Open System Preferences>Network. Click on Airport and then Advanced. Locate the problematic network in the window that opens, highlight it and delete it (via the "-" sign.)
Apply the change and close network preferences. Now see if you can't re-connect to the wayward network...
Hope this helps.
To test my understanding: I deleted my Airport network as you described, but it remain connected to the "wayward" network. I then selected a different network (so many show up I can barely believe it), and then switched back to mine.
Same result. Full strength, but no internet.
Just to clarify, the problem is not in connecting to the network, it is that for some reason, the MacBook can't see the Internet, even though it could this morning, and the G5 (from which I write this reply) can.
Fixed it myself....
All it really took was for me to reset the cable modem and the Airport Extreme. Turned off both the cable modem and the AE, waited 30 seconds, plugged in the cable modem, waited for the lights to go, then plugged in the AE. Worked.
Now it dawns on me: this is the same procedure I followed with my old network (non Apple wireless modem/router) when I was having this problem, except then, the problem was in reverse: the MacBook would see the internet but the G5 wouldn't.
Oh, now I have a sinking feeling I'll be doing something like this a lot more. Any input on what I should do should I see this happen again (and again)?
