Thank you, Alex!

 

Just a question, please bear with me: if I install this driver, won' my PC try to automatically look for a newer one? I apologise if this is a stupid question, I' not really sure how Windows Updates/Lenovo Vantage really work!

 

Hi Clawdia,

 

as mentioned one post above "If implementing this work-around, disable automatic driver update in Windows Update settings."

So disable automatic driver update like it is described here: 
How to disable automatic driver updates on Windows 10 | Windows Central

 

 

My apologies Alex, all clear now. Many thanks!

This will be an odd question given the forum. Is this happening with other non-Lenovo products? Surely this Realtek chipset / driver is used by other OEM? When you search  for this you only come back to this thread or other forums with people mentioning Lenovo. Is this an implementation issue with Lenovo and Realtek?

No, it isn't.

Re:rtump64x64.sys bluescreen on X1 Yoga Gen 4 attached to ThinkPad Thunderbolt 3 Dock - Type 40AC

Thanks for those extra links. I've been reading up on that Spiceworks forum link. For many there it seems like the latest drivers from Lenovo solved the problem (drivers issued from around Jan 21, 2021) - and some of those even had the same Dock my company uses, the "ThinkPad USB-C Dock Gen 2 (Type 40AS)".

 

Are others still struggling with this issue? Right now we have the workaround of just moving the net cable from the Gen 2 Dock directly to the T15 laptop. I'm worried about trying to install the latest drivers and having the problem escalate into the BSOD errors some have reported.

 

I tried opening a support ticket with Lenovo on this issue. Even though I can't reproduce it, I was hoping for some feedback that Lenovo was working on this issue or had resolved it. I heard back nothing and when I later searched for my ticket on their website I found that the tech had just closed the issue as "resolved" as soon as they had hung up the phone with me. Very poor service. Why am I not seeing more of a Lenovo tech presence on this forum?

Many on the Spiceworks thread were experiencing the original Realtek Ethernet driver issue of dropped / disconnected Zoom / Teams calls. The newer driver seems to have fixed that for some. For others who weren't for the most part having issues previously this newer driver (10.43 / 10.44) has introduced a new problem of bluescreens from the driver. That newer issue has yet to be resolved. There was a test 10.45 driver which didn't seem to make things better. We are still waiting on fix from Lenovo / Realtek. It is unclear if the issue is affecting other docks / USB dongles from makers like Dell / HP in the same way as the Lenovo. If not it may be something specific to the hardware implementation by Lenovo?

I have a HP Elitebook 855 with an usb-c dock G5. I have the issue of losing the network connection during a Teams call.

 

The laptop itself has no ethernet port, so that is not a workaround for me.

 

Using wifi is a workaround for me. And for the time being I am using a usb-ethernet adaptor with an asix-chipset. Works fine.

 

Still no solution....

I have a Lenovo Yoga 920, connected to a Lenovo Thunderbolt Dock and have this exact same issue in 2021. Totally sick of it, the BSOD is actually affecting my work and business because I have been shut out of  important meetings in the middle of a video call/presentation.

 

This is shockingly poor customer support. $1800 laptop, $225 dock, and this is what we get? 

 

What information can I provide to effectively troubleshoot? Just stumbled upon this forum/thread after a google search of the same issue as it happened again today. 

 

I even went as far as reloading Windows on my machine because it had gotten so bad, was happening multiple times a day. 

 

I will never ever buy a Lenovo product again, and I run a business, will go for a total ban on Lenovo.

I agree with your frustration. However I will say there are workarounds posted earlier in this thread of mostly installing an older driver that will get you back working. Oh and I have spent way more than $2000 on this equipment, like 10x this year alone.

Thanks Brian!

 

I just found the post where I can go back to 10.33 version of drivers and stop the automatic driver updates, would that help with the BSOD?

 

Sorry, I just found the thread and was starting from the last page and reading backwards. I saw the link for download on Page 10, going to try that now. 

 

And correction, my dock is Thinkpad Thunderbolt USB C dock, provides a single connection to the laptop for power and display and ethernet.

Should I go to 10.33 or is 10.38 okay to avoid BSOD? I found 10.38 on my machine and can revert to it.
