networking - Wireless not working on HP15q-bu005tu 16.04 - tried all available solutions

I have a new HP15Q-BU00TU laptop that came with free DOS. I have installed Windows 8. The wireless connection on Windows works fine.

Here is the result of lspci:

Here is the result of lshw, that shows an unclaimed Wireless network:

I installed Realtek driver from the Realtek website, no luck yet.

I have read through all possible solutions and have tried all of them.

I gather from another post that d723 is not yet supported by Linux. Is this true?
