I had often issues with multiple Realtek wifi chips on Linux years ago and researched a bit. Apparently, they just reiterate their prior generation with patched-on features. And not only in software but in hardware too, to flood the market with cheap chips. To make it working smoothly on Windows, they use dangerous hacks in the driver, which Linux has not.
So this is still the case? I don't buy Realtek anymore and look closely on components.
