在Windows 7中连接到无线网络(Wireless Network)
在任务栏的右侧，您将看到如下图所示的无线网络图标(wireless network icon)。点击(Click)它。
将打开一个包含可用网络连接的窗口。正如您从下面的屏幕截图中看到的那样，该列表按可用网络连接的类型划分。
在顶部您有拨号(dial-up)和虚拟专用网络 (VPN)(virtual private network (VPN))连接，而在底部您有一个列表，其中包含Windows 7检测到的所有无线网络。要刷新可用网络列表，请单击下面屏幕截图中突出显示的按钮。
您可以向下滚动可用网络列表。如果您将鼠标光标(mouse cursor)停留在网络上一秒钟，您将看到有关它的更多详细信息。Windows 7 将显示以下信息：网络名称(network name)、信号强度、使用的无线安全类型(type of wireless security used)（如果有）及其服务集标识符 (SSID)(Service Set identifier (SSID))。
一旦您决定连接到哪个网络，请单击它。如果您计划将来使用该网络，请确保选中“自动连接”('Connect automatically')框。这样，当您下次在同一区域启动笔记本电脑时，它会自动连接到此无线网络(wireless network)，而无需任何人工干预。接下来，单击连接(Connect)按钮。
注意：(NOTE:)请谨慎使用未启用安全性的无线网络。它们可用于窃取个人数据。如果您连接到此类网络，请确保您的安全解决方案已打开。
几秒钟后，您将被要求输入安全密钥(security key)。向网络管理员索取无线安全密钥(security key)，或者，如果您在自己的家庭网络(home network)中，请从路由器的控制面板中获取。(control panel)如果您在公共场所，最好选中“隐藏字符”('Hide characters')框，以免其他人看到您正在输入的内容。然后输入安全密钥并(security key and click)单击OK。
如果您输入了错误的密码(incorrect password)，Windows 7将要求您一次又一次地输入，直到它与您连接的网络的密码相匹配。如果一切正常，Windows 7将使用给定的(Windows 7)安全密钥(security key)连接到您选择的网络。连接成功后，任务栏中的无线图标会发生如下变化。
注意：(NOTE:)此过程仅在您的无线适配器(wireless adapter)启用时有效。如果未启用，您将看不到任何可用的无线网络。每个型号的笔记本电脑启用无线适配器(wireless adapter)的过程都不同。
如果您连接到不属于您的无线网络(wireless network)，请确保您知道其管理员提供的密码。如果您不知道网络密码，您的连接将永远无法正常工作。
结论
正如您在本指南中所见，只需几个简单的步骤即可连接到无线网络。如果您有问题，请查看本文第一部分中推荐的文章。对于其他相关文章，请查看我们在下面向您推荐的内容。你会发现一些很好的教程。
How to Connect to Wireless Networks in Windows 7
A growing number of pеoрle use laptops, notebooks and netbooks instead of desktop cоmputеrs. As a result of this trеnd plus the growing number of devices suсh as smartphones, lots of wireless networks appear every day and more people use them on a rеgular basis. Windows 7 offers all you need to connect to wireless networks effortlessly. In this section we will show how to detect wireless networkѕ in Windows 7 and how to сonnect to them.

Troubleshooting Problems with a Wireless Network
If you are having troubles connecting to a wireless network, first check if you followed the correct steps highlighted in the section below. Pay attention to ALL the steps and check if you got them right. If you did everything "by the book" and you still cannot connect, then read the following articles:
Connecting to the Wireless Network in Windows 7
On the right side of the taskbar, you will see a wireless network icon like the one below. Click on it.
A window with available network connections will open. As you can see from the screenshot below, the list is split by the type of available network connections.
At the top you have dial-up and virtual private network (VPN) connections, while at the bottom you have a list with all the wireless networks which Windows 7 has detected. To refresh the list of available networks, click on the button highlighted in the screenshot below.
You can scroll down through the list of available networks. If you leave your mouse cursor over a network for a second, you will see more details about it. Windows 7 will show the following: network name, signal strength, the type of wireless security used (if any) and its Service Set identifier (SSID).
Once you decided on which network to connect to, click on it. If you plan to use that network in the future, make sure you check the box that says 'Connect automatically'. This way, when you start your laptop next time, in the same area, it will automatically connect to this wireless network without requesting any manual intervention. Next, click on the Connect button.
NOTE: be cautious with wireless networks which have no security enabled. They can be used to steal personal data. If you connect to such networks make sure your security solutions are turned on.
After a few seconds, you will be asked to enter the security key. Ask the administrator of the network for the wireless security key or, if you are in your own home network, take it from the control panel of your router. If you are in a public place, it is best to check the 'Hide characters' box so that other people don't see what you are typing. Then type the security key and click on OK.
If you typed an incorrect password, Windows 7 will request you to type it again and again until it matches the password of the network you are connecting to. If everything is OK, Windows 7 will connect to the network you selected using the given security key. When the connection is successful, the wireless icon from your taskbar changes as shown below.
NOTE: this procedure works only if your wireless adapter is enabled. If it is not enabled, you won't see any wireless networks being available. The procedure of enabling the wireless adapter is different for each model of laptop.
If you are connecting to a wireless network which you do not own, make sure you know the password for it from its administrator. If you do not know the password of the network, your connection will never work.
Conclusion
As you can see from this guide, connecting to wireless networks can be done in a few easy steps. In case you have issues, check out the articles recommend in the first section of this article. For other related articles, check out the stuff we recommend you below. You'll find some good tutorials.
