what wlan driver to use on a 3 yr.old Pi3B?

[wa5qjh]

Sorry, I know this must be 10 steps backwards for most of you.
I just downloaded and burned to SDHC the new RPi3 12.2-Release and was so happy to see it "wake up"! but I have been trying for hours to get wifi up on it. I even resorted to plugging in 2 external wifi dongles, neither one of which i ever made work. but at least i found rtwn drivers in /boot/kernel. i know the wifi function is woven into the bluetooth controller, but I saw no fathomable (by me) connection to a driver. 
 I need help, Please. direct answers as to the driver name, links to places to read, whatever anybody is willing to share!
