Unpopular opinion: A Bangkok internet cafe during a rain delay changed my diagnostic style
I got stuck in Bangkok last year when a monsoon flooded the airport. To wait it out, I found a crowded internet cafe where the owner was fixing computers. He had like twenty machines all hooked up to one shaky router, and instead of panicking, he just went from PC to PC checking each one's network config. It was slow, but he found the one device hogging bandwidth. Back home, I used to just replace network cards first thing when internet was slow. Now, I mimic his method and start with the simplest checks, like ping tests and cable inspections. It saves clients money and often fixes the real problem. That rainy day taught me that patience in chaos beats rushing to conclusions every time.
