I have a USB modem WL-167G V3. I want to switch to monitoring mode through airmon-ng, but it gives out that I need to kill the processes. The problem is that I want to leave the second interface connected to wifi, so you can't kill processes. But, even if I kill, the problem does not go away.
sudo airmon-ng start wlxf46d048b73f2
Found 2 processes that could cause trouble.
Kill them using 'airmon-ng check kill' before putting
the card in monitor mode, they will interfere by changing channels
and sometimes putting the interface back in managed mode
