Hi Mary,

Please see the script in the attached text file which will change the TX value of your Alfa Card. This is not exactly what you want but you will surely find this useful. You can put this code in a whatever.sh file:

Hi Mary Drapper,

Making changes to the script is a difficult job, so please be careful.

Following script will help you do it.

Put this code in whatever.sh file.

Remember, max TX value with this script is 30.

 

#!/bin/bash
set -x
#  (C)opyright 2010 Scamentology
# This Script changes the TX Power for the Alfa Wireless card

    txpower_up="yes"                            # Raises TX Power for alfa Adapters
 txpower_value="30"                              # Value to raise alfa adapter to
    interface="$(airmon-ng | grep "RTL8187" | awk '{print $1}')"  # "eth0" "wlan0" "wlan1"

#__ Nothing To Change Below This Line _____________________________________________________________

#__ TX Power Increase for Alfa____________________________________________________________________
if [ ! $interface ] ; then echo "Alfa Card Not Found" ; /usr/bin/notify-send "Alfa Card Not Found" ; exit 0 ; fi
ifconfig $interface down
ifconfig $interface up
sleep 3
if [ $txpower_up == "yes" ] ; then
  alfa="$(airmon-ng | grep "RTL8187" | awk '{print $1}')"
  if [ "$alfa" == "$interface" ] ; then
      tx_status="$(iwconfig $interface | grep "Tx-Power" | awk '{print $4}')"
      if [ "$tx_status" == "Not-Associated" ] ; then tx_status="$(iwconfig $interface | grep "Tx-Power" | awk '{print $5}')" ; fi
      if [ "$tx_status" == "Tx-Power=$txpower_value" ] ; then
        /usr/bin/notify-send "$tx_status"
      else 
        iw reg set BO
        iwconfig $interface TxPower $txpower_value
        tx_status="$(iwconfig $interface | grep "Tx-Power" | awk '{print $4}')"
        if [ "$tx_status" == "Not-Associated" ] ; then tx_status="$(iwconfig $interface | grep "Tx-Power" | awk '{print $5}')" ; fi
        if [ "$tx_status" == "Tx-Power=$txpower_value" ] ; then
            /usr/bin/notify-send "$tx_status"
        fi
      fi
  fi
fi

exit 0

 

Hope this would address your problem.

 

Thanks,

Hello, Mary

Hope you are fine.

This script will help you change the TX value of your Alfa Card. To do this job follow the instruction below:
Put this attached code in a whatever. sh file
Chmod +x
Now change the taxable value to whatever you want .

Then run the script

Remember the maximum TX Value with this script is 30!

I also suggest you to check this website.
