title: Galaxy S3: Wi-Fi issues / url: wi-fi


Wi-Fi connection optional

What is it with mobile devices and Wi-Fi connection issues? Several users on internet forums have complained that they're unable to connect to Wi-Fi, either at home or work, on their S3 handsets.

And when they do, the connection only lasts for a matter of minutes.

A user on the XDA-Developers forum claims the problem is rooted within the handset itself and that the connectivity issues aren't the result of a faulty network.

But if I try and USE the net or data connection, it's a dog's dinner... If I run a Mobile Speed-test, I get a terrible ping, an average download speed of 0.02 Mbps, and then it times out three quarters through with a connection error.

"It has done this since I got it Wednesday. However, I can confirm it is the PHONE, not my home wi-fi, as my Router is very new and mega-top end, and my three SGS2's are working absolutely fine on it. Moreover, if I pull the Notification Tray down on my SGS3, then disable Wi-fi, then pull back down, then re-enable, and then run the speed test again, I get great pings, 22Mbps Downlaod, and 5Mbs uplaod speed (my Home Internet is 100Mb).

"So clearly pointing to an issue with the phone. It does this on both 2.4GHz, and 5Ghz, as my router is full dual channel, independent. Looks like either a faulted phone (hope not), or a fault in current Kernel of the software, which would be better, if a fix was forthcoming.

"This bit is really bothering me though - a brand new device, and it's the only device in my home that has issues with connectivity and web."

His concerns have been mimicked by other users who claim to have encountered the same problem.

While Samsung hasn't released an official fix yet - chances are it will roll it out in the form of a software update - a user on the AndroidForums claims the following fix will solve the issue.

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."

T3 hasn't tried the fix, however, we're interested to hear whether it works - so far, feedback has been mixed. If you'd like to comment on the fix, ensure you hit us up on T3's official Twitter and Facebook pages.
