Increase Wifi Signal Strength Tx-Power On Kali Linux

Requirements:
1. Wireless card (some wireless card cannot configure tx-power)
2. Wavemon (apt-get install wavemon)

Step by step Increase Wifi Signal Strength(TxPower) on Kali Linux:

1.type

ifconfig

and make sure your wireless network already detected and up.
2. Now let's check our wireless card default tx-power by running this command

iwconfig wlan0
the default tx-power of my wireless card is 20 dBm.

3. When we check the default signal quality through wavemon,

4. To change the tx-power we must turn off our wireless interface by running

ifconfig wlan0 down

and then change the regional to BO (Bolivia) which in that country they allow the use of 1000 mW tx-power

iw reg set BO

turn on the wireless interface again

ifconfig wlan0 up
