We recently pickup a few customers that needed it security (malware, antivirus, and firewall). After we finish setting this up, customer ask us if we can look into why they have computers constantly loosing network connectivity. After a bit of troubleshooting, we realize the cables were bad. We ended up replacing come cables (Cat 5e plenum). After we removed the old cables and replace with new one, we were curious, what could possible be wrong with cables, as in our experience cables rarely go bad. After inspecting the cable, we did a quick burn test. We found out the cable was not 100% pure copper. In the last 5 years, we have ran into more and more of these scenarios. Our guess was that in the last decade, there have been a major price increases on copper due to demands from China, have force some vendor to purchase cheaper quality cables. If you have computers that are constantly loosing network connectivity, give us a call, we can help!
