You are not changing the wifi pick up spot, you are changing YOUR DEVICE SETTINGS (ie, computer, router, phone, ipad, smart TV, fax machine...etc), you change it one time on whatever device you want (that contains an IP address)
Changing it how? From what to what? I have an iPad.
Mobile or other devices
DNS servers are typically specified under advanced wi-fi settings. However, as every mobile device uses a different user interface for configuring DNS server settings, we provide only a generic procedure below. For more information, please consult your mobile provider's documentation.
To change your settings on a mobile device:
1.Go to the screen in which wi-fi settings are specified.
2.Find the screen in which DNS server settings are specified.
3.If there are IP addresses specified in the fields for the primary and seconday DNS servers, write them down for future reference.
4.Replace those addresses with the Google IP addresses:◦ For IPv4: 18.104.22.168 and/or 22.214.171.124.
◦ For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844
5.Save and exit.
6.Test that your setup is working correctly; see Testing your new settings below.
