No, 40 meters is sufficient for running a CAT6a Ethernet cable.
No, 40 meters is sufficient for running a CAT6a Ethernet cable.
You're considering a CAT6a or CAT5e connection between your router and Nvidia Shield. The 30 to 40 meter range is generally acceptable for Ethernet, especially with repeaters if needed. CAT6a tends to be more expensive than CAT5e, but the difference isn't always drastic depending on your specific setup and requirements.
They wouldn't feel confident about that picture. Cat 6 supports 10Gbps over distances up to 55 meters, Cat 6a extends that to the full 100-meter Ethernet standard, while Cat 7 isn't even a TIA-approved standard and uses various connectors compared to the others—definitely not worth placing alongside the other TIA Cat standards.
