Awesome tech, if (and only if) you control it end to end, with no corporation involved in that process.
That's why you buy your own router.
I'm using chromecast for streaming to my television. But I accidentally cut my internetcord and guess what doesn't work without internet eventhough it doesn't strictly need internet? Exactly, I'm getting rid of the chromecast soon.
When streaming content to a chromecast it usually makes a direct connection to the content source, not going through the device you're casting from. In limited cases like when sharing your screen to the chromecast it does only go from your device to the chromecast without internet, but that's rarely used because it's power and data intensive to your device. I guess you're right on the internet not being 'strictly' needed but it's used for a reason.
Should still buy your own router though, and move away from google services ๐
Yeah "google bad" but this isn't one of those instances. They've been very upfront about the functionality of the Chromecast for a very long time

When you can. Depending on the country and ISP, using your own router isn't always feasible unless sacrifying most of your bandwidth
Your telling me a streaming device doesn't work without internet. I'm shocked shocked I fell you.
It should be able to work on lan as well, in my opinion
Are you trying to cast or screen share? Screen share should work over LAN I think.
Screenshare does work over lan, according to the documentation, but the chromecast doesn't even start up properly. It onky says (full screen) there is no internet connection.
