I’ve always thought this is due to Wi-Fi Assist [0] being less than helpful? Never tested any further though

I don't think that is the problem, just something that kicks in after the problem has happened and wifi has disappeared. Eg, on my macbook, I was loosing wifi every hour before I tweaked the settings on the router.
