USB-C Dock G5 and HP Probook x360 435 G7

[Argh_sk]

Hi There

We as a company have quiet a few new HP Probook X360 435 G7 paired with the HP  USB-C Dock G5.

All have the same annoying problem:

Once or twice a day the network interface of the USB-C Dock G5 stops working. No eventlog-entry, it just stops sending out or receiving data.

Other parts are working - sound, connected displays, usb (mice, keyboard) all fine.

Workaround is disconnecting the USB-C-Dock from the notebook, then reconnecting it. After that everything works fine - until the network card randomly drops out.

It also helps to pull out the lan-cable ans put it back in - most of the time.

Firmware (yes, also the USB-C-Dock) and drivers are up2date (hp image assistant), Windows 10 is 20h2, patched up2date.

Also reinstalled some systems - just to make sure, that the windows-Installation is not borked somehow.

Also tested the originial realtek driver, since it's a newer release - not much difference here.

Network switch(layer2) shows no errors for those users (CRC count) - the link is active, just no data - just to make sure, I replaced some patch-cables anyway.

 ATM I'm out of ideas on how to continue here- looking forward for any help

Hey! 

I've struggled with this issue on about 15 of these Probook x360 435 G7 with a USB-C G5 Dock as well. 

Quick workaround is to use a USB Ethernet adapter. I've seen that patch the issue with varying results. 

I got two of these laptops in stock recently, and did not reinstall windows on them. The stock HP image does not seem to have the issue from several days of testing. To test the issue I basically plug the computer into the dock, and start a teams meeting. So far I've had the meetings time out at the 24 hour mark twice. My base Windows 10 image actually will drop connection with the same test in about 4-5 hours. I'm unsure what is causing this issue at this point.

I have had this issue with numerous ProBook 650 G8’s using the G5 dock.  After installing any and every update and Firmware I could find, I think I have finally found a temporary solution.  Today we rolled back the Realtek USB GbE Family Controller driver from version 10.38.117.2020 to 10.5.920.2015 and it seems to finally work.  

I sent a long email to MyHPSupport with this information and hope they do something about it.  I was about to switch to Dell.

A short update:

Disabled the USB adaptive powersaving in Windows 10 via powershell script.

Situation is much better now.
