I'm really hoping that someone can answer this. It's very annoying to be able to connect to my home wireless network but not out onto the internet.
Can anyone point us to a definitive solution yet?

Bizarrely, it now works. Here's what I did, for what it's worth...
I removed all the network services, and then rebooted.
I then added the airport back, and tried to enter my local wireless network information in manually, using all lower-case letters for the network name.
When it couldn't find that, I entered in the correct name (with proper caps used) and it connected.
I have no idea if it was the reboot with no network services that did it, or if it was the attempting to join the network manually.
I will have to see if this lasts, if it's a lasting fix or not.
