Would that explain why the connection only succeeds rarely, or why it worked consistently (at least for the remainder of the evening) when I restarted my router?
I am at a loss. What I know is that the WD driver writes log information when it starts. If that log info isn't there then almost certainly the driver isn't running correctly.

I opened calibre in debug mode again, started wireless device connection, attempted to connect twice (with no success), stopped wireless device connection, started it again, and let it sit for a little bit (just in case the wireless driver is slow to start, as you mentioned) before trying to connect again (still no success), before stopping wireless device connection and closing the debug version of calibre. The debug log didn't seem to contain those SMART_DEV lines that are supposed to be there.
I waited for approximately 8 minutes before attempting to connect, should I give it more time for the WD driver to start?
No. If it doesn't start in 8 minutes then it won't ever start.

Should I reset my router again (which should hopefully give another successful connection) and provide a debug log of that?
It might be that I am focusing on a non-problem. I don't have a Mac and therefore cannot see what a "normal" Mac log looks like. That said, I also cannot see any reason why the SD driver log messages would be thrown away.

Putting aside the log problem, it is possible that the problem is in the router. In particular, if the router supports "guest mode" or "wireless isolation" then it will block connections between devices on the local network. That blockage would explain why the CC default settings don't work and why connections fail. In this case the mystery becomes "why does it ever work?" The router shouldn't turn these features on and off by itself.

One thing you can do is try using the content server. That lets us remove CC from the scenario. You would turn on calibre's content server (you might have already have done so) then attempt to connect from your device using its web browser instead of CC. The URL would look something like http://192.168.1.102/. If this doesn't connect then we know that the problem is not CC but is instead somewhere on your network. If it does connect then try doing a content server connect from CC (you might need to enter the IP address). If this fails then we know that the problem has something to do with CC. If it works but wireless device connections do not work then we know that the problem is in calibre or on the calibre computer.

Then I tried uninstalling the Marvin and iOS plugins, but only the iOS one could be disabled - it said that disabling the Marvin XD plugin was not allowed. When I opened calibre, it said that Marvin XD plugin requires the iOS plugin, so they might have both been disabled...?
I don't use either so I can't give definitive answers. It is possible that you might need to uninstall the plugins one at a time, restarting between the uninstalls.

If I do upgrade my calibre version, as it seems like the next step may be, how would I go about downgrading back to this one? I'd like to make sure I know how to do that, if it comes to it.
You get the install file for the version you have from the calibre-ebooks site. If you need to downgrade you uninstall the current version then install the previous version. Again, as I don't have a Mac I can't be more precise.
