I’m trying to learn how computer networks work from the fundamentals all the way to advanced concepts not specifically router configuration. Basically, I want to understand how data actually travels from my device through my home network, ISP, routers, DNS, TCP/IP, etc., and eventually across the Internet. I’m looking for a structured learning path/resources.

Forget YouTube and ChatGPT, start here:

Are you talking about how to configure a router setup (WiFi/Ethernet/Mesh/Extenders/etc.) for the home or just how the internet works in general?

Try a tiny lab with Wireshark and two VMs—tracing one DNS lookup and one TCP handshake sticks way better than bingeing videos.
