Hi,

yes I had the same problem on both my XPS laptops. I solved it by going to Device Manager/Network Adaptors and altering the Advanced Properties. In my case the network adaptor is a Realtek USB FE Family Controller. Scroll down the advanced properties list and disable Energy-Efficient Ethernet. Scroll down further to speed & Duplex and set it manually to 100 Mbps Full Duplex so that Auto Negotiation is switched off. Since doing this I have had no further problems even when using a non Dell Ethernet to C-Port adaptor from China.

Good luck

Sadly, Zoom worked for 10mins then same issue came back.

-Energy Efficient Ethernet set to "Disable"

-Speed & Duplex set to "100 Mbps Full Duplex" 

Thank you, will give that a try and report back soon

Did you ever find a solution? I had the same problem and have just been using Wifi instead

I also have this issue using a usb c adaptor - VAVA adaptor RJ45, keeps losing internet connectivity very frustrating, will try the suggested solution and report back...   tx Paul

I have same issue on my new Dell docking station Dell WD19-130w / WD19TB and VAVA USB-C hub.

some news/solutions on that topic??

We have the same issue on 4 new Dell XPS 13 laptops (BNX93005)!

We have Philips 34" widescreens with wired ethernet, connected to the USB-C port on the laptops. The ethernet connection drops a couple of times a day, usually during TCs.

Unplugging, connecting to wifi and then reconnecting to USB-C usually works, but sometimes we need to restart.

Seems to be a common issue and Dell needs to provide a solution urgently.

Similar problem reported at https://www.dell.com/community/XPS/XPS-13-9310-2020-drops-ethernet/m-p/7756073. (That is more relevant to my situation because I have a 9310.)

Right when the network cuts out, I hear the tones that indicate a device was disconnected. Then a few seconds later, I hear the corresponding tone for a device being connected, then shortly after that, I regain an Ethernet connection.

Responding to above messages, disabling the Energy-Efficient Ethernet setting makes a little sense as it could affect power state. However, changing the Speed & Duplex setting doesn't make sense: how does negotiating an Ethernet connection have much to do with whether the computer thinks the device is present?

A common thread in all these complaints seems to be a USB-connected Realtek Ethernet device.

Scratch that. Still getting device drops. Even happens when no Ethernet cable is connected.

When the "you've removed a device" sound is heard, the Realtek USB GbE Family Controller device disappears from Device Manager. It then re-appears after the "you've plugged in a device" sound is heard.

I'm at a loss to explain why any device setting would cause it to disconnect and reconnect. I want to say this is related somehow to Dell software shutting down or restarting the Realtek device. I lean against it being related to Dell hardware as I don't see why the hardware itself would be targeting just one device for disconnects and reconnects.
