I got a network switch that is showing zero activity across about a dozen ports, the most important of which is the feed from the router from upstairs. This happened out of nowhere and I don’t think it’s the switch unless the backup I tried is also bad. I also tested the cable leading from the router and it passes the continuity test at the very least. Even if that line was dead, wouldn’t the switch show at least SOME activity as devices try to access each other? I’m no IT master, but peer to peer still happens in a network, doesn’t it? Anyway, it’s been a few days of trying to fix this myself, so I finally turn to reddit. Any ideas, lads?
Network doesn’t have to be “so fucked” for there to be a loop. It’s an incredibly easy mistake to make.
It’s just that there’s only one switch really. There’s definitely wires I forgot where they go, but in this case I don’t think it’s a loop simply because nothing changed when it went out.
