Tx-power= 0 dBm on wlan0mon when monitoring; but Tx-power = 20 dBm on Wlan0 when managed. Help!
Hey everyone!
I have an issue trying to set my power to 20 when I'm monitoring. I'm using Kali lastest version from a Live CD (USB) and as chipset a Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter built-in my laptop to monitor. So here is the info:
iwconfig
sudo iw list

BUT THEN... when then i try to monitor here is what happens
airmon-ng start wlan0

Found 3 processes that could cause trouble.
Kill them using 'airman-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

(mac80211 monitor mode vif enabled for [phy0]wlan0 on [phy0]wlan0mon)
(mac80211 station mode vif disabled for [phy0]wlan0)
then i kill those processes and then
iwconfig
Power goes to zero. Any idea how I can fix it? I believe this is the issue why ii dont get any BSSID when I use after listening for a while with
airodump-ng wlan0mon

Nevertheless with I switch to manage mode everything is ok and it gets connection to my test wifi: Ever's House. So what I can do to fix this? Thank guys!
