Linux , monitormode and dhcp
 

how DHCLIENT effects monitor mode of my wireless card?

From some documentaries i came to know that its mandatory to kill dhclient process while entering in monitor mode..but there is no further explaination for his activity... from the command in unix termial:airmon-ng check wlan0

the following result is displayed Found 3 processes that could cause trouble. If airodump-ng, aireplay-ng or airtun-ng stops working after a short period of time, you may want to run 'airmon-ng check kill'

PID Name 583 NetworkManager 622 wpa_supplicant 1841 dhclient

how these things can make trouble at my activity?

dhclient/dhcp are about getting an IP address for you, which involves sending stuff to the router. Monitor mode doesn't send, but listens. I think it would be necessary to kill either of them.
