Macbook Pro won't connect to the internet. Help, please?

[hortaux]

I'm using a Macbook Pro with OSX 10.5.8, and all of a sudden it refuses to connect to the internet upon start up. Open Firefox--- and nothing. The Airport says it's connected, and I know the internet is working (my dad's able to get on, as is my friend). The Airport says it's connected to the correct network, too, and hasn't "forgotten" the WEP key--- so it should be working, except it isn't. It's done this a few times, but after refreshing the internet for about a half hour, it would fix itself, so I let it continue longer than I should have.

I've tried shutting the computer down and restarting, shutting the modem down and restarting (while simultaneously restarting the Mac). Nothing. And I even tried plugging the computer in to the router with an ethernet cable, and it STILL says it can't connect. I have tried repairing disk permissions, as well but this also did nothing.

I am very frustrated and would really appreciate some help ASAP. Thank you.

Are all the traffic lights green?

 

[hortaux]

Thank you so much for helping!

No, the AirPort Airport Settings are green

Network settings is yellow

and ISP, Internet, and Server are red

and I got a message about Do you use PPPoE or DHCP

and I... have no idea what that means, or which one my ISP might use. I have Verizon Fios, if that helps?

In addition, I have now run the diagnostics option to no avail

and the assisstant option says that I have "no IP address"

:/

Open up Network within System Preferences again and navigate to to the left hand blade. Highlight the option that you use to connect to the interent (Airport if you connect wirelessly) Do you have a 169.xxx.x.xx I.P address or a different one?

DHCP - Does your ISP provided you with a fixed I.P number? (If you do not know then probably not) I would imagine this is what is used for you to connect.

PPPoe

PPPoe

It says "self-assigned IP" under Airport in the lefthand blade. Does this help?

This means that you are not receiving an I.P address from your ISP. The next question is why?

Do you have any other means of connecting to your router? Another laptop? iPhone? Do you have an ethernet cable?

Yes, I'm on another laptop right now. And I have an ethernet cable, but when I tried to plug that in and connect it to the Mac, that didn't work either.

You may want to try removing all the trusted networks and re find them as needed. I had to do this to my MBP last week. Everything else I tried failed.

This suggests that its something amis with your MBP's hardware. This is very hard to diagnose over the internet, so the best way is to create a new user account on your Mac to see if this temporarily fixes the issues with your internet connection. If it does not then the next step is to carryout an Archive and Install. If it does fix the issues then hopefully it might be simple to fix.


Do you have the disks that came with your MBP?

Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.

Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.

I tried making another account, to no avail. Still can't connect.

And no, I do not have the discs (we got evicted, they went into storage, we didn't pay our storage fee--- long story no one cares about--- basically i don't have them. Sorry )

I'm sorry--- I know this is really, really dumb--- but how would I do this?

For Mac OS X 10.4 "Tiger"

1. From the Apple menu, choose Location > Network Preferences.
i did this
2. From the Show pop-up menu, choose AirPort.
i did this
3. Locate the pop-up menu next to "By default, join:". If this pop-up menu is set to "A specific network," this means that you upgraded to Tiger from Panther, and you should stop here and follow the Panther steps, above, instead. Otherwise, continue to step 4.
I couldn't find this "by default, join:" ???????

now I've done something wrong and I know it. airport has no location, and still no IP address and no anythign I am so frustrated and I'm sorry I'm so useless but I don't know what to do

this is what's showing up:

I think it refers to this screen...



Accessible by going:-

System Preferences > Network > Clicking Airport on the left > Advanced
Next highlight each network and select the minus icon.
