Hello,
I switch my wlan interface (interface for USB/ Realtec 802.11n WLAN adapter) to monitor mode with the following commands:
sudo ip link set wlx74da38e2f0fa down
sudo iwconfig wlx74da38e2f0fa mode monitor
iwconfig says that this was successful:
wlx74da38e2f0fa IEEE 802.11 Mode:Monitor Tx-Power=20 dBm
Retry short limit:7 RTS thr=2347 B Fragment thr:off
Power Management:off
However, I cannot find the device in the device list of Wireshark anymore!? How is this possible?
I use Linux Mint 18.3 'Sylvia' "Cinnamon 64-bit"
Thanks a lot, iago
