In other words, is it possible to Googlecast from wi-fi to Ethernet (on the same network, of course)? I want to send my wi-fi notebook Windows desktop to a wired Nvidia Shield, which has Google Cast built in. So far Chrome on the notebook fails to see the Shield. Since I have no idea what I am doing, it is probably my fault.

Hi thanks, I've seen those links. I don't have a phone but I do have another Android tablet. Your idea is a good one. I will dig out the tablet tomorrow and see what I can find out.

Do you have some "security" feature on your network that prevents devices seeing each other perhaps? This is common in some wireless networks.

I finally got this to work. As usual, the problem was just my own ignorance.

Now for the next step. I can cast the desktop with no problem, and I can see everything on the site, but as soon as I try to play any video, the screen goes blank and I get some Shield symbol in the middle, with a wi-fi symbol as part of that. When I leave the video, the normal display returns.

I assume this is some copy protection BS, but then what is the point of casting in the first place? I thought the whole purpose was to be able to display something on a big screen that is already on a small screen. Can anyone offer enlightenment about this? The site I am trying to cast in my experiment is Medici.TV.

As an aside that I just can't resist adding, the content industry really needs to get real. If I want to make a high quality copy of anything, I can easily do it. There are so many ways of copying content these days that the only thing copying restrictions accomplish is pissing off legitimate users. No-one needs copies of anything anyway. Those days are behind us.

Edit to add: I answered my original question. There is no problem casting to a wired Shield from a notebook on wi-fi.

Second edit: I could just delete this but it has been standing awhile so I will add another comment instead. It turns out that Medici is the one responsible. They restrict casting to premium subscribers, of which I am not yet one, so there is a reasonable explanation for this.

when you cast it stop playback on the device you are casting from and just plays on the device you casted to. ie i cast a video from youtube on my phone to my TV it will stop playing on my phone and just play on the TV. i can still control it from my phone but cant watch it.

if you are just casting a tab in chrome/desktop some sites have copy protection on them which prevents the content being cast.

That is what I thought when I posted my complaint but Medici does this to restrict access to Premium subscribers. I don't have a problem with that, especially as they also give some free stuff away. I think it is legitimate to say you have to be a Premium subscriber to do this. I can still play the content, I just can't cast it. Fair enough.

Sorry, it had to do with Windows settings. I'm not sure exactly what. I was fiddling with different network and sharing settings (Win 10) and I suddenly saw it was working. I don't know exactly what made the difference, but I must have had something switched off that it needed. My networking skills are pretty minimal.

Fully agree with regards to silly copy protections. Flatmate owns a plasma tv that doesn't have HDCP support. You can't use it to watch legally purchased movies in HD. Yet pirated movies play perfectly fine in HD.

That TV also rubs it in, as it displays a popup window whenever the resolution of the video source changes.

The devices need to be on the same LAN segment. So if your Wifi is on a different subnet to your LAN then it won't work. If you're using an all in one router with Wifi it should work no problems.

Also things like firewall software can cause issues.
