Airport connection on Macbook
Here's how it's acting right now: Network diagnostics show that it's seeing the n/w (and neighbour's networks) and show's that the Airport and Airport Settings are working (they're green) but the Network Settings are yellow. I've no idea why.
Strangely, he took it to another location and he said he was able to connect to their n/w fine.
I've tried the Ethernet connection and it works fine.
I reinstalled Snow Leopard just in case as I feared something got mucked up but that hasn't helped.
I ran the complete h/w diagnostics and they came back clean.
I'm at a loss as to what to do next.
Ideas?
Macbook, Mac OS X (10.6.1)
