wi-fi和路由器怎么连接
If you live in an apartment complex, you’ve probably noticed more than just the passive-aggressive network IDs that your neighbors use—very likely you’ve had problems with your wireless connections dropping out, or just not being as fast as you’d like. This often has to do with the Wi-Fi channels in your area.
如果您住在公寓大楼中，您可能会注意到不仅仅是邻居使用的被动攻击性网络ID，这很可能是您的无线连接掉线或速度不如您所遇到的问题d喜欢。 这通常与您所在地区的Wi-Fi频道有关。
If you’re on the same Wi-Fi channel as a lot of your neighbors, you’ll experience a lot of interference with their networks—so it’s best to choose a different channel with fewer people on it. When you do, you’ll reduce that interference and improve your WI-Fi signal.
如果您与许多邻居在同一个Wi-Fi频道上，则您的网络将受到很多干扰，因此最好选择人数较少的其他频道。 完成后，您将减少干扰并改善WI-Fi信号 。
The first step, though, is finding out which channel is least congested in your area. These tools will help you identify which nearby networks are using which channels.
不过，第一步是找出您所在地区最不拥挤的频道。 这些工具将帮助您确定附近的哪些网络正在使用哪些频道。
Note that Wi-Fi channels overlap with nearby channels. Channels 1, 6, and 11 are the most frequently used for 2.4 GHz Wi-Fi, and these three are the only ones that don’t overlap with each other.
请注意，Wi-Fi频道与附近的频道重叠。 通道1、6和11是2.4 GHz Wi-Fi最常用的通道，这三个通道是唯一不重叠的通道。
Windows： NirSoft WifiInfoView (Windows: NirSoft WifiInfoView)
We previously recommended inSSIDer for this on Windows, but it’s become paid software. You probably don’t want to pay $20 just to figure out which Wi-Fi channel is ideal, so use a free tool instead.
我们以前在Windows上为此推荐inSSIDer ，但它已成为付费软件。 您可能不想只花20美元来弄清楚哪个Wi-Fi通道是理想的，所以请改用免费工具。
Xirrus Wi-Fi Inspector is very powerful, but it’s a bit overkill for this. We liked NIrSoft’s WifiInfoView instead — its simple interface does the job and it doesn’t need any installation. Launch the tool, locate the Channel header, and click it to sort by Wi-Fi channel. Here, we can see that channel 6 looks a bit cluttered — we might want to switch to channel 1 instead.
Xirrus Wi-Fi检查器功能非常强大，但是这样做有些过头了。 相反，我们更喜欢NIrSoft的WifiInfoView －它的简单界面可以完成工作，并且不需要任何安装。 启动该工具，找到“通道”标题，然后单击它以按Wi-Fi通道排序。 在这里，我们可以看到通道6看起来有些混乱-我们可能想改用通道1。
Mac：无线诊断 (Mac: Wireless Diagnostics)
Believe it or not, macOS actually has this feature integrated. To access it, hold the Option key and click the Wi-Fi icon on the menu bar at the top of your screen. Select “Open Wireless Diagnostics.”
信不信由你，macOS实际上集成了此功能。 要访问它，请按住Option键，然后单击屏幕顶部菜单栏上的Wi-Fi图标。 选择“打开无线诊断”。
Ignore the wizard that appears. Instead, click the Window menu and select Utilities.
忽略出现的向导。 而是单击“窗口”菜单，然后选择“实用程序”。
Select the Wi-Fi Scan tab and click Scan Now. The “Best 2.4 GHz Channels” and “Best 5 GHz” Channels” fields will recommend the ideal Wi-Fi channels you should be using on your router.
选择“ Wi-Fi扫描”选项卡，然后单击“立即扫描”。 “最佳2.4 GHz通道”和“最佳5 GHz”通道”字段将建议您应该在路由器上使用的理想Wi-Fi通道。
Linux：iwlist命令 (Linux: The iwlist Command)
You could use a graphical app like Wifi Radar for this on Linux, but you’d have to install it first. Instead, you might as well just use the terminal. The command here is installed by default on Ubuntu and other popular Linux distributions, so it’s the fastest method. Don’t fear the terminal!
您可以在Linux上使用Wifi Radar之类的图形应用程序，但是必须首先安装它。 相反，您最好只使用终端。 默认情况下，此处的命令已安装在Ubuntu和其他流行的Linux发行版上 ，因此这是最快的方法。 不要害怕终端！
Open a Terminal and run the following command:
打开终端并运行以下命令：
sudo iwlist wlan0 scan | grep \(Channel
sudo iwlist wlan0扫描| grep \(频道
Read the output of the command to see which channels are the most congested and make your decision. In the screenshot below, channel 1 looks the least congested.
阅读命令的输出以查看哪些信道最拥挤，然后做出决定。 在下面的屏幕截图中，频道1的拥塞程度最低。
Android： Wifi分析器 (Android: Wifi Analyzer)
If you want to search for Wi-Fi channels on your phone instead of your PC, the easiest-to-use application we’ve found is Wifi Analyzer on Android. Just install the free app from Google Play and launch it. You’ll see an overview of the wireless networks in your area and which channels they’re using.
如果您想在手机而不是PC上搜索Wi-Fi频道，我们发现最容易使用的应用程序是Android上的Wifi分析器。 只需安装Google Play中的免费应用并启动即可。 您将看到您所在区域的无线网络及其使用的信道的概述。
Tap the View menu and select Channel rating. The app will display a list of Wi-Fi channels and a star rating — the one with the most stars in the best. The app will actually tell you which Wi-Fi channels are better for your Wi-Fi network, so you can go straight to your router’s web interface and choose the ideal one.
点击查看菜单，然后选择频道评级。 该应用程序将显示一个Wi-Fi频道列表和一个星级(最高星级的星级)。 该应用程序实际上会告诉您哪些Wi-Fi通道更适合您的Wi-Fi网络，因此您可以直接转到路由器的Web界面并选择理想的Wi-Fi通道。
iOS： 机场实用程序 (iOS: Airport Utility)
Update: We’ve been informed you can do this with Apple’s own AirPort Utility application. Enable and use the “Wi-Fi Scanner” feature inside the app.
更新 ：我们已经通知您可以使用Apple自己的AirPort Utility应用程序执行此操作。 在应用程序内启用并使用“ Wi-Fi扫描仪”功能。
This isn’t possible on iPhones and iPads. Apple restricts apps from accessing this Wi-Fi data directly from the hardware, so you can’t get an app like Android’s Wifi Analyzer on Apple’s App Store.
在iPhone和iPad上这是不可能的。 Apple限制应用程序直接从硬件访问此Wi-Fi数据，因此您无法在Apple App Store上获得像Android的Wifi Analyzer这样的应用程序。
If you jailbreak, you can install an app like WiFi Explorer or WiFiFoFum from Cydia to get this functionality on your iPhone or iPad. These tools moved to Cydia after Apple booted them from the official App Store.
如果您越狱 ，则可以从Cydia安装WiFi Explorer或WiFiFoFum之类的应用，以在iPhone或iPad上获得此功能。 在Apple从官方App Store启动它们之后，这些工具便移至Cydia。
You probably wouldn’t want to go through the trouble of jailbreaking just for this, so use one of the other tools here instead.
您可能不想为此而经历越狱的麻烦，所以请改用这里的其他工具之一。
如何更改路由器的Wi-Fi频道 (How to Change Your Router’s Wi-Fi Channel)
Once you’ve found the least congested channel, changing the channel your router uses should be simple. First, log into your router’s web interface in your web browser. Click over to the Wi-Fi settings page, locate the “Wi-Fi Channel” option, and choose your new Wi-Fi channel. This option may be on some sort of “Advanced Settings” page, too.
找到最不拥挤的信道后，更改路由器使用的信道应该很简单。 首先， 在网络浏览器中登录路由器的网络界面 。 单击进入Wi-Fi设置页面，找到“ Wi-Fi频道”选项，然后选择新的Wi-Fi频道。 此选项也可能在某种“高级设置”页面上。
If there are too many other nearby networks interfering with your signal, try getting a router that supports 5 GHz (like a “Dual Band” router). 5 GHz Wi-Fi channels are farther apart and won’t interfere with each other as much.
如果附近有太多其他网络干扰您的信号，请尝试购买支持5 GHz的路由器 (例如“双频”路由器)。 5 GHz Wi-Fi通道相距较远，彼此之间的干扰不会太大。
