My Mac Air has been working perfectly for the ~5 months I've had it. I have a network at home, wireless with Airport.

When I came back after lunch today my Mac Air had frozen completely (which it's never done before). I held in the power button for a while and restarted it. When it came back on, and for every restart since, it can't connect to internet anymore.

I've restarted my modem and my Airport but there's no change.
I can see my network in the list of networks and it seems to connect fine but I can't reach internet.

What's up?
Greatful for any help.
