How to download using mobile data instead of Wi-Fi
The Waiting for Wi-Fi message shows when your device is set to use Wi-Fi for downloading but a Wi-Fi connection isn't available.
To download using your mobile network instead of Wi-Fi:
From the Waiting for Wi-Fi message, select Download Settings or Download Now.
If prompted to Always allow downloads over cellular on an Android device, select Allow.
Toggle the switch next to Wi-Fi Only to turn the setting off.
The download won't begin immediately. To begin, tap the Downloads icon then Download.
To download when Wi-Fi is available again instead of using your mobile network, select Cancel or OK.
The Wi-Fi Only setting can be changed at any time:
Open the Netflix app.
In the lower right, tap My Netflix.
In the upper right, tap the Menu.
Tap App Settings.
Under Downloads, turn the switch next to Wi-Fi Only on or off.
Note: You won't be able to change this setting if you have pending downloads. If your preferred data setting is grayed out, cancel all pending downloads or wait for them to finish, then try again.
