Cannot find wlan0 wifi dongle

Question

I have tried multiple tutorials on how to setup wifi on my Raspberry Pi 2 but none have worked. New to Linux, hoping someone can help.

When I highlight my network connection in the toolbar I see enxb827ebd72440:: Configured wlx9cefd5fcb786: not associated

I have run

sudo apt-get update
sudo apt-get upgrade
sudo apt-get autoremove
sudo reboot

I tried downloading the RT5370 driver but when I try to "make" it I get

Follow the steps in the tutorial, but use the correct interface name of your Wi-Fi card wlx9cefd5fcb786 instead of wlan0. If you still have some problems let us know. — oh.dae.su, Mar 27 at 18:46
You've enabled predictable network interface names (or is that now the default?) - disable using raspi-config and go to Network Options=>Network Interface Names and select No - exit out of raspi-config, reboot, and done — Jaromanda X, Mar 28 at 1:07
I have disabled predictable network interfaces and now I no longer see wlx9cefd5fcb786 in ifconfig or iwconfig and I tried changing etc/network/interfaces to use that instead of wlan0 but that completely disabled my internet connection, including wired ethernet auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlx9cefd5fcb786 auto wlx9cefd5fcb786 iface wlx9cefd5fcb786 inet dhcp — Cryptanimator, Mar 28 at 18:48

I ended up just reinstalling raspbian with the dongle plugged in, now it works great
