Hi, yes, your pretty much right for the most part. I'm not sure you read the thread. My answer to the recipient was ONLY to make this point. All cables are not created equal. I wasn't making the case for gold contacts, etc., I was only refuting a previous responder that told him, "pretty much, a cable is a cable, any should work, just pick a color", yada, yada, yada
Ok, if your point is that "Any cable should work," then understand that the different versions of Category cable over the years are rated to do different things. The older Cat 3 cables you have are rated for 10BASE-T Ethernet, Token Ring, and 100BASE-T4 speeds.
Newer methods of manufacturing allowed for faster speeds, which led to the higher numbered Cat versions, which Cat 5e and 6 are most common. Both are able to reach gigabit ethernet speeds which is common in most of the network adapters sold in computers today.
So not just any cable will do. Your older cable, wile venerable, just will not match newer cables on modern networks. Cat 3 may do in a pinch if needed, and you may not notice the difference if your internet speed falls under what it Cat 3 is rated for, but beyond that, it is inferior to the newer standards, including the features I previously listed.
