    My Retina MBP had been perfect. Opens stuff up fast. My ISP speeds are around 50 down and 10 up. I usually use Chrome as my browser. Lately, I have been getting very slow in opening up different URL's, sometimes up to 10-12 seconds, where it had been 1-2 seconds. At the bottom of the left page, I would see the "resolving host" posted until the URL finally arrived. After trying various things suggested elsewhere, I unplugged my modem and my Airport extreme router. I waited about 30 seconds, then plugged my modem back in and waited until it had stabilized, then plugged my Airport Extreme back in. Voila, fixed.

    I have tried this and the problem comes back after a reboot.
    Any help would be appreciated.

    It sounds like a problem with DNS. You can try using a different DNS service, I recommend Google's:

    Go to your network preferences, click the Advanced button on your WiFi connection and then add the IP addresses in the DNS tab.

    Hope this works for you!

    Setting the AirPort Extreme to OpenDNS or Google DNS would work fine. Or set the specific MBP to one of the DNS providers...

    Essentially this is how it works. DNS is like a translator.

    Say your website you try to access is at, DNS then converts it to The faster DNS services are Google and OpenDNS. Some ISP DNS services are atrocious.

    Actually, it's the other way around. DNS translates the domain name into the IP address. One thing to keep in mind if you do use Open DNS or Google DNS - some WiFi networks will block DNS traffic to anyone but their defaults (usually places like airports ans some hotels), so you would have to temporarily change them back in those cases.
