Wireless networks allow computers to communicate without the use of cables. This is also commonly known as Wi-Fi. A connection is made from a device, which is usually a PC or a Laptop with a wireless card, to a Wireless Access Point (WAP), which acts as a bridge between the wireless network and the wired networks. Wireless network standards are specified by IEEE 802.11.

无线网络允许计算机在不使用电缆的情况下进行通信。这也通常称为Wi-Fi。从通常是PC或带无线网卡的笔记本电脑的设备到无线接入点(WAP)建立连接，该无线接入点充当无线网络和有线网络之间的桥梁。无线网络标准由IEEE 802.11指定。

There are many flavors of 802.11, but we will only be concerned with four. Each increases the distance and speed of your wireless network.

802.11有许多种，但是我们将只关注四种。每一种都增加了无线网络的距离和速度。

Name	Speed	Distance	Frequency
802.11a	54 Mbps	30m	5 GHz
802.11b	11 Mbps	91m	2.4 GHz
802.11g	54 Mbps	91m	2.4 GHz
802.11n	540 Mbps	182m	5 and 2.4 GHz

名称	速度	距离	频率
802.11a	54 Mbps的	30m	5 GHz的
802.11b	11 Mbps的	91m	2.4 GHz
802.11g	54 Mbps的	91m	2.4 GHz
802.11n	540 Mbps的	182m	5和2.4 GHz

安全问题 (Security Concerns)

By default, wireless signals can be intercepted and read anyone within range. As such, it is always recommended that you use some form of encryption. Over time there has been many encryption standards:

默认情况下，无线信号可以被拦截并读取范围内的任何人。因此，始终建议您使用某种形式的加密。随着时间的流逝，已经有许多加密标准：

WEP – Wired Equivalent Privacy can be cracked and there are many tutorials on how to do it. For this reason, it has been superseded by stronger encryption techniques such as WPA2.

WEP –有线等效保密可以被**，并且有很多关于如何做到这一点的教程。因此，它已被更强大的加密技术(例如WPA2)所取代。
TKIP – Temporal Key Integrity Protocol was designed by the IEEE and the Wi-Fi Alliance as a solution to replace WEP without requiring the replacement of legacy hardware. TKIP has also been cracked and you should choose a stronger algorithm where available.

TKIP –临时**完整性协议是由IEEE和Wi-Fi联盟设计的，是一种替代WEP的解决方案，而无需替换传统硬件。 TKIP也已被**，您应该在可行的情况下选择更强大的算法。
RADIUS – Remote Authentication Dial In User Service (RADIUS) is a network protocol often used by ISPs and larger enterprises to manage access to both the internet as well as internal networks. RADIUS is what you would use to secure your wireless networks in a corporate environment.

RADIUS –远程身份验证拨入用户服务(RADIUS)是ISP和大型企业经常使用的网络协议，用于管理对Internet和内部网络的访问。 RADIUS是用于在公司环境中保护无线网络的安全性。
WPA – The original WPA standard used TKIP, but was later replaced by WPA2 which uses a more secure AES-based algorithm. WPA is susceptible to brute force attacks when a weak passphrase is used. In most cases, WPA2 is the recommended option to use.

WPA –最初的WPA标准使用TKIP，但后来被WPA2取代，后者使用更安全的基于AES的算法。使用弱密码短语时，WPA容易受到蛮力攻击。在大多数情况下，建议使用WPA2。

连接到无线网络 (Connecting to a Wireless Network)

In the real world we just click on the wireless status icon and select the network we want to connect to, however the exam requires you to know how to connect to a wireless network through the Control Panel. To do that, you will need to open the Network and Sharing Center. This can be done by right clicking on the network connectivity status icon and selecting Open Network and Sharing Center from the context menu.

在现实世界中，我们只需单击无线状态图标并选择我们要连接的网络，但是考试要求您知道如何通过“控制面板”连接到无线网络。为此，您需要打开网络和共享中心。可以通过右键单击网络连接状态图标并从上下文菜单中选择“打开网络和共享中心”来完成。

Then click on the Set up a new connection or network link.

然后单击“设置新连接或网络”链接。

Next you will want to select manually connect to a wireless network, then click next.

接下来，您将要选择手动连接到无线网络，然后单击下一步。

Next you will need to:

接下来，您将需要：

Enter the SSID of your network
输入您的网络的SSID
Select the security type for your network
选择您网络的安全类型
Select the encryption scheme your network uses
选择您的网络使用的加密方案
Then type in the password for the network
然后输入网络密码

Once you have entered all that click next.

输入所有内容后，单击“下一步”。

You should then get a message stating you have successfully added the network. At this point you can close the wizard.

然后，您将收到一条消息，指出您已成功添加网络。此时，您可以关闭向导。

You should now see your wireless network status icon change to white and show you the signal strength.

现在，您应该看到无线网络状态图标变为白色，并向您显示信号强度。

导出无线网络配置文件 (Exporting Wireless Network Profiles)

If you need to setup wireless network connectivity on multiple machines, you can export your wireless network profile to a file and import it on the other machines. To do that again open the Network and Sharing Center but this time click on the manage wireless networks link in the left hand pane.

如果需要在多台计算机上设置无线网络连接，则可以将无线网络配置文件导出到文件中，然后将其导入其他计算机上。为此，请再次打开“网络和共享中心”，但这一次单击左侧窗格中的“管理无线网络”链接。

Then right click on the network you want to export and select Properties from the context menu.

然后右键单击要导出的网络，然后从上下文菜单中选择“属性”。

To export the network profile click on the link near the bottom of the dialog. If a USB is plugged in, a wizard will appear that will guide you through the remainder of the export process.

要导出网络配置文件，请单击对话框底部附近的链接。如果插入了USB，将出现一个向导，指导您完成其余的导出过程。

导入无线网络配置文件 (Importing a Wireless Network Profile)

Once you have a network profile saved on a removable drive you will need to go to the other computer and insert the drive. When the auto play dialog opens, you will see a new option to connect to a wireless network. You will want to click on it.

将网络配置文件保存在可移动驱动器上后，您需要转到另一台计算机并插入驱动器。当自动播放对话框打开时，您将看到一个新选项以连接到无线网络。您将要单击它。

You will then be asked if you want to add the computer to the network. Clicking yes is all it takes to get connected.

然后将询问您是否要将计算机添加到网络。单击“是”即可建立连接。

设置首选无线网络 (Setting a Preferred Wireless Network)

If you are situated in an area that gets signal from more than one access point, you normally want to connect to the one that has a stronger signal. If you find yourself in a situation where Windows always connects to the weaker access point you can manually change the priority of the networks. To do this, open the Network and Sharing Center again.

如果您位于从多个接入点接收信号的区域中，则通常需要连接到信号较强的接入点。如果发现Windows总是连接到较弱的访问点，则可以手动更改网络的优先级。为此，请再次打开网络和共享中心。

Then click on the Manage wireless networks link in the left hand pane.

然后，单击左侧窗格中的“管理无线网络”链接。

Now select the network with the strong signal and click the move up button.

现在选择信号较强的网络，然后单击上移按钮。

That’s all there is to it.

这里的所有都是它的。

临时网络 (Ad-Hoc Networks)

An 802.11 wireless network adapter can operate in two modes, Ad-Hoc and Infrastructure. Infrastructure mode is the way you have probably always used Wi-Fi, where you connect to an access point. In Ad-hoc mode your computers talk directly to each other and do not need an access point, however the computers have to be within 30m of each other. To create an ad-hoc network head into the network and sharing center and click on the set up a new connection or network link.

802.11无线网络适配器可以在两种模式下运行，即席模式和基础结构。基础架构模式是您可能一直使用Wi-Fi的方式，您可以在其中连接到接入点。在Ad-hoc模式下，您的计算机直接相互通信，不需要访问点，但是计算机之间的距离必须在30m之内。要创建临时网络，请进入网络和共享中心，然后单击设置新的连接或网络链接。

Then scroll all the way to the bottom and choose to setup an ad-hoc network, then click next.

然后一直滚动到底部，并选择设置一个临时网络，然后单击下一步。

Next give your network a name and a password, then click next.

接下来，为您的网络命名和密码，然后单击下一步。

Once completed, users will be able to connect to the network just as they would an infrastructure based network.

完成后，用户将能够连接到网络，就像基于基础结构的网络一样。
