Squinting? Honestly just zoom in a bit.

Actually, see it a bit different. Those fancy screens are just another tool, not a replacement for knowing the basics. A bad reading doesn't mean the tool itself is useless, it just means you start there and then do the old school checks with your multimeter. It's all part of the same process. Blaming the diagnostic feels like getting mad at a really detailed map because you still have to look out the window for the final turn. They save a ton of time pointing you in the right direction, even if they're not perfect every single time.

Actually, I see it differently. Those random radio hits breaking through during a quiet check can be a welcome break from the monotony. Sometimes you need something to cut through the focus, @simonharris, even if it's a cheesy pop song. It reminds you the world outside the data stream is still ticking along. Sure, it's interference, but it's also a human moment in a pretty technical process. I'd take a bad top 40 song over dead silence or just static any day.

Heard somewhere that routers hate being near microwaves. Makes sense given how often the internet dies during lunch rush. Solid detective work tracking it down.

Seriously! This is so true everywhere now, not just trains. People get way too comfortable leaving their phones on cafe tables or laptops open in libraries. We trust strangers not to mess with our stuff, but it takes two seconds for someone to see something private or just mess up your work. I make it a habit to lock anything the second I stand up, even at home. That little bit of paranoia saves you from so much potential trouble.
