# Alfa AWUS

# Set TX-Power 30

Three easy steps:

# Here it goes
```bash
root@kali:~# ifconfig wlan1 down
root@kali:~# iw reg set BO
root@kali:~# iwconfig wlan1 txpower 30
```

# This is what it looks before

```bash
wlan1 IEEE 802.11bg ESSID: off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr: off Fragment thr: off
Encryption key: off
Power Management: off
```

# This is what it looks after
```bash
after :
wlan1 IEEE 802.11bg ESSID: off/any
Mode:Managed Access Point: Not-Associated Tx-Power=30 dBm
Retry long limit:7 RTS thr: off Fragment thr: off
Encryption key: off
Power Management: off
```

----

mine is ```wlan1``` as internal is wlan0 yours may well be ```wlan0``` so just swap ```wlan1````for ````wlan0``` in your own setup.
