Hello ,

Good to see you in Microsoft Community.

Firstly, could you let me know the specific system version (OS Build)? You can check it by pressing Win + X > System > Windows specifications, click “Copy” and paste it in your next reply.

You can follow the steps below:

1. I suggest that you check if the Ethernet adapter is enabled in the Device Manager. To do this, follow these steps:
   
   1. Press the Windows key + X and select Device Manager from the list.
      
   2. Expand the Network adapters section.
      
   3. Look for the Ethernet adapter and check if it is enabled. If it is disabled, right-click on it and select Enable device.
      
2. If the Ethernet adapter is already enabled, try updating the driver for the Ethernet adapter. To do this, follow these steps:
   
   1. Press the Windows key + X and select Device Manager from the list.
      
   2. Expand the Network adapters section.
      
   3. Right-click on the Ethernet adapter and select Update driver.
      
   4. Select Search automatically for updated driver software and follow the on-screen instructions.
      
3. If updating the driver does not resolve the issue, try uninstalling and reinstalling the Ethernet adapter driver. To do this, follow these steps:
   
   1. Press the Windows key + X and select Device Manager from the list.
      
   2. Expand the Network adapters section.
      
   3. Right-click on the Ethernet adapter and select Uninstall device.
      
   4. Restart your computer.
      
   5. Windows will automatically reinstall the driver for the Ethernet adapter.
      
4. If none of the above steps work, you can try resetting the network settings on your Windows 11 computer. To do this, follow these steps:
   
   1. Press the Windows key + I to open Settings.
      
   2. Click on Network & internet.
      
   3. Scroll down and click on Network reset.
      
   4. Click on Reset now and follow the on-screen instructions.
      

If anything is unclear, please do not hesitate to let me know.

Best Regards,

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.

 

IP configuration not valid - interference from ethernet adapter?

Solution 1: No Internet Access In Windows 8.1or Windows 10

Step 1:

Go to Device Manager → Network adapters.
Step 2:

Expand it (Network adapters).


Step 3:

Select your network adapter


Step 4:

Right click on your wireless network adapter or Ethernet adapter and then tap “Update Driver Software”.
(in this case your network adopter is Ethernet adopter so tap your Ethernet adapter)
Step 5:

Now on a new window you will need to click on “Browse my computer for driver software”.




Step 6:

Then select “Let me pick from a list of device drivers on my computer”.



Step 7:

Now choose the “Manufacturer’s drivers” from the list of two and then click next.



Step 8:

After the completion of the process just restart your PC and check if the problem is solved or not. If not, goto solution 2.



Solution 2: No Internet Access In Windows 8.1,windows10

Step 1:

Open command prompt.
Step 2:

Just go on hitting the enter after typing the each command.
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disable
netsh int tcp set global rss=enabled
Step 3:

Now to check if the settings are disabled type:
netsh int tcp show global
then hit enter.
Step 4:

Now the thing left is just rebooting your system and just check if the problem is solved or not and just give feedback.*chuckle*Thumbs
