BBB & latest Debian on eMMC Wifi broken after reboot

I’ve decided to put the BBB to use as a home media server instead of leaving my pc on all the time. I put the latest Debian flashable image on a microSD, held down the button, installed the image on the flash, removed the microSD, plugged in the wifi usb module. Got it working, updated the OS but the wifi stops on a reboot. I have to manually bring it up by: ifup wlan0
Adafruit has a tutorial at: but it’s a no go because uEnv.txt is not there anymore.
