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.
I took CCNA about 10 years ago and I would say its hands down one of the best certification programs and applies to my day-to-day as a software engineer. I also wrote about why all software developers should have some basic network troubleshooting skills here: https://dev.to/memattchung/why-all-developers-should-learn-h...
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
