I have found that 99% of all network problems are bad wires.
I remember that the IT guys at my old company, used to immediately throw out every ethernet cable, and replace them with ones right out of the bag; first thing.
But these ships tend to be houses of cards. They are not taken care of properly, and run on a shoestring budget. Many of them look like floating wrecks.
- jmonty900 1y agoI recently had a home network outage. The last thing I tested was the in-wall wiring because I just didn't think that would be the cause. It was. Wiring fails!
- nrhrjrjrjtntbt 1y agoOh yeah had outages recently. Turned out to be corroded connector to box in the street. Not a wire per-se but close.
- HeyLaughingBoy 1y agoI remember a customer support call where the hardware they bought from us wasn't working. The last question I asked was "are you sure that the outlet it's plugged into is working?" It wasn't.

- gerdesj 1y agoIf I see a RJ45 plug with a broken locking thingie, or bare wires (not just bare copper - any internal wire), I chop the plug off. If I come across a CATx (solid core) cable being used as a really long patch lead then I lose my shit or perhaps get a backbox and face plate and modules out along with a POST tool. I don't look after floating fires.

- esafak 1y agoThen you kill the visual signal; that the cable might have been yanked and potentially loose.
- yabones 1y agoChopping the plug is a very good idea, everybody should practice that. I once had a recurring problem with patch cables between workstations and drops going bad, four or five in one area that had never had that failure rate before. Turns out, every time I replaced one somebody else would grab the "perfectly good" patch cable from the trash can beside my desk. God knows why people felt compelled to do that when they already had perfectly good wires, maybe they thought because it was a different colour it would make their PC faster... So, now every time I throw out a cable that I know to be defective, I always pop the ends off. No more "mystery" problems.
- bell-cot 1y agoI'd be so tempted to find a source for shiny-looking Cat 3 (10Mbit/sec) patch cables, and start seeding my trash can with those...
- potato3732842 1y agoIf I had a nickle for every time someone clobbered some critical connectivity with an ill-advised switch configuration I wouldn't have to work for a living. And the physical layer issues I do see are related to ham fisted people doing unrelated work in the cage. Actual failures are pretty damn rare.
- leoedin 1y agoThat's true for almost all electronics. I worked on robotic arms for a few years - if things broke it was always the wiring (well, to be precise - the connectors).
