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

Hi, I have had my mac for at least 5 years now and have had the same EXACT problem for about a year. I have figured a way to temporally fix the problem: in safari click network diagnostics then click airport then your network name then you type in your password and if it says that anything about your network has changed you have to click start over and repeat the process all over again. I know this isnt the best solution but I have learned to deal with it. Hope you fix your computer!

Does Network Utility also Ping OK? How about Traceroute in it?

Go to network preference>advanced>tcp/ip> use DHCP With manual ip , assign any random ip like 192.168.1.250

Thanks bsorense,

You saved me...

This is what he suggested:

I finally got this MacBook back on by changing the computer name: System Preferences - Sharing - Computer name.

Time lost over this issue is painful for me. The first two weeks with Lion, Wi Fi was fine. Not even slow. That was both before and after installing the 10.7.1 update. Then one day I turn it on -- after the system's been set for a week with no installs etc., and boom can't get to internet. Power cycled a few times. Started some trouble shooting. Tried dubious stuff from the boards like pram and smc reset . . .

I have tried everything, even calling. And here's the kicker!!!!!!!!

I can open Parallels, with WinXP simulated and go on the net with Firefox -- not cahced sites-- it's emptied on exit. I can do new searches etc. I've never done and the web responds. Go over to Lion and Safari, Firefox, even SoftwareUpdate all complain. Then I use the apple network diagnostic -- all fine it says.

So on this home wi fi, I have a PC, working with internet just fine. And I have a Mac running Tiger -- also working just fine with the internet.

LION is clearly having issues. I just hope they figure it out for the next release -- and send me a cd or something, although I guess I could download a fix through parallels here and move it over and run it on the mac side.

Anyhow, I'll add that I logged onto my router -- it sees my machine (which I figured since winxp on parallels inside the mac can get to the net), and its IP add and MAC add agree with what I have in Network Preferences. I opened terminal and I can ping my router. I checked security logs and found request, offer, ack, nothing too fishy looking (time zone was set wrong though).

Anyhow I thought at first I was just unhappy with iCal in Lion. Now I know a greater misery.

AppleCare / customer service wanted to push me off to the ISP. But when I've got a mac on Tiger and a PC and a virtual machine within the troubled Lion machine that can all surf fresh pages, and I can connect to the router at 192.168.x.x and ping it, well, does that really say ISP problem?

At least I don't buy beer via the internet 🙂

Both seem fine in Network Utility too (for sake of space just IPs are posted. URL was also + result):

Your method worked too for me! Thank you, thank you!!!! However -- a note for those on OS 10.6.8 on a Macbook Pro... when you follow Jessiemarieee's instructions, after rebooting the modem and while the computer is turned off, hold down all 4 keys at once (command, control, R, P) as you press the ON button. It will go to the regular blue screen with all the icons and you can let go of the buttons. Click on the wifi icon at the top of the screen, select your network, and once it activates, you should be good to go!!

Hi Mich,

If nothing here works, you'd likely get more helpers in on it if you start a new question.

Open Network Utility, see if you can Ping this IP...

Did you delete the System configuration folder from your trash before you restarted it?

My problem originated when I migrated the user from an older Mac to the new Air. I just started a new user with the new system and brought over files as I needed them, and everything worked fine.

Hi mayfi --

Welcome to Apple Discussions!
We're other Mac users here, asking questions and sharing solutions.

You said: +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.+

So, there's something amiss in your network at home, eh???
I've asked for more help for you . . . Hang in there!

I have a similiar problem. After installing 10.5.4 from a dvd the wireless connection didn´t work anymore. I tried any of the suggestions made in diverse forums( pref delete, airport delete, keychain new, resetting the router, changing channels, opening the network without a password, trying the assistant9 even rang up apple hotline but nothing worked. So finally i installed again 10.4.6: no problem. After that I reinstalled from the dvd, this time without deleting the old system prefs: no connection via wlan. ethernet works , the imacs, the other mac book, the iphone and the ipods we got have no problem either- only the one mb with leo. Any idea perhaps concerning some terminal issue?
