Windows 10: Ethernet Adapter Not recognizing connection

Brand new computer, has a Killer E2500 Gigabit Ethernet Controller.


My computer will never recognize that I have plugged in ethernet unless I restart the computer with Ethernet plugged in.


Running on the latest driver.


Any help would be appreciated,


Thanks.

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

 

Ethernet Adapter Won't Recognize Ethernet Cable

We have a Dell all in one touch screen computer and we want to connect our modem to it. However I noticed that the connection icon on the right bottom hand side doesn't indicate that there is a wired connection.

So I went to the network adapters page and it says "network cable unplugged" even though the ethernet cable is in there. I thought the ethernet cable might be the problem even though it was working fine for the other computer. So we switched it out and the
computer still won't recognize that an ethernet cord has been plugged in.

Then I used my mobile hotspot to install the latest driver for the ethernet port and it installed. The driver date went from 4/2/2015 to 5/2/2015. I restarted the computer and tried both ethernet cords again and same result. So then to be sure it was the
computer I put the ethernet linking the modem to my laptop and my laptop recognized the wired connection.

So it's not the cords or the modem, it's the computer. But I can't figure out how to fix it and I find it hard to believe that this is a hardware problem given that this computer is fairly new.

The OS is Windows 10 and the Ethernet Adapter says Realtek PCIe GBE Family Controller.





If our computer can't recognize ethernet cords we can't use our modem...

 

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?
