We are facing issues with WD19s losing Ethernet connections pretty consistently and also USB dropping out randomly throughout the day.
This happens with our latitude 5400 laptops.
The issue persists after we had the motherboard and other parts replaced, 3 new WD19's, and fresh installs of OEM image and latest BIOS and drivers on laptop and dock.
The issue does NOT occur with the WD15 dock and 5400 latitude.
Dell indicated moths ago there would be an August update of the docks firmware. This has not been released.
Has Dell acknowledged this as a known issue ?- there seems to be multiple posts with this same issue with other laptop models.
We were planning on purchasing this model for our fleet...
Dell, any comment?
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.
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.
For the last several days, my WD19TB would drop ethernet just once in the morning, and then it would stay stable for the remainder of the workday.
Yesterday, I went to the office where I have a WD15 dock. I stayed on that for 9 hours without any sort of issue. No drops of any kind, etc. No other drivers to install, no other changes needed to be made.
Today, back on my WD19TB, the thing disconnected multiple times an hour. After dealing with it and then getting frustrated after being disconnected 5 times, I plugged my ethernet back in to my laptop port, and continued to watch the dock ethernet drop out repeatedly for the entire day, multiple times an hour, with no network connected to it. I had my sound on so I could hear it every time it dropped (plays a USB disconnect sound), and I had my network settings open so I could watch it disappear and reappear.
The Dell rep who has responded on this thread has indicated that the Dell engineers HAVE replicated this issue in their lab and are working on isolating the problem. It's either going to be driver or firmware, but should be fixable with some sort of software update.
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.
