Atheros R9285 wireless card unstable and weak reception

So I finally installed the arch,
Everythings going well except for the wifi, which disconnects every minutes now and then. It disconnects whenever I try to a download a package it will give a timeout because of low speed.

I have read some topics on forums and it turned up my wifi card is under 'ath9k' drivers. I saw this post which leads to a bug fix, but that kernel version is way before my kernel version which is 4.4.19-1. I have also tried to install backports-patched from AUR but I came up with errors.

Another thing good to notice is that when I run 'netrunner rolling' (arch distro I've installed) live iso wifi works great!

Here are some output:

Re: Atheros R9285 wireless card unstable and weak reception

As I said before in live iso I have no problem. I tought this might be network manager tool. So I installed Wicd, it shows better reception (only 'shows' apparently), but connection gets disconnected.
Also when I installed Netrunner Rolling setup said that there were no device driver found for my wifi card(or something like that).
And another thing I tried was dmesg | grep firmware and that gives nothing back, which I suppose mean that there's no need to install firmware(?).

BTW: would installing 'backports' solve my problem?

Still waiting for some response,
Thanks.
