Windows 10: New Ethernet Adapter not connecting

The new Ethernet Adapter --Greatangle Multiple USB-C USB 3.1 Type C to USB RJ45 Ethernet Lan Adapter -- which arrived yesterday via EBAY after many weeks, is not working. Before I enter into the return / replace / refund procedures I would like to have confirmation (or otherwise) that I have checked everything possible. I now have two adapters, the old USB 2 (Ethernet 7) and the new USB C / 3 (Ethernet 2, in the clip above). I can have them both plugged in at the same time so when I switch the old one off my service switches instantly to WiFi indicating 2 is not working for Ethernet (it also has USB sockets which do work OK). I have changed around and checked all manner of things, including the cables, the Hub sockets, the PC sockets. I have also checked W 10 OS, such as Device Manager, and Settings. No errors / failures / absences are shown. The new Adapter is reported to be "working well" (though I don't trust that to mean anything, from past experience). In Settings Ethernet 2 is shown as not connected whereas 7 is shown as connected, and the result is the same with 2 if I switch cables / cable adapters, PC and Hub sockets. I have used the Troubleshooter which reports an error, ie. a device is not connected.

So I think I have done a thorough inspection. Is there any other possible cause of the problem I have not checked?

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?

 

IP configuration not valid - interference from ethernet adapter?

I tried both of these solutions (have same problem, but to expand, my wireless doesn't connect to the internet either), and neither worked. Have intel AC 7260 wireless, and Atheros AR81g1 Ethernet (NDIS 6.30). Hope someone comes up with a solution soon. Windows 10 has been working....well, OK, for about a year on my personal laptop. My system bricked when I installed the Windows 10 Anniversary edition. Had backup on 2TB external drive. I installed clean windows 10, and all worked fine, including internet access on both wireless and ethernet, but needed to reinstall from my backup because of a lot of programs, and data there. Backup was about a month old (yeah, I know, backup more frequently). After a successful backup, I again attempted to install anniversary update. This time it installed successfully, and all appeared good until I tried to access the internet. Now my case is per above. Can't access from either Ethernet or wireless. It connects fine to my router (which I'm connected to on my company laptop right now), but it will NOT connect to the internet. HELP!!
