Hi,
You the connection to your AP would be broken. As you've enabled monitor mode, the card will only receive and not transmit (hence it's called monitor :P).

Have you changed the capture type in the kismet configuration file (kismet.conf)? It should be like this -

captype=prism2

as your using a prism2 card (default is pcap AFAIK).

You are setting the card to listen on Channel 11 - Is this definatley the channel that your AP is operating on?

Perhaps if you post your configuration file we might be able to spot the problem ;-).
