loki 0.4.1 wifi dropping/bad signal problem possible solution

Hi everyone! so i installed elementary os yesterday (loki 0.4.1, kernel 4.10*) as i'm sick of win and what it does to my life :P Everything works for me exept wifi dropping constantly and when connected signal was without any bars (rly bad) so i googled a bit.
My laptop is HP Pavilion g6 with RT5390 Wireless 802.11n 1T/1R PCIe adapter.

note: this should work for other laptop models too!

Solution i found is to update to newest kernel from here

Now in detail, you find out what your os architecture is (32 or 64 bit in system settings>about next to OS version below logo), than enter top folder on this website above (newest kernel version number) and look for a section related to your OS (amd64 - 64bit OS / i386 - 32bit OS).
Three files you need have specific words in name:
*headers*_all.deb
*headers*generic*.deb
*image*generic*.deb

so this is what i did for 64bit OS. Open terminal (super + T. Super key = Windows key) and download those three packages in temp folder with these two lines:

$ cd /tmp
$ wget \
kernel.ubuntu.com/~kernel-ppa/mainline/v4.13-rc4/linux-headers-4.13.0-041300rc4_4.13.0-041300rc4.201708062231_all.deb \
kernel.ubuntu.com/~kernel-ppa/mainline/v4.13-rc4/linux-headers-4.13.0-041300rc4-generic_4.13.0-041300rc4.201708062231_amd64.deb \
kernel.ubuntu.com/~kernel-ppa/mainline/v4.13-rc4/linux-image-4.13.0-041300rc4-generic_4.13.0-041300rc4.201708062231_amd64.deb

note: right click on file links on that site, copy link adress and remove

http://

than you install them with:

$ sudo dpkg -i linux-headers-4.13*.deb linux-image-4.13*.deb

and if you want to remove them later:

$ sudo apt-get remove linux-headers-4.13* linux-image-4.13*

Related link is here.

After that just reboot and voila. You can check it in system settings>about.

Hope this helps someone.
Cheers!
