@kerosene Just noting that Wi-Fi usually encapsulates Ethernet packets and its packet format is similar to Ethernet.

1000BASE-T is indeed faster than Wi-Fi mind you.

Wi-Fi cables are indeed a thing - you can do 802.11 signalling encapsulated in Ethernet over 1000BASE-T and you can also get an excellent signal for testing purposes by screwing a antenna extension wire between two wireless AP's rather than antennas.
