The 'good bits' of OSX is that there is no such a thing as 'drivers' from the users perspective.
Well, unless you buy some hardware that is not from Apple. Buy a 802.11ac USB stick (because your Mac has 802.11n and you cannot upgrade the hardware) with Mac drivers. The vendor decides to release a (buggy) driver update for El Capitan half a year after it's released.
Pretending that the driver problem does not exist on macOS does not make it go away.
