Ethernet is commonly used as shorthand for Gigabit Ethernet, a standard that supports network speeds of up to 1Gbps. Faster 2.5Gb, 5Gb, and 10Gb Ethernet is now available with some mesh routers. These can handle speeds up to 2.5, 5, or even 10Gbps respectively.  Although quicker, better Ethernet standards are not useful for most people. Few Internet service providers can deliver service speeds above 1Gbps. The enhanced speed is still useful for transferring files over your local network, which might matter if you have a home file server.
