We need to have a category like that here. For example I've learned ASUS AX53U supports beamforming, but from inside the terminal. That's why it's so good. Also there is bunch of terms like QAM or some shiny stuff. How do I know that my router supports all that? So I could buy accordingly. I really like the openwrt lately, I want the best for it.
For example I wanna buy a ASUS RT-AX59U in the future, maybe. But I will be paying a lot of money for that, since I pay that a lot, I want to see if all works right.
