One of the common problems encountered by early Galaxy S3 adopters back in 2012 was the device kept on scanning for available WiFi networks but couldn’t connect even if it could find one. Other users reported the device would go about the ordeal without even the success of finding an available network to connect to despite the fact the user is a foot away from a working router. This problem is also starting to build traction on Galaxy S4 as more and more owners going forward reporting this very same problem.
The good news is it’s neither a bug nor a serious hardware issue with the device. In fact it occurs only to owners who connect to the same network every day for quite some time already. The problem may be caused by corrupt connection data that forces the phone to scan for available networks despite the fact that the network it is trying to connect to was already saved in its memory.
Basically, there are two things you can do to fix this problem on both the Samsung Galaxy S3 and the new Galaxy S4. At least, 80 percent of the time this problem will be solved by ‘forgetting’ the network and letting the devices scan for it but if it doesn’t do the job, clearing the memory would do the trick.
