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...

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.

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 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 Macbook Pro will not connect to the internet.

Randomly, my Mac stopped connecting to my wifi network 2 days ago and now it will also no longer open safari or other internet based apps.
My network icon is always 'searching'. I can find my network occasionally and the status will be connected, but the icon remains searching and no internet is let through on to my mac.
I've tried the usual diagnostics but it replies my password or network name is wrong although it is correct. When I look in 'airport', nothing is found. No addresses are in my TCP/IP information, nothing in my DNS tab, no proxies boxes selected.
I have powered down my mac and routed numerous times and turned wifi on and off no end. All other apple hardware connects well.

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 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?

My MacBook pro will not connect to the internet, be it via the airport or ethernet at any location.

I have been on the phone with tech support, and have been to the Apple Store 3 times already. Each time I have brought the computer to the store, the internet will work. The workers say the store is 'magic.' However upon leaving the Apple store, the internet will not work be it at Starbucks or home. On my last visit to the store, they backed up everything on Time Machine, cleared the computer, and reinstalled OS, but I still cannot connect.
I'm at my wit's end and could use any help available. Thanks!

Turn off your Firewall, to eliminate that as a problem. System Preferences > Security > Firewall
Check to see if the router you are plugging into doesn't have MAC filtering activated.
Make sure your IP is not the same as another computer or router on your network.
If you have manually put those details in, see if you can set it to "Using DHCP"
System Preferences > Network
Are you using a Proxy? Make sure that is turned off in Advanced.
Is firefox / Safari in the Preferences under Advanced & Network - set up correctly?

My macbook air will not connect to the internet due to a self assigned IP address. I have tried trawling the support forums, but either I can't understand the suggestions, or they don't work. Please explain to me in simplest terms how to fix this. Thanks!

MacBook Air will not connect to the internet

I am trying to assist my wife with her Macbook air (MbA), it will no longer connect to the "internet". BACKGROUND: I am running Century Link DSL Modem, with a Belkin Wireless router. I have about 10 different nodes on my home network, PC, Apple and Droid devices. All of which have no issues with access to the internet. My wife's MbA however will not access the web, it does however connect to my network and get a DHCP assigned IPv4 Address from my network. I am able to go to addresses and inside my network and serve up http such as my router's web page. WHAT I HAVE TRYIED: I have flushed/removed all previously connected wireless networks on the MbA and turned off wireless on the device then shutdown and restarted it and reconnected to my SSID (wireless network) = no joy, didn't work. I have rebooted all of my network equipment = no joy, didn't work. I have changed the DNS to an address outside my network = no joy, didn't work. I don't know alot about Mac/apple product, they seem simple and straight forward, and I have been a cisco routrer/switch jockey for about the last 7 years of my carreer.... this one stumps me. Any ideas? Firewall configuration, is there a "intranet" only box checked somewhere?
PS... I may have miss spelled my words, human communication matters, spelling is over rated.

Power down the router. Unplug the cord from the wall. Wait a while.
Plug the cord back in. Restart the router.
Wait until all the lights are lit up properly.
Restart the computer.
Best.
