Nice find! When I started, the utility reported that the TX-power was 1496dBm. When I told it to set it to 4dBm, it lowered it to 398dBm, so it does seem to be working (basically, you divide the number that the utility is reporting by 100).

It seems that the TF700 defaults to 14dBm and I just lowered it to 4dBm.

Now, whether or not it's *really* doing anything, I'm not sure. I'll have to do some further testing. But, this does look promising!

Thanks for sharing this. I'll report back after I do some further testing.

What problems are you having?

EDIT: FYI, it seems that 14dBm is the max and 1dBm is the min for the TF700. I have mine set to 1dBm right now. Will try to determine if it actually makes a difference next... :)

I finally managed to beat mine into submission, and shows reduced values now. Thanks for confirmation on that. Article showed values much lower than my tab reported. I'm also running at 1

Update: applied this to my phone as well. Added bonus, it drops power while hot spotting, so should use less power. If your tethered, your seldom more than a few feet away. Full power is a waste.

Read of an app called Wi-Fi tf power that supposedly switches power. I can't get it to work. All choices revert you back to default. (well, it does me) and I have to force stop it, reset permissions, and decrease it through term emulator.

Please keep me posted on your findings, and I'll do the same.

Oh, by the way, I'm running CleanRom inheritance 3.0.4 with these mods I'm trying
GREAT FREAKIN JOB! I love it

Running CleanROM Inheritance here too, of course - is there any other ROM for the TF700?!?! :)

Unfortunately, I can't say that I've noticed any difference, regardless of what I set this setting to on either my TF700 or my Nexus 7. The Nexus 7 also defaults to 14dBm and when I set either to 1dBm, I don't see any difference on my wireless router - the router runs DD-WRT, so I can see the actual signal strength coming from each device, which should get much lower when going from 14dBm to 1dBm.

I also have an Android phone, but haven't messed with it yet - I've gotten so spoiled by the TF700 keyboard dock and the larger screen size of the Nexus 7, that I try not to do much typing on the phone anymore! :) In fact, it's not even unlocked (it's a HTC 3D and requires some hardware modification to unlock, I think - never really looked into in that much to be honest).
