Hard to access Google related website

Question

Recently, I am experience slow access to Google related website. Whenever I visit a google related website, it take very long time to load. Then, I found out it is because my PC is hard connecting to Google sites. So I try to ping google.com from CMD, it shows Request timed out.

If I unplug my network cable and re-plug again, everything works fine. Ping to google also works fine. However after several minutes the problem occur again. And this only happens on my PC while other PC on the same network works fine.

Also, I found out that when the google IP is IPV6 it will fail. When the IP is IPV4, then it will success.

Pinging google.com [2404:6800:4001:807::200e] with 32 bytes of data:

How can I fix it?

Answer 1

It seems like your problem is with badly configured IPv6.

If you want to properly configure IPv6 you would need to provide more details or talk to your network administrator or ISP (depending on if it's a home or work network).

My recommended work-around for now would be to install the "Prefer IPv4 over IPv6 in prefix policies" from Microsoft which would try IPv4 before IPv6.

If that doesn't work you can try the "Disable IPv6 on nontunnel interfaces (except the loopback) and on IPv6 tunnel interface" from the same link.
Please note the first way is preferred so you still have ability to connect to IPv6 networks in the future.
