Windows 10: Where is my ethernet adapter

I am now connected to the Internet through a Wi-Fi adapter. I used to be connected through a wired ethernet connection. When I go to Device Manager, I see under Network Adapters, Realtek PCIe GbE Family Controller with a little yellow triangle. When I click on Properties, I read "Windows cannot initialize the device driver for this hardware code 37." How do I recover the Ethernet adapter and where is it? I am totally confused as to why my computer uses Wi-Fi instead of the original wired ethernet.

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

 

My ethernet adapter is named "Ethernet 2" and there's already a device named "Ethernet"?

Hi Bhargav,

Thanks for your suggestion. I ran your file as an administrator and the only "net" device listed was a Hyper-V networking adapter that appears to not be currently connected. I've already been able to confirm that the Hyper-V adapter does not have the name
of "Ethernet".

Any other ideas?

 

GRAH! Ethernet adapter NOT working!

thanks for the replies guys.

i tried most of whats been suggested already. restarted router, installed the latest drivers from nvidia for the nforce chipset + ethernet, and the adapter isn't disabled (its getting a wacked out ip address compared to the rest of the systems on the network, and occasionally, i can ping.)
