How to Pick Up a Better Wi-Fi Signal on Your Samsung Galaxy S3

Having trouble getting a strong Wi-Fi signal on your Samsung Galaxy S3? Does the signal drop out on you when changing rooms? Frustrating, isn't it?

GS3 SoftModder forum member Taral had the same problem, and asked about ways to increase the Wi-Fi range on his GS3. While there are numerous things you could do to get a better signal (new router, range extender, etc.), one simple trick is to turn off WiFi Power Saving mode.

Best thing about this hack? It's super easy and root is not required! You will need a Touchwiz based rom, this will not work with AOSP (CM, AOKP, ParanoidAndroid, etc.)

Step 1: Access Hidden Menu

Go to the Dialer and dial "*#0011#" (minus the quotation marks).

Update: Through the comments, it has come to my attention that the dialer code above may not work. Research shows that most carriers, aside from Sprint, have disabled easy access to this hidden menu following the Jelly Bean update.

If the code above does not work for your device, try the following:

• AT&T/Bell/Rogers: *#3197328640#
• T-Mobile and Verizon: *#22745927*, enable Hidden Menu, then use the code above, *#0011#

Thanks to forum members Barb, Dan, and Anthony for help figuring this out!

Step 2: Access the WiFi Section of the Hidden Menu

Once in the hidden menu, you'll see a fairly blank screen. From here, press the Menu button and select WiFi.

Step 3: Turn Off Power Save Mode

Now that you're in the proper menu, turn off the Power Save feature by pressing the "On" button. It'll change to "Off".

And that's it!

If your Wi-Fi was working fine before, you won't notice much of a change in your normal usage areas. But if you used to struggle with connecting or maintaining a signal, you should see results right away.

Keep in mind, this will not magically increase your range to absurd distances, nor will you be able to go through that lead wall of yours. And don't worry, just because you turned off "Power Save" does not mean your battery use is going through the roof. In fact, I haven't noticed any increase in battery use from this mod.
