    I just got AT&T Fiber internet and my connection on the 2011 MBP via ethernet is about a 980mbps. Using the Belkin USB-C Gigabit ethernet adapter from the Apple Store, I am doing well to get 500 mbps on the download, on my new late 2016 tbMBP. Is anyone else having trouble seeing good speeds with an ethernet adapter? Are there any other adapters where I would do better?

    I think your only other option is from StarTech.

    it's also possible your router can't handle that kind of speed.

    Not familiar with them. Are you talking about an adapter or a powered dock?

    The router can handle the speed. Other windows users in the house are also getting 980 on the download.

    What is weird, is my upload speed is excellent at 920 (average). The download speed is about half what it should be every test.

    Maybe try Apple's TB3 to TB2 adapter connected to their TB2 Ethernet dongle?

    Strange, I've tested mine using iperf to a local server on our gigabit office network and I'm getting ~920. You don't have it plugged into the back of the LG 5k screen by any chance?

    No external monitor.

    It is strange indeed. I have been seeing 475 - 675 on the usual speed sites. The ATT speed site is the only one that shows me about 835 - 850 on the up / down.

    I have also the Safari shows lower numbers than Chrome.

    I wonder if the Belkin USB-C to Ethernet adapter is the culprit.

    Well it doesn't sound too far fetched that Belkin may have gone a bit cheap thinking they're going to be able to get away with it as most users don't even get close to those kinds of speeds.

    What about copying files over LAN? I do not have the Belkin adapter but one from Aukey I think. Nevertheless both adapter have the same Realtek chip in it and my Aukey adapter gives me nearly 1 GBit/s over LAN.

    I have copied over LAN, but didn't think to check the speed. Thanks for asking. I will check it when I get home.

    I have the "Plugable" brand coming from Amazon today. Will be interesting to see if speeds are any better.

    Forgot to mention earlier, I plugged my new Mac directly into the UVerse gateway yesterday, and speeds showed about the same. That is what made me start thinking it could be the adapter.

    Try using iperf to check between your notebook and another machine on the network (it is a well known and very good tool for network performance testing). Don't rely on speedtests on the internet because you add more parameters (iow you make it more difficult because there are more things at play). It isn't uncommon that speedtests on the internet can't reach 1Gbit/s.

    As for my own Belkin USB-C ethernet adapter...I did a quick test with iperf to check and it reaches 1Gbit/s without problems.

    It is strange, I am using belkin and transfers from/to my NAS are about 100-120MB/s which is almost 1gbit...
