I just received my new MBP today, and the first thing I did was
install Wireshark (via Macports, which works perfectly for me on my
current Powerbook G4)
http://www.macports.org/
Specifically...
http://svn.macports.org/repository/macports/trunk/dports/net/
wireshark/Portfile
The interesting issue is that as soon as I do a "> sudo tshark -i
en1" it kills my wireless association, and I have to reconnect after
the capture to get back into my Apple Extreme wireless connection,
all other devices on the network are unaffected.
If I run Wireshark under X it has the same effect.
Running " > sudo tcpdump -i en1 works fine as you would expect.
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 drivers for the "Pre-802.11n" Athereos chipset used in the
newest Macs??
