Increase TX Power Signal Strength of WiFi


This is a small guide on How to increase TX Power Signal Strength of WiFi

This guide contains 3 different methods to increase your TX Power or Signal Strength of your Wifi Wireless card. It also includes 2 ways to make those changes kick in at boot time so that you can enjoy the extra power everytime you boot into your Linux distro.

The default TX-Power of wireless is set to 20 dBm but you can increase it with a little trick to 30 dBm but let me warn you first that It might be illegal in your country, so use it at your own risk. Moreover Some models will not support these settings or wireless chip may state that it “can” transmit with higher power, but the device’s manufacturer probably did not place the appropriate heat sink in order to accomplish this. Readers MUST use this guide knowing what is allowed or not allowed in their country. Author is not responsible for any action taken by a reader.
