I have 2017 15 inch Macbook Pro with 512gb of SSD Storage, 16 gb RAM, and the 4GB Radeon Pro 560.
I bought a USB C hub that had an ethernet port and I decided to plug an ethernet cable into it. I noticed that it was only showing as 10/100 instead of 10/100/1000. Additionally, I looked into my Macbook Pro hardware specs and it also showed or displayed as the same.

I also did a speed test and it was only giving me around 90 instead of the 100+ I usually receive even on Wi-Fi.

I was wondering if this was normal.

Yeah, I disconnected it from the ethernet switch (which is a gigabit ethernet switch) into the router, and still got USB 10/100 on the hardware specs and same internet speeds. I believe that the 2017 macbook pros should all have USB 10/100/1000 (gigabit) enabled, not dependent on the ethernet.

I did do a fresh reinstall of MacOs in order to remove parallels about a week ago, since I didn't need it for my com sci classes anymore. Windows 10 was taking up a good chunk of space.

I bought the Macbook Pro recently, about 3 months ago and have AppleCare & AppleCare +. I could probably take it into the apple store if all else fails.
 
Are you sure that the USB-hub supports 10/100/1000? The USB-hub defines the speed, not the MBP.
 
The USB-C hub (HooToo USB C hub) does indeed support gigabit ethernet.
I'm just finding it a bit odd that my system specs is displaying 10/100 instead of 10/100/1000.

If it’s displaying 10/100, then that’s because that’s all the device is offering to the computer.

The Ethernet Router, Switch, Hub, etc. determine the speed your computer can communicate at on the network.

Doesn’t matter how fast the network port is on your computer. The device you plug your computer into will determine the speed. It will not show Gigabit if the device isn’t offering a Gigabit connection to your computer.

From what I’m reading, it appears that your HooToo is creating a USB 3.0 Bus. Ethernet over USB is never a strong performer.

USB 1, 2, and 3 are shared bandwidth with a theoretical maximum that is rarely ever achieved.

I would suspect that you either have a driver issue, or a bandwidth issues if the HooToo is not providing a Gigabit connection.

However... let’s assume for a moment that the HooToo is providing a Gigabit connection.

You are still connecting an Ethernet cable between the HooToo and another Device (Router, switch, Hub, Modem, etc).

If that device isn’t offering Gigabit connections on the LAN ports, then your HooToo is going to step down to 10/100.

And even if that device is Gigabit... if it’s plugged into anything else that isn’t Gigabit, then it will step down to 10/100 as well.

Essentially, you need to research and test everything that’s in your network. The weakest link determines the maximum speed of everything.

And... never assume that any Gigabit device offers Gigabit on every port. Usually they don’t.

Mac or PC... you can’t get Gigabit on the computer if your Ethernet is not supplying Gigabit through the entire connection.

Everything that is in the line between your Internet provider and your computer will determine your maximum speed.

If you have 2 inch pipes throughout your house capable of delivering 7 gallons per minute to every faucet, you expect 7 gallons per minute flow. But suppose one of the lines close to the water pump is the size of a straw... it’s going to slow the water supply to every faucet to a dribble. Doesn’t matter that the faucet and the rest of the pipes are rated for 7 gallons per minute.

Do you have correct type of ethernet cable? If it's not at least "fully connected" cat5e then it doesn't support 10/100/1000.
