Windows 11 & issues with network connection on a dock

BIOS from Laptop. For latitude 3520 we tried 1.21.0 and windows 11 22h2 without having any Network issues for now 6hours. 

I have see the issue on all the latest BIOSs. This includes our 5420s with 1.21.0 and 1.22.0 that was just released two days ago. It only happens every few days for us so it is hard to say that it is stable after only 6 hours. 

We have narrowed the issue down to any Windows 11 22h2 computers connected to the Docks or monitors using a Realtek USB GBE Ethernet Controller Driver. For that reason I don't suspect a computer's BIOS firmware would be the ultimate fix. Dell did just release a new Realtek USB GBE Ethernet Controller Driver today. 1153.9.x. I am trying that on one test computer and leaving the second test computer alone. Like I mentioned the issue doesn't happen every day so It might be a few days before we know if it has helped.

Monitors with Ethernet:

They are listed differently on Dells support but I suspect they are the same driver.

I just tried the updated drivers/BIOS...minutes later, I've got the world symbol again.

After update, tried various versions of enabling/disabling, the Wake on Magic Packet, Energy-Efficient Ethernet, Green Ethernet in the Realtek USB GbE Family Controller, none of it worked. If I messed with a setting, I'd get my ethernet signal back for a few minutes, then back to the World Symbol and network trouble again. I just unplugged the Ethernet cord again, back to WiFi.

Work/Enterprise network. Though, when I work from home (I have a dock set up there as well) I still get the same problems if I try to use an ethernet connection. My only resolution so far has been to leave the ethernet connection unplugged on the dock and just stick with WiFi.

I'd hold off using Windows 11 in an enterprise situation until they resolve the problem. Or buy something that isn't a Dell.

Thanks for the tip about plugging the ethernet cord in directly...like you said, it works, but isn't optimal. Haven't seen a fix from Dell for this yet.

Here's an other variant of the problem:

- Dell Latitude 5430 (BIOS 1.7.0)

- Dell Docking Solution WD19S (latest driver for Realtek GBE Family Adapter according to "Command Update")

- Windows 11 22H2 wit all the latest updates

Symptom: LAN cable attached to notebook directly works seamlessly. LAN cable attached to docking solution does not work at all. Electric connectivity seems to be OK by looking at the blinking LEDs but Windows says that there is no cable attached.

Tried various solutions to no avail ... if we want to have a cable connection we need to attach the cable to the notebook directly. That is really annoying since docking solutions are meant to reduce (un)plugging of cables.

Thank you in advance for addressing this quickly

Hi,

I too face the same issue. I have Dell 5520 with Windows 11with a Dell docking station WD15. Even when network cable is connected the network gets disconnected quiet often. If I wait for a couple of minutes, network connects back on its own. Do anybody has any solution for this?

Dear Community,

in addition to my post from yesterday I would like to add that the Windows Update feature just installed a driver version 11.53.xxx for the "Realtek USB GbE Family Controller".

You assume right that the result was a complete loss of network connectivity with the following (odd) symptoms:

- Network symbol in system tray shows a valid, wired LAN connection

- "ipconfig /all" vía command line shows a valid IP configuration

- "route PRINT" via command line shows a valid route to the internet

- "ping 8.8.8.8" or any other hostname via command line results in "no route to host"

So if you experience this kind of behavior suddenly go to "device manager" and revert the installed driver to the previous version as shown in the following screenshot:

THX for your attention

Have you found a solution for this?  I am having the same issue. 

Outside of plugging the ethernet cord directly into the laptop instead of the docking station, no.

Have you seen any improvement after applying the new driver dell published? Either .9 for the dock or .6 for the monitor w Ethernet. I think we are getting better results, its definitely less offten.

I have the impression that this problem particularly affects the Dell latitude 5520.
Indeed we have several customers with WD19 and Windows 11 stations, and they almost all have the problem.
But this only affects those with 5520s.
The latest version of the driver seems to have reduced the frequency of disconnections but this does not solve the problem anyway.
It's quite annoying and the only workaround is to connect the network cable directly to the computer or go exclusively to wifi.
Do you have any further information on this
