I am on a Dell laptop, that came stock w Win 10, and my miracast is broken. (It worked since the beginning, then broke one day.)
I initially thought (per How to troubleshoot miracast on windows 10 laptop? ) that a windows update caused the issue. I now think the installation of the Sonicwall VPN Netextender client caused the problem. (And, fwiw, I have both Sonicwall Netextender AND Cisco Anyconnect vpn clients, I use them both. I had anyconnect for some months with no miracast problem, but when I put on Netextender....)
There are documented conflicts between Miracast and some vpn clients ( http://digitalmediaphile.com/index.php/2015/04/24/trouble-shooting-miracast/ and other threads)
But I have tried uninstalling Netextender and rebooting, and miracast did not come back to life (and I need Netextender!).
How do I:
a) Get logging data out of miracast on the laptop to help diag the issue?
or
b) "Walk" the networking stack to (hopefully) identify what is messing w Miracast
or
c) ___ ?
UPDATE
I found a solution to the problem here: https://superuser.com/a/1328168/15466
