      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.

      Constant disconnects very frustrating

      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 2 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.

      STOP WORKING IN A WEEK OF USING IT

      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. 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.

    • Can I use this cable to hook up a Time Capsule to my iMac?

      Best Answer:

      This adapter is not necessary to connect your iMac to your Time Capsule for internet access and for This adapter is not necessary to connect your iMac to your Time Capsule for internet access and for your Time Machine backups. Time Capsule and iMac can be connected via Wifi. In almost all cases, though, using this adapter with a decent ethernet cable (I recommend at least a Cat 5e ethernet cable) connected hard-wired to your Time Capsule will not only improve your internet speed on your iMac, but also your Time Machine backup speed. The actual improvement in speed of these things will depend on your current internet speed and distance between the iMac and Time Capsule along with other possible interferences. In most cases, though, I would say the average user would notice a slight increase in performance, and the power user to notice a significant performance increase. If you deal with backup up many large files and are a heavy-bandwidth user, I woul definitely recommend using this adapter with either a Cat 5e or Cat 6 cable.

    • 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"
