Just a thought - this may or may not be related to router's MU-MIMO implementation (or lack thereof), as the main difference in wireless connectivity between a macbook and everything else is that recent macbooks have 3x3 MU-MIMO while other devices have 2x2 or even 1x1.
I'd bet your macbook is fine Yeah, there's a slim chance that something's borked in drivers or wireless module itself But it's way more common for no-name routers to be, well, shite then for macbooks to randomly crash routers
