通过USB电缆将移动智能手机上可用的互联网数据连接与 Windows PC 共享称为USB 网络共享(USB tethering)。换句话说，如果您想知道“什么是 USB 网络共享？” ("what is USB tethering?")，答案很简单：这是一种将您的Android智能手机用作调制解调器或路由器，通过USB在任何 PC 上获取移动互联网的方式。假设(Say)您在家中可以访问 Wi-Fi 网络，但您的台式 PC 中没有无线网卡。您可能想使用Android的USB网络共享功能以在它们之间建立连接。或者，如果您发现自己处于除了Android(Android)手机上的大量移动数据计划之外没有任何互联网访问权限的情况怎么办。您可能想将其中的一部分提供给您的Windows计算机和设备，对吧？以下是通过USB从(USB)Android手机共享互联网到任何 PC的方法：
注意：(NOTE:)为了创建本指南，我们使用了运行Android 10的(Android 10)华为 P20(Huawei P20)智能手机。尽管某些屏幕截图在运行其他版本或版本 Android(version of Android)的智能手机上可能会有所不同，但大多数设置的外观和工作方式应该相同。
第 1 步：在您的Android(Android)智能手机上启用互联网
您应该做的第一件事是确保您的Android智能手机具有互联网连接。最简单的方法是使用快速设置(Quick settings)面板。要找到它，请用手指从屏幕顶部轻扫 - 如果看不到，请轻扫两次。然后，在操作面板上，查找Wi-Fi或移动数据(Mobile data)按钮，然后点击要启用并用作USB网络共享的 Internet 源的 Internet 连接。
设置(Settings)应用程序还为您提供了另一种在Android上启用互联网连接的方法。从屏幕顶部滑动手指，然后点击“设置”(Settings)按钮。这是一个看起来像一个小齿轮。有关打开设置(Settings)的更多方法，请阅读：进入 Android 设置菜单的 5 种方法(5 ways to get to the Android Settings menu)。
然后，如果您想在您的Android上使用无线网络连接到互联网，请转到Wi-Fi，将其打开，选择并连接到 Wi-Fi 网络。
如果您没有Wi-Fi访问权限，或者您更喜欢将移动数据计划用作USB网络共享的互联网来源，请在设置(Settings)屏幕上转到移动网络(Mobile network)。查找名为移动数据(Mobile data)的条目并确保其开关已打开。
第 2 步。使用USB电缆将您的Android智能手机连接到您的Windows PC(Windows)
使用USB电缆将您的Android智能手机连接到您的Windows PC。如果您仍然拥有它，最好使用随Android智能手机收到的原装USB 数据(USB)线。如果您使用台式电脑，还建议使用背面的USB端口之一插入USB电缆。它们通常比前面的那些更快、更可靠。
步骤 3. 在您的Android(Android)智能手机上打开USB网络共享功能（从Android共享互联网到 PC）
将Android智能手机连接到Windows PC 后，返回智能手机并再次打开其设置(Settings)。然后，转到移动网络(Mobile network)并点击以打开网络共享和便携式热点(Tethering & portable hotspot)设置面板。在那里，打开USB 网络共享(USB tethering)开关。
第 4 步。等待(Wait)一两分钟，直到您的 Windows PC 安装所需的驱动程序
在您的Windows PC 上，您可能会看到操作系统安装了一系列驱动程序，这些驱动程序是USB网络共享工作所必需的。这是因为您的Android智能手机用作USB调制解调器，而您的Windows PC 需要相应的驱动程序。此过程应立即完成，并且仅在您第一次使用Android智能手机通过(Android)USB电缆连接到 PC 上的互联网时才会发生。
就是这样！现在，您应该可以通过连接到您的Android智能手机或平板电脑的USB电缆在您的(USB)Windows PC上连接互联网。打开您喜欢的网络浏览器并开始浏览网络。
以一两个警告结束
虽然通过Android(Android)智能手机的USB连接很容易连接到互联网，但请记住以下几点：
- 如果您使用的是移动数据计划，则如果超出计划的界限，则可能会产生高额费用，具体取决于您与移动运营商的合同。
- 通过USB使用智能手机的互联网连接时，智能手机的充电速度可能比平时慢。虽然这可能是一件好事，因为它不会让您的智能手机的电池耗尽，但如果您的Windows设备是笔记本电脑或未连接电源插头的平板电脑，这也可能是一个问题。除非你的Windows设备连接到电源插座，否则它的电池会比平时更快耗尽，因为它也在为你的 Android 设备充电。
您是否通过USB(USB)与笔记本电脑或 PC共享移动互联网？
现在您知道使用Android智能手机或平板电脑在任何(Android)Windows PC上访问互联网是多么容易，无论是台式电脑、笔记本电脑、二合一电脑还是平板电脑。您觉得USB网络共享功能有用吗？你经常使用它吗？请在下面的评论中告诉我们。
How to share internet from an Android smartphone to a PC via USB
Sharing the internet data connection available on your mobile smartphone with your Windows PC through a USB cable is called USB tethering. In other words, if you're wondering "what is USB tethering?", the answer is quite simple: it's a way of using your Android smartphone as a modem or router to get mobile internet via USB on any PC. Say you have access to a Wi-Fi network in your home but your desktop PC doesn't have a wireless card in it. You might want to use your Android's USB tethering feature to establish a connection between them. Or, what if you find yourself in a situation where you don't have any internet access except for your generous mobile data plan on your Android phone. You might want to give some of that to your Windows computers and devices, right? Here's how to share internet from an Android phone to any PC via USB:
NOTE: To create this guide, we used a Huawei P20 smartphone running Android 10. Although some screenshots might differ a bit on a smartphone running another flavor or version of Android, most settings should look and work the same.
Step 1. Enable internet on your Android smartphone
The first thing you should do is make sure that your Android smartphone has internet connectivity. The easiest way to do that is from the Quick settings panel. To get to it, swipe with your finger from the top of the screen - if you don't see it, swipe twice. Then, on the actions panel, look for the Wi-Fi or Mobile data buttons and tap on the internet connection that you want to enable and use as the internet source for USB tethering.
The Settings app also offers you an alternative method to enable the internet connection on your Android. Slide your finger from the top of the screen and tap on the Settings button. It's the one that looks like a small gear. For more ways to open Settings, read: 5 ways to get to the Android Settings menu.
Then, if you want to use a wireless network to connect to the internet on your Android, go to Wi-Fi, turn it on, select and connect to a Wi-Fi network.
If you don't have Wi-Fi access or if you prefer to use your mobile data plan as the internet source for USB tethering, on the Settings screen, go to Mobile network. Look for an entry called Mobile data and make sure that its switch is turned on.
Step 2. Connect your Android smartphone to your Windows PC using a USB cable
Use a USB cable to connect your Android smartphone to your Windows PC. If you still have it, it's preferable that you use the original USB cable that you received with your Android smartphone. If you use a desktop PC, it's also recommended to use one of the back USB ports to plug the USB cable. They are usually faster and more reliable than those on the front.
Step 3. Turn on the USB tethering feature on your Android smartphone (share internet from Android to PC)
Once you've connected your Android smartphone to your Windows PC, get back to your smartphone and open its Settings again. Then, go to the Mobile network and tap to open the Tethering & portable hotspot settings panel. There, turn the USB tethering switch on.
Step 4. Wait for a moment or two until your Windows PC installs the required drivers
On your Windows PC, you might see the operating system install a series of drivers that are necessary for the USB tethering to work. That's because your Android smartphone works as a USB modem and your Windows PC needs the appropriate drivers for it. This process should be done in a moment, and it's something that takes place only the first time you use your Android smartphone to connect to the internet on your PC through a USB cable.
That was it! Now you should have internet connectivity on your Windows PC, through the USB cable that is connected to your Android smartphone or tablet. Open your favorite web browser and start browsing the web.
Ending with a warning or two
Although connecting to the internet through your Android smartphone's USB connection is easy, keep in mind the following points:
- If you're using your mobile data plan, that can incur high costs if you overstep your plan's boundaries, depending on your contract with the mobile operator.
- While using your smartphone's internet connection through USB, the smartphone might charge slower than usual. Although that can be a good thing because it doesn't let your smartphone's battery die, it can also be a problem if your Windows device is a laptop or a tablet that is not connected to a power plug. Unless your Windows device is connected to a power socket, its battery will deplete faster than usual, because it's also charging your Android device.
Do you share mobile internet via USB to your laptop or PC?
Now you know how easy it is to use your Android smartphone or tablet to get internet access on any Windows PC, whether it's a desktop computer, a laptop, a 2-in-1, or a tablet. Do you find the USB tethering feature useful? Do you use it often? Let us know in the comments below.
