Trying to connect to a wireless network on an Mac, says it's connected and the signal is 'excellent' but there is no connection.

Is there something simple that i'm missing here?

No, you are not missing anything.

If the connection is OK - I am not sure where what says "excellent" on a Mac but you can see the number of bars in the menu bar wireless symbol - there's a number of other reasons why the internet wouldn't work.

Where is that wireless network and are you sure you have access?

Possibilities:

- Network has no or non-working DHCP server, you have to choose a fixed IP address.

- Network is locked to certain computers (by MAC address)

- Network is not connected to the internet (even though the wireless is up)

Newer Macs have a diagnosis tool, I think that started in OS X 10.4...

If you have a new Mac 10.4 and are using Safari, you can run a network diagnostic test. This will determine the status of your connection, and what you need to do to fix a problem.
