How can i solve IEEE 802.11 problem on wireshark
Hi everybody, i have a problem with IEEE 802.11 protocol in wireshark and i cannot see wifi traffic from my computer. I've install wireshark-gtk from AUR on arch linux. I use 2 network intefaces : 1 in monitor mode (for capturing wifi) and 1 in manage mode. I've compile the wpa_pwd like this : Mypasswd:MySSID but it not working, i've tried with wpa_psk but it don't work. I type there the output of iwconfig:
lo no wireless extensions.
eno1 no wireless extensions.

What i have to do to fix this problem ?
First step: don't try to capture in monitor mode with an interface that is also in managed mode. Suggest to dedicate an adapter to monitor mode capture. This might require any network managers that are running; if you have the aircrack-ng suite of tools, the airmon-ng tool can help provision the adapter for capture.
