Before Wi-Fi became ubiquitous, Ethernet was the preferred method for connecting devices to the internet. By running Ethernet cables within a local area network (LAN) or wide area network (WAN), you can send data faster and more securely than with wireless alternatives.

Ethernet's history dates back to 1973 when it was invented by Xerox Palo Alto Research Center engineers, Robert Metcalfe and David Boggs. The standard has since evolved from 10 Mbps in the early days to today’s capabilities of 40 Gbps for home use.

Fast Ethernet (1995) and Gigabit Ethernet (1999) paved the way for higher speeds, making Ethernet a clear choice for organizations that prioritize high speed, security, and reliability. Even with Wi-Fi's advancements, Ethernet still offers stable latency and consistent throughput, free from interference common in shared wireless networks.

The type of cable you choose is crucial. Cat 5e or Cat 6 cables are suitable for most home needs, while Cat 6a can handle up to 10 Gbps speeds. More advanced Cat 7a and Cat 8 cables may be overkill but offer higher bandwidths if needed. Proper installation and protection from damage will ensure optimal performance.
