Is USB-C connection the same as Thunderbolt 2? Will this adapter allow a macbook pro from early 2015 to use ethernet?

    A USB-C connector is just the connector. USB-C does not describe the signals that are passed on the connector.

    A USB-C connector can provide any combination of the following:
    power source (for charging)
    power sink (for being charged)
    USB 1.1/2.0 (low speed 1.1 Mbps, full speed 12 Mbps, high speed 480 Mbps)
    USB 3.0 / USB 3.1 gen 1 (super speed 5 Gbps)
    USB 3.1 gen 2 (super speed+ 10 Gbps)
    Thunderbolt 3 (Thunderbolt 1 10 Gbps, Thunderbolt 2 20 Gbps, Thunderbolt 3 40 Gbps)
    DisplayPort 1.2
    DisplayPort 1.3/1.4
    HDMI 1.4

    A port that can do Thunderbolt 3 should also be able to do Thunderbolt 1, Thunderbolt 2, USB 1.0/2.0/3.0/USB 3.1 gen 2, DisplayPort 1.2, and HDMI 1.4 using various adapters. Other adapters can then provide Ethernet, VGA, audio, etc.

    The Belkin USB-C to Gigabit Ethernet Adapter can be used with current MacBook (USB-C) and iMac / MacBook Pro 2016 and later (Thunderbolt 3) computers.

    For the MacBook Pro 2015, use the Apple Thunderbolt to Gigabit Ethernet adapter instead. There's also the Apple USB Ethernet Adapter but that only works at up to 100 Mbps. The Apple Thunderbolt to Gigabit Ethernet adapter can be used with Thunderbolt 3 computers using the Apple Thunderbolt 3 to Thunderbolt 2 adapter.

  • The connection is not the same. Apple do still sell a thunderbolt 2 Ethernet adapter though, so that’s you’re best bet.
