I also have Asus ROG STRIX Z370-E GAMING motherboard with wireless card built in but running Ubuntu 18.04. I tried chili555 answer in post:

Asus Rog Strix Z370 EGAMING Wireless card not working

I do not have enough reputation to comment their, also my post is a bit long. When I ran make I was warned that 

Makefile:976: "Cannot use CONFIG_STACK_VALIDATION=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel"

So I tried this

sudo apt install libelf-dev
make clean
make

which seemed to work

..
..
Install rtlwifi SUCCESS

however the last line gave an error:

sudo modprobe rtl8822be
# modprobe: ERROR: could not insert 'rtl8822be': Exec format error

[edit]

@Jeremy31

$ modinfo rtl8823be | egrep -i 'file|vermagic'
modinfo: ERROR: Module rtl8823be not found.

$ modinfo 8823be | egrep -i 'file|vermagic'

Open Software & Updates from the start menu. Go to the Additional Drivers tab. There you will find the options to select your Wi-Fi and Graphics drivers. It will look like the image in the following link: https://ibb.co/gWd3yU

You may select the options I've selected. Then press Apply Changes. And hopefully, you are done.
