How to set up a Chromecast without WiFi

The first thing to say is that by default Chromecast requires to be connected to the same Wi-Fi network as our smartphone in order to receive content on TV. What happens then if we do not have a router at home, the Internet is down or the wifi does not work? The good thing is that, fortunately, we can establish a small safe-conduct, and that is precisely what we will see in this small tutorial.

How to use a Chromecast without being connected to a Wi-Fi network

In essence, the trick is to "trick" the Chromecast device into thinking it is connected to a Wi-Fi. We do not need to have any router or anything similar installed at home: it is enough that we have our phone at hand and an extra smartphone to carry out the trick in question.

1- Create an point access with your mobile

The first thing we will do is pick up that additional phone number that we are commenting on and share the connection creating a Wi-Fi hotspot.

. We open the settings menu of our Android mobile.
. We go to “Networks and Internet -> Wi-Fi Zone / Connection Connection”.
. Click on "Wi-Fi access point" and activate the connection tab (by default it appears in "Disabled").
. We write down the name of the access point and the password on a paper or notebook.

In this way, we will have a Wi-Fi network to which we can connect the Chromecast for the first time and make the necessary settings on the device.

2- Initial Chromecast Settings

The second thing we will do is pick up our mobile (the one we will use to send content to Chromecast) and install the Google Home app. This app is absolutely essential, as it is the tool we will use to communicate with the Chromecast for the first time.

nce installed, we connect our mobile to the access point we just created in the previous step with the other phone. Then, we connect the Chromecast to the TV and open the Google Home app.

. In the lower menu, we go to the “Account” settings
. Select "Configure or add -> Configure device -> New devices".
. The system will automatically search for Chromecast and try to establish a connection.

When it is detected, it will be added to our list of Google Home devices.

After performing this initial configuration, we can proceed to deactivate the Wi-Fi access point, since we will not need it anymore.

3- Connect the mobile to Chromecast

This last point is where the magic begins. One of the features of Chromecast is that if it detects the Wi-Fi network with which it was initially configured, the device automatically connects to that wireless network.

What we are going to do is take advantage of this detail to fool the Chromecast and think that it is connecting to the same access point that we have configured at the beginning of the tutorial.

To do this, we take the mobile that we will use to send content to the TV and create a new access point. Of course, it is very important that we use the same name and password set in the previous smartphone (which we should have noted on a paper) for this new access point.

In this way, Chromecast will detect the Wi-Fi network and automatically connect to our mobile. From here, we only have to enter YouTube to send any video, or share the screen, photos, music and other mobile content so that they play on Chromecast without problems.
