Miracast Issues

[Rigmarole]

We have a new business requirement, whereby [ideally] we'd like to have our windows tablets be able to WIN+K (Miracast) to some Samsung/LG TVs around our properties and offices.

This has never really worked, and we've never paid much attention to it, but need to start.

TVs are on the same wifi network / subnet as the client computers. Air Marshall is off (which I've heard can be an issue). We seemingly have no wireless access or L7 policies blocking this. I'm a bit stumped.

Wifi is bridged to the L2, no client isolation policies (that I can see).

I appreciate Miracast isn't the 'best' technology out there, and googling definitely confirms that. But ideally I'd rather not invest in some totally different technology if possible.

Any ideas?

How about deny local lan setting?

While I am not familiar with this, another forum suggests checking (verifying) Miracast functionality and if it is enabled as a preliminary step and secondary would be to make sure it's running the latest available firmware.

From your post I'm guessing that the TVs are wired and the tablets are using wireless.  Is that correct?  If so, have you tried connecting a TV wirelessly to the same SSID as the tablets?

I have a wonderful issue where I have a wireless printer and a wireless laptop. 

• If they are connected to the same SSID with the same subnet then it works
• If they are connected to different SSIDs with different SSIDs then it works
• If they are connected to different SSIDs with the same subnet, no wireless printing...
