Okay, I've tried everything that youo suggested and nothing has helped. I decided to try and update my software by plugging straight into the router with an Ethernet cable. After about a minute it dropped the Internet connection while it was plugged in. Airport was turned off at the time.

Thanks everyone for looking, I feel emabrassed to admit that I believe I have solved the problem by shutting off the firewall on the router. Don't know if I should feel frustrated that it took me an hour or two or relieved that is all it took.

I bought my first Macbook pro 13" with Lion yesterday.Was pretty excited about it, because I had saved for so many months to get this machine.
But when I tried to connect it to the WIFI (2wire Router from ATT) I just would not get connected. I tried for 2 hours but in vain.
Tried for the whole day today SADLY very frustrated now. With so much Hype and being so pricy, plus with so much focus on moving towards the cloud and all, I though getting online should be a peice of cake. Anyway.. Please suggest a solution. I have tried everything suggested in this forum. I am scared to delete any files though.
I am posting this message from my PC ha ha..

Still, there is no official word on this ongoing issue since 2007! 5 Years!
I mean it's as simple as a darned wifi connectivity hiccup! Fix it already!
All I see is "Connection timeout" and "Conection Failed" I am two dialogue errors away from smashing my MBP on the wall.. the irony is that I work at home via this thing called the internet!

I had the same problem and after 4 hellish days of messing with router settings, I have finally figured it out, and came back to this thread to share! I searched here (and everywhere else on the internet) yesterday for an answer, but although the information I found led to the fix, nowhere did I find what was, for me, the vital missing piece of information.
I have a factory reconditioned MacBook Pro that I purchased from the Apple site. It came running Snow Leopard, and I upgraded to Lion as part of my ridiculous quest to connect to wifi at home. Turns out Lion wasn't necessary, but nonetheless, I guess it's nice to have the upgrade. I have Uverse internet with AT&T, and we are using the 2Wire router that came with the system. It has worked with our other apple products and pc laptops at default settings no problem. The MacBook wouldn't connect.
I think MacBook likes WPA2-PSK security for some reason. We were set on WEP. So, go to this address - 192.168.1.254
That will take you to the 2Wire settings site. On the tabs across the top, click "Settings." Then click the "LAN" tab. Go down to the subheading "Security." By Authentication Type, drop-down menu to WPA2-PSK (AES). Then go to the bottom of the page and click Save. Now for the small detail no one has mentioned in my four days of searching for an answer. When your Airport recognizes the network and you select it, it will prompt you for a password. It is not the number you were using for your WEP security. For us, that was a 10 digit number called router access address. For WPA2-PSK, the password is the SSID #. I had to reset all the other devices running on the network with the same new password, and now we are all running on the network again. Thank the lord!!! Hope this helps save some poor souls from the hours of frustration I have just been through!

This is more for people searching on a similar issue.
My 2011 MacBook Air would connect to the work WiFi and network diagnostics showed green all the way. I could Ping as well.
I tried all the solutions offered up mainly setting up a new location and messing with DHCP. Nothing worked.
My iPhone could connect but the mac couldn't.
Here was my fix.
Open System Preferances.
go to TCP/IP tab
Select 'Using DHCP with manual Address' from drop down.
Type in an IP address you assume to be free.
My aging work router that I don't have access to was sharing out IP addresses, so I picked one for myself with a high number.
hope this helps.

Most likely you MAC filtering in 2wire is on. You need to add the MAC id of you Macbook to the "allowed" list or turn the MAC filtering off.
