Macbook Air will not connect to the internet via Wi-Fi or Ethernet? Any ideas why not and how to fix this problem?

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.

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.

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.

Reset the TC to factory and start again.
Use all SMB type names for wireless and base station.. Not apple type names.. this is more important since Mavericks.
I also recommend different names for the different bands.
So for example.
TC name.. TCgenx (I use whatever the generation number is for the x.. eg TCgen4 or latest one TCgen5)
WIreless name.. TC24ghz for 2.4ghz
TC5ghz for 5ghz
You can also set the channel manually.
If you still have issues.. start with no security and then if it fails to connect there is something seriously wrong with the laptop. Did you upgrade install Mavericks?? That can lead to driver issues.. I would recommend a clean install.

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

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 air will not connect to the wifi network

I recently had to replace my wireless network router and now my macbook air will not connect to the network. it worked fine with the old wireless router. Now, i get a "unable to join wi-fi network" message. The network ID (SSID) and password (WPA) are the same as before. I try to manually enter the password, but continue to get the previous message.
Any help in figuring out how to correct this problem is greatly appreciated.
Also, I have several PCs in the house that have had zero problems connecting to my wireless with the new router. What am I doing wrong?

Hi,
Ever since did the last airport utility update this has been happening.
I believe the airport utility update is solely a software update. Repair permission and repair disk (boot from your installation disk A) may help.
Other wise, http://osxdaily.com/2009/12/22/mac-wireless-problems-guide-to-troubleshooting-ai rport-wireless-problems-on-your-mac/ may help, too.
Cheers.

PowerMac G4 will not connect to the internet via ethernet

I am normally a very mac savy person, but I cannot get this to work...
I have an Airport Express connected to speakers, a USB printer and an ethernet hub, which is connected to a cable modem and also a PowerMac G4 via ethernet. There is also a wireless iMac thrown into the mix. All hardware has up-to-date software.
The wireless iMac gets online, prints and plays music wirelessly.
The wired PowerMac G4 will not connect to the internet via ethernet, it is killing me.
I have gone through all the settings and cannot figure this one out. I really appreciate all advice.
Thanks,
G4 Mac OS X (10.4.8)

Hi pradagirl,
Welcome to Apple Discussions!
Leaving the other peripherals out, tell us the connection sequence from the G4 outbound.
Also, you might gain more insight at the Networking Forum

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.

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 mac book air will not connect to the Internet

I have a late 2010 MacBook air which has been connecting to the Internet by wifi until very recently. It now connects to the wireless router but not the Internet, there is a alert saying there is no Internet connection. My iPhone and iPad both connect to the Internet so I don't think there is a problem with my Internet connection.

Ok then.
Would you like to give the forum some more details?
If not then there is very little anyone could suggest.

MacBook will not connect to the internet via ethernet cable anymore.

My MacBook apparently decided the other day that it no longer desired to connect to the internet through an ethernet connection; it still works perfectly through a wireless network. I am a university student and so there is wireless almost everywhere so it's not so bad, but I cannot connect in my dorm and it's becoming a bit of a pain. I have tried to connect through several known working ethernet ports and no matter what my computer thinks it's not even plugged in. It's even more strange because I just woke up one morning and it was no longer working. Everything else it totally normal, save this one little inconvenience. Any ideas?

So I'm having the same problem. I woke up one morning and my macbook's ethernet connection suddenly stopped working. For some reason It wont recognize the cable.... I have tried 3 different cables and theses cables work with my sisters PC so I know the cable is not the issue. Im also living in college dorms which seems to be a commonality with this issue. I've searched for answers all over and I really don't have the time to make it to the mac store anytime soon. My wireless works but it's not allowed in my college dorms for security reasons(lame). Please help!...
Apple needs to formally address this issue.

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.
