Hello everyone, after speaking to apple support and finding out they would charge me 49 dollars to try and fix this, I thought I would try here first, and keep my money. I have a 17" macbook pro connecting to a home internet connection wirelessly. The two other computers (pc) on this have no issues. I have full bars on airport but it says cannot open webpages, going into the network settings it says for airport that there is a self assigned ip address. I have tried removing the airport icon from the side bar part in the network settings and making it again, making a new location, powering off all the computers/router/modem and I cant get it to work and I'm really stuck. I went and got the new updates I was missing also.

If anyone has had similar problems and could offer some advice I would be very very appreciative.

You probably need to set your ip to dynamic DHCP.

I'm quite the novice on this stuff haha, how would I do that?

Are you on leopard or tiger?

Try typing this in your Terminal:

sudo ipconfig set en1 DHCP

I'm on leopard 10.5.2, i typed that into the terminal and it said a warning about improper use of the sudo command, then i proceeded and it said sudo:ip command not found

still having no luck, if anyone has any ideas they can think of thatd be great

Forget about the Terminal - doing everything on the Terminal is completely nerdy - you wouldn't catch Eric Cartman using a Terminal.

Click once on your Apple Menu and scroll down to: System Preferences...

In System Preferences, click once on Network icon - looks like a graphite crystal ball.

In Network, you should see that AirPort is the top selection on the left, is highlighted and has a green light next to it.

Now click once on the Advanced... button (look to the bottom right-ish of your Network window) - and a new window will slide down from the top.

Click once on the TCP/IP tab at its top.

Next to: Configure IPV4 - click on whatever button is there, and scroll down to: Using DHCP - and then click on the OK button.

You will return to the Network window.

Click the: Apply button at the very bottom right of the Network window, and then Quit out of System Preferences.

its already on using dhcp.

What is your Modem's IP Address ?

(It should appear in same TCP/IP window in Network, next to: Router - which is just underneath: Subnet Mask).

When you click the drop down on the Airport icon in the menu bar what does it say it's connected to?

I think that the router is where the problem is happening. I've got a sneaky feeling that you are not getting an IP from the router.

What router are you using?

Other things:

Turn off the router - turn off all the computers. Turn on the router and the Mac. See if you get a connection? It's possible your router is only set up to assign only 2 IP addresses.

ok so its set to using DHCP, then it lists this:
IPv4 Address: 169.254.41.5
Subnet Mask: 255.255.0.0
Router: *blank*

the modem ip is 192.168.0.100 i think but there is nothing listed next to router

it says "cats 2007" with a tick next to it on the airport drop down, thats the name for the network that the other 2 computers are working on, and its a d link di-624 router.

A 169 range IP address means it is not receiving a DHCP lease from the router.

You may be having problems connecting to the access point itself. When you connected to the access point, did you enter in a password?

Do you know what the D-Link's IP Address is?

See above in Post # 9.

Something like: 192.168.0.1

Just under Subnet Mask...

[AddIt: Have you ever connected the MacBook to the Router, via an Ethernet Cable?)

yeah 192.168.0.1 is the ip address, but that doesnt appear next to router in the network settings its just blank. and yeah i connected via ethernet and it worked, but i cant use ethernet here only wireless
