    I have two Macs that I use in my apartment on the same WiFi network. The network is made with my Apple Airport Extreme router.

    The problem is, on the iMac (2009), internet works perfectly. I checked on speedtest.net, it is just as it should be!

    On the Macbook Pro (2006), it is horrible. It may take up to half an hour to load a 4 minute YouTube video, a minute to load a page, etc.

    The WiFi connection on both is 4/4. I have done a software update for both of them recently.

    Please help,

    Thanks.

    :apple: 10.6.3 on both.


    I checked, on the iMac, the speed is 5.67MB. On the MBP, it is 0.16.
    It's amazingly horrible.

    There are other things to check, but just to note, it could be a hardware problem. Has any work been done inside the slow MBP? Something that might've knocked the antenna connection loose or something?

    Another thing to check: Open up System Profiler (either through the About This Mac menu item or in the Utilities folder), and click on the Airport item. See what the Signal/Noise ratio shows, and also what the Transmit Rate below it shows. This'll at least narrow it down.

    You can also try doing a ping test on, say, apple.com (or some other big, stable site) to see if you're getting packet loss or if the response time is weirdly slow. That'll further narrow it down.
