My macbook pro wont stay connected to the internet

So I have been having some issues with my wifi at college. I have to input my username and password to connect, which works, but then after a while my Internet just stops working. The issue happens randomly throughout the day and usually lasts a few hours. When it happens, it still says i am connected to the router, I just have no Internet service. Then if I leave it, it shows the little ! in the wifi status area. If i turn my wifi off, and reconnect it will work for a couple minutes, and then stop working and i find myself constantly disconnecting. So I was just wondering if anyone could help me. And i am using a early 2011 macbook pro 15", running the latest version of Mavericks.

  • My MacBook Pro won't connect to the Internet, but my phone and PC will.

    My MacBook Pro won't connect to the Internet. My iPhone has no problem doing so, and neither does my PC. I think it's something to do with my DNS, but I'm not sure. My network connections say that both my Ethernet or FireWire are failed. What's wrong with my MacBook? Is there a simple way to fix this?

  • MacBook Pro will not connect to the internet

    Suddenly, my MacBook Pro will not connect to the Internet--even when I take the cable from the Time Capsule and plug it into the laptop...
    -Internet is good
    –WiFi is connected
    -both work with my iPad...

    You should show WiFi:
    Do you have it turned on?

  • My MacBook pro will not connect to the Internet through wifi yet all other devices do

    My MacBook pro will not connect to the Internet through wifi. I have several other wifi enabled devices and they are all connected to the Internet just fine... What could/would cause this?

    Disable your AirPort and enable in a second. Or check, maybe you need to type in correct digits in; Settings/Network/Advanced/Configure...

  • MacBook Pro Won't Connect to the Internet

    Hi hi. Okay, I've noticed this unusual behavior in my MacBook Pro (Intel Core Duo, 2.4 GhZ, 15-inch, probabl 2 months old now) just last night. It connects to the wireless network but will not load any webpages. If I type in www.google.com or so, it says Contacting "www.google.com" and it stays on it and the page remains blank. I'm writing this from my MacBook which seems to connect fine to this wireless network. The problem persists in the MacBook Pro when I'm on XP (boot camp) and when I'm on Leopard. I've restarted the machine and everything but it still occurs. Prior to me discovering the problem, I think the MacBook Pro was asleep for 2 days (in XP).
    I've opened Network Diagnostics in Leopard and it detects the wireless network and everything but then it says it needs a WEP password. But the MacBook can join this same network without a password. I access the university network (from a dorm) so while you don't have to have a password to connect to the internet, you only log in when you open an internet browser and then sign in with the student ID (but its not the WEP password, if that makes sense). Basically, I can't acess the internet if I don't log into the internet and of course even the university login page won't show up. Can anyone please help me? It's driving me nuts. Thanks!
    P.S.- I've been hearing other MBP users having this problem but I don't know if I installed the Airport Update, and restarting doesn't help either.

    GStreakT:
    Your OS is shown as 10.4.7, but most people who are having problems similar to yours have later versions of Tiger or Leopard. If you're running a later version than 10.4.7, please update your settings for this.
    Some people, including me, have found that setting the router to "G-only" mode solves the problem (at least until Apple fixes the problem in a software release.) Please post a reply or email me as to whether this works for you.
    TIA

  • My Macbook will not stay connected to the internet, while my Dell computer works fine. Why? What can I do?

    My sister and I both have Macbook Pros that will not stay connected to our internet (wifi). Our dell computers and HP computers in the household work great- but both of the Macs do not stay connected, and often say "you are not connected to the internet". I have saved our wifi name to the computer so it is registered as our home network- but it still will not work fast or stay connected for long periods of time. Is there a setting I need to change, or anything I can do? Very disappointed with how the Mac works with our wifi.

    Mac's will have trouble connecting to WEP Encrpyted and/or "hidden" / "invisible " networks.
    OpenWEP (insecure) or WPA2(AES) is the only secure standard.
    ..WiFi, Internet problems, possible solutions
    WiFi security issues, at home and WiFi hotspots
    Also make sure the date and time are current and updating to Apple's servers for your location in System Preferneces > Date and Time. Then reboot and reconnect.
    If your still having trouble after this, take both machines back to the store for a free evaluation.

  • My Macbook Pro will not connect to the internet or bring up Safari!

    For the past couple of weeks my Macbook Pro has been having issues connecting to the internet and when it is connected it won't bring up Safari "You are not connected to the internet"
    I use the correct password for my wireless internet and it still won't connect. I deleted the airport in system preferences and then made a new one. It connected for a few minutes but then disconnected and just shows an explanation point over the airport sign at the top of my status bar.
    PLEASE HELP ME.
    I run a business and not having access to the internet on my Macbook is very very stressful.
    I brought the Macbook into the Apple store but of course it works perfectly when I bring it in there... HELP

    I also just realized it's also saying under the Airport status in System Preferences that the "AirPort has the self-assigned IP address ###.###.##.### and will not be able to connect to the internet."

  • My one-month old MacBook Pro won't connect to the internet?

    I called the service provider, it is neither our modem nor our internet. The PCs in the house work fine, but a couple housemates and myself own Macbooks, and although they find the network, they do not connect. I've heard it's just some problem that randomly occurs for Macbook users and has no actual solution other than luck. I was wondering if this is a false rumour, and how to go about fixing it? I've reset the modem, router, and computer multiple times to no avail.  If this is true, I will be the first one in line to sell my Macbook Pro back.

  • MacBook Pro won't connect to the internet after standby

    Hallo all,
    I have the following strange problem with my macbook pro:
    - after going in stand by and returning in operating mode the mac won't connect to the internet, I have to follow the procedure in order to retry to connect but It does'not work. Go in network preferences, try to change the DNS, use and not use DHCP and so on but nothing change.
    - Mac is working in ethernet, I can see other macs and pcs
    - When I change the network to connect, same problem even if I turn off the mac.
    I have the same problem with Iphone !!!!
    I have linksys router and modem but I think that the reason could be a setting in mac.
    Anyone can help me???

    I tried re-installing Mountain Lion 10.8.3 but it didn´t help.
    Assuming your can access email ok ?
    First, install the OS X Mountain Lion Update v10.8.4 (Combo)
    Then restart your Mac. That will reinstall any missing system files.
    Then try Safari.

  • My macbook pro will not connect to the internet via wifi or ethernet connection

    Hey guys just a few days ago randomly my 2011 macbook pro stopped connecting to the internet. My girlfriends macbook still connects fine as well as both of our iphones and my tv. Under network in system prefrences wifi is yellow and says self assigned ip, however ethernet says that it is connected with a green light but safari nor any other internet using applications will work. I even tried downloading google chrome from my girlfriends mac book and moved to my computer via flash drive but still no go on the internet. Please help me.
    -thanks

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac. 
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. 
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    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. 
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click the line of text below to select it:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' 
    Copy (command-C) the selected text to the Clipboard. Then click anywhere in the Terminal window and paste (command-V). Post the lines of output (if any) that appear below what you just entered. You can do that by copy-and-paste as well. Omit the final line ending in “$”. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}' 
    This time you'll be prompted for your login password, which you do have to type. It won't be displayed when you type it. Type it carefully and then press return. You may get a one-time warning not to screw up. You don't need to post the warning. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3
    launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}' 
    Step 4
    ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null  
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 5
    osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null 
    Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

  • My macbook pro will not connect to the internet, help pleaaaase?

    I have literally been to countless forums and nothing has worked. I restarted the router for the internet, but every other computer in my house is connecting to the internet just fine. I don't know what to do, and this is incredibly frustrating. Can anybody help me?

    When you see an exclamation point in the Wi-Fi menu, from the menu bar, select
     ▹ System Preferences... ▹ Network
    Click the Assist me button and select Assistant. Follow the prompts. You may get a warning that Wi-Fi is not available, that you're too far from the base station, or that you're using the wrong password.
    Assuming that you've ruled out those possibilities, click the lock icon in the lower left corner of the preference pane and authenticate, if necessary. From the Location menu at the top of the window, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.

  • My macbook pro won't connect to the internet. Tried everything? Please help ...

    Although both Airport and ethermet connection seem to be fine (green indication in network diagmostics) and all other computers in the house will connect to the net just fine, my macbook pro will not. I have reset the router several times, restarted the macbook, tried to remove airport, I have run all diagnositics, created new networks etc etc. 
    What happens is that during network diagmostics, airport and wifi settings appear green, while network turns yellow and stays yellow.
    When i go into the advanced network settings menu under tcp/ip, there is an ipv4 address as well as a subnet mask address, but nothing after router:
    All other macs in the house (e.g. my girlfriend's nearly identical kmacbook pro) show up the router as 192.168.1.1
    My settings are in Norwegian, so I am translating what i read on the screen - please bear with me ...
    Thank you for all your help!!!

    That doesn't mean MAC filtering is useless; it's just that it offers very little protection. It's like securing a door with a cheap spring lock -- it will stop some people.

  • Macbook Pro isn't connecting to the internet unless it's on the guest profile

    I recently purchased a brand new Macbook Pro less than a week ago and I've never been able to connect it to the Internet on my log in. This is my first Mac and honestly I don't believe it was worth the price since I can not use the Internet on it. The only way I can use the Internet is if the computer is on the guest profile. If the computer is logged onto my account the Internet stops working on all the other devices in the household(2 laptops, 2 iPhones, and 2 iPads). I've tried everything possible to fix this problem and nothing helps. The closest apple store is over 100 miles away so it is out of the question to go into the store. Any and all advice will be greatly appreciated.

    Your warranty includes 90 days of phone support. Call AppleCare. If you don't get satisfaction that way, return the unit for exchange or a full refund within 14 days of delivery.

  • Macbook Pro won't connect to the Internet anymore.

    I am posting on behalf of a friend.
    She has a MacBook Pro 13" Early 2011 model. She can connect to Wifi and Ethernet cables fine, But when it comes to using the internet it won't work.
    She tried Safari, Firefox and Chrome, and other software that uses internet connectivity doesn't work.
    We used different internet connections, restarting the Laptop but it wouldn't work.
    She upgraded to Mac OS X Yosemite, see it would fix the problem but again, nothing.
    The Odd thing about it is that she has two account in the MacBook Pro, The Other account being her sisters, does get internet connectivity and browses the internet with no problem.
    We made a new account and see if that would do the trick but still does the same thing. No internet connection.
    Any suggestions how to fix this?

    I tried re-installing Mountain Lion 10.8.3 but it didn´t help.
