XPS 13 9300 (2020) drops ethernet
Have tried two different USB-C hubs (Belkin and HooToo, links below) but ethernet (and internet) keeps dropping every half-hour to an hour. The network/internet icon on task bar would show "Not Connected" all of a sudden, even though the ethernet RJ45 jack LED light on the USB-C hub still flashes green (normal and connected). It's very troublesome especially during Zoom meetings!
Unplugging the USB-C hub and re-plugging it in would bring the ethernet back but the frequent needs to re-connect is unbearable.
Unfortunately this is the part of the home office without WiFi signal so need to use physical cable.
Does anyone have same experience / have solution?
I actually have two XPS 13 (2020) at home and connection is stable for the other one (using Belkin USB-C hub)
Appreciate your help on this.

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
Ian

Sadly, Zoom worked for 10mins then same issue came back.
-Energy Efficient Ethernet set to "Disable"
-Speed & Duplex set to "100 Mbps Full Duplex"

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.
