Windows 10: Multiple instances of ethernet adapter created / DNS client using >50%

The system

OS: Windows 10 version 1909
PC: HP Envy Laptop
CPU: Intel Core i7 5500U @ 2.40GHz
RAM: 16.0GB Dual-Channel DDR3 @ 798MHz
GPU: 2047MB NVIDIA GeForce 940M (HP)
Running the paid versions of Avast and Malwarebytes. Both up-to-date.

The problems

1: Recently, when starting the system, Avast has identified it as a new network, when in fact the laptop has always been connected to my Amplifi router, which connects to my ISP's ONT. I've told Avast it is in fact a private network, it's done a scan, found the usual stuff connected, said it's okay and I've shrugged and got to work.

Then today I thought I'd check my network settings, and lo and behold, I see this:




2: Then, also recently (but I can't be sure it was around the same time the problem described in (1) started) the DNS Client service hosts has begun using over 50% of CPU capacity for long (up to an hour) periods, bringing everything to a grinding halt. I've researched threads on here and elsewhere on how to try to fix that, but none have mentioned the first problem as also occurring.

The questions

1. Is this coincidence or are the issues related?
2. Do I try the fixes suggested for the second problem and hope the first will go away?
3. Or is there a fix which will deal with both?
4. And if not, how do I also prevent multiple connectors spawning without my doing anything to create them?!

TIA

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
