If you want to disable it again just follow the instructions below.

Edit: Forgot to mention this is a reminder in case your wi-fi gets "stuck" (you see you are connected to your network yet are getting no data)

1. Go to your phone dialer
2. Dial *#0011#
3. When you see the "ServiceMode" screen, press the left menu button
4. Select "WiFi"
5. See that "Wifi Power Save Mode" button that is "ON" - well turn it "OFF"
6. Exit this menu, turn off your Wifi and turn it back on. If you already entered all your wifi credentials, forget your network info (remove it) and re-enter it again.

It's only for your WiFi having issues. There have been some instances people show as connected to WiFi but they are not able to access the Internet. You do this and you should be able to access again.

It may have been fixed in JB. Not sure though

Fyi I went to turn it back on and it apparently turns itself on again upon reboot.

Hello,
I was wondering how does Galaxy S3 Power Save Mode work?
When it tries to turn off the wifi? Is it the IEEE 802.11 PSM mode?

Thank you

Don't do that, unless you have to do it for some reason (that is unless your WiFi gets stuck). If you turn off the WiFi Power Save Mode, your battery will drain like crazy. I tried that after upgrading from jelly Bean 4.1.1 to Jelly Bean 4.1.2 and I ended up with a battery that was draining 3-4 times faster than usual.

Not really i did that it seem use less power.

If you turn on wifi power save mode your wifi internet connection speed will be very slow. Like in my case I have a 15 mbps internet plan but using the speedtest.net app on my phone the speed is only 1.5mbps. But after turning off the wifi power save mode I get a 15mbps connection.
My question is, is there a way to permanently turn off the wifi powersave mode? It's really annoying I always need to do the *#0011# sequence everyday!
I think it automatically turns on when you get a low battery or if you restart your phone.

That's odd. I just ran four tests, two with PSM off, then two with PSM on, and got essentially identical results using Speedtest. Did you run your tests with a low battery? Maybe the powersave mode kicks in when the battery reaches a certain level.

Unfortunately, I'm not aware of any way to change the setting permanently.
