You have to be specific about the hardware you buy. Throughout my time I've bought around 2 or 2 routers with the naive assumption "oh it will probably work out fine", and that's definitely not how it works. That has certainly left me with disappointment. IME it pays off greatly to upfront research the specific model (and revision) and buy exactly that. Like in this case, the Archer C7 v2 (of which I've recently bought two). It's running OpenWrt flawlessly and I would have zero issues recommending that particular model to anyone.
