    Hi there cgfonseca1,

     

    I understand that you may be running into some DNS issues on your home network. I have an article for you about addressing this issue, and it can be found below:

     

    Non-responsive DNS server or invalid DNS configuration can cause long delay before webpages load - Apple Support

    Take care, and thanks for visiting the Apple Support Communities.

    Does this effect some web pages all the time, or do the web pages affected vary?  Do some web pages always work?

     

    Your MacBook Pro should be acquiring the DNS server address(es) from the local DHCP server on your local network.   That's usually a service provided by your ISP; a gateway-router-modem-firewall box of some sort.   That setting can be overridden locally for your network within your MacBook Pro settings (usually via the locations mechanism), or the DNS server settings being provided by the DHCP server might be wrong.

     

    In System Preferences > Network > Advanced > DNS, do the DNS server settings match what you ISP suggests?

     

    Or have those been overridden locally, and are referencing (maybe?) an office DNS server or two?

    You could experiment with different DNS servers, such as:

    OpenDNS.org

    208.67.222.222

    208.67.220.220

     

    Google DNS

    8.8.8.8

    8.8.4.4

     

    System Preferences -> Network -> Advanced -> DNS -> [+]

     

    If this improves things, it could be your ISP's DNS servers, or as is often the case, you home router acts as a local DNS server, forwarding request on to the ISP's DNS servers.

     

    So I would say, if substituting your own DNS servers makes things better, I would suggest power cycling your home router to see if that will get it to clean up its act (of course to test, you need to remove any system preferences -> Network -> Advanced -> DNS -> [-] entries).
