MacBook won't connect to the internet!!!

I recently switch wireless service at home to At&t.

Since, my computer "connects" to my network, accepts my password, and shows full signal, but when I open Safari, or any other app that requires internet, I just get the "failed to open page because you are not connected to the internet" page.

My roommates connect to use our wireless network with their PC's just fine, and my Mac connects to other wireless service at school and work and works just fine.

I have been on the phone with At&t many times trying to troubleshoot and fix the problem. No success.

Apple charged me $49 to talk to them, with no success.

I HAVE ALREADY TRIED RESTARTING both my Mac and my router, I have reset the router, I have restored original settings in both Safari and my router, I have tried removing the security from our network in order to connect without a password, I have tried re-configuring the router to work with Macs....all no success.

I am very frustrated with the situation as I, like most people, require internet access for both school and work.

Any help, tips, or advice on the situation would be grateful.

Thank you.

MacBook, Mac OS X (10.5.8)

Wow. Same problem. Like often happens when a Mac quirk shows up I just wasted hours of my life and finally got it to work. I'll share the steps I took. First it worked two days ago at the same coffee shop, the only thing that had changed was the password, however no matter how many times I entered the password in the different forms. Nothing. All I got was a not connected... due to the "self assigned IP address" message. I attempted the tricks that people posted here: 1) Turned off and back on the wi fi ... nothing 2) restarted the computer... nothing 3)I went into System Preferences > under TCP/IP I changed the Configure IPv4 to "Using DHCP Manually" and used an IP address close to the one from my other mac which was connected just fine... almost nothing... the green light went on and it said connected under wi fi in the left panel of the preferences... but no actual connection 4) I changed the Manual IP address to Match my working Connected Mac... almost nothing... the green light again went on and it said connected under "wi fi" in the left panel of the preferences... but no actual connection 5) I deleted "Wi Fi" from the left panel and recreated it using the + and - buttons on the bottom of the left pane and hit renew DHCP address, but it recreated the same 162... IP as before and still not working 6) I changed the from a 162... to a 192... nothing 2) I hit Renew DHCP Lease... nothing same IP.

Then...

Here's what finally worked: Again in System Preferences>Network> I turned Wi-Fi off, Went to Advanced>TCP/IP>Configure IPv4 and changed it to off, hit "OK", Highlighted Wi-Fi in the left column, hit the - sign on the bottom left, deleting it, then hit the + and created it. I got a message saying there is no assigned IP address so I went back into >advanced>TCP/IP and turned on Using DHCP, Hit "Renew DHCP Lease" and it finally created a brand new IP address 10..... and if finally F'n worked.

Jeez Apple get it together. This is a ridiculous problem.

I hope my struggles actually help someone

Can you ping IPs out on the internet, but not URLs?

Like 74.125.53.103, but not google.com

I tried all the precedent solutions but nothing worked for me.

So, I went in my router panel and i switched the router's channel from 6 to 1, this solved my problem, hope can solve yours.

I was having this problem at work but not home. I fixed it by turning off File Sharing in the Sharing screen of Preferences. I'm thinking that it's some sort of security thing with the company WiFi. Now if I could figure out how to do the same for my iPhone4 I'd be all set...kind of maddening because a colleagues iPod Touch works fine.

Cheers.

This is a bigger issue than many realize, I have 2 macs, 2 iphones, an ipad and an HP laptop plus a wireless canon printer that is wireless. I get all wireless access dropped for all devices. The only fix and it is termporary is to reboot the router. sometimes turning off and on the devices wireless connection (iphone etc.) brings it back up but as soon as more than one device connects I lose connection and have to do the off on trick. It eventually gets to a point that the ATT router has to rebooted. I am on the 3rd router from ATT and have a tech coming out to attempt another repair. If I keep all mac products off the wireless then there are no issues. In addition all of my wired connetions are unaffected by this isssue. I have also attempted a static IP scheme and no luck there. It seems to be a 2wire/Apple conflict. I have not had any isssues with other brands in mixed environments.

Ultimately if Apple and 2wire could get together and resolve this that would be great!

update to my previous post, with a static connection and DNS entry I am able to connect to internet. As soon as I go back to auto DHCP the IP is self assigned by the apple device and no internet. The static IP is a band-aid fix and you will have to switch back to auto DHCP for other networks.

Ok, after reading ALL of this, and trying all of the solutions offered here, and many others from the web, I came up with a workaround for my machine. NONE of the suggested fixes worked...deleting files, changing PW type in the router, manually assigning IP addresses, etc., etc., and in fact I *STILL* cannot login directly to my router, so this is STILL a HUGE issue! If I try to hit the router directly, I still get the dreaded 'WiFi has no IP address' error and it self assigns. The last contact with the internet according to the logs was at 3:03 AM local time (GMT+7) this morning Mar 21, 2014, so it definitely was not something *I* did. I looked for a log listing update installs, but could not find one, so I have no idea if an update caused the issue. It worked fine for the last two years with no issues, so why did it suddenly quit working at 3:03 in the morning? A good question for Apple!

My workaround: (definitely NOT a solution)

I have a TimeMachine, and set it up to be a wireless base station. Easy enough, but you have to watch the IP's. It will probably assign an IP outside the range your router is set to. My router, like many, is 192.168.1.1, so I changed the IP address of the TimeMachine to 192.168.1.2 from 169.something and assigned the network range from 192.168.1.3 to 192.168.1.200. So after twelve hours of reading and trying many different things, always getting more and more frustrated, a half hour was what it took to make a workaround. My MBP can now get on the internet! WOO-HOO!

However, it is scary how many people are having this issue, and it would behoove Apple to figure out what the REAL issue is and fix it!!! I am pretty technically proficient, but I cannot imagine if my wife were trying to solve this problem! It does not normally take me 12.5 hours to solve something, or figure out a workaround, which points to how nasty this issue is!

removing airport and adding it back in worked for me. nice trick

Nov 19, 2011 12:59 AM in response to BDAqua

Thanks, I actually figured it out. I was doing the delete airport from the list trick wrong. You have to click apply at the end, after hitting create, then the little light turns green and it works!

Jan 22, 2012 1:15 PM in response to BDAqua

Yes, it was the DNS entries. I entered both; it solved the problem.

$49 ? - we'll do it for 1/2 that 😀

Let's start with System Preferences-Network... is airport at the top of the list on the left, with a green indicator, and says 'connected' - or does it say something else ?

Thanks, Mich!

I tried everything, including the popular Deleting AirPort, then recreating, which seems to work for a lot of people here. I tried your method--with high hopes since, like yours, my problem seemed to appear out of no where as well. It didn't work. I was about to give up on life.

But then I remembered to actually permanently clear out the trash! Then restarted yet again for good measure. And voilà! Life is good again! :)

Here's a solution:

try disconnecting from the network and then go to "join other network" in the wi-fi menu. type in the name of your wi-fi network and type the password (you also need to tell what type of network security your wi-fi has). Hit the connect button and it should work.

Was having this problem with my apt building's Wi-Fi. Could see the signal at full bars but kept getting an error stating that "Wi-Fi has the self-assigned IP address 169.254.201.82 and will not be able to connect to the Internet". Selecting the Manual DHCP and typing in the IP address I was getting when the connection was working immediately fixed the issue.

Thanks Toon61
