如果您没有智能电视，Google Chromecast为您提供了一种在电视上访问在线内容的替代方式。

这个方便的小设备通过 HDMI 连接到您的电视，^{(hooks up to your TV via HDMI)}并使用WiFi将内容从您的手机投射到电视或显示器上。但这还不是全部，您还可以使用 Chromecast 做许多其他很酷的事情，^{(cool things you can do with a Chromecast)}包括玩游戏和制作演示文稿。

但是，如果您的WiFi信号较弱、参差不齐，或者您离无线互联网的来源^{(source of wireless internet)}很远，您将无法使用Chromecast设备投射您的内容。幸运的是，有一些替代方法可以让您在没有WiFi的情况下使用^(WiFi)Chromecast。

如何在没有 WiFi 的情况下使用 Chromecast^{(How to Use Chromecast Without WiFi)}

您可以使用 Chromecast将您喜爱的内容从手机投射到电视^{(cast your favorite content from your phone to your TV)}，而无需正常的WiFi设置，方法是：

• Google Home 应用中的访客模式
• 以太网连接
• 便携式/旅行路由器
• 您智能手机的热点

如何通过访客模式在没有 WiFi 的情况下使用 Chromecast^{(How to Use Chromecast Without WiFi Via Guest Mode)}

访客模式^{(Guest Mode)}是Chromecast中的一项功能，最初旨在让您家中的访客连接到您的Chromecast设备并投射内容，而无需连接到您的WiFi。该功能为您提供了一种无需WiFi连接即可轻松连接到Chromecast设备的方法。

较新的 Chromecast^{(Newer Chromecast)}型号可以传输WiFi和蓝牙^(Bluetooth)信号，通过短而听不见的音频来广播PIN 。这样，任何尝试投射到设备但未在您的WiFi网络上注册的人都可以使用PIN将内容从他们的设备连接并流式传输到Chromecast。

1. 要在Chromecast上使用访客模式^{(Guest Mode)}，第一步是在您的设备上启用访客模式。^{(Guest Mode)}为此，请打开Google Home 应用^{(Google Home app)}并点按您的 Chromecast^{(name of your Chromecast)}设备的名称。

1. 接下来，点击屏幕右上角的设置（齿轮图标）。^(Settings)

1. 在设备设置^{(Device Settings)}屏幕中，向下滚动并找到访客模式^{(Guest Mode)}。如果您没有看到访客模式^{(Guest Mode)}，则您的Chromecast设备没有该功能。

1. 如果访客模式^{(Guest Mode)}列在 Chromecast 的设备设置^{(Device Settings)}中，请检查其下方是否显示PIN 。这表示该设置已启用，您可以继续正常投射内容。如果您在访客模式^{(Guest Mode)}设置下方看不到PIN，这意味着您可以在访客模式下^{(Guest Mode)}投射，但该设置已被禁用。在这种情况下，点击访客模式^{(Guest Mode)}，然后将开关切换到开^(On)。

1. 等待它生成 PIN^{(generate a PIN)}，然后转到您要从中流式传输内容的应用程序并进行投射。

通过 Google Cast-ready 应用程序在没有 WiFi 的情况下使用 Chromecast^{(Use Chromecast Without WiFi from a Google Cast-ready App)}

如果您没有访客模式^{(Guest Mode)}，您可以随时从支持Google Cast 的应用进行投射，享受您喜爱的内容，而无需担心WiFi。

1. 为此，请将您的 Chromecast 固件更新到最新版本，否则没有WiFi将无法工作。
2. 接下来，在您的设备上打开支持 Google Cast 的应用^{(Google Cast-ready app)}，然后点击Cast按钮。 

1. 您会在电视上看到一个 4位数的 PIN^{(digit PIN)}，您将在Chromecast应用程序中输入该 PIN 以连接您的手机和电视或您用来投射内容的任何设备。例如，如果您使用 YouTube，请点击Cast按钮，然后点击Link with TV Code。 

1. 连接设备后，您现在可以将内容从主设备投射到连接到Chromecast的屏幕上。

使用以太网连接^{(Using an Ethernet Connection)}

在没有WiFi的情况下使用Chromecast的另一种方法是连接以太网^(Ethernet)电缆。

如果您正在旅行，您唯一的选择是本地WiFi热点或酒店互联网，这种方法很有帮助。在这种情况下，在您访问WiFi之前，需要使用浏览器功能以及接受某些条款和条件^(WiFi)的双重身份验证^{(two-factor authentication)}。

Chromecast没有浏览器功能，因此您将无法流式传输内容。但是，通过以太网^(Ethernet)连接，您可以连接到互联网并从您的设备投射到Chromecast。

要使此方法起作用，您需要一根以太网^(Ethernet)电缆，另一端带有USB连接。如果您使用的是Chromecast Ultra，请将以太网^(Ethernet)电缆插入以太网^(Ethernet)电源适配器，然后将USB电缆连接到Chromecast。完成后，插入活动的以太网^(Ethernet)插孔并像往常一样投射内容。^(Once)

注意^(Note)：如果您有新的Android-TV驱动的Chromecast，它不支持以太网^(Ethernet)，但您可以为此购买特殊的电源和以太网适配器^{(power and Ethernet adapter)}。较旧的Chromecast型号不包含以太网^(Ethernet)电源适配器，但您可以购买第三方适配器，例如Cable Matters 微型 USB 转以太网适配器^{(Cable Matters micro USB to Ethernet adapter)}或UGREEN 以太网适配器^{(UGREEN Ethernet adapter)}。

How to Use Chromecast with a Travel/Portable Router

如果您没有WiFi并且想要将内容投射到您的Chromecast设备，便携式或旅行路由器是一个很好的选择。此外，与本地WiFi^(WiFi)热点或酒店WiFi相比，使用自己的路由器更安全，因为您拥有更多隐私，可以控制谁可以访问您的网络^{(control over who can access your network)}，并且您无需接受公共WiFi协议。

要使用此方法，您需要先设置路由器，为其分配 SSID^{(assign it an SSID)}（网络名称）和密码，然后通过设备上的Chromecast应用程序将您的Chromecast连接到路由器。

如果您住在酒店，请将路由器连接到以太网^(Ethernet)连接，并将另一端连接到电源插座，这样在您享受喜爱的内容时它就不会熄灭。您可能需要使用酒店电视的设置菜单来选择您的路由器并输入密码。

注意^(Note)：如果您没有看到路由器，请通过设备的网络设置手动输入SSID和密码。连接后，电视将通过Chromecast^(Chromecast)应用程序列为流媒体目的地，您可以从设备流式传输内容。

使用智能手机的热点^{(Use Your Smartphone’s Hotspot)}

如果您无法使用我们迄今为止介绍的任何方法，您仍然可以使用智能手机的热点^{(use your smartphone’s hotspot)}在没有WiFi的情况下在^(WiFi)Chromecast上投射内容。 

为此，您需要在智能手机上启用热点选项，以便它可以用作路由器。但是，您需要第二台设备才能加入网络并连接到您的Chromecast。

如何通过第三方服务在没有 WiFi 的情况下使用 Chromecast^{(How to Use a Chromecast Without WiFi Via a Third-Party Service)}

第三方服务是在没有WiFi的情况下使用 Chromecast 的不错选择，尤其是在您拥有 iPhone、Mac或其他方法不适合您的情况下。

用于此目的的最佳应用程序之一是Connectify Hotspot，它允许您将计算机的WiFi或有线互联网连接共享为WLAN（无线局域网）热点位置。

1. 要使用Connectify Hotspot，请将应用程序下载到您的计算机并进行设置。打开软件并输入热点的名称和密码。
2. 选择WiFi 热点^{(WiFi Hotspot)}选项，将您要投射的设备连接到网络，它将显示为您投射的流媒体目的地。 
3. 在Chromecast^(Chromecast)应用程序上选择设备并将本地存储的内容流式传输到电视。

在没有 WiFi 的情况下设置 Chromecast^{(Set Up Chromecast Without WiFi)}

无论您是在旅行还是由于某种原因无法访问WiFi，有很多选项可以提供无线互联网连接，这样您就可以继续享受您喜爱的内容。

如果您在使用Chromecast设备时遇到问题，请查看我们关于如何重置 Chromecast^{(how to reset a Chromecast)}的指南。

How to Use a Chromecast Without WiFi

If you dоn’t have a ѕmart TV, Google Chromecast offers an alternative way for you to access online content on a TV.

The handy little device hooks up to your TV via HDMI and uses WiFi to cast content from your phone to a TV or monitor. But that’s not all, there are many other cool things you can do with a Chromecast including playing games and making presentations.

However, if your WiFi is weak, spotty, or you’re nowhere close to a source of wireless internet, you won’t be able to use your Chromecast device to cast your content. Fortunately, there are some alternative ways you can use Chromecast without WiFi.

How to Use Chromecast Without WiFi

You can use Chromecast to cast your favorite content from your phone to your TV without a normal WiFi setup by using:

• Guest Mode in Google Home app
• An Ethernet connection
• A portable/travel router
• Your smartphone’s hotspot

How to Use Chromecast Without WiFi Via Guest Mode

Guest Mode is a feature in Chromecast that was originally intended for guests in your home to connect to your Chromecast device and cast content, without connecting to your WiFi.  The feature offers an easy way for you to connect to your Chromecast device without a WiFi connection.

Newer Chromecast models can transmit a WiFi and Bluetooth signal that broadcasts a PIN via short inaudible audio tones. This way, anyone who tries to cast to the device but isn’t registered on your WiFi network can use the PIN to connect and stream content from their device to Chromecast.

1. To use Guest Mode on Chromecast, the first step is to enable Guest Mode on your device. To do this, open Google Home app and tap the name of your Chromecast device.

1. Next, tap Settings (gear icon) at the upper right corner of your screen.

1. In the Device Settings screen, scroll down and find Guest Mode. If you don’t see Guest Mode, then your Chromecast device doesn’t have the feature.

1. If Guest Mode is listed in your Chromecast’s Device Settings, check whether there’s a PIN displayed underneath it. This indicates that the setting is already enabled, and you can proceed to cast content normally. If you don’t see a PIN underneath the Guest Mode setting, it means you can cast in Guest Mode but the setting has been disabled. In this case, tap Guest Mode and then toggle the switch to On.

1. Wait for it to generate a PIN and then go to the app you want to stream content from and cast it.

Use Chromecast Without WiFi from a Google Cast-ready App

If you don’t have Guest Mode, you can always cast from a Google Cast-ready app and enjoy your favorite content without worrying about WiFi.

1. To do this, update your Chromecast’s firmware to the latest version, otherwise it won’t work without WiFi.
2. Next, open a Google Cast-ready app on your device, and then tap the Cast button. 

1. You’ll see a 4-digit PIN on your TV, which you’ll enter into the Chromecast app to connect your phone and TV or whichever devices you’re using to cast content. For example, if you use YouTube, tap on the Cast button and then tap Link with TV Code. 

1. With the devices connected, you can now cast your content from your primary device to the screen that’s connected to the Chromecast.

Using an Ethernet Connection

Another way to use Chromecast without WiFi is by connecting an Ethernet cable.

This method is helpful where your only options are local WiFi hotspots or hotel internet if you’re traveling. In such cases, two-factor authentication, which uses browser functionality plus acceptance of certain terms and conditions, is required before you can access the WiFi.

Chromecast doesn’t have browser functionality so you won’t be able to stream content. With an Ethernet connection, however, you can connect to the internet and cast from your device to Chromecast.

For this method to work, you’ll need an Ethernet cable with a USB connection on the other end. If you’re using Chromecast Ultra, plug in the Ethernet cable into the Ethernet power adapter, and then connect the USB cable to the Chromecast. Once done, plug into the active Ethernet jack and cast content as you normally would.

Note: If you have the new Android-TV powered Chromecast, it lacks Ethernet support but you can buy a special power and Ethernet adapter for that purpose. The Ethernet power adapter isn’t included with older Chromecast models, but you can buy a third-party adapter like the Cable Matters micro USB to Ethernet adapter or UGREEN Ethernet adapter.

How to Use Chromecast with a Travel/Portable Router

A portable or travel router is a great alternative if you don’t have WiFi and want to cast content to your Chromecast device. Plus, it’s safer to use your own router compared to a local WiFi hotspot or hotel WiFi as you have more privacy, control over who can access your network, and you there are no public WiFi agreements to accept.

To use this method, you need to set up the router first, assign it an SSID (network name) and password, and then connect your Chromecast to the router via the Chromecast app on your device.

If you’re staying in a hotel, connect the router to the Ethernet connection and connect the other end to a power outlet so it doesn’t go off while you’re enjoying your favorite content. You may need to use the hotel TV’s settings menu to choose your router and enter the password.

Note: If you don’t see the router, enter the SSID and password manually through the device’s network settings. Once connected, the TV will be listed as a streaming destination via Chromecast app, and you can stream content from your device.

Use Your Smartphone’s Hotspot

If you can’t use any of the methods we’ve covered so far, you can still use your smartphone’s hotspot to cast content on Chromecast without WiFi. 

To do this, you’ll need to enable the hotspot option on your smartphone so it can serve as the router. However, you’ll need a second device to join the network and connect to your Chromecast.

How to Use a Chromecast Without WiFi Via a Third-Party Service

A third-party service is a good alternative to use a Chromecast without WiFi especially if you have an iPhone, Mac, or the other methods aren’t working for you.

One of the best apps for this purpose is Connectify Hotspot, which allows you to share your computer’s WiFi or wired internet connection as a WLAN (wireless local area network) hotspot location.

1. To use Connectify Hotspot, download the app to your computer and set it up. Open the software and enter a name and password for the hotspot.
2. Select the WiFi Hotspot option, connect the device you want to cast to the network, and it will appear as a streaming destination for you to cast. 
3. Select the device on the Chromecast app as well and stream your locally stored content to your TV.

Set Up Chromecast Without WiFi

Whether you’re traveling or can’t access WiFi for some reason, there are plenty of options that can provide a wireless internet connection so you can continue enjoying your favorite content.
