尽管路由器具有自己的安全功能，但入侵他人的路由器并非不可能。一旦有人可以访问其他人的无线路由器，他或她不仅可以使用他们的带宽，还可以访问网络中的计算机，尤其是在家庭网络中。最糟糕(Worst)的是，他们可以将您的WiFi用于非法目的。有一些简单的步骤可以保护您的WiFi。我们还将讨论一种工具，可让您检查谁都连接到您的WiFi连接。
如何保护您的 WiFi
有人在尝试登录您的路由器时遇到的第一件事是路由器 ID 和密码。你必须把它设置成好的东西。随机字符串会很好。硬密码很容易创建，但很难记住。您可以使用密码管理器为您生成密码，也可以自己创建一个。如果您使用的是密码管理器，它会自动填写您进入路由器页面所需的凭据。以下说明如何更改您的路由器 ID 和密码。
更改路由器的密码
要登录您的路由器，您需要路由器的配置页面。您必须在浏览器中输入其 IP 地址。大多数情况下，路由器的 IP 是 192.168.1.1。如果您无法使用该 IP 进入路由器页面，请打开命令提示符窗口，然后键入ipconfig /all。记下网关(Gateway)的 IP 地址。尝试在浏览器的地址栏中输入该地址。如果这也不起作用，请在查看路由器手册后致电路由器的客户服务中心，看看那里是否提到了地址。
要更改路由器的密码和 ID，您必须登录路由器。在许多公司的路由器上，默认 ID 是admin。默认密码为空。如果它不是空白，它可能是1234或0000，就像手机一样。它也可能是密码(password)。在致电路由器公司的客户服务部门之前，请尝试使用这些密码，包括空白密码。您还可以查看路由器手册，看看那里是否提到了密码和 ID。

WPA2 协议
您在家中的网络上有什么样的安全措施？查看(Look)您的 Wi-Fi 设置。它可以是无担保的或使用WEP、WPA或WPA2保护的。WPA比WEP好，但WPA2最好。将您的网络安全设置更改为WPA2。
阅读(Read)：WPA、WPA2 和 WEP Wi-Fi 协议之间的区别(Difference between WPA, WPA2 & WEP Wi-Fi Protocols)。
保护您的 WiFi 的其他步骤
需要另一个密码才能连接到路由器的无线连接。这可以在浏览器中路由器页面的无线（或相关选项卡）下找到。(Wireless)也要严格：不可猜测，有点长，包括特殊字符。这是您在可用无线网络列表(List of available wireless networks)下选择网络后输入的密码。有些人很容易破解这些密码。我记得一个邻居的名字是SSID，他的职业是密码。永远(Don)不要那样做。创建一个严格的密码并将其存储在您的手机或Google Keep等设备上。
当您仍在浏览器中的路由器页面上时，请检查其加密类型。如果还没有，请选择WPA2。其他一些选项显示了加密方法的组合。如果WPA2不能单独使用，请选择WPA2-PSK。保存配置并登录到您的无线连接以查看它是否正常工作。如果不是，请将加密类型降级为WPA-PSK/WPA2-PSK。那应该可以解决问题。不要选择WEP，因为它的保护性不强。
谁在我的 WiFi 上
尽管您可以通过“计算机(Computer)”窗口进行检查，但我们建议您使用免费工具，该工具不仅可以告诉您连接了多少台计算机，还可以让您阻止未知计算机。从 这里(here)(here)下载(Download)免费软件Who is on My WiFi并安装它。这个工具，像Wireless Network Watcher 和 Zamzom Wireless Network Tool(Wireless Network Watcher and Zamzom Wireless Network Tool)，会告诉你谁都在使用你的 WiFi(who all are using your WiFi)。谁(Who)在我的 WiFi(My WiFi)上的免费版本足以知道所有计算机连接到您的WiFi并阻止未知计算机。
当您第一次运行“谁在我的 WiFi 上”时，它会扫描网络以查找所有连接的计算机，并为您提供许多详细信息，包括它们的最后一个 IP 地址和MAC ID(MAC IDs)。这很重要，因为您可以使用每台计算机的MAC ID来验证所有计算机是否都是您的。
注意：(NOTE:)立即扫描(Scan Now)按钮位于软件的主窗口中。不要混淆；检查程序窗口的右上角。
Also, note that the program will notify/show only the computers that are currently connected to your router/WiFi. If any computer is switched off, it won’t be shown. Make sure all your computers are ON before running the scan.
重要提示：(IMPORTANT:)您将在结果对话框中看到另外一行。那是你的路由器。你会知道，因为当你试图阻止它时，软件会告诉你“你不能阻止你的路由器”。
如果计算机尚未使用Windows 安装(Windows Installation)中的计算机名称命名，则您可以随后命名这些计算机。请记住(Remember)单击“保存(SAVE)” ，否则您将继续收到有关未知计算机的警告。当您单击X按钮关闭程序时，它会继续在您的系统托盘中运行，以持续监控是否有任何未知计算机连接到您的WiFi。
提示：(TIP:)要知道计算机的Mac ID，请打开适配器属性(Adapter Properties)（在网络(Networks)和共享(Sharing)下），然后将鼠标悬停在连接使用(CONNECT USING)上。
因此，我试图告诉您如何使用路由器配置页面以及通过第三方软件保护WiFi - 以及如何知道有多少和所有计算机连接到您的(WiFi)WiFi - 使用“谁在我的WiFi “ 软件。
如果您有什么要分享的，请发表评论。(If you have anything to share, please comment.)

How To Secure Your WiFi - Know Who Are Connected
Though routers comе with their own security features, it iѕ not impossible to hack into others’ routers. Once somеone gains access to somеone elsе’s wireless routеr, he or she can not only use their bandwidth but also gain access to the computers in the network, especially if it is a home network. Worst of all, they can usе your WiFi for illegal purpoѕes. There arе some simple steps to secure your WiFi. We will alѕo talk about a tool that lets yoυ check who all are connected to your WiFi connection.
How to Secure your WiFi
The first thing someone encounters when he or she tries to log into your router is the router ID and password. You have to set it to something good. A random string would be good. Hard passwords are easy to create but tough to remember. You can use a password manager to generate a passcode for you, or you can create one on your own. If you are using a password manager, it would automatically fill in the credentials you need to enter the router page. The following explains how to change your router ID and password.
Change Password of Your Router
To log into your router, you need your router’s configuration pages. You have to type its IP address into a browser. The IP of the router is 192.168.1.1 in most cases. If you cannot get into the router page using that IP, open command prompt window, and type ipconfig /all. Note down the IP address of the Gateway. Try typing in that address into the address bar of your browser. If that too does not work, call up your router’s customer care after checking your router manual to see if the address is mentioned there.
To change the password and ID of your router, you have to log in to your router. The default ID is admin on routers of many companies. The default password is blank. If it is not blank, it could be 1234 or 0000 as in the case of cellphones. It might also be password. Try using these passwords, including the blank one before calling up the router company’s customer care. You can also look into the router manual to see if the passcodes and ID are mentioned there.

WPA2 protocol
What kind of security do you have on your network at home? Look at your Wi-Fi settings. It could be unsecured or secured with WEP, WPA or WPA2. WPA is better than WEP, but WPA2 is best. Change your network security settings to WPA2.

Other Steps To Safeguard Your WiFi
Another password is required to connect to your router’s wireless connection. This is found under the Wireless (or relevant tab) of your router’s page in the browser. Make it strict too: non-guessable, a little long and include special characters. This is the password you enter after selecting a network under List of available wireless networks. Some people make it very easy to crack these passwords. I remember one neighbor having his name as SSID and his profession as his password. Don’t ever do that. Create a tough password and store it on something like your phone or Google Keep, etc.
While you are still on the router’s page in your browser, check its encryption type. If not already, select WPA2. Some other options show a combination of encryption methods. If WPA2 is not available separately, select WPA2-PSK. Save the configuration and log into your wireless connection to see if it is working. If not, downgrade the encryption type to WPA-PSK/WPA2-PSK. That should solve the problem. Do not go for WEP as it is not very protective.
Who Is On My WiFi
Though you can check it through the Computer window, we recommend using a free tool that not only tells you how many computers are connected but also gives you the power to block unknown computers. Download freeware Who is on My WiFi from here and install it. This tool, like Wireless Network Watcher and Zamzom Wireless Network Tool, will show you who all are using your WiFi. The free version of Who Is On My WiFi is enough to know what all computers are connected to your WiFi and to block unknown computers.
The first time you run “Who is on My WiFi”, it scans the network for all the computers connected and provides you with many details including their last IP address and MAC IDs. This is important as you can verify if all computers are yours – using the MAC ID of each machine.
NOTE: The Scan Now button is in the main window of the software. Do not get confused; check the top right corner of the program window.
Also, note that the program will notify/show only the computers that are currently connected to your router/WiFi. If any computer is switched off, it won’t be shown. Make sure all your computers are ON before running the scan.
IMPORTANT: You will see one additional row in the results dialog box. That is your router. You will know because when you try to block it, the software will tell you “you cannot block your router”.
You can then name the computers if they are not already named using the computer name from Windows Installation. Remember to click SAVE else you will keep receive warnings about unknown computers. When you click the X button to close the program, it keeps running in your system tray to keep monitoring if any unknown computer connects to your WiFi.
TIP: To know the Mac ID of a computer, open Adapter Properties (under Networks and Sharing), and hover your mouse over CONNECT USING.
Thus, I have tried to tell you how to secure WiFi using the router configuration page as well as through third-party software – and also how to know how many and what all computers are connected to your WiFi – using “Who is on My WiFi” software.
