Actually, I've seen this happen on my MacBook Pro as well and I do not have KisMac installed.
I didn't have much time to search or do anything about it but I was going to mention this on the list, but looks like Mike beat me to it.

When running Wireshark the wireless network dies as  soon as you open  
a "List the available Capture Interface" window the wireless  
connection dies. The window shows the interface "wlt1",   "ifconfig"  
shows the en1 as inactive. Performing an actual capture on this  
interface shows the 802.11 beacon frames from my AP.

This is annoying as I often use Wireshark to capture on my en0 while  
remaining connected to my network via en1, but as soon as I open a  
capture dialog, my network connection drops.

Has anyone else seen this on Intel Macs? Or is it perhaps a function  
of the drives for the "Pre-802.11n" Athereos chipset used in the  
newest Macs??


'wlt1' is the passive wireless interface driver from KisMac
(see http://wiki.wireshark.org/CaptureSetup/WLAN), perhaps this is
getting activated when you bring up the dialog and is thus dropping
your en1 connection.
Do you have anything like KisMac installed?
