I disagree. It's possible to get advanced output from various command line tools in Linux, and it's possible to get networking information. It's much more difficult to do that on other OSs, especially Windows. I loathe debugging network troubles in Windows, because there is essentially no information. OS X has most of your standard tools, though some in some odd places, e.g., printing the routing table not being done with `route`.

Furthermore, I care. My 2013 Macbook Pro is terribly slow to associate to even nearby APs, and drops the connection often. I have no idea why, because it is opaque: how do you list nearby APs? their signal strength or encryption type? I didn't learn this until just now, and it's,

    /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport -s

Seriously. There's no way I'll remember it, and if you're reaching for it, you likely can't Google it. And it appears to be deprecated. It's a much shorter command in Linux, and in general I find it easier to determine if the problem is the network connection or DHCP failure. IIRC, Network Manager's icon changes — admittedly not much – depending on which one it's on, so even without command line tools, I have some idea what's going on.

OS X has the troubleshooter dialog, but that's never been able to fix the problem. (In general, I feel, those things never do. They also never tell you what they're doing. For all I know, they're just progress bars and timers.) WiFi off, WiFi on fixes a lot of problems.
