Enhance the PW of Network Cards

[ethical hacker]

The majority of Alfa network cards possess the capacity to produce 1 WATT of power in order to extend the reach of the Wi-Fi network card; however, they are typically not configured to do so by default in Kali. This can be adjusted by optimising the transmitting power of the card to its maximum potential, thereby amplifying our signal for optimal connectivity.

The drawback of elevating the transmitting power lies in the accelerated wear and tear on your Alfa network card, attributed to increased heat generation and energy consumption. Therefore, it's advisable to enhance the PW solely when essential, such as for executing an EvilTwin attack to facilitate easier targeting of devices connected to your counterfeit AP.
THIS DOES NOT FUNCTION UNIVERSALLY ACROSS ALL NETWORK CARDS!!!

1. This directive configures the region of your Kali system to Island. Different countries enforce distinct Wi-Fi regulations, and aligning our OS host country with Island enables us to surpass power limitations imposed in other regions. Some nations restrict channel operations, while others have more lenient guidelines. Tailoring our machine's country setting permits us to adjust settings accordingly. Additional optimal country regions include GY (Guyana), along with others such as Estonia, Costa Rica, and Switzerland.
Within Kali, access the Terminal and input the following command:

Code: Select all

sudo iw reg set IS

2. Here, locate your wireless card interface.
Type:

Code: Select all

sudo ifconfig

3. Search for "Tx-Power=" to identify the default transmitting power. Our objective is to augment this value.
Type:

Code: Select all

sudo ifconfig INTERFACE down
sudo iwconfig INTERFACE

4. This action will establish the maximum power output to 1W.
Type:

Code: Select all

sudo iwconfig INTERFACE txpower 30

5. Re-enter this command to observe the variance in the "Tx-Power=" setting:

Code: Select all

sudo iwconfig INTERFACE

6. Reactivate the interface.
Type:

Code: Select all

sudo ifconfig INTERFACE up
