Windows 10: Strange behaviour with Ethernet cable runnng on usb3 adapter

hi there,

to make a long story short, my touchpad with the pointer goes bezerk when i have the usb3 hub connected and i plug the internet via an ethernet cable.

the mouse (external) works fine - everything works fine when it's on wireless though.

If i plug the cable to the usb3 adapter BUT not into the router, the touchpad cursor is OK, just when you plug into the router and gets an actual connection, then it goes mad.

I cannot test with another router and Asus support suggested to try with a switch with i dont have, i tried with a usb3 hub - same thing happening - and i dont have any other usb to ethernet adapter to try.

This is odd and started to happen with this new connection we have which runs over the TV cable on coaxial.

The computer went into surgery few months ago for a battery change so might be related with that?

any ideas welcome - no biggie since wireless works very fast but still would like to use ethernet from time to time.

thanks,
Gabrio

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

 

Constantly disconnecting with ethernet cable

Hello,

Thank you for keeping us posted on the status of the issue.

I suggest you to check if rolling back the Ethernet driver helps to resolve the issue. Follow the below steps.

• First of all, Press Windows logo + R from keyboard. It will open
  RUN.
• Now type devmgmt.msc and press Enter to open Device Manager.
• You will see all the device list of your PC. Expand Network Adapters

Rollback driver

Double click on your Ethernet driver in Device Manager. Then Click on
Driver tab and select Rollback.

Important: If your drive is performing well and there is no error, Rollback driver button will be grayed out as an option.

If it still does not help, I suggest you to reinstall the drivers for the Ethernet driver and check if it helps to resolve the issue.

Note: Once you uninstall the drivers the Ethernet adapter device will be disabled and you won’t be able to connect to internet. So it is advisable to keep all the installer files as a back up in your hard drive.

Write to us with the results for further assistance.

Thank You.

 

Ethernet cable settings

Hi Campbell,

Thank you for writing to Microsoft Community Forums.

Please reply to the follow questions to get a better understanding on the issue:

• What is the model number of your laptop?
  
• Do you have a yellow exclamation on the network icon after connecting the cat 7 cable?
  

However, you can follow the troubleshooting steps from
Fix network connection issues in Windows.

Also, I suggest you to check the laptop manual or laptop manufacturer to know whether the Ethernet port of your laptop supports cat 7 cable.

Hope it helps.
