WD19 docking stations - network dropout, USB dropout across multiple models

The couple of PC's I manually manually unticked 'stop devices when my screen is off to help save battery power'. Still disconnect from network when locked.

I have also logged into device manager and where the power management setting is available on USB and Network card, i have unticked 'Allow the computer to turn off this device to save power'. Again the laptop is disconnecting from the network when the screen is locked. This cause their programs to crash.

I've also tried some of the registry changes to show additional sleep timings in power management. Again these haven't helped.

We are using Latitudes 5500 laptops with the Dell WD19 dock. Windows 10 Enterprise 1803. All drivers and BIOS are up to date, including the Realtek  drivers for the dock. The network connection is via ethernet cable.

Are there any other suggestions to try?

Windows 10 solution for network stop working (it worked for me):

Device manager -> Network adapters -> Realtek USB GbE Family Controller -> Properties -> Advanced

Disable 3 items (sorry but I can only write it in portuguese as my windows is in... portuguese eheheh):

1) Ethernet de consumo de energia eficiente

2) Ethernet verde

3) Idle power saving

In case you don't have these options, you must first install latest drivers with WD19 dock connected.

We purchased three 7740's and the WD19 dock station.  The dock is pure garbage.  Blue screens, lock ups, USB ports disconnecting, and the Ethernet port dropping out.  Once we took the dock out of the equation the laptops are solid.

Maybe in another 3 months Dell will figure out what the hell is going on and fix these.  We had similar problems with the 7710's and the dock.  After about 6 months they were solid after many firmware and bios updates.

How Dell lets something like this happen over and over with their new products floors me.  Especially when you pay 7k for a laptop.

works also for me changed "Energy-Efficient Ethernet" to disabled and now the ping to google.com is stable

I found that changing a lot of the "green" energy saving items made it marginally more stable, tried changing the power profile on the PCI Express bus to off, but it still drops occasionally.  Sometimes not at all during a working day, sometimes it goes down so much that windows disables it.

Today, so far, it has dropped just once, and that was about 30 minutes in to the work day.

Presently, at least with the machine I'm using, there is no way to stabilize the ethernet port.

Now that I could read the print from @proempie , let's re-list, now in english, the 3 items people have to disable in order to make network works ok:

1) Energy-Efficient Ethernet

2) Green Ethernet

3) Idle Power Saving

Have a good surfing!!!

Note my network is working without any fail since I configured like this (4 days ago). 

Thank you for posting that solution. But unfortunately it doesn't seem to have worked. I changed the settings yesterday, but the user is still reporting the issue today.

I'll keep looking. there will be a setting somewhere.

We are thinking on buying other dockings. We cannot role out Windows 10 on 2000 laptops.

Network drops on Dell 5400 when connected to the WD19.
This issue does not occur when the cable is directly connected to the docking.

bios verson 1.5.1 (latest)
Laptop Dell 5400
updated all drivers to the newest version
updated all firmware
updated the bios
disabled all powersettings in devicemanagement (allow the computer to turn of this device to save power)
disabled (energy efficient ethernet/green ethernet/disabled idle powersaving)
disabled (stop devices when my screen is off to help save battery)

Hi All,

I have an incident opened with Dell about this issue and their last answer is that the Latitude 5400 is not fully compatible with Win10 Enterprise, only with Professional. I hope this is a bad joke but just to double check, what version of Win10 do you have installed?

I'm having similar issues with network connectivity not working at all or very inconsistent with the WD19DC. Like many others this is happening on multiple 7450 w/ the wd19dc dock. We run Windows Professional so don't let them lead you down that ridiculous path that Enterprise isn't supported.

I'm asking for a refund on the docks that we currently have and testing startech.com docks.

I already told them I'm not buying it but I asked for an official confirmation from the commercial. If, and that's a big if, he says the same, I'm gonna ask for a refund on laptops and docks...

I didn't ready through all the pages on this topic, so if this is a repeat solution, sorry., 

The only luck that I've had with some of the laptops using this dock was turning off both battery and plugged in "Link State Power Management" in the advanced settings in battery options. 

Other than that the dock just  and was pushed to market way to quick probably trying to trying to recover from all the issues of the previous single port docks. Everything after the E port dock has come with problems that haunt IT depts.

I also am having this issue, would love to hear a solution!
