Problems connecting to internet via BTVOYAGER

Hi all,

I'm having a problem connecting to the net via my Macbook Pro. I have the WEP key for a neighbour's network connection, which I've paid him to use. But...when I try to access email or the net, the browsers say that I am not connected.

Airport has a tick next to the connection and says that I am connected. I have not entered any username/ password information, as I don't have this.

In windows I know that a WEP key is sufficient to use the network to connect to the internet...

The router that my neighbour is using is a BT one.

Any ideas? All help would be appreciated.

I have been told when clicking on 'network' in system preferences that i "may not be able to connect to the internet", despite being connecting to the wireless network. this doesn't make any sense to me.
