RE Manager to enter the system \ wifi directory mounted read-write

To open nvram.txt find pa0maxpwr = 66 (the official default 66) the value changed to any value within 66 to 100, the higher the value, the greater the power to modify completed remember to save. The open nvram_MSM8255_C8860.txt to find pa0maxpwr = 76 (the official default 76) the value changed to any value within 76 to 100, the higher the value, the greater the power to modify completed remember to save.

Improve the value to change the big WIFI coverage to improve the network speed, but power consumption when using WIFI is equally rapid increase

So obviously lowering the number should conserve power? I was attempting this yesterday with a market app, not sure it worked though

[Guest FrankieADZ]

be interesting to see if anyone gets this to work

[Guest Davidoff59]

I followed this guide although I used a different iwconfig.

There is then a market app which can set the power from 4-32 dbm. It didn't appear to work for me and while I have iwconfig, adb can't see it

Changed mine to 10 and 26 with no slowdowns or ill affects next to the router and I still have full coverage. If coverage drops when upstairs, I will report back.

I cannot get mount/sdcard to work, no such file or directory ? is it named different on g300 ? like sdcard2 ?

edit: got it, no need to add mount in the command so, cd /sdcard

Strange, when I run iwconfig I see no values ?

That's what I got jiko. I think the WiFi chip has to support it bit it appears that its already there so I didn't have to add it as I did previously.

As an update, there is no drop in signal with my set values from above. Hard to know if it actually works as my setting is considerably lower than stock and I am 3 stories up with good signal.
