How to confront a manager that he doesn't know how anything works

I work for an ISP and As the title suggests, I'm dealing with a manager who has no idea about networking (not even what an IP/MAC is).

How he got into his position? A friend of the owner

Surely, he has no idea about any of the incoming requests (yet he'll keep nagging for it)

If someone mentions that today's latency to the internet is 1ms higher than yesterday he'll wear his detective hat and go into micro-management since he assumes it is a big deal.
