Wi-Fi & Touchpad ASUS TUF F15 FX506HM

I am very new to Linux and Ubuntu. I have been a Windows user all my life, and now, I want to switch to Linux as I hope to become a better programmer. I just got a job as a placement software developer and got a brand new laptop, ASUS TUF F15 FX506HM, and I installed Ubuntu from a flash drive. Unfortunately, I can't seem to make my Wi-Fi connection work. Whenever I am entering the Wi-Fi settings I can see that an adapter is not found. I tried multiple tutorials and forums before asking this question here, but what can I do to make my Wi-Fi work?

By running a couple commands found on different tutorials I came to the conclusion that my wireless interface is not recognized for some reason. I tried checking the bios, but there was not luck. Below are the commands run and the output.

I know that Linux requires skill, that I do not have yet. Also, my touch pad is not working, do not know why... Could you please help and guide me with the wireless interface problem? Also, a guide to surely install all drivers needed and updates would come in handy. Thank you very much for your time and help, it is very much appreciated!

====== Wi-Fi SOLVED ======

The link chili555 gave was very useful. If the solution in the link provided by him does not work from the first try, completely remove ubuntu and any other data from your computer and install again 21.04, it works even with 20.04. I do not know why it did not work the first time I tried, but reinstalling was not the solution. I had to completely erase the disk, and then install again. Although it did not solve the touch pad problem. Thank you very much chili555! You were really helpful.

Today, all of a sudden, the touchpad started to work for me under Arch Linux. Try updating your system.

Libinput identifies the touchpad as:

Device:           ELAN1203:00 04F3:307A Touchpad
Kernel:           /dev/input/event258
Group:            8
Seat:             seat0, default
Size:             101x52mm
Capabilities:     pointer gesture
Tap-to-click:     disabled
Tap-and-drag:     enabled
Tap drag lock:    disabled
Left-handed:      disabled
Nat.scrolling:    disabled
Middle emulation: n/a
Calibration:      n/a
Scroll methods:   *two-finger edge 
Click methods:    none
Disable-w-typing: enabled
Accel profiles:   flat *adaptive
Rotation:         n/a

And XInput identifies it as:

⎜   ↳ ELAN1203:00 04F3:307A Mouse               id=15   [slave  pointer  (2)]
⎜   ↳ ELAN1203:00 04F3:307A Touchpad            id=16   [slave  pointer  (2)]

Info about the kernel:
