如果您家中的 Wi-Fi 路由器开始出现故障，或者您前往无法访问互联网的地区，则使用您的Android手机设置移动热点可以帮助您快速让其他设备恢复在线。我们将向您展示如何做到这一点。
您的Android手机允许您通过将自身广播为个人热点来与其他设备共享蜂窝数据。当您无法访问常规Wi-Fi时，这是一种快速简便的访问互联网的方法。
但是，将您的Android设备设置为移动热点会消耗电池寿命，因此您可能希望谨慎使用它。对于较长的会话，最好探索不太传统的方法，例如USB和蓝牙(Bluetooth)网络共享。
根据您的蜂窝网络计划，某些运营商可能会禁止您共享移动数据或要求您为 Tether 设备支付额外费用。如果您有疑问，请在开始之前确认。
注意：以下教程演示了通过热点、USB和蓝牙(Bluetooth)在运行Android 12的(Android 12)Google Pixel上共享您的 Android 互联网连接。根据您的设备和系统软件版本，以下步骤可能会略有不同。
在 Android 上激活移动热点
首次在Android手机上与其他设备共享互联网时，您必须查看设备的“ Wi-Fi热点”设置。这允许您更改默认热点名称、调整安全级别并记下Wi-Fi密码。您还可以使用一些设置来延长电池寿命并扩展兼容性。要做到这一点：
1.通过您的Android设备的主屏幕找到(Locate)并打开设置应用程序。(Settings)或者，打开应用程序抽屉并搜索它。
2.点击网络(Tap Network)和互联网 >热点(Hotspot)和网络共享以访问您的移动热点和网络共享设置页面。然后，选择Wi-Fi热点。
3. 调整以下设置，打开使用Wi-Fi热点旁边的开关：
- 热点(Hotspot)名称：为您的 Android 热点功能设置一个可识别的网络名称。(Set)如果不是，它将使用默认设备名称。
- 安全性：选择可用的 Wi-Fi 安全协议(available Wi-Fi security protocol)，例如WPA3 -Personal、WPA2/WPA3 -Personal 和WPA2-Personal。WPA3具有更好的安全性，但可能与旧设备不兼容。如果遇到连接问题，请坚持(Stick)使用默认WPA2/WPA3设置或选择WPA2 。
- 热点(Hotspot)密码：记(Note)下默认的热点密码。这是一个随机的字母数字字符串，因此请随时更改它。但是，不要使用容易猜到的密码(don’t use an easy-to-guess password)。
- 自动关闭(Turn)热点：让您的Android在未连接设备时自动关闭移动热点以节省电池寿命。
- 扩展兼容性：允许(Allows)旧设备检测您的Android热点并将其用作 Wi-Fi 连接。但是，这可能会导致电池更快耗尽。
您现在可以从另一台设备连接到Android手机的热点。该过程类似于加入典型的 Wi-Fi 网络。在您的 PC 或Mac上，选择系统托盘或菜单栏上的 Wi-Fi 图标，选择移动热点名称，然后输入其密码。
也可以通过这种方式连接 iOS 或 iPadOS 设备——只需前往Wi-Fi选择屏幕即可加入。您也可以点击“ Wi-Fi热点”界面中的(Wi-Fi)二维码(QR Code)按钮，用iPhone或iPad相机扫描，无需输入密码，即刻加入热点。请改用附近共享(Nearby Sharing)以允许其他Android移动设备进入热点网络。
接下来，您可以通过“快速设置”(Quick Settings)窗格打开和关闭Android设备的热点。只需(Just)从屏幕顶部向下滑动即可打开它（您可能需要向下滑动两次或向侧面滑动才能显示所有设置）。然后，点击热点(Hotspot)图标以切换功能或长按它以访问“ Wi-Fi热点”设置屏幕。
同样(Again)，您的Android热点使用大量电量来保持活跃。如果您尚未将设备配置为在未连接设备时自动关闭热点，请不要忘记这样做并避免电池耗尽。
在 Android 上激活 USB 网络共享
如果您手头有USB数据线，您可以通过USB将您的(USB)Android连接到台式机或笔记本电脑设备，并以这种方式共享您的蜂窝数据计划。这样可以加快互联网速度并阻止手机电池耗尽。但是，USB网络共享会阻止您连接其他设备，并且可能会消耗笔记本电脑的电池寿命。
1.在您的Android设备上打开(Android)设置(Settings)应用程序，然后点击网络(Network)和互联网 >热点(Hotspot)和网络共享。
2. 打开USB(USB) tethering旁边的开关。
3. 将您的Android连接到您的 PC 或Mac并断开与其他无线网络的连接（或禁用Wi-Fi模块）。它应该通过USB(USB)自动开始使用移动数据。
与移动热点不同，当您不主动使用
USB网络共享时，您无需关闭它。
(Activate Bluetooth Tethering)在Android上(Android)激活蓝牙网络共享
还可以通过蓝牙将互联网共享到(Bluetooth)Android手机上的台式机或笔记本电脑设备。它会导致互联网速度变慢，并且设置和使用有些复杂。但是，与使用热点网络相比，它大大减少了电池消耗。
1. 打开安卓设备上的(Android)设置(Settings)应用，点击网络(Network)和互联网 >热点和网络共享，然后打开(Hotspot)蓝牙(Bluetooth)网络共享旁边的开关。
2. 将您的Android(Android)手机与您的台式机或笔记本电脑配对。在Microsoft Windows中，您可以打开开始(Start)菜单并选择Settings > Bluetooth和设备 >添加(Add)设备。在Mac上，打开Apple菜单并转到System Preferences > Bluetooth。确保(Make)在配对过程中将您的Android置于发现模式（只需转到Settings > Connected的设备）。
3. 配置您的 PC 或Mac以开始使用蓝牙(Bluetooth)。在Windows中，右键单击Windows任务栏上的(Windows)蓝牙(Bluetooth)图标并选择加入个人局域网(Join Personal Area Network)。或者，打开控制面板(open the Control Panel)并选择硬件(Hardware)和Sound >设备(Devices)和打印机(Printers)。接下来(Next)，突出显示您的Android并选择连接(Connect)到 >接入点(Access Point)。
在Mac上，转到System Preferences > Network，选择加(Plus)号图标，然后添加Bluetooth PAN。
注意：在撰写本文时，Apple已取消在运行 macOS 12 Monterey及更高版本的Mac(Macs)上设置蓝牙(Bluetooth)个人局域网的功能。在旧版本的 macOS 上
使用蓝牙(Bluetooth)网络共享应该没有任何问题。
不间断的互联网连接(Internet Connectivity)
了解如何将您的Android手机设置为便携式 Wi-Fi 热点可以在许多情况下为您提供帮助。但是，当电池寿命受到关注时，不要忘记使用USB或蓝牙网络共享。(Bluetooth)如果您按照上述说明遇到问题，请了解如何修复您的 Android 移动热点并重新上线(fix your Android mobile hotspot and get back online)。
How to Use Your Android Phone as a Hotspot
If your Wi-Fi router at home starts acting up or you travel to an area with nо internet access, setting up a mobile hotspot with your Android phone can quickly help you get othеr deνices back online. We will show you how to do thаt.
Your Android phone allows you to share cellular data with other devices by broadcasting itself as a personal hotspot. It’s a quick and easy way to access the internet when you don’t have access to regular Wi-Fi.
However, setting up your Android device as a mobile hotspot comes at a cost to battery life, so you may want to use it sparingly. For longer sessions, it’s best to explore less conventional methods such as USB and Bluetooth tethering.
Depending on your cellular plan, some carriers may forbid you from sharing mobile data or request you pay extra to tether devices. If you’re in doubt, confirm before you begin.
Note: The following tutorial demonstrates sharing your Android’s internet connection via hotspot, USB, and Bluetooth on a Google Pixel running stock Android 12. The steps below may vary slightly depending on your device and system software version.
Activate Mobile Hotspot on Android
The first time you want to share the internet on your Android cell phone with other devices, you must review the device’s “Wi-Fi hotspot” settings. That allows you to change the default hotspot name, adjust the security level, and note the Wi-Fi password. You can also use a couple of settings to improve battery life and extend compatibility. To do that:
1. Locate and open the Settings app via your Android device’s home screen. Or, open the app drawer and search for it.
2. Tap Network & internet > Hotspot & tethering to access your mobile hotspot and tethering settings page. Then, select Wi-Fi hotspot.
3. Adjust the following settings and turn on the switch next to Use Wi-Fi hotspot:
- Hotspot name: Set up a recognizable network name for your Android’s hotspot feature. If not, it will use the default device name.
- Security: Pick an available Wi-Fi security protocol such as WPA3-Personal, WPA2/WPA3-Personal, and WPA2-Personal. WPA3 features better security but may not be compatible with older devices. Stick to the default WPA2/WPA3 setting or select WPA2 if you encounter connectivity issues.
- Hotspot password: Note down the default hotspot password. It’s a random string of alphanumeric digits, so feel free to change it. However, don’t use an easy-to-guess password.
- Turn off hotspot automatically: Let your Android automatically switch off the mobile hotspot to conserve battery life when no devices are connected.
- Extend compatibility: Allows older devices to detect and use your Android hotspot as a Wi-Fi connection. However, that may cause the battery to drain faster.
You can now connect to your Android phone’s hotspot from another device. The process is similar to joining a typical Wi-Fi network. On your PC or Mac, select the Wi-Fi icon on the system tray or menu bar, select the mobile hotspot name, and enter its password.
It’s also possible to connect an iOS or iPadOS device this way—just head over to the Wi-Fi selection screen to join. You can also tap the QR Code button within the “Wi-Fi hotspot” screen and scan it using the iPhone or iPad camera to join the hotspot instantly without inserting the password. Use Nearby Sharing instead to allow other Android mobile devices to enter the hotspot network.
Going forward, you can turn the hotspot for your Android device on and off via the Quick Settings pane. Just swipe down from the top of the screen to open it (you may have to swipe down twice or sideways to reveal all settings). Then, tap the Hotspot icon to toggle the functionality or long-press it to access the “Wi-Fi hotspot” settings screen.
Again, your Android hotspot uses significant power to stay active. If you haven’t configured the device to turn off the hotspot automatically when no devices are connected, don’t forget to do that and avoid battery drain.
Activate USB Tethering on Android
If you have a USB cable at hand, you can tether your Android to a desktop or laptop device via USB and share your cellular data plan that way. That speeds up the internet and stops the phone’s battery from draining. However, USB tethering prevents you from connecting additional devices and could eat away the battery life on laptops.
1. Open the Settings app on your Android device and tap Network & internet > Hotspot & tethering.
2. Turn on the switch next to USB tethering.
3. Connect your Android to your PC or Mac and disconnect from other wireless networks (or disable the Wi-Fi module). It should automatically start using mobile data via USB.
Unlike a mobile hotspot, you do not need to turn off USB tethering when you aren’t actively using it.
Activate Bluetooth Tethering on Android
It’s also possible to share the internet to a desktop or laptop device on your Android phone via Bluetooth. It results in slower internet speeds and is somewhat complicated to set up and use. However, it drastically reduces battery consumption compared to using a hotspot network.
1. Open the Settings app on your Android device, tap Network & internet > Hotspot & tethering, and turn on the switch next to Bluetooth tethering.
2. Pair your Android phone to your desktop or laptop. In Microsoft Windows, you can open the Start menu and select Settings > Bluetooth & devices > Add a device. On the Mac, open the Apple menu and go to System Preferences > Bluetooth. Make sure to put your Android into discovery mode during the pairing process (just go to Settings > Connected devices).
3. Configure your PC or Mac to start using Bluetooth. In Windows, right-click the Bluetooth icon on the Windows taskbar and select Join Personal Area Network. Or, open the Control Panel and select Hardware and Sound > Devices and Printers. Next, highlight your Android and select Connect to > Access Point.
On the Mac, go to System Preferences > Network, select the Plus icon, and add Bluetooth PAN.
Note: At the time of writing, Apple has removed the ability to set up a Bluetooth personal area network on Macs running macOS 12 Monterey and later. You shouldn’t have any trouble using Bluetooth tethering on older versions of macOS.
Uninterrupted Internet Connectivity
Knowing how to set up your Android phone as a portable Wi-Fi hotspot can help you in many situations. However, don’t forget to use USB or Bluetooth tethering when battery life is a concern. If you run into issues following the instructions above, learn how you can fix your Android mobile hotspot and get back online.
