I have a 2009 MacBook Pro that won't connect to the Internet at my university while everyone is able to. How do I fix this?

My roommate has the same laptop as me and she connected perfect fine. I also was here last semester and I could connect with no problems at all. I came back to school this semester and suddenly I keep getting the exclamation mark saying I'm not connected. I'm also connected to the Internet on my iPad right now so I know it works. How do I fix this? Please help!

Try the basics first:
   Change your router channel number.  Most times this works & is all you have to do.
Disconnect & reconnect your modem.  unplug it for about 10 seconds.  Plug it back in.  Do the same for Apple’s routers.  Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

    You put the internal drive in an enclosure. If you choose to keep the drive, you don't need to erase it.

    my macbook pro says I am connected to the internet with a strong signal but it won't load any pages.  The internet works fine on my iPhone and other computers so it must be an issue with my macbook.  Any suggestions??

  • Macbook Pro suddenly will not connect to the internet via ethernet cable.

    I know this is a long shot... but I figured I would give it a try.
    My macbook pro suddenly does not connect to the internet via ethernet cable. Please bear with me, as I am not very tech-savvy - I will try my best to describe the symptoms!
    I connect to the internet via ethernet (we don't have wifi). It was working before I went to work, and when I came home I suddenly couldn't get anything to work (I know everyone says this, but I truly didn't mess with anything). Internet browsers just think for awhile and then turn up the 'You are not connected to the internet' error.
    I went into my network preferences and curiously, the 'Ethernet' shows a green dot and says 'connected'. However it says 'Authentication server is not responding' underneath the last part that says '802.1X: WPA: eduroam' (I think that is my user profile).
    When I go into my 'security' settings I can see that my firewall is off, so that shouldn't be causing any problems.
    I've tried restarting the router and computer itself many times. Diagnostics just gets to a certain point and reports back 'Network Diagnostics cannot fix the current networking problems.' I've also tried switching to a different ethernet cable, and I tried both cables out on a PC laptop and it connected without issue.  Additionally, I brought my macbook along to a friend's house and it connected to his wifi just fine, so the problem appears to just be with ethernet connections.
    I know it's hard to troubleshoot this kind of thing without being there and having a look at the computer yourself, but any tips wouild be greatly appreciated.

    As I mentioned above, I am not very tech savvy so I have no idea why a wireless protocol would be showing up there, I'm just listing everything I see in hopes that someone might know something I can try. This is why I am asking for help here - I'm not sure what has happened that has made me unable to connect, especially since it seemingly occured while nobody was using the computer.
    I guess I should clarify that I'm not a total hillbilly- normally my firewall is set to 'on', but I set it to 'off' to try and troubleshoot the issues here as I was told that sometimes it can interfere with the computer's ability to connect to the internet. If this is not the case and firewall does not affect anything, I will turn it back on while I try to fix this.
    I have tried the method you mentioned above a few times - I actually contacted my ISP earlier this week and they recommended resetting the router like that. They didn't mention any known network issues.

  • On my MacBook Pro when I am connected to the internet via an Ethernet cable, Facebook pictures do not load. They show up as white boxes with blue question marks.

    On my new MacBook Pro when I am connected to the internet via an Ethernet cable, Facebook pictures do not load. They show up as white boxes with blue question marks. This also happens on a website editor. But, when I am connected to the internet via Wifi, everything load properly. This is my work computer, so I have to be able to connect through the Ethernet cable to access everything. Please help me!

    I mostly use Safari. But I also tried it on Firefox, Mozilla, and Camino. Mac OS X. It's my work computer, so I've only tried it at the office. I have to be connected through the Ethernet cable to access my files and email on the server.

  • Apps on my Macbook Pro don't function/connect to the internet

    For some reason some apps on my Mac will not work or connect to the internet. The ones not working are: iTunes (can't connect to the iTunes store but I can play media I have locally), App Store, Safari, Beatport App, and Adobe Reader; but I wouldn't be surprised if there were more that I just haven't checked. Safari and Adobe Reader both open and function normally for about 5 second or so and then just freezes and doesn't respond. Everything else just says it's opening but never actually does and eventually stops responding. I also can't do software updates for iTunes or my Mac in general.
    I tried uninstalling Adobe Reader and installing it again from the Adobe website, but when I open the installer it doesn't respond either, so now I just don't have Adobe Reader installed anymore.
    I also tried disabling my firewall and messing with my security/network settings but didn't have any luck. Anyone have any ideas??

    Reboot into OSX, run Boot Camp, select Download Windows Support Software.
    While that is downloading you will have time to Print the Boot Camp documentation and read it (clearly you have not yet)

  • I have a macbook air that is not connecting to the internet correctly.  I've had it connected for three weeks, it went into sleep mode, and will not reconnect.  It will connect to other wireless routers (I've tested it) but not the one at my apartment.

    The problem is not happening with any other device that I have.  My iPad, iPhone and another laptop all connect fine.  In fact, it's not even the connection.  The computer will connect to the net.  It just will not open any page.  It starts to open and then hangs and hangs.  It will not move.  Weird since it worked great for three weeks and then all of the sudden, nothing.  Click on Safari and I have short hope that it will move and NOTHING!  Any thoughts why it would hang up like this and only with this specific network? 

    This is a known Lion issue, hopefully solved in 10.7.3. But may not be solved immediatly after updating, that was my case.
    To make it work i followed those steps.
    1.- Restart
    2.- Lion 10.7.2 Update
    3.- Uninstall netwokrs
    4.- Shut down
    5.- SMC reset
    6.- Reinstall networks
    I dont know whether all the above steps are necessary, but for me the update didn't work properly before SMC reset. (I am running a MBA mid2011)
    Hope it helps,
    Cheers

  • Macbook Pro will not stay connected to the internet

    It appears that I am not alone in this problem, but none of the troubleshooting is helping.
    There seems to be no trigger, but randomly 0-10 minutes the internet stops working on the Macbook.  Sometimes restarting the wireless helps, most of the time it does not.
    I know that my network/internet are working fine because all of our other devices stay connected with the Macbook drops.  Is there a easy fix that I missed?
    Thanks,
    Mike

    Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
    Step 1
    Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
    Step 2
    Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
    Step 3
    If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
    Step 4
    Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter  tab, if there is one. Uncheck the box marked
              Wake for Wi-Fi network access
    if it's checked.
    Step 5
    Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
    Step 6
    In the Wi-Fi settings, select
              Advanced... ▹ TCP/IP ▹ Configure IPv6: Link-local
    Click OK and then Apply.
    Step 7
    Reset the System Management Controller.
    Step 8
    Reset the PRAM.
    Step 9
    Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
    Step 10
    Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

  • Macbook pro occasionally fails to connect to the internet

    Hi...  A few months ago I bought a new 15 inch Retina display MacBook Pro.  it's the third macbook pro I've owned but the first with the following problem.  About 5% of the time, when I boot the computer it fails to connect to my home network.  While this is happening I will click on Network Diagnostics.  I will, one at a time, walk through the following screens of that diagnostic tool..
    Select Location...  Always shows my Location so I click Continue
    Choose network port configuration...  That always shows the correct Wi-Fi radio button selected so I again click Continue
    Select Wi-Fi Network...  It always shows my home network so again I just click Continue
    Then comes the interesting part.  The next screen that comes up is the one where you choose between DHCP or PPPoE.  The moment that screen comes up, first DHCP is already selected which is correct.  But more importantly the moment that screen comes up, the network connects and a new window opens up that says,
    Network Change Detected.
    Your network configuration has changed.  Click OK to proceed to the next step
    What could be wrong that prompts the system to fail to connect once in a while even though it seems to only need me to click through the Network Diagnostic without actually doing anything and when I get to this DHCP screen, boom it connects by itself???
    Any ideas of what's going on???
    thanks... bob...

    1. Power off the router. Unplug it from the wall. Wait a while.
        Plug it back to the wall. Power the router on. Wait until all the lights are lit properly. It will take a while.
        Restart the computer.
        Start up in Safe Mode.

    2. Deselect Proxies if selected.
        System Preference > Network > Advanced  > Proxies Tab
        Under "Select Protocol", uncheck any box if selected.
        Click "OK" then  "Apply”.

  • My MacBook Pro doesn't support external speakers or beamers After Mountain Lion 10.8 Update anymore. How can I fix this?

    The Beamer responds with an error message - No Input fount On HDMI Interface

    Download the latest version: Parallels Desktop 8.0.18483. Uninstall the one you have then install the new version. The uninstaller will either be in your Applications folder or on the disk image for the version you now have installed.

  • Spotify won't connect to the internet?

    At the moment, Spotify is the only internet-based programme on my laptop that won't connect to the internet. I've tried everything that usually makes it work, e.g. logging out of Spotify and logging in again, turning off the internet via my laptop and switching it on again and turning the internet off via the router and a plug... but nothing seems to be working at all. Spotify for Internet servers like Google Chrome work but not for desktop. Why?

    Spotify does the same here. Device Android HTC m8 mini 2.

    My hard drive has 70.93 GB available, yet when i have more than one internet tab open, i have to force quit google chrome because 'there is no more available application memory'. How can I solve this? I have a 2009 macbook pro running on 10.6.8. I have tried updating to mavericks through the mac app store but after it downloading for a day i got an error message saying there was a problem with the download. The same thing happens if i try to update itunes or the mac app store. After research, i have also tried repairing disk permissions, but every time they do get repaired the 'repair' button still appears, i'm not sure if it's because it was unable to repair the initial problems or if it just keeps detecting new ones.

    2 GBs is a minimum in which you can do many things, but not concurrently. Be very careful to not install third-party add-ons, limit the number of applications you choose to enter in Login Items, run as few applications concurrently as you demand.
    I would consider adding more RAM to your computer. Your model supports 8 GBs, so I would install that.
