Cat5. The old stuff that people ran classic 10Mbps #Ethernet over. These cables are museum pieces.
Wikipedia says most #Cat5 cables already happen to meet #Cat5e specs, though. https://en.wikipedia.org/wiki/Cat5e#Variants_and_comparisons
About 10 years ago, I was doing everything in #Cat6, figuring there'd be some amazing new ∞Gbps standard that would require it…and then 10GBaseT came along and was like “nah 5e is fine lol” and then 40GBaseT was all “lul cat6 is for noobs.”
So that was a total f***ing waste of money. 😂
