Linux Elementary OS Constantly WiFi Dropping

Question

Two days ago, I installed Elementary OS on my ASUS K550L. Everything looks just perfect, but since first hour of exploring the system, my WiFi connection keeps dropping every several minutes.

I checked and restarted my router, but no solution. After searching the internet for solution, I got THIS, but there is a part with editing text file:

gksu gedit /etc/pm/config.d/unload_modules

and there is an error message popping out when I try to save the file, saying that the file does not exist.

I'm really loving this distro, but as I'm new to Linux, I can't seem to find a good solution for this problem.

Also, in some posts I saw people update their question with

sudo lshw -C network

so, mine is here:

This happends only when I connect to my router, and the internet is fine when connecting on my mobile hotspot

Any solutions? Thank you for your time, hope somebody can help!

Solution

I searched a little more, and found out this solution, which worked perfectly!

Since I had a Realtek wireless card 3290, I found the solution here: LINK

The first one example,

NOT OFFICIAL DRIVERS FOR Kernel 4.X

This solved my problems! Hope this post will help others too.
