I am running Mac os x 10.5.8 and am having the same problems as above. Wireless is connected but keeps timing out. Have tried every solution posted on this thread but none have worked. Please help.

Feel free to open a new question to get the most helpers on to your exact problem.
This tread takes way too long to load & read through, I think you'd be far better off...

I found a solution! I called Apple, and here's their instructions:
Turn off your modem/router.
Turn off your airport wireless connection.
Drag the System Configuration file to the trash (Hard drive > Library > Preferences > at the bottom)
Shut down your computer
After about 3 minutes or so, turn on your modem until it's powered up fully.
On your computer, (do this quickly) hold down Command + Control + R and turn on your computer and immediately start holding down P in addition until you hear a second start up sound, and then let go. It should work perfectly after this! Good luck!!!!

Might be weird, but deleting the Airport service, clicking Apply and then recreating it just worked. Macbook Pro (2008) suddenly decided to have full wireless connectivity, but Safari, Mail and a couple of menu bar widgets just could not connect. Thanks for the tip.

I had this problem this morning on my Mac Air and quickly fixed it (thanks to this Post).
I have Symantec Norton 360 on my Mac. During the evening my Norton license expired and at the same time my Internet access dropped. Both wireless and hardwire.
I diabled the Firewall - connection blocking - no effect.
I disabled Norton Confidential and IT WORKED.
I will take a wild stab and say it's an annoying bug. My other Mac didn't have a problem when the Norton service expired so, go figure.

I had a similar problem this morning.
I took the Apple o/s update and could not connect to the Internet after that.
When I read this post, I disabled Norton and could connect again.
I will need to dig into the Norton problem.

I was able to fix my problem with both a short term and permanent solution. Short term I disabled norton. Then when I had time I did a full uninstall of norton and then a reinstall.

I don't know if anyone has posted this solution, but it worked for me. Under System Preferences>Network, I clicked Advanced...then clicked the TCP/IP tab. Then I clicked, "Renew DHCP Lease." That did the trick for me.

I had the same good luck. I shut off Norton and immediately got on. Updated Norton completely and so far no problems. Makes one wonder what firewall all these Mac book pro folk are using ...

I have a similar baffling problem.
New Mac mini with Windows 7 and XP on Parallels.
Invariably when I click a link, after a Google search for example, I get the cannot connect error.
But copy and paste the link into IE I connect!
Could it be a Lion glitch?
