect your Bluetooth devices, and set up your VPN again if you have one.

If there’s a software problem with your iPhone’s Wi-Fi settings, resetting network settings will usually fix it. Go to Settings -> General -> Transfer or Reset iPhone -> Reset -> Reset Network Settings. Then, tap Reset Network Settings again to confirm. Your iPhone will shut down, reset its network settings, and turn back on.

DFU Restore Your iPhone

If your iPhone still keeps disconnecting from WiFi, it’s time to put it in DFU mode and restore. A DFU restore erases then reloads all of the code on your iPhone, which is sure to fix any deep software problem. Check out our in-depth DFU restore guide to learn how to put any iPhone into DFU mode!

Exploring Repair Options

It’s time to start exploring repair options if your iPhone is still disconnecting from your WiFi network. It’s possible the antenna that connects your iPhone to WiFi has been damaged, making it difficult for your iPhone to connect and stay connected to WiFi.

Schedule an appointment at your local Apple Store if you plan on having the Genius Bar take a look at it. We also recommend an on-demand repair company called Puls, who can send a certified technician to you in as little as an hour.

You may want to try contacting the manufacturer of your WiFi router if you think there’s an issue with it. Google the name your router’s manufacturer and look for a customer support number to get the ball rolling.

WiFi Connectivity: Fixed!

You’ve fixed the problem with your iPhone and now it’s staying connected to WiFi. Next time your iPhone keeps disconnecting from WiFi, you’ll know how to fix the issue! Leave any other questions or comments you have in the comments section down below.

IPhone 3G не находит Wi-Fi — поделитесь соображениями

13 лет на сайте
пользователь #144001

Копнул темы — вроде, подобного не описывалось. (ну, либо непрально искал)

Имеем iPhone 3G, джейл, прошивка 3.1.3

Не видит ни единой Wi-Fi сети (хотя вокруг их аж 6 шт). Прописывание вручную всех параметров сети — также не приносит результата.

У кого какие будут соображения на эту тему? Поделитесь, пжалста.

1045, первое сброс настроек сети,2-ое перепрошить

Пардон, забыл уточнить — сброс настроек делался неоднократно — те же, только в профиль.

То есть это, всё-таки глюк именно на программном уровне?

16 лет на сайте
пользователь #29575

Нет,это аппаратная проблема. Ищи в гугле,таких оочень много. В оф. сервисном центре в Мокве такие телефоны сразу же меняют на новые.

Нет,это аппаратная проблема. Ищи в гугле,таких оочень много. В оф. сервисном центре в Мокве такие телефоны сразу же меняют на новые.

Вот именно потому я и задал данный вопрос — поскольку гугл на сию траблу отвечает в 99% случаев однозначно — пришёл пушной зверёк блоку Wi-Fi, сие не лечится — только замена.

Вот я и решил поспрашивать — помогла ли кому-нить перепрошивка в подобном случае? или это возымеет эффект не больший, чем укол адреналина безногой лошади?

Same problem here as well!

I finally upgraded from 3.1.3 since reports showed that the user interface speed had increased, only to find this bug. The reason why I upgraded was to make use of an app on free hotel wifi when I go overseas — this just ruined that.

Nov 23, 2010 3:32 AM

I had the same problem after upgrading to iOs 4.2.1 on my iPhone 3GS, i could connect to my Wi-Fi, but no internet access. But i tried this and it worked:

If you’ve verified that your settings are correct and the issue persists, try the following:
— Tap Renew Lease to acquire a new IP address, DNS, and search-domain information from the Wi-Fi network.

(Settings-Wi-Fi- tap the «>» next to your network name and then tap «Renew Lease» )

Hope it works for you as well!

Glad to hear about the successful reinstatement of your Wi-Fi connection. Next time you have an issue you might like to consider the following procedure.

Its always a good idea with any upgrade that you forget the network on the iPhone switch off Wi-Fi then power off the iPhone ‘menu and power button held on together until the Apple logo disappears and the phone is switched off.

Then power off the Router+Modem or Router and Modem. If you have a dynamic IP address on the Internet connection you may have to leave the router off for about 5 minutes so that the IP Lease is released/revoked.

Sometimes it might be necessary to also forget the iPhone with in the Routers settings in other words release the IP lease issued to the iPhone. You can of course make the IP address of the iPhone permanent should you so choose.

Another issue that needs to be check is which channel you have selected the default is usually ‘6’ which you may be sharing with other users. You may be able to improve your Wi-Fi performance by choosing another channel.

There is a piece of software ‘Free or for a Donation’ that will allow you to detect Wi-Fi services in close proximity and what channels they are using. I have no association with this publisher so posting their address in this forum is not an endorsement http://www.vistumbler.net/

Then you power up the Router/Modem check that you have Internet connectivity from a Desktop and then power up the iPhone switch on Wi-Fi and reconnect to the network. Don’t forget that you will need to have a record of the encryption password used by the router usually WPA.
