How to change Chromecast WiFi network?


If you have two WiFi networks at home for different purposes, for example, one for normal usage, and the other connecting to a VPN server, you may sometimes want to switch  Chromecast WiFi network.

This tutorial will show you how to change  Chromecast WiFi network  if you have more than one WiFi network at home.

Please note, this tutorial assumes you can access both WiFi networks. If you no longer have the access to the old network, you have to reset your Chromecast as shown in this tutorial.

Chromecast can only remember one network at any time. Changing Chromecast WiFi network means that the old network info will be deleted from Chromecast device.

Chromecast can only access 2.4GHz WiFi network. But your mobile devices or PCs that are on 5GHZ  network or on Ethernet can still find and connect to this Chromecast device,  as long as your devices and Chromecast are connecting to the same router.

To switch or change Chromecast WiFi network, you need:

  • 2 or more WiFi networks in the same location (otherwise, why switch?)
  • your mobile devices can access both networks
  • Chromecast can access both  WiFi networks (2.4G only)
  • mobile devices with Chromecast app installed

In this tutorial, we will use an Android  device  (iPhone or iPad works in the similar way). The Chromecast WiFi network will be changed from “dlink24g” to “tplink24g” .

Step 0: Power on Chromecast

To change Chromecast WiFi network, Chromecast must be on and connected to a WiFi network.

If you do not want to watch the changes on TV (you can always see it on your mobile devices), you do NOT need to power on the TV.

Step 1: Start Chromecast App on mobile device

To manage the WiFi network for Chromecast devices from a mobile device, you have to start Chromecast App in your mobile device.

Once the  Chromecast App is started, your mobile device will search for any Chromecast devices in the same network in range.

The discovered Chromecast devices will be listed once the search is over as shown below.


Step 2: Connect mobile device to Chromecast

In the devices page,  tap the Chromecast device  to connect the mobile device to this Chromecast device.



When your mobile device is connected to (paired with)  the Chromecast device, the detailed information of this Chromecast setup will be shown as below:


Now, the device is connected to dlink24G.

Step 3:  Change Chromecast WiFi network

To change Chromecast WiFi network, simply tap the network entry as shown above. This will brings a popup window showing current network info.


Tap the current WiFi network info as shown above, you will get the list of WiFi networks in range (discovered by your Chromecast device).


Tap on the new  WiFi network you want to use.

Provide the password for that WiFi network.

Tap OK to change Chromecast WiFi network.


Now you will get a warning message. It tells you that if you tap OK, your Chormecast device and your mobile device will be not in the same network. The Chromecast App on your mobile device will automatically switch your mobile device’s WiFi network to the same network as Chromecast. In other words, your mobile device will change WiFi network automatically after you change Chromecast WiFi network.

Of course, if the password of the new network is not saved in your mobile devices, the connection will fail.

You can also manually change the WiFi network in your mobile device. Please check the user manual of your device.



After tapping OK, the Chromecast device will try to connect to the new WiFi network. Now you finish to change the Chromecast WiFi network.


Step 4: Connect your Mobile device to the network

If both of your mobile device and Chromecast connect to the new network successfully, you will be able to find in the devices page as shown below.


This means you successfully changed Chromecast WiFi network. You can now stream contents to your TV from this new network.

    The device worked until we installed u-verse recently, but I can’t change inputs. When I try, I’m prompted to open the chrome cast app.. This starts the connection process with no options except “continue” and “cancel” The only option results in another long fruitless search for the device which is plugged in and blinking, but inoperative.. Is there any other way to change inputs?

    I changed ISPs from Comcast to Frontier, updated Chromecast settings (wifi ID and password) but it does not connect. It says “Something went wrong” and to check to network settings and try again. I’ve checked and double check the wifi id and password. Still no luck…any ideas?
