No internet after few seconds with Realtek LAN Driver (and WAN) on zen

This started quite recently, where internet connection just drops, and if I check on Networks, it's connected and fine (except that UP/DL are zero), and in order to get the internet connection back, I must click on "disconnect" and on "connect" again, then it'll work for X time and stop.
With the WAN adapter it's even worse, because it basically cannot connect to the internet, it does find and connect with WIFI but doesn't work! Even if I use my phone's hotspot these issues still happen.

I always used Linux-zen kernel, and I assume the driver always were the r8169, and for now, at least on LAN, the only way to make it work is to 'yay -S r8125-dkms' (while r8169 is blacklisted), but if I restart my PC all the issues are back, even if it's reported that linux is using r8125 driver, and as you guess it, to get it working I must again install r8125-dkms driver.

Can anyone shine a light on this? Or maybe the only way out is trying Linux kernel?
