      Periodically stops working physical connection loose

      This dongle stuff is not reliable over time. On my 2015 MBP, the lightning connector for this adapter is loose in both ports. I will be running web meetings This dongle stuff is not reliable over time. On my 2015 MBP, the lightning connector for this adapter is loose in both ports. I will be running web meetings and if my laptop shifts or I bump the cable, the network disconnects, killing my meeting. It's really frustrating to have spent $2,000, then $30 for this connector and have unreliable Internet. I don't know if the flaw is with the adapter or laptop ports, or both. Just ridiculous to have this problem. I was better off with tech in the 1990s, then I plugged in network cable and it never failed.

      Stops working

      I had it for a 2-3 years. I used it 30-40 times and stopped working. This is the second connector from Apple that behaves this way. I used to have one to get I had it for a 2-3 years. I used it 30-40 times and stopped working. This is the second connector from Apple that behaves this way. I used to have one to get an HDMI connection (before it became standard in the MacBookPro), which I used 10 times before it quit. No buying these expensive gadgets from Apple anymore.

      This doesn't work in El Capitan when using high speed 1000BaseT gigabit eth

      In a Macbook pro Retina Late 2013 with OSX 10.11.4, it doesn't support gigabit ethernet. It works fine with 100baseTX but it doesn't work with 1000BaseT.

      Great little adapter for a decent price

      I would highly recommend this little dongle over the USB Ethernet adapter for MacBook Airs and older Pros and iMacs. It's the same price as the USB adapter at $ I would highly recommend this little dongle over the USB Ethernet adapter for MacBook Airs and older Pros and iMacs. It's the same price as the USB adapter at $29.00, but it supports Gigabit Ethernet (10/100/1000 Mbps) speeds, which is way faster than the 10/100 Mbps max that the USB adapter has. I know a lot of people complain that the Thunderbolt to Gb Ethernet doesn't last long, but I can imagine that it was really designed with the iMac in mind.

      WORKS GREAT!

      The internet speed is PERFECT for what I need it to do. Mine seems to be working fine, although the reviews say that it does wear out. Hopefully mine won't!!!!

    • Is this Thunderbolt 3?

      Answer

      No, it's Thunderbolt 2. In order to use it with a Thunderbolt 3 port, you'd need a Thunderbolt-3-to No, it's Thunderbolt 2. In order to use it with a Thunderbolt 3 port, you'd need a Thunderbolt-3-to-Thunderbolt-2 adapter. There's one on the store... search for "Thunderbolt 3 USB-C to Thunderbolt 2 Adapter" As unwieldy (and expensive) as chaining two adapters together may seem, at the time of this writing, it's probably the most reliable way to have a highly-portable, high-performance, reliable Ethernet connection. Any other USB-C dongle-style adapter available today will add its Ethernet port via the Type-C port's USB 3 channel, not the Thunderbolt channel. This makes the adapter much more prone to issues with reliability, driver compatibility, heat, and CPU usage. If something less portable is an option for you, I'd recommend using a Thunderbolt 3 dock to add an Ethernet port, since it would use the Thunderbolt channel, giving you better reliability and performance. I've used one by CalDigit with no issues, and Apple sells one by Belkin here on the store... search for "Belkin Thunderbolt 3 Express Dock HD"
