Windows 10: Windows 11 Pro disconnects Ethernet connection using a dock, if the source in Monitor is...

Have a Dell Alienware Monitor that takes three inputs from laptops. I use it for work, and do not do gamingThe issue is only with Microsoft Surface Laptop 5 Win 11 Pro and Dell Thunderbolt Dock – WD22TB4, when it disconnects Ethernet connection while I am using a dock, if the source in Monitor is switched.I suspected it was power management settings, but could not rectify the issue.BTW, works perfectly fine as long as I am using the laptop and it is the active input source for the monitor. Other two laptops have no issues- even when they are not the active input sources, but I am using a H

surface dock ethernet disconnects intermittently

Hi This is my second Surface Dock (connected to Surface Book) The first one intermittently lost connection to my monitor. After many attempts to remedy I ended up solving the problem by replacing it.

The replacement is working ok with my monitor but now the Ethernet disconnects intermittently. Hopefully I don't have another faulty dock. Any suggestions?

The ethernet connection on my docking station drops out(disconnects) when the external monitor is turned off (also on the docking station HDMI connection).

this is very frustrating as it drops out my VPN for work every time it does...

it is USB 3.0 docking station 4K. (QGeeM)

Windows 11 ethernet keeps disconnecting.

My ethernet keeps disconnecting randomly, especially after heavy usage on Windows 11 Pro. It usually stays disconnected until restart.

My components:

• MSI B550 Tomahawk
  
• Ryzen 7 3700x
  
• GTX 1080 TI
  
• DA850 Gold Silverstone – power supply
  
• Patriot Viper 4 Series DDR4 32GB (2x 16GB) 3200MT (PV432G320C6K)
  
• P5 M.2 SSD
  

What have I tried:

• Changed ethernet cable to new one. – I have tried both ethernet ports on MOBO
  
• Reset modem settings and restart modem.
  
• Almost all software tweaks that I have found online – multiple settings (reset network….etc.).
  
• Upgrade network drivers
  
• Completely fresh reinstall Windows 11
  
• Change power supply and SSD drive.
  
• Update BIOS to the latest version.
  

I'm currently considering that the problem might be related to Windows 11 itself, given that my other computer that runs on Windows 10 doesn't encounter the same issues. It could also be an issue with the modem itself or a possible hardware malfunction. Interestingly, when I utilize an external WiFi dongle, the WiFi connection seems to work flawlessly. I'm open to suggestions for potential solutions or fixes.
