What if you run

	sudo tcpdump

without a "-i" argument?  It will probably drop the wireless connection, 
so the problem isn't purely a Wireshark problem.

And what version of TShark are you running?  What does "tshark -V" 
print?  A version I have built from recent SVN source doesn't open wlt1 
if you run it with "-i en1", so that version shouldn't cause the 
connection to be dropped.
