Click Advanced and select the DNS tab. If there are any DNS server IP addresses listed there, write them down for future reference, and remove them from this window.
Select Use the following DNS server addresses. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference.
Replace those addresses with the IP addresses of the Google DNS servers:
For IPv4: 18.104.22.168 and/or 22.214.171.124.
For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844.
