Try the CCNA course of CISCO, “The Complete Network Fundamentals”. I did one of those years ago. It’s a great course to achieve a good base of networking. CCNA is just the first step to a good introduction, if you like it, you can expand your knowledge with more.

Me too. Took it in classroom from a Cisco partner when i was a junior webdev 20 years ago and not exposed to any network equipment. instructor was a network admin at big Co and made us crimp ethernet Jacks and shared a Lot of stuff between the lines. most of things i learned there still applies in my daily job as Solution arch

I did the CCNA course in high school, and it's where I learned how to troubleshoot. It has served me well beyond the scope of networking.
