I have seen a couple of other people with this issue but their solutions were not applicable (Defender issue and Windows Update needed.)

I have checked Windows Update and it tells me I am up to date. I have turned all defence off for a couple of seconds and doesn't help.

I have a Windows 7 machine which I have used the same USB network card with and works perfectly.

I then tried pinging from both machines and realised that the Windows 7 machine is using ipv6 while the Windows 10 machine is taking more than twice as long using ipv4.

Then using the command prompt I tried:

ping -4 www.bing.com

ping -6 www.bing.com
Ping could not find host www.bing.com. Please check the name and try again.


Using your support pages I tried the following with the following response:

netsh interface ipv6 install
The following command was not found: interface ipv6 install

I then tried:
ipconfig /renew6

which claims to work but I get the exact same ping responses to -4 and -6.


My windows 10 is unusable on the internet. What is the point of having it?


Anyone have any ideas?
