Hi,

I recently bought a laptop: HP ProBook 450 G8. It came with default installation of Windows 10, under which its wifi connects and works fine. I however, installed Slackware-64 v15-current, and wifi is not recognized either by Network Manager, or by wicd. Following is the output from wireless-info.
