This is my third worst bug i see on my newest version of kali
i'm thinking to download (1.0+,-2.0) instead cause all said its good for all i want
but i have an hope to fix it and i will post the the 2nd soon but by the way we here now!

I'm trying to change the txpower of my Intel Corporation Wireless 3160 (rev 83)
to 30 dBm
but whatever the number of dBm it won't work!!

root@kira:~# ifconfig wlan0 down
root@kira:~# iw reg set 00 # i'm trying 00 cause i can't get something else when i type iw reg set --debug
root@kira:~# iwconfig wlan0 txpower 30 # also tried iw dev wlan0 set txpower fixed 30mBm
root@kira:~# ifconfig wlan0 up
root@kira:~# iwconfig wlan0
wlan0 IEEE 802.11 ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:on

and i'm always in need to this command after startup in kali
iwconfig wlan0 txpower on

I have followed multiple posts in AskUbuntu, Null-byte and maybe Superuser too

but with no benefit and i started to think that current kali version is a really trash cause nothing interesting like cracking with my radeon gpu works in this system also...but yes we are in this bug now!

or even penetration testing on an iphone that i noticed they using kind of keep-alive packets that normal deauth attacks won't work for that i was in need to get more power plus other reasons like using airbase-ng on my AP but does that matters?

I feel like a restricted and thinking to code tools myself and that may be illegal, thinking again about how even i will change the txpower if i'm not even knowing what's the root problem or config file of that thing.
