I have had my Macbook Pro since Mid-late 2009. Running current Lion version. I always use WIFI networks, never had an issue. About 2 weeks ago, when I connect to ANY wifi network, the computer connects, I go to Safari or Firefox, and the page will load for 3-5 minutes before the internet works just fine. If I stop using the computer, or am reading a page for 10 or so minutes, it will do it all over again. What is really strange is that I also run VMWare for work, and if I go right to the VM Ware Windows side, the internet works immediately every time- no delay. Why is the WIFI working on the Windows side right away, but taking 5 minutes to work on the Mac side?


Anyone that can help me would do me a huge favor!


Also- I have iPhone 4s, iPad 2 and 1 and they all work right away on all the same networks.





MacBook Pro, Mac OS X (10.7.4)

    Select  ▹ System Preferences ▹ Network ▹ Advanced ▹ Proxies. If any proxies are selected, deselect them, apply your changes, and try again. You must apply the changes before they take effect. You don’t need to disable passive FTP mode.

    Checked, nothing was selected. Any other ideas?

    Please read this whole message before doing anything.


    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.


    The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:


    1. Be sure your Mac is shut down.
    2. Press the power button.
    3. Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    4. Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).


    *Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.


    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.


    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.


    Test while in safe mode. Same problem(s)?


    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

    No difference. What is really strange is that my email works right away, if I have a software update, it'll download with no issues, but the Internet won't load on the Mac side.

    Launch the Terminal application in any of the following ways:


    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)


    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.


    ☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.


    Drag or copy — do not type — the following line into the Terminal window:


    curl -I


    Press return. You should almost instantly get several lines of output below what you entered, the first of which begins with something like this:




    If there's no output within ten seconds, consider that a failure. You can then quit Terminal. Post your results.

    Change your router channel.  Sometimes this is all you will have to do.


    Power cycling the router.  Read the router's user manual or contact their tech support for instructions.

    This has been happening at ANY wifi spot- my house, my places of business- everywhere. Works fine in VMware though.

    So does that mean you are not going to check out the links I posted for a possible solution?

    Are you getting the delay loading in the browsers?

  • marximus25 Level 1 (0 points)

    I have already spent hours on the internet trying to figure out a solution and have tried almost all of these issues. It really doesn't seem to be a router issue, as all the other programs (ie. Mail, software updates) that require a data connection work immediately. I am only having issues with internet.

    Yes, Apple's website is my home page and takes minutes to come up.
