How To Increase WIFI Signal Strength

How To Increase WIFI Signal Strength

Requirements:

1. Wireless card (some wireless card cannot configure tx-power)

2. Wavemon (apt-get install wavemon)

Concept:

The default Tx-Power of wireless is set to 20 dBm, usually used by 802.11b/g Wireless LAN.

We will be able to set the Tx-power default setting from 20 dBm to 30 dBm.

Steps To Follow:

Step 1:

Open up our terminal and type ifconfig and make is sure your wireless network already detected and up.

Step 2:

Now let's check our wireless card default tx-power by running this command.

Step 3:

When we check the default signal quality through wavemon, it will be like:

Step 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 wlan up

Step 5:

Now we can check again our wireless card status by running: iwconfig wlan0

Step 6:

If the tx-power has already changed, let's check our wavemon, and see the difference.

Step 7:

We can set up our wireless card into specific channel by running: iwconfig wlan channel 8 or we xan also directly change the tx-power using this command:

iwconfig wlan0 txpower 30

WE DID IT!
