Wireshark Brings Down the Network?

Tuesday May 13, 2008

I'm writing some network related codes now and would like to use Wireshark to see what's going on.

It's strange that anytime I start wireshark (using "sudo wireshark" to see the NICs) and press the capture button, the wireless network is brought down. The wireless menu icon goes gray, and when I try to reconnect, it reports a failure. However, I can turn AirPort Off and turn it on again to connect to the network again, and Wireshark works fine.

No idea why. I'm using Mac OS X 10.4.11 and Wireshark 0.99.7 with libpcap 0.9.4.
