Have a look at http://wiki.wireshark.org/CaptureSetup/WLAN : ----- <quote> ----- Capturing WLAN traffic on Windows depends on WinPcap and on the underlying network adapters and drivers. Unfortunately, most drivers/adapters support neither monitor mode, nor seeing 802.11 headers when capturing, nor capturing non-data frames. Promiscuous mode can be set; unfortunately, it's often crippled. In this mode many drivers don't supply packets at all, or don't supply packets sent by the host. ----- </quote> ----- Also when you try to capture all the traffic on the PC with the hard-wired connection, you won't see all the packets since the network is switched. Have a look at http://wiki.wireshark.org/CaptureSetup/Ethernet for more details on what traffic you are able to see on which type of network-connections. Hope this helps, Cheers, Sake _______________________________________________ Wireshark-users mailing list Wireshark-users@wireshark.org http://www.wireshark.org/mailman/listinfo/wireshark-users
