This guide contains three dissimilar methods to growth your TX Power or Signal Strength of your Wifi Wireless card. It besides includes 2 ways to brand those changes boot inward at boot fourth dimension hence that y'all tin bask the extra ability every fourth dimension y'all boot into your Linux distro.
The default TX-Power of wireless is ready to twenty dBm but y'all tin growth it amongst a footling fox to xxx dBm but allow me warn y'all start that It powerfulness live illegal inward your country, hence purpose it at your ain risk. Moreover Some models volition non back upward these settings or wireless fleck may province that it “can” transmit amongst higher power, but the device’s manufacturer belike did non house the appropriate oestrus sink inward guild to accomplish this. Readers MUST purpose this guide knowing what is allowed or non allowed inward their country. Author is non responsible for whatever activity taken past times a reader.
3 simplest options for you..
Option 1
Open lastly together with re-create glue the next commands:
iw reg ready GY
iwconfig wlan0 txpower 30
If higher upward method gives the next mistake together with hence become for Option 2.
Error for wireless asking "Set Tx Power" (8B26) :
SET failed on device wlan0 ; Invalid argument.
Option 2
ifconfig wlan0 down
iw reg ready GY
ifconfig wlan0 up
iwconfig wlan0 channel 13
iwconfig wlan0 txpower 30
Options 3
Copy glue the next commands into a text file together with relieve it equally IncreaseWifiTx
You powerfulness desire to edit regions to your likings. Link to basis regulatory domains are at the bottom of this post.
#!/bin/bash
echo "hello, root!"
echo " taking downwards wlan0"
ifconfig wlan0 down
sleep 3
echo "setting Region to Bolivia"
iw reg ready GY
sleep 3
echo "setting TxPower to 30"
iwconfig wlan0 txpower 30
sleep 2
echo "starting wlan0"
ifconfig wlan0 upward
echo "pulling wlan0 interface up"
iwconfig
sleep 5
echo "good bye"
Now do
chmod +x IncreaseWifiTx
./IncreaseWifiTx
Important FIX regarding region
Following is taken from a reader’s comment.
Hi everyone, y'all read this hither start !! Greetings from downwards nether =)
It looks similar the folks inward accuse of the linux wireless regulatory database cause got institute the BO (Bolivia) hack everyone is using, hence they ready it dorsum to Tx-Power=20 dBm equally of mid 2014. New 2015 KALI kernels are forthwith including this limit.
See for yourself:

So, what tin nosotros do? You tin edit the rule database which is a hurting inward the ass, or simply pick unopen to other region.
Try BZ (Belize) or GY (Guyana) equally a backup excogitation =)

(2402 – 2482 @ 40), (30)
(5735 – 5835 @ 80), (30)
country GY:

(5735 – 5835 @ 80), (30)
Enjoy!!
PS. For the Aussies out there, worth pointing out nosotros are getting ripped off. Those buggers across the ditch are getting 30dBm
country NZ: DFS-FCC
(2402 – 2482 @ 40), (30)
(5170 – 5250 @ 80), (17), AUTO-BW
(5250 – 5330 @ 80), (24), DFS, AUTO-BW
(5490 – 5730 @ 160), (24), DFS
(5735 – 5835 @ 80), (30)
=P
Setting changes automatically at boot
You tin accomplish it inward multiple ways.
By editing rc.local file
You tin ready it at startup past times adding the higher upward commands (choose pick 1 or 2) at the destination of /etc/rc.local file together with amongst exit 0 at the end.
Some would fence to use
update-rc.d <your script> defaults
Using GUI – Start-up Programs
Move IncreaseWifiTx file to /usr/bin.
mv IncreaseWifiTx /usr/bin/IncreaseWifiTx
Make it executable
chmod +x /usr/bin/IncreaseWifiTx
Now simply follow these steps:
- Click on “Applications” –> “System Tools” –> “Preferences” –> “Startup Applications”
- Click “Add”
- Add these details
- Name: Increase Wifi TX
- Command: /usr/bin/IncreaseWifiTx
- Comment: Make my Wifi run HOT
- Click Save
- Close.

Thanks for reading.
p.s. Thanks to Hitman for his instructions together with NopSled for pointing out the effect amongst BO. I’ve updated the guide amongst GY instead.
