    Constant disconnects very frustrating

    • Written by Brian Z from SAN FRANCISCO

    Bought the highest end MacBook Pro on the market at the time and from day one, this adapter has had a major engineering flaw, at least with my MacBook Pro Mid 2015 15inch. Any slightest movement or jiggle of the adapter base at the socket of the Mac, even the movement from pressing palms to the keyboard is enough to cause an internet disconnect. I can replicate it 100% of the time, and my testing has insured it's not the ethernet cable going into he adapter. I can literally watch my connection disconnect and reconnect in the Network Preferences as I touch the plug. I know it's not a defect with my specific adapter either, but rather a design flaw (the plug on the adapter is simply too loose for the female port on the MacBook Pro). I have swapped my specific adapter with other people's identical ones and also have the same effect of connection loss with any movement. I have been an Apple fanboy since my Mac Plus and this has been my first disappointment. Really wish they would have just left an ethernet port on the machine.

    Another observation - this might go under reported due to wireless Wi/Fi, as it will eventually just switch over from the dead ethernet to Wi/Fi and many people might not even notice it disconnected at all, unless they're on an application that required a constant connection. For example, if they were just web browsing, it might not be noticed.

    I had bought this ethernet thunderbolt connector at apple online store due to lack of USB port for MACbook Pro on 2 January 2019. I got it on 10 January 2019. Today, 16 January 2019, it was spoiled. No respond when I use it to connect to internet. What a disappointed overpriced product?
    I'm really mad about this.

    So far so good

    • Written by Lester B from Longboat Key

    Just purchased MacBook Air & needed ethernet adapter so i can connect to Comcast without using wifi connection. So far works great with very high speed. Not sure about the negative product rating. A puzzle to me. I give it a 5 star rating *****.

    Flimsy thunderbolt plug, stopped working after few months

    • Written by Maciej R from London

    It usually works fine until you move your device. Often disconnects if you touch it and falls off if you move your device.

    The issue with pretty much all thunderbolt 1 and 2 apple connectors that I used including display cables.

    I think it is greatly overpriced considering this problem.

    On top of that it stopped working after few months.

    Save yourself a hustle and get a cheap USB3 to Ethernet adaptor from ebay (around £6).

    Doesnt fit Thunderbolt 3

    • Written by Goetz K from Woodside

    I bought this to do port trunking on my 2017 iMac - so I as a user thought Thunderbold fits - but unfortunately APPLE DOESNT TELL ITS ONLY THUNDERBOLD 2 - and my iMac has Thunderbolt 3

    Great little adapter for a decent price

    • Written by Connor M from Gladstone

    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.

    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!!!!

    Best MacBookAir (2011) to Ethernet Connection Option

    • Written by Terry M from Floral Park

    Recently found by accident. Big speed improvement over USB to ethernet, plus gaining back the USB port is huge.

    Did notice that the Thunderbolt connectors can become disconnected, but when the etheret speed drops, its the obvious fix - so not a big deal for me.

    Using the Thunderbolt 2 port for an external hard drive is probably the best use of this port, but unfortunately I guess it doesn't make sense for drive makers at less than a $400 price point.

    Works well for me on High Sierra, no issues

    • Written by Andrew H from Moraga

    I was skeptical about buying this at first due to the review but it has performed without issue for many months now.

    Great buy.

    • Written by Deborah M from Arlington

    same as others have reported, it gets unreliable and then stops working altogether. I can't think of any reason a part like this should "wear out"

    I'm not on my third example of this device: the first one lasted just over two years; the second only four months. In both cases, the symptoms were a complete device failure, coupled with it actually getting too hot to touch. When it works, fine, but not reliable. And that's before we get into the idiocy of Apple removing ethernet from their computers.

    Works Great

    • Written by John C from Golden

    I've had one of these and used it for years without any issues. Can easily saturate the gigabit connection at around 980 Mbps up/down.

    Poor performance

    • Written by Bijay S from Kolkata

    I bought MBP along with Thunderbolt to Gigabit Ethernet Adapter. For some reason, either with the adapter or the port or both, the internet connection keeps dropping. When the connection is dropped, i attach the ethernet cable to Del laptop, it works just fine. So the problem appears to be with the adapter/port. The adapter also get very warm, which is normal as told by Apple staff. Net conclusion: very frustrating to lose internet in the middle of work.

    Room for Improvement

    • Written by Clancy C

    The dongle actually works okay in a physical sense and isn't annoying or anything but I use it every single day for work in a secure environment which requires ethernet connectivity. If I lost my network access while I'm working it limits my productivity and this happens at least half a dozen times a day whenever anyone knocks the ethernet cable or adapter. I just wish it worked as well as an ethernet cable, there is truly no substitute for time tested solutions.

    Waste of money

    • Written by Caroline G from Deptford

    I had to go buy this after an apple employee told me nothing but the thunderbolt would work as an ethernet adapter on the mac. Under system report, the thunderbolt shows up as connected but under network it won't work. I spent over an hour on the phone with tech support trying to trouble shoot just to have her say 'I don't know what else you want me to do' and hangup. Wasted my money because this doesn't work and I still dont have internet access.

    Ease of Use & Reliable Virtual NIC Teaming

    • Written by Anthony C from Singapore

    I have one of this 'Thunderbolt to Gigabit Ethernet' adapter for the last 1+ to 2 years. It has served me well and works seamlessly through the update of macOS from Mountain Lion (I think) to Sierra to now High Sierra on an iMac. I vividly remembered there was one or two minor bugs back with Sierra Public Betas but it was sorted out at official release.

    The 'Thunderbolt to Gigabit Ethernet' adapter is easy to install (just plug in and it works) and even easy to configure virtual NIC teaming to allow redundancy in connectivity. Fail-over works seamlessly too and maintain connectivity to the network when the iMac onboard NIC's connectivity is down (e.g. primary network switch's firmware update and reboot).

    I am not able to recall what is the typical throughput of this 'Thunderbolt to Gigabit Ethernet' adapter. I vividly recall it is not the most fantastic throughput but given it is afterall an external adapter, some overhead loss is expectable. No compatibility issues experienced which may indicate the chipset used in this adapter is fairly compatible with that used in the network switches I have (Ubiquiti Edge Switches).

    I've had my adapter for about two years with limited use. It sporadically drops my internet connection, which is not great while taking online exams or gaming. I'm not satisfied with the longevity of this product.
