Chromecast generally requires a Wi-Fi connection to function. Here's a breakdown:
Why Wi-Fi is Typically Needed
- Content Streaming: Chromecast streams content from the internet (e.g., Netflix, YouTube). This requires a Wi-Fi connection to access the internet.
- Casting from Devices: Your smartphone, tablet, or computer needs to be on the same Wi-Fi network as the Chromecast to "cast" content to the TV.
Alternatives to Wi-Fi (Limited)
While Wi-Fi is the primary method, there are a few limited alternatives:
- Ethernet Adapter: Google sells an Ethernet adapter for Chromecast. This allows you to connect Chromecast directly to your router via Ethernet cable, bypassing Wi-Fi.
- Mobile Hotspot: You can use your smartphone's mobile hotspot to provide a Wi-Fi connection to the Chromecast, but this will use your mobile data.
In Summary
For most users and typical use cases, Chromecast needs Wi-Fi. The alternatives are less convenient or have limitations.
