How does Chromecast work and why does it need WiFi?
Chromecast is a media streaming device that Turn any TV with an HDMI port into a smart entertainment centerYou can send content from your phone, tablet, or computer directly to the big screen with just a few taps. To do this, Chromecast requires both it and the transmitting device to be connected to the same Wi-Fi network. However, this doesn't mean you always have to rely on your home router.
The reason Chromecast needs WiFi is because its streaming technology, based on the Google Cast protocol (which combines Miracast and DLNA), relies on wireless connectivity to communicate with other devices. Additionally, many advanced features, such as voice control with the Google Assistant or access to streaming services, require the internet.
What happens if you don't have WiFi access? The good news is that there are ways to overcome this need, such as by making Chromecast "think" it's connected to a Wi-Fi network even if it's connected to your smartphone's cellular data, or even by using other connections or special modes.
Everything you need to use Chromecast without WiFi
Before you begin, make sure you have on hand:
- A Chromecast device (any version).
- An Android phone or tablet, or an iPhone/iPad with mobile data.
- The Google Home app installed on the device you'll use to set up and manage Chromecast.
- The exact details (name and password) of the last WiFi network to which you connected your Chromecast. It's essential for some methods, especially if you're going to "repeat" the Wi-Fi network from your mobile.
- A TV with an HDMI port and, if you're using the Ethernet connection (optional), the corresponding adapter.
Additionally, it's highly recommended that you have a generous data plan if you plan to stream content, as intensive usage can quickly deplete the available megabytes in your plan.
Using Chromecast without Wi-Fi on Android: Step by Step
If you have an Android phone, you can create a shared connection (WiFi Zone or Hotspot) to act as a substitute for your home network. This method is ideal for traveling, second homes, hotel rooms, or anywhere you don't have access to a traditional router. Here are all the details to make sure nothing goes wrong:
- Access the Settings from your Android mobile and enter the section Network and Internet (The name may vary depending on the brand: look for something like “WiFi Zone”, “Tethering” or “Hotspot”).
- Within the menu, select Portable WiFi zone o WiFi access pointIf you can't find the option, use the Settings search engine.
- edit the name (SSID) and password from your access point so that they are exactly the same to the usual Wi-Fi network the Chromecast was connected to. Don't change a single letter, number, or symbol.
- Activate the WiFi hotspot from your mobile.
If your Chromecast has already been set up, when you turn it on, it will detect the "fake" Wi-Fi network provided by your phone and automatically connect, thinking it's your home network. This way, you can cast content to it from any device connected to that same hotspot.
Important: Keep in mind that everything you send to the Chromecast will consume mobile data on the smartphone that's acting as a hotspot. It's essential to monitor your usage, especially if you're going to stream high-quality videos.
Additionally, if you need to set up Chromecast from scratch, it's recommended to do so with a second phone (with the Google Home app) to minimize connection interruptions.
Alternative method: two mobiles for maximum stability
In situations where you want to avoid interruptions or set up a Chromecast on a new network, this procedure with two phones ensures a completely stable experience.
- 1 mobile: Create and activate the Portable Wi-Fi Hotspot as explained above, using the same name and password as the previous network.
- 2 mobile: Connect it to the network created by Mobile 1 and install Google Home.
- Open the Google Home app on Mobile 2, press the button + and choose Configure device → Set up new device.
- Follow the steps to select the Chromecast, confirm the code on the TV, and select the Wi-Fi network (Mobile 1's hotspot).
- After setup, you can use only Mobile 1 for the hotspot and cast content from any connected device.
This method is especially useful if you're having trouble with the initial setup or want to make sure apps don't consume extra data during the process.
Use Chromecast without Wi-Fi with iPhone or iPad
On iOS, the process is very similar to that of Android, but there is one peculiarity: You cannot manually change the access point name, since by default it takes the name of the iPhone itself. The detailed procedure is as follows:
- Accede to Settings> General> Information and click on it name of your iPhone.
- Change the name to exactly the same as the Wi-Fi network the Chromecast is configured to. It's essential to respect uppercase, lowercase, and special characters.
- Return to the main Settings menu and enter Share internet o Personal Hotspot (name varies depending on iOS version).
- Choose WiFi password and write it the same as your previous Chromecast WiFi network.
- Activate the option Allow others to connect o Share internet.
- Confirm that Wi-Fi sharing is enabled if prompted by iOS. That's it!
When you turn on the Chromecast, it will search for your usual Wi-Fi network, and since the iPhone Hotspot now has that name and password, it will connect automatically. Anything you send to the Chromecast from a connected device will use mobile data from your plan.
Important: Some models require mobile data to be enabled to enable hotspot. If you see the option blocked, check this setting.
Workaround: Use Chromecast with a Windows or Mac computer
You can also create a local network from your PC or Mac if you don't have a mobile phone to generate the hotspot. This method is useful for sharing screens, sending local files, and giving presentations without relying on the Internet (but does not allow access to online streaming services if there is no Internet access on the computer).
In Windows:
- Accesses Control Panel > Network and Sharing Center.
- Choose Set up a new connection or network > Set up an ad hoc wireless network.
- Enter the same name and password than your Chromecast's regular WiFi network.
- Connect from your mobile phone or tablet to the created network.
- Open Google Home and, from there, connect the Chromecast to that local network.
Remember that you can only view or send files that are already stored; services that require internet access won't work if your PC isn't connected to the internet.
On Mac:
- Go to Apple menu > System Preferences > Sharing.
- Create a new shared WiFi network, assigning the same name and password as the Chromecast network.
- Connect your phone/tablet to that network and use the Google Home feature to link the Chromecast.
Alternatively, you can share your computer screen with Chromecast using Chrome: click the three dots (top right), select "Cast," and choose the available Chromecast.
What is Chromecast Guest Mode? A Wi-Fi-free alternative
Guest Mode is a specific feature available on some "standard" Chromecast models (not Chromecast Ultra or Chromecast with Google TV) that allows you to send content without having to be on the same WiFi network. Ideal for situations where you want to share content with friends without giving them access to your home network.
How to activate it:
- Open the Google Home app and select your Chromecast.
- Access the settings menu and enter Recognition and sharing → Guest mode.
- Activate Guest Mode. An access PIN will be generated.
Nearby devices that want to cast content simply select the Chromecast in their app and, if prompted, enter the Guest PIN. Your phone must be connected to the internet (mobile data or external Wi-Fi), but the Chromecast doesn't need to be on the same Wi-Fi network!
Chromecast with Ethernet: stable connection without WiFi
On supported Chromecast models, you can connect the device using a Ethernet adapter (Google and several third parties sell accessories with an Ethernet port) allowing for a direct and more stable connection, ideal for those who suffer from wireless signal interruptions, areas with interference or want to take advantage of the best streaming quality (for example, for 4K or online gaming). More information on alternatives to using WiFi.
Installation is simple:
- Connect the Ethernet adapter to the Chromecast and to power.
- Insert the Ethernet network cable from your router, repeater, or network switch.
- Set up your Chromecast normally on Google Home. If it detects an Ethernet connection, it will prefer it over Wi-Fi.
This solution is especially useful in offices, rooms far from the main router, or if you have access to a wired network without Wi-Fi.
