[SMALL FIX] Increase Wifi TX power ("signal strenght")

[zdzihu]

Hi, I noticed that our wifi driver can be controlled via iwconfig to increase TX power. It's not too impressive change (from default 14dbm to max 15dbm), but still it's a ~25% transmission power increase considering miliwatts (25mW->32mW)

Please remember it will slightly improve your wifi connection, but also increase the power consumption!

HOWTO:
Use the file everytime you switch on the wifi (or create a relevant script):

iwconfig wlan0 txpower 15

Download: iwconfig


Cheers,
z

To use this script, execute it from the terminal. Copy it to anywhere into your memory card. Open up Terminal Emulator, cd to /sdcard/location/of/the/file/ (e.g. /sdcard/download) and enter the command from the first post.

Here's a simple script that might work. I haven't tested it yet:

#!/system/bin/sh

/system/bin/iwconfig wlan0 txpower 15

Save as whateveryouwanttonameit.sh in anywhere you want (a folder for scripts in sdcard is recommended). You need to copy the 'iwconfig' file into /system/bin for this to work and run this script from Script Manager or Gscript or anything that can run the script (including Terminal Emulator). If I'm not mistaken, you can create a simple widget for scripts using Script Manager.

Hope it works. Thanks zdzihu for this great find.

The alternative suggested to Zdzihu's does not work

Nobody has found the widget suggested in this link as an alternative to work! English translation of the Russian thread. Its battery draining effect however persists. Take care!

@rapatu2010
well man, I'm using it quite OK, and don't experience any drains at all. It works great for me as well as for many other users. If you can't install it, then don't complain to app.

You need to be in root mode first. If you're on Terminal Emulator, you need to execute the command su first to be in root mode and you're good to go.
