As the docs say, monitor mode conflicts with normal mode, and will prevent your card from working normally while it is active.

Modern versions of Kismet (you should be running 2010-07) combined with modern drivers create a virtual interface (wlanXmon). Normal network connections will still be disrupted since the channel will be changing rapidly, but it will not change the interface type.

As Kismet says when you exit, you need to reset your wifi networking, depending on your distribution.

There is no way to capture the data kismet captures without placing the card in monitor mode. You can run tcpdump on your wifi card, but you will not see wifi packets, only the data packets destined to your system.
