It’s super frustrating when your iPhone won’t connect to Wi-Fi (especially if you have a monthly cellular data limit instead of an unlimited data plan). Not being able to connect to Wi-Fi stops you from doing things like updating the iOS, downloading large files, and streaming music and video.

You might not be able to connect to Wi-Fi if you’re out of range or there’s interference with the Wi-Fi signal. Make sure you’re close to the wireless router when you’re trying to solve this issue.

This article was written using iOS 12 and iOS 13, but the concepts apply to many earlier versions. On earlier versions, the exact steps described below may be slightly different.

How to Fix iPhone Wi-Fi Problems

In most cases, you can fix an iPhone that won’t connect to a Wi-Fi network after some simple troubleshooting steps. In other cases, more advanced techniques are needed. Check out the many ways you can fix an iPhone that can’t connect to Wi-Fi and get back to high-speed internet access.

Make sure Wi-Fi is on. The first rule of tech support is to confirm the thing you’re trying to fix is turned on. In this case, you may simply need to turn on Wi-Fi on your iPhone. Using Control Center to turn on Wi-Fi is easiest.

A rare issue that comes up is when the iPhone’s Wi-Fi option is grayed out. Luckily, there are several solutions you can try to fix grayed out Wi-Fi.

Check if airplane mode is on. If your iPhone is in Airplane Mode (maybe you accidentally left it that way after a recent trip), your Wi-Fi is disabled.

Check if the Wi-Fi network is password protected. You can tell which networks are password protected because they have lock icons next to them on the Wi-Fi settings screen (go to Settings > Wi-Fi). If it does, you can request a password from the network owner (easy if you’re at a coffee shop, for example) or look for an unlocked network.

You can also try disconnecting and reconnecting from the network. Scroll down to the section called How to Make the iPhone Forget Wi-Fi Networks in this article about Wi-Fi on the iPhone.

Check for iOS updates. If there is an update, install it. That may solve your problem.

Restart your iPhone. Restarting your iPhone often solves its problems. If that doesn’t work, you can force restart your iPhone as a last resort.

Reset iPhone network settings. If one of the Wi-Fi settings is corrupted, it could prevent you from connecting to Wi-Fi. Although this deletes some preferences, sometimes it’s your only option.

Turn off location services. Your iPhone does a lot of helpful things behind the scenes. One of these involves using nearby Wi-Fi networks to improve the accuracy of mapping and location services. This is a nice bonus, but it can be the cause of your iPhone not being able to connect to Wi-Fi.

Restore your iPhone to factory settings. If you’re still unable to connect to Wi-Fi, you may need to take a drastic measure: restoring your iPhone to its factory settings. This deletes everything from the iPhone and returns it to its original, out-of-the-box condition.

When the reset is complete, you’ll have a fresh iPhone. You can then either set it up as a new iPhone or restore from your backup. Restoring from backup is faster, but it could bring back the bug that prevented you from accessing Wi-Fi in the first place.

Contact Apple for tech support. If none of the above fixes work, you might have a hardware problem, which is best diagnosed and repaired by Apple or an authorized Apple service provider. Search Apple’s online support site if you still want to try to fix it yourself. Otherwise, take your iPhone to a local Apple Store; we recommend making an Apple Genius bar appointment.

My iPhone Won’t Connect To Wi-Fi. Here’s The Fix!

Your iPhone won’t connect to Wi-Fi and you don’t know why. Maybe your computer connects, maybe your friend’s iPhone connects, or maybe no devices will connect at all. Maybe your iPhone connects to every Wi-Fi network except for one, or maybe it doesn’t connect to any networks at all.

There are a lot of maybes when it comes to diagnosing and solving this problem, but I’ll help you get to the bottom of it. In this article, I’ll explain why your iPhone won’t connect to Wi-Fi and help you fix the problem, whether it’s with your iPhone or your wireless router.

Meanwhile, At The Genius Bar…

A customer comes in and says their iPhone won’t connect to Wi-Fi. The technician asks the customer to connect to Wi-Fi inside the store, and most of the time, it works. That’s the first step in diagnosing this issue, and the first question you should ask yourself:

“Will my iPhone connect to any Wi-Fi networks, or is it just one network my iPhone won’t connect to?”

If you don’t have another Wi-Fi network to use to test your iPhone, go to Starbucks, your local library, or your friend’s house and try to connect to their Wi-Fi. If your iPhone connects, it’s not a hardware problem – there’s a problem between your iPhone and your wireless router at home.

Note: If your iPhone doesn’t connect to any wireless networks, skip to the section of this article called Delete All The Wi-Fi Networks Stored On Your iPhone. If that doesn’t work, skip to to the section called Diagnosing Hardware Issues. Check out my other article if Wi-Fi is grayed out in Settings!

The Simplest Fix

If you haven’t already, try powering off your iPhone and Wi-Fi router, and turning them back on.

  1. On your iPhone, press and hold the power button until slide to power off appears. Slide across the screen with your finger and wait for your iPhone to power off. It can take 15 seconds or more for your iPhone to power off. Next, hold the power button until you see the Apple logo appears on the screen.
  2. We’ll use a very technical trick to turn your Wi-Fi router off and back on: Pull the power cord out of the wall and plug it back in.

After your router reboots, try reconnecting your iPhone to Wi-Fi. If it works, there was a problem with your wireless router’s built-in software (sometimes called firmware). Few people understand how Wi-Fi networks actually work. All Wi-Fi routers use essentially the same hardware to create wireless networks, but the software built into Wi-Fi routers varies greatly from model to model.

Delete All The Wi-Fi Networks Stored On Your iPhone

Next, try completely resetting your iPhone’s database of Wi-Fi networks. This fixes the issue a lot of the time, and all but eliminates the possibility that a software issue on your iPhone is causing the problem. Go to Settings -> General -> Reset and choose Reset Network Settings.

You’ll have to reconnect to all your Wi-Fi networks and enter their passwords again, so make sure you know the important ones before you begin. Try reconnecting to your wireless router after your iPhone reboots. If it still won’t connect, it’s time to take a look at your wireless router. I’ll show you how to fix it on the next page of this article.


How to fix iPhone WiFi connectivity issues?

As an iPhone user, you may have come across a number of issues relating to the iPhone WiFi and the device’s connectivity to the Internet. Do you experience one or more of the iPhone WiFi connection problems listed below? If yes, make sure to review the tips offered by this troubleshooting article in order to fix the iPhone WiFi not working or not connecting to the Internet.

Common iPhone WiFi problems?

My iPhone WiFi is greyed out

iphone wifi switch dim or greyed out

This is by far the most common iPhone WiFi connectivity problem. The issue is especially widespread on iPhone 4S devices but users having the iPhone 4 and iPhone 5 have also been known to experience the issue.

The reason behind iPhone WiFi switch not working

The exact cause of iPhone WiFi switch being greyed out is not fully known but is well-documented. There are rumors that the issue is related to iOS 6 and the power-management optimizations introduced with this firmware version. iOS 6 is designed to save energy by turning off any hardware elements which are not currently being used on the iPhone. This includes the iPhone’s WiFi, Bluetooth, and baseband (EDGE, 3G) radios.

iphone wifi switch dim and inaccessible

Due to insufficient pre-release testing of iOS 6, WiFi radio chips on iPhone 4S, iPhone 4 – and sometimes – iPhone 5 running this firmware version may overheat. As a consequence to the iOS being able to switch off hardware features on the iPhone, the WiFi chip will automatically be disabled once it overheats. Once the chip is disabled, the WiFi on your iPhone appears as greyed out.

In addition to the WiFi switch being greyed-out, you can also observe the following iPhone behavior:

wifi address on iphone not displayed

“Wi-Fi Address” field under Settings General > About is missing or displaying “N/A”

bluetooth defunc on iphone

When you try to access Bluetooth on the iPhone via Settings > Bluetooth, it is inaccessible and there is a spinning wheel instead of a switch to turn ON or OFF

How to fix a disabled iPhone WiFi switch?

There are at least two ways which have proven to fix the issue. The first method is to use the iPhone’s settings as described below:

disable airplane mode on iphone

Open the Settings app on the iPhone and ensure Airplane Mode is disabled

reset network settings on iphone

Next, navigate to General > Reset and tap “Reset Network Settings”
NOTE: resetting network settings will remove all saved WiFi passwords from the iPhone

press and hold sleep and home buttons to restart iphone

Finally, restart the iPhone. To restart the iPhone press and hold both the Sleep and Home buttons until you see the iPhone screen go black

If this doesn’t help and you still have the iPhone WiFi switch greyed out, make sure to upgrade your iOS to the latest available version. Apple also recommends to use iTunes and restore the iPhone.

NOTE: Upgrading your iOS or restoring the iPhone via iTunes. Be sure to backup your iPhone. To learn more about backing up iOS data, please refer to the following page: Backup iPhone Data.

Will placing the iPhone in a freezer fix the WiFi switch from being greyed out?

There are certain forum threads which deem an alternative solution to fix the WiFi issue.

According to at least one discussion in the Apple community forums, placing the iPhone in a zipper bag and putting it in a freezer is believed to resolve the problem, albeit temporarily.

The reason behind putting the iPhone in a zipper bag and then in your refrigerator’s freezer compartment is that the low temperature will cool down the overheated WiFi radio chip. This will in turn trigger iOS 6 to enable back the iPhone WiFi hardware. We have not tested this method and we do not recommend it. The quick temperature shift between your room and the freezer could potentially damage the iPhone.

If at this point your iPhone WiFi continues to be dim, you must contact Apple directly.

I cannot connect my iPhone to a WiFi network

If your iPhone WiFi radio is operational (e.g. not greyed out), and you cannot connect to a WiFi network, follow the below procedure:

enter password for wifi network on iphone

Ensure that you are trying to connect to the right WiFi network and that you are entering the correct password
NOTE: WiFi network passwords are case-sensitive and could contain numbers and special characters

If this does not solve the issue, reset the iPhone network settings by navigating to General > Reset > Reset Network Settings

My iPhone drops the WiFi connection

First and foremost, make sure that the desired WiFi network signal is strong enough and if not, get closer to the WiFi router and its transmission antenna. Note that the problem might come from the WiFi router or your Internet Service Provider and not from the iPhone. Therefore, be sure that the rest of the devices connected to this network do not experience the same issue.

enter wifi network options on iphone

If signal strength is not a problem and the iPhone still disconnects from the WiFi network, navigate to Settings > WiFi and tap on the arrow next to the problematic WiFi network

renew wifi network lease iphone

Tap “Renew Lease”

iphone forget this network feature

If this does not fix the issue, tap on the “Forget this Network” button instead. If you do so, you will need to reconfigure the desired WiFi network on your iPhone (e.g. enter the WiFi password again)

If you still experience iPhone dropping WiFi connection, you would need to reset the iPhone network settings by tapping Settings > General > Reset > Reset Network Settings.

I don’t have Internet access even after having connected iPhone to WiFi

There is another common WiFi connectivity issue that you might experience on the iPhone. Once you successfully connect to a WiFi network, you do not have access to the Internet. Follow the steps below in order to try and resolve the issue:

additional login window shown upon connecting to wifi network on iphone

If you are trying to connect to a public WiFi network, which requires additional authentication (beyond having entered the correct WiFi password), please see this Apple-provided article: Understanding subscription Wi-Fi networks

reset network settings on iphone

If you are connected to your home WiFi network, check whether the rest of your devices and/or computers are connected to the same WiFi network and whether they have Internet access. If they do, reset the iPhone Network settings by tapping Settings > General > Reset > Reset Network Settings

If none of your devices connected to the same WiFi network have Internet access, turn off your WiFi router and keep the device off for at least 30 seconds. Then turn back on the device and stand-by until the WiFi signal is restored. Turning off the WiFi router will in the vast majority of cases, reset and re-establish the router network settings. However, consult the user manual to learn more about how to reset network settings for your specific router.

If nothing helps, and you continue experiencing iPhone WiFi connectivity issues, be sure to contact Apple directly or schedule a visit to the Genius Bar in the nearest Apple Store. You iPhone might be up for replacement.

Before you replace the iPhone – back up your data

Before you opt for the solution of last resort – having the iPhone replaced – be sure to back up all the needed data in advance.
