将Apple TV(Apple TV)连接到 Wi-Fi 网络时，是否收到“无法加入网络”错误消息？我们将解释导致此错误的一些因素以及如何修复它们。
首先(First)，Apple TV不适用于强制网络——即带有辅助登录页面的Wi-Fi网络。(Wi-Fi)这意味着流媒体设备可能无法连接到酒店、公寓大楼、学校宿舍和其他公共场所的Wi-Fi网络。相反，请将您的Apple TV连接到专用网络或联系（公共）网络管理员以授予您的Apple TV直接访问Wi-Fi网络的权限。
如果您的Apple(Apple) TV 无法连接到Wi-Fi并显示专用网络的“无法加入网络”错误，请尝试以下修复。
快速提示： tvOS 故障排除页面提供了有用的建议，用于解决(Quick Tip:)Apple TV上常见的网络相关问题。启动“设置”(Settings)应用程序并转到“网络(Network)” > “故障排除”(Troubleshooting)以检查它们。
1.重新启动(Restart)并重新定位您的 Wi-Fi 路由器(Reposition Your Wi-Fi Router)
重新启动路由器将清除其缓存并解决连接问题。但在重新启动路由器之前，请确保它靠近您的Apple TV。无线路由器与Apple TV越近，连接强度和性能就越好。事实上，Apple建议将Apple TV和Wi-Fi路由器放在同一个房间。或者至少离路由器不太远。
您还应该确保您的Apple TV 与路由器有清晰的视线。墙壁(Walls)、厨房微波炉、镜子、婴儿监视器和发射无线电信号的设备会阻挡网络信号。调整路由器的外接天线并移除任何可能导致信号干扰的设备。
我们在本文中重点介绍了增强弱 Wi-Fi 信号的方法(ways to boost a weak Wi-Fi signal in this article)。通过它了解更多网络故障排除提示。如果没有任何效果，请关闭路由器或将其从电源上拔下。一两分钟后重新打开它，然后尝试再次将Apple TV 连接到网络。
2.忘记其他网络
如果您的Apple TV 无法连接到您首选的 Wi-Fi(Wi-Fi)网络，请执行此操作。或者，如果设备不断加入没有互联网连接的不受欢迎的网络(network with no internet connection)。忘记有问题的网络并连接到您的首选网络。
打开设置(Settings)应用程序，选择网络(Network)，选择Wi-Fi，选择棘手的网络，然后选择忘记网络(Forget Network)。
如果您的Apple TV 仍未加入 Wi-Fi 连接，则可能是网络上的设备过多。网络管理员也可能阻止您的Apple TV 加入网络。请联系网络管理员或查看下一部分以了解如何在路由器的设置菜单中取消阻止Apple TV。(Apple)
3.检查您的路由器设置
许多无线路由器具有阻止设备使用无线互联网连接的(block devices from using wireless internet connections)安全措施。例如，如果Apple TV处于MAC 地址限制或过滤器(MAC Address Restriction or Filter)之下，它就不会连接到Wi-Fi。
如果您有权访问路由器的管理面板，请前往设备管理部分，并检查您的Apple TV 是否有权访问网络。将您的Apple TV 列入白名单或将其从任何限制中移除。
最好准备好Apple TV 的MAC地址，以防路由器按MAC地址索引设备。
前往“设置”(Settings) > “通用(General)” > “关于(About)”并记下Wi-Fi 地址(Wi-Fi Address)行中的字符。
本指南将家庭网络上的特定设备列入白名单(guide on whitelisting specific devices on your home network)有详细说明。更好(Better)的是，请参阅路由器的说明手册或访问制造商的网站。
4.重启你的苹果电视
重启流媒体设备可以解决临时系统故障，阻止其连接或保持连接到Wi-Fi和以太网(Ethernet)网络。从电源插座上拔下Apple TV，然后重新插入。(Apple)
或者，转到设置(Settings)>系统(System)并选择重新启动(Restart)。
要重新启动较旧的Apple TV 机型（第 3 代Apple TV 或更早机型），请前往“设置”(Settings) > “通用(General)”并选择“重新启动(Restart)” 。
5. 重置您的 Wi-Fi 路由器
如果没有设备可以加入网络，最好将路由器的设置重置为出厂默认设置。阅读我们关于重置无线路由器的指南，(guide on resetting wireless routers)或参阅路由器的说明手册以获取特定于设备的说明。
6. 更新您的 Apple TV
如果您的Apple TV操作系统过时或存在错误，它可能会断开Wi-Fi连接或无法加入无线网络。(Wi-Fi)当然，安装 tvOS 更新需要互联网连接。但由于您的Apple TV 无法连接到Wi-Fi，您有两种选择：使用以太网(Ethernet)连接或执行基于计算机的出厂重置。
将(Plug)以太网(Ethernet)电缆插入Apple TV，前往“设置”(Settings) > “系统(System)” > “软件更新”，(Software Update,)然后选择“更新软件”以在(Update Software)Apple TV上下载并安装最新的 tvOS 版本。
要更新第 3 代Apple TV(Apple TVs)，请前往“设置”(Settings) > “通用(General)” > “软件更新(Software Updates)” ，然后选择“更新软件”(Update Software)。
如果您没有以太网连接，您可以使用(Ethernet)Mac或Windows电脑通过执行恢复出厂设置来远程更新Apple TV 。这将删除您的帐户并删除所有设置、配置和第三方应用程序。但从积极的方面来说，该操作会在您的 Apple TV 上下载并安装最新的 tvOS 版本(install the latest tvOS version on your Apple TV)。同样，它将消除阻止Apple TV 建立 Wi-Fi 连接的错误和软件冲突。
在尝试了上面列出的所有故障排除步骤后，您应该只在Apple TV 无法连接到Wi-Fi时执行恢复出厂设置。

FIX: Apple TV Won’t Connect to Wi-Fi
Do you get an “Unable to join the network” error messаge when you connect your Apple TV to a Wi-Fi network? We’ll explain some factors responsible for this error and how to get them fixed.
First off, Apple TV doesn’t work with captive networks—i.e., Wi-Fi networks with a secondary login page. This means the streaming device may fail to connect to Wi-Fi networks in hotels, apartment complexes, school dorms, and other public locations. Instead, connect your Apple TV to a private network or contact the (public) network admin to grant your Apple TV direct access to the Wi-Fi network.
Try the fixes below if your Apple TV won’t connect to Wi-Fi and displays the “Unable to join the network” error for private networks.
Quick Tip: The tvOS troubleshooting page has useful recommendations for fixing common network-related problems on Apple TV. Launch the Settings app and go to Network > Troubleshooting to check them out.
1. Restart and Reposition Your Wi-Fi Router
Rebooting your router will clean out its cache memory and resolve connectivity issues. But before you restart the router, make sure it’s close to your Apple TV. The closer your wireless router and Apple TV, the better the connection strength and performance. In fact, Apple recommends having your Apple TV and Wi-Fi router in the same room. Or at least not too far from the router.
You should also ensure that your Apple TV has a clear line of sight from the router. Walls, kitchen microwaves, mirrors, baby monitors, and devices emitting radio signals can block network signals. Adjust the router’s external antenna and remove any appliance that could cause signal interference.
We highlight ways to boost a weak Wi-Fi signal in this article. Go through it for more network troubleshooting tips. If nothing works, shut down the router or unplug it from its power source. Turn it back on after a minute or two and try connecting your Apple TV to the network again.
2. Forget Other Network(s)
Do this if your Apple TV won’t connect to your preferred Wi-Fi network. Or if the device keeps joining an undesired network with no internet connection. Forget the problematic network and connect to your preferred network.
Open the Settings app, select Network, select Wi-Fi, select the tricky network and select Forget Network.
If your Apple TV still doesn’t join the Wi-Fi connection, there are probably too many devices on the network. It’s also possible that the network admin has blocked your Apple TV from joining the network. Contact the network admin or check the next section to learn how to unblock your Apple TV in your router’s settings menu.
3. Check Your Router Settings
Many wireless routers have security measures that block devices from using wireless internet connections. For example, your Apple TV won’t connect to Wi-Fi if it’s under a MAC Address Restriction or Filter.
If you have access to the router’s admin panel, head to the device management section, and check if your Apple TV has permission to access the network. Whitelist your Apple TV or remove it from any restriction.
It’s a good idea to have your Apple TV’s MAC address handy in case your router indexes devices by their MAC address.
Go to Settings > General > About and note the characters in the Wi-Fi Address row.
This guide on whitelisting specific devices on your home network has detailed instructions. Better yet, refer to the router’s instruction manual or visit the manufacturer’s website.
4. Restart Your Apple TV
Power-cycling the streaming device can resolve temporary system glitches preventing it from connecting or staying connected to Wi-Fi and Ethernet networks. Unplug your Apple TV from the power outlet and plug it back in.
Alternatively, go to Settings > System and select Restart.
To restart older Apple TV models (3rd generation Apple TV or earlier), go to Settings > General and select Restart.
5. Reset Your Wi-Fi Router
If no device can join the network, resetting your router’s settings to factory default is the next best thing to do. Read our guide on resetting wireless routers or refer to your router’s instruction manual for device-specific instructions.
6. Update Your Apple TV
Your Apple TV may drop Wi-Fi connections or fail to join wireless networks if its operating system is outdated or contains bugs. Of course, installing tvOS updates requires an internet connection. But since your Apple TV won’t connect to Wi-Fi, you have two alternatives: use an Ethernet connection or perform a computer-based factory reset.
Plug an Ethernet cable to the Apple TV, go to Settings > System > Software Update, and select Update Software to download and install the latest tvOS version on your Apple TV.
To update 3rd generation Apple TVs, go to Settings > General > Software Updates and select Update Software.
If you don’t have an Ethernet connection, you can remotely update the Apple TV using your Mac or Windows computer by performing a factory reset. That will remove your accounts and delete all settings, configurations, and third-party apps. But on the positive side, the operation will download and install the latest tvOS version on your Apple TV. Likewise, it’ll remove bugs and software conflicts stopping your Apple TV from establishing a Wi-Fi connection.
After trying all the troubleshooting steps listed above, you should only perform a factory reset if your Apple TV won’t connect to Wi-Fi.
Note: If your Apple TV lacks a USB port, contact Apple TV Support or visit a nearby Genius Bar to have your device fixed or restored to factory default.
- Disconnect the power and HDMI cables from your Apple TV. Connect each end of the micro-USB or USB-C port to your computer and your Apple TV.
- If you’re using a Mac, launch Finder and select your Apple TV in the sidebar, and select Restore in the device menu.
- On a Windows PC, launch the iTunes app, select your Apple TV in the upper-left corner (next to the Music drop-down menu), and select Restore Apple TV.
- Wait for Finder or iTunes to download and install the tvOS update and disconnect your Apple TV only when you get the “Your Apple TV has been restored to factory settings” success message.
Connect a power and HDMI cable, hook the device to your TV, and set up the Apple TV from scratch.
7. Reset Your Apple TV Settings
This option restores your Apple TV settings to factory default without updating the device.
Go to Settings > System > Reset and select Reset.
Wait until the reset is complete (it takes a couple of minutes), set up the Apple TV, and try connecting it to a Wi-Fi network.
Contact Apple TV Support
Call the Apple contact phone number assigned to your country/region, make a Genius Bar reservation, or chat with an Apple Support agent if you still can’t get your Apple TV to connect to Wi-Fi.
