#22How does one learn about this stuff? I learned about basic networking in college (the TCP layers) etc but people doing such stuff sounds like Greek to me. If I want to learn more about what the author is doing, is there a resource like a udemy course or YouTube channel you guys can recommend?
The vagueries of DHCP can be learned best with a home lab, IMO
Back in the day, setting up random hardware or VMs on an isolated subnet taught you everything you needed to know about low level network protocols like DHCP, STP, BOOTP, ARP, RARP, and how to sniff it all with wire shark when you weren’t getting a lease
Containers have largely hidden this plumbing from us at a test/dev layer

Don't know about video courses, but Internet standards like DHCP are open and available on IETF.org. There are explanations on Wikipedia too. Also, if you're into Linux the HOWTO section on tldp.org can also be a big help for more practical stuff.

Would need to know which vendor. I used to work for a company that provided satellite Internet solutions for airplanes but might not be what OP used

#25I love that “internet reset” button
Should be labeled "Turn Internet off and on again".

Back in the day you needed to know this stuff to get things working. It was not that uncommon for routers not to have DHCP so you had to input the IPs by hand. I think this may have been even the default and DHCP had to be explicitly enabled (e.g. in Linux installing and configuring dhclient).
Also it wasn't that uncommon to expose a computer to internet through the router, so you had to make sure that computer didn't change its IP.
I think having to set these up yourself is the best way of learning them.
Re: I told the flight attendant "the WiFi isn't working"
#27This reminds me of a conference, attendees were having sporadic problems with accessing the Internet and eventually I was able to capture a trace of the problem: when the main lease network filled up, it started allocating IPs from another block, but with the same gateway. I got a lease for something like 10.1.1.69/24 with a gateway address of 192.168.1.1.
I went to the support person and she offered to reset the WiFi, but I explained that she needed to escalate it because it was a configuration problem, resetting it was only a temporary solution.

Most computer networks 101 class teach how their state machine is designed only.
If you want to know "how to use them in real world", some universities has courses with "System Administration" would be more suitable. or learning the certificate program (CCNP, CCIE, JNCIP and others) materials with their lab.

#29Deep in the granite mountain where the internet Kill Switch is located, there is also the US national Internet Reset switch. What exactly, in this fictional universe, is the restoration flow if it is pressed?

I'd suggest a book. I was pretty happy with "Computer Networking: A Top-down Approach" by Jim Kurose. I find it more appealing that it starts with the upper layers (http), because I was more familiar with them.
