Question Network disconnects when using ethernet - usb type c adapter

[puma2133]

I'm using a base model macbook pro 2017 without touch bar. Currently running mac os sierra 10.12.6 (16G1314). Recently i bought a USB Type C - ethernet & 3x USB adapter: https://www.onlinekabelshop.nl/usb-c-naar-3x-usb2-0-hub-ethernet-lan-adapter-0-15-meter. When i plug in the adapter my network stays connected for 30-40 seconds then disconnects and automatically connects again as in the .gif included. It's truly a nightmare for someone working constantly with internet.

I tried using a brand new cable for ethernet but it didn't solve it. Also i tried using other ports from the router but no success either. I thought that maybe the problem is in the adapter itself but i also use two of its usb ports and those devices never get disconnected.

Note that before i had it working i had to install the latest Realtek driver for the adapter. I appreciate every advice on solving this problem ! Thanks !

I encounter a similar issue with a cheap USB hub/Ethernet adapter.
I used two other Ethernet adapters and the issue is no longer present.
I tried the Belkin USB-C to Gigabit Ethernet Adapter without issues.
I purchased the Anker USB 3.0 Portable Gigabit Ethernet Adapter (I use a USB 3 to type C adapter) and it works fine and no more disconnects.

So I assumed the USB hub/Ethernet adapter wasn't working properly.

I've bought 6 quite expensive adapters and none of them work. I installed windows 10 through bootcamp to test the internet and it worked flawless. I have no idea why it's not working on Mac. I've tried updating to the latest version of macos and it's still not working

Since you got expensive ones, did you try the one from Apple store?
