Android WiFi Power Management Apps

[axis.meister]

Hello friends,

It seems that the Transmission power of my Canvas HD(running SamHD v3.2) WiFi chipset is low, because sometimes I cannot connect to my Wifi router (Asus RT-N13U with DD-WRT) from certain places in my house, while I can connect from the same place using my tablet or my laptop or my brother's O2X. So I was using this WiFi TX power management utility while I was using the stock ROM, and it seemed to work(sometimes).

Now I am using the SamHD ROM and it does not have iwconfig that is used by this utility. I know I could find a workaround by adb'ing iwconfig into this ROM or something else, but before I do that I wanted to know if any of you use any WiFi Power Management app and if they actually work for you?

Any suggestions for alternate tools which contain the iwconfig/iwmulticall utils are also welcome.

Looking at it from the router side, since you're on dd-wrt, did you try to increase the tx power on the router ?

There is a limit here, you can increase little more before the signal starts to distort. The advantage is you do it on one end instead of having to use this app on your mobile devices, if you push up the tx power then your battery on the canvas will take a hit.

The battery life on my phone is quite good, so I am not worried about that. Increasing the tx power on the router is one solution, but that would be my last option since the router is not the issue. All other devices work fine.

if you increase power on the router (How hard is it to do ?) its much simpler than having to install anything on the device

if that does not work then your custom solution on the phone would be next.

It is very simple to change the power on the router, but then the router is not the issue here, it is the low tx power of the phone chipset that is the issue. I have already ascertained that since all other devices work fine on the same tx power rating of the router.

Anyways, I fixed it. Found the iwconfig binary on the stock ROM, and pushed it to the device via adb(since /system/xbin is RO and you cannot directly copy to it using file manager). It is easy, just in case anyone wants to do it, you need adb on your PC

then use

adb push iwconfig /system/xbin/iwconfig
adb shell chmod 755 /system/xbin/iwconfig


*DONE*

now wifi tx power finds iwconfig.
