Sending audio/video to projector wireless without connecting the projector to Wifi
Posted on 2016-08-31
I have a customer with a special problem. They have very tight security in the wifi network, nothing gets on it without installed certificate. This rules out wifi-connected devices as printers, projectors and items like Miracast.
They would still like to send audio/video to a projector - while maintaining internet connection on the laptop.
I they could live without internet it would be easy as pie to connect a Miracast with an ad-hoc connection. But that is not what they want.
So I have as I can see it at least two choices, but do not know if either will work:
1. Use two different wifi connections at the same time (could be possible with an extra wifi-dongle, but have never tried). That is, the native wifi connected to the internet wifi, the second one as an ad-hoc to a Miracast.
2. Use a different solution all together, but I have found no good alternative.
To make it even more complicated, there will be a lot of different laptops connecting to the projector, and not all of them have HDMI out. And that is also why no software installation is acceptable. It should work with no hardware/software installation, on at least Win 8 and 10. If using a hardware to send a/v to the projector there have to be at least HDMI and VGA(plus sound) inputs, preferably connecting to a wireless HDMI only reciever.
