mobile

I could really use some help/advice on this one.. I have been searching xda and google for ages trying every "trick" there is but nothing works. My phone is the Note 3 Sm-N900(exynos)

My problem is that my wifi simply won't start:/ Now let me give you the history of this problem

I was on KitKat and my wifi wasn't working and I was pretty sure it is a hardware problem. I wanted to factory reset it and get it fixed somewhere.
I saw android lollipop and thought oh well if I am resetting everything I might as well flash android 5.0 (russian version)
I did that and baam, WiFi was back! That led me to think that it was just some software issue after all and I was damn happy.

I instantly rooted and installed trwp (made a backup) as I always do.
On the next day, wifi stopped working again, I restored the backup and everything back to normal with working wifi.

Then I decided to install the new cyanogenmod alpha version. Wifi still working fine only sd card wasn't recognized for which I downloaded the fix which is available in the cyanogen thread.
After installing the fix wifi was gone again.

I restored my backup I had made after upgrading to lollipop but now WiFi still isn't working. Is it a hardware problem after all?

That's about it. If you need any logs or any additional information please let me know.

Thanks very much in advance!:)
