Claimed for Ethernet 6a cable. The 6a ethernet cable contains a shield and a 4-way separator to prevent interference. However, these connectors stack the pins close together in the connector body, making the 6a look more like a 6. Also, the connectors are capped at the end so there is no way to push the pins through the connector to ensure each pin fits properly and is in place. I'm pretty sure this caused an arc in my connection because I couldn't see where the pins actually sat. I had intermittent outages with my router and this caused one of my network switches to stop working. I'm pretty sure there is a grounding issue with these plugs as the wall plug to this newtwork switch is no longer generating enough current to operate the switch. It took 2 days for these plugs to destroy my home network that had been working flawlessly for years! The manufacturer has no shame!
