What would cause this cat cable problem

Very strange. Cat cable from Flex6K directly into my router (My router has both shack computers and xyl's computer connected. A switch is also connected that feeds other devices around the house. ie portables, laptops, cameras, etc.)
The other day I saw that I only had one teeny green bar being displayed on the SSDR screen.
Mousing over displayed that I had many many dropped packets.
Fortunately I had an extra cable and replaced the existing cable. That immediately corrected the problem and SSDR screen returned to full connection as displayed by the Network indicator.

This cable had been in use since I received the F6K.

Just wondering if anyone ever had such a problem and any idea what caused it?

The cable gave up to the tortures of the increased capabilities of V1.4. Actually Ethernet cables fail for multiple reasons; bad crimps on the connectors which after time allow for less than full contact between the wires and the pins, too much tension against the connector due to cable routing, etc.

Assuming that this was not a "home-made" cable, it's likely a manufacturing issue. Best to use cables with strain relief boots from a quality manufacturer.

Sometime, they just give out after a while. Cables flex, connectors get strained. Just a tiny flaw can do it.
