互联网(Internet)已经成为我们生活中不可或缺的一部分，当我们没有互联网连接时，我们会感到无能为力。虽然移动数据价格越来越便宜，4G出现后网速也有明显提升，但Wi-Fi仍然是浏览互联网的首选。
但是有时，尽管安装了Wi-Fi路由器，我们还是被禁止连接到它。这是因为Android智能手机中的常见故障导致Wi-Fi无法打开。这是一个非常令人沮丧的错误，需要尽快消除或修复。由于这个原因，我们将讨论这个问题并提供简单的修复程序，使您能够解决这个问题。
Wi-Fi 无法打开的原因是什么？(What are the reasons behind Wi-Fi not turning on?)
有几个原因可能会导致此问题。最可能的原因是您设备上的可用内存 ( RAM ) 非常低。如果可用RAM(RAM)少于 45 MB ，则Wi-Fi将不会打开。另一个可能阻止Wi-Fi(Wi-Fi)正常打开的最常见原因是您设备的节电模式已打开。省电(Battery)模式通常会阻止您通过Wi-Fi连接到互联网，因为它会消耗大量电量。
这也可能是由于硬件相关错误。长时间使用后，智能手机的某些组件开始出现故障。您设备的Wi-Fi可能已损坏。但是，如果您很幸运并且问题与软件问题有关，则可以使用我们将在下一节中提供的简单解决方案进行修复。
如何修复 Wi-Fi 无法打开 Android 手机(How to Fix Wi-Fi Won’t Turn on Android Phone)
1.重新启动您的设备(1. Reboot your Device)
无论(Irrespective)您面临什么问题，简单的重启都可以解决问题(reboot can fix the problem)。由于这个原因，我们将使用古老的“您是否尝试过将其关闭然后再打开”来开始我们的解决方案列表。它可能看起来模糊且毫无意义，但如果您还没有尝试过，我们强烈建议您尝试一次。按住电源按钮(Press and hold the power button)直到屏幕上弹出电源菜单，然后点击Restart/Reboot button。设备启动后，尝试从“快速(Quick)设置”菜单打开 Wi-Fi ，看看它是否有效。如果不是，则继续下一个解决方案。
2.禁用电池保护程序(2. Disable Battery Saver)
如前所述，电池(Battey)保护程序可能是导致Wi-Fi无法正常打开的原因。尽管省电模式是一项非常有用的功能，可以让您在紧急情况下延长电池寿命，但始终保持开启状态并不是一个好主意。这背后的原因很简单；电池通过限制设备的某些功能来节省电量。它会关闭在后台运行的应用程序、降低亮度、禁用Wi-Fi等。因此，如果您的设备上有足够的电池，请禁用节电模式，这可能会解决此问题。请按照以下步骤查看如何：
1.首先，在您的设备上打开设置。(Settings)
2. 现在点击电池(Battery)选项。
3. 在这里，确保“省电模式”(“Power saving mode”)或“(“Battery Saver”)省电模式”旁边的拨动开关被禁用。
4.之后，尝试打开你的Wi-Fi，看看你是否能够修复Wi-Fi不会打开Android手机的问题。 (fix Wi-Fi won’t turn on Android Phone issue. )
3.确保飞行模式已关闭(3. Make sure that the Airplane mode is Turned off)
这可能看起来很傻，但有时我们不小心打开了飞行(Airplane)模式，甚至没有意识到这一点。当我们的设备处于飞行模式时，整个网络接收中心都被禁用——Wi -Fi(Wi-Fi)和移动数据都不起作用。因此，如果您无法在设备上打开Wi-Fi，请确保禁用飞行模式。(Airplane mode is disabled.) 从通知面板向下拖动(Drag)，这将打开快速(Quick)设置菜单。在这里，请确保关闭飞行模式。(Airplane)
4. 重启手机(4. Power Cycle the Phone)
重启设备意味着将手机与电源(Power)完全断开。如果您的设备有可拆卸电池，则您可以在关闭设备后取出电池。现在将电池放在一边至少 5-10 分钟，然后再将其放回设备中。
但是，如果您没有可拆卸电池，则可以使用另一种方法来重启设备，即长按电源按钮 15-20 秒。手机关闭后，至少保持 5 分钟，然后再将其关闭。重启(Power)设备是解决各种智能手机相关问题的有效方法。试试看，它可能会修复您的Android手机上的Wi-Fi无法正常打开的问题。
5.更新路由器固件(5. Update the Router Firmware)
如果上述方法均无效，则问题可能与您的路由器有关。您需要确保路由器的固件已更新，否则可能会导致 Wi-Fi 身份验证或连接问题。请按照以下步骤查看如何：
1.首先，打开浏览器，输入路由器网站的IP地址(IP address of your router’s website)。
2. 您可以在路由器背面找到此 IP 地址以及默认的用户名和密码。
3. 到达登录页面后，使用用户名和密码登录(username and password)。不是在大多数情况下，默认情况下用户名和密码都是“admin”。
4. 如果这不起作用，那么您也可以联系您的网络服务提供商，向他们索取登录凭据。
5. 登录路由器固件后，转到高级选项卡(Advanced tab)。
6. 在这里，单击固件升级(Firmware upgrade)选项。
7. 现在，只需按照屏幕上的说明进行操作，您的路由器固件就会升级。
6. 释放内存(6. Free up RAM)
如前所述，如果设备上的可用内存小于 45 MB ，则Wi-Fi将不会打开。(Wi-Fi)导致手机内存不足的原因有很多。即使您什么都不做或屏幕空闲时，后台(Background)进程、更新、未关闭的应用程序等也会继续使用RAM 。释放内存的唯一方法是关闭在后台运行的应用程序，这意味着从“最近的(Recent)应用程序”部分中删除应用程序。除此之外，您还可以使用内存增强应用程序定期关闭后台进程以释放RAM。很多安卓(Android)智能手机预装了内存加速器应用程序，而其他智能手机可以从Play 商店轻松下载(Play Store)CCleaner等第三方应用程序。下面给出了释放RAM(RAM)的分步指南。
1.首先，来到主屏幕并打开最近的(Recent)应用程序部分。根据OEM的不同，它可以通过“最近(Recent)使用的应用程序”按钮，也可以通过某种手势，例如从屏幕左下角向上滑动。
2.现在通过向上或向下滑动缩略图或直接单击垃圾桶图标来清除所有应用程序。
3. 之后，安装(install)第三方RAM Booster 应用程序，如CCleaner。
4. 现在打开应用程序并按照屏幕上的说明为应用程序提供所需的所有访问(Access) 权限(Permissions)。
5. 使用该应用程序扫描您的设备中的垃圾文件、未使用的应用程序、重复文件等并消除它们。
6.您还可以在屏幕上找到一键式按钮来提升(Boost)内存、释放空间、清洁提示等。
7. 使用此应用程序完成清理后，尝试打开您的 Wi-Fi 并查看它是否正常工作。
7. 卸载恶意第三方应用程序(7. Uninstall Malicious Third-Party Apps)
Wi-Fi 无法打开(Wi-Fi not turning on)的原因可能是最近安装的一些第三方应用程序是恶意软件。有时，人们下载应用程序时并没有意识到这些应用程序中含有会损害手机的病毒和木马程序。由于这个原因，我们始终建议您仅从Google Play Store等受信任的网站下载应用程序。
确保安全的最简单方法是在安全(Safe)模式下重新启动设备。在安全模式下，所有第三方应用程序都被禁用，只有系统应用程序可以运行。在安全模式下，只允许运行内置的默认系统应用程序。如果Wi-Fi通常在安全模式下打开，则表示问题是由您在手机上安装的某些第三方应用程序引起的。要在安全(Safe)模式下重新启动设备，请按照以下简单步骤操作。
1. 按住电源按钮(power button)，直到您在屏幕上看到电源菜单。
2. 现在继续按电源按钮，直到看到一个弹出窗口，要求您以安全模式重新启动(reboot in safe mode)。
3. 点击确定(Ok)，设备将重启并以安全模式重启。
4. 现在，根据您的OEM，此方法可能与您的手机略有不同。如果上述步骤不起作用，我们将建议您谷歌您的设备名称并寻找在安全模式下重启的步骤。
5. 设备启动后，检查Wi-Fi 是否开启。(Wi-Fi is turning on or not.)
6.如果是，则确认Wi-Fi无法打开的原因是某些第三方应用程序。
7.卸载任何最近下载的应用程序，或者更好的解决方案是下载在此问题开始发生时安装的所有应用程序。
8. 删除所有应用程序后，重新启动进入正常模式。简单的重新启动将允许您禁用安全模式。
9.现在，尝试打开Wi-Fi，看看你是否能够修复Wi-Fi不会打开Android手机的问题。(fix Wi-Fi won’t turn on Android phone issue.)
8. 执行出厂重置(8. Perform a Factory Reset)
最后，如果这些方法都不起作用，那么是时候拿出大炮了。恢复出厂设置以擦除设备上的所有内容，这将与您第一次打开设备时一样。它将恢复到开箱即用的状态。选择恢复出厂设置会删除您手机中的所有应用程序、数据和其他数据，例如照片、视频和音乐。由于这个原因，您应该在恢复出厂设置之前创建一个备份。当您尝试将手机恢复出厂设置时，大多数手机都会提示您备份数据。您可以使用内置工具进行备份或手动进行；这是你的选择。
1. 转到手机的设置，然后点击(Settings)系统(System)选项卡。
2. 现在，如果您尚未备份数据，请单击备份您的数据选项(Backup your data option)将您的数据保存在 Google Drive 上。
3. 之后，单击重置选项卡(Reset tab)。
4. 现在，单击重置电话(Reset Phone)选项。
5. 这需要一些时间。手机重新启动后，请尝试再次打开 Wi-Fi，看看它是否正常工作。

8 Ways to Fix Wi-Fi Won’t Turn on Android Phone
The Intеrnet has become an integral part of our lives, and we feel powerless when we do not have an internet connection. Although mobile data is becoming cheaper day by day and its speed haѕ also improved signіfiсantly аfter the advent оf 4G, Wi-Fi remains the first choice for browsing the internet.
However sometimes, despite having a Wi-Fi router installed, we are barred from connecting to it. This is because of a common glitch in Android smartphones where the Wi-Fi won’t turn on. This is a pretty frustrating bug that needs to be eliminated or fixed as soon as possible. Due to this reason, we are going to discuss this issue and provide easy fixes that can enable you to solve this problem.
What are the reasons behind Wi-Fi not turning on?
Several reasons could cause this problem. The most likely reason is that the available memory (RAM) on your device is very low. If less than 45 MB of RAM is free, then the Wi-Fi will not turn on. The other most common reason that can prevent the Wi-Fi from turning on normally is that your device’s battery saver is on. Battery saver mode usually prevents you from connecting to the internet via Wi-Fi as it consumes a lot of power.
It could also be due to a hardware related error. After prolonged periods of use, certain components of your smartphone start failing. The Wi-Fi of your device may have been damaged. However, if you are lucky and the problem is related to a software issue, it can be fixed using the simple solutions we will provide in the next section.
How to Fix Wi-Fi Won’t Turn on Android Phone
1. Reboot your Device
Irrespective of the problem that you are facing, a simple reboot can fix the problem. Due to this reason, we are going to start our list of solutions with the good old “Have you tried turning it off and on again”. It might seem vague and pointless, but we will strongly advise you to try it once if you haven’t done it already. Press and hold the power button until the power menu pops up on the screen, and then tap on the Restart/Reboot button. When the device starts up, try turning on your Wi-Fi from the Quick settings menu, and see if it works. If not, then proceed to the next solution.
2. Disable Battery Saver
As mentioned earlier, Battey saver could be responsible for Wi-Fi not turning on normally. Although battery saver is a very useful feature that allows you to extend the battery life in emergencies, keeping it on at all times is not a great idea. The reason behind this is simple; the battery saves conserves power by limiting certain functionalities of the device. It closes apps running in the background, reduces brightness, disables the Wi-Fi, etc. Thus, if you have enough battery on your device, disable battery saver, that might fix this problem. Follow the steps given below to see how:
1. Firstly, open Settings on your device.
2. Now tap on the Battery option.
3. Here, make sure that the toggle switch next to “Power saving mode” or “Battery Saver” is disabled.
4. After that, try turning on your Wi-Fi and see if you’re able to fix Wi-Fi won’t turn on Android Phone issue.
3. Make sure that the Airplane mode is Turned off
It might seem silly, but sometimes we accidentally turn on the Airplane mode and don’t even realize it. When our device is on airplane mode the entire network reception center is disabled—neither Wi-Fi nor mobile data work. Therefore, if you are unable to turn on Wi-Fi on your device, make sure that the Airplane mode is disabled. Drag down from the notification panel, and this will open the Quick settings menu. Here, make sure that the Airplane mode is switched off.
4. Power Cycle the Phone
Power cycling your device means completely disconnecting your phone from the power source. If your device has a removable battery, then you can remove the battery after turning off your device. Now keep the battery aside for at least 5-10 minutes before putting it back in your device.
However, if you do not have a removable battery, then there is an alternate way to power cycle your device, which involves long pressing the power button for 15-20 seconds. Once the mobile is switched off, leave it like that for at least 5 minutes before turning it back. Power cycling your device is an effective way to solve various smartphone-related issues. Try it, and it might fix the Wi-Fi not turning on normally on your Android phone.
5. Update the Router Firmware
If none of the above methods work, the problem might be associated with your router. You need to make sure that the router’s firmware is updated, or it might cause Wi-Fi authentication or connection problems. Follow the steps given below to see how:
1. Firstly, open your browser and type in the IP address of your router’s website.
2. You can find this IP address printed at the back of the router along with the default username and password.
3. Once you reach the login page, sign with the username and password. Not in most cases, both the username and password are ‘admin’ by default.
4. If that doesn’t work, then you can also contact your network service provider ask them for the login credentials.
5. Once you have logged in to your router’s firmware, go to the Advanced tab.
6. Here, click on the Firmware upgrade option.
7. Now, simply follow the on-screen instructions, and your router’s firmware will be upgraded.
6. Free up RAM
As mentioned earlier, Wi-Fi won’t turn on if the available memory on your device is less than 45 MB. A lot of factors are responsible for causing your phone to run out of memory. Background processes, updates, unclosed apps, etc. continue to use the RAM even when you are not doing anything or when the screen is idle. The only way to free up memory is to close apps running in the background, and that means removing apps from the Recent apps section. In addition to that, you can also use a memory booster app that periodically shuts down the background process to free up RAM. A lot of Android smartphones have a pre-installed memory booster app, while others can easily download third-party apps like CCleaner from the Play Store. Given below is a step-wise guide to free up the RAM.
1. Firstly, come to the home screen and open the Recent apps section. Depending on the OEM, it could either be through the Recent apps button or via some gesture like swiping up from the bottom left-hand side of the screen.
2. Now clear all the apps by either swiping their thumbnails up or down or by directly clicking on the trash can icon.
3. After that, install a third-party RAM booster app like CCleaner.
4. Now open the app and follow the on-screen instructions to give the app all the Access Permissions that it needs.
5. Use the app to scan your device for junk files, unused apps, duplicate files, etc. and eliminate them.
6. You can also find one-tap buttons on the screen to Boost memory, free up space, cleaning tips, etc.
7. Once you have completed a cleanup using this app, try switching on your Wi-Fi and see if it works properly or not.
7. Uninstall Malicious Third-Party Apps
It is possible that the reason behind Wi-Fi not turning on is some recently installed third-party app that is malware. Sometimes people download apps without realizing that they are laced with viruses and trojans that harm their phones. Due to this reason, it is always advised to download apps only from trusted sites like Google Play Store.
The easiest way to make sure is by rebooting the device in Safe mode. In safe mode, all third-party apps are disabled, and only system apps are functional. In safe mode, only the in-built default system apps are allowed to run. If the Wi-Fi turns on generally in safe mode, then it means that the problem is being caused by some third-party app that you have installed on your phone. To restart the device in Safe mode, follow these simple steps.
1. Press and hold the power button until you see the power menu on your screen.
2. Now continue pressing the power button until you see a pop-up asking you to reboot in safe mode.
3. Click on Ok, and the device will reboot and restart in safe mode.
4. Now, depending on your OEM, this method might be slightly different for your phone. If the steps mentioned above do not work, we will suggest you Google your device’s name and look for steps to reboot in Safe mode.
5. Once the device starts, check whether the Wi-Fi is turning on or not.
6. If it does, then it confirmed that the reason behind Wi-Fi not turning on is some third-party app.
7. Uninstall any recently downloaded app, or an even better solution would be to download all the app that was installed around the time when this problem started to occur.
8. Once all the apps are removed, reboot into normal mode. A simple restart will allow you to disable Safe mode.
9. Now, try switching on the Wi-Fi and see if you’re able to fix Wi-Fi won’t turn on Android phone issue.
8. Perform a Factory Reset
Finally, if none of the methods work then, it is time to bring out the big guns. A factory reset to wipe everything from your device, and it will be just the way it was when you switched it on for the first time. It will return to its out of the box condition. Opting for a factory reset would delete all your apps, data, and other data like photos, videos, and music from your phone. Due to this reason, you should create a backup before going for a factory reset. Most phones prompt you to backup your data when you try to factory reset your phone. You can use the in-built tool for backing up or do it manually; the choice is yours.
1. Go to the Settings of your phone then tap on the System tab.
2. Now, if you haven’t already backed up your data, click on the Backup your data option to save your data on Google Drive.
3. After that, click on the Reset tab.
4. Now, click on the Reset Phone option.
5. This will take some time. Once the phone restarts again, try switching on your Wi-Fi again and see if it works properly or not.
