Hello to the Android World, I am on Samsung Galaxy S3 running on android 4.3 . My problem is that the S3 detects the WIFI, scans it from every part of the house perfectly fine. But it only gets connected when I am in the same room as the router. Whenever I move away from the room containing router, the device shows the internet as only saved and secured and does not get connected. I mean it only happens with my device, other all device works perfectly fine from every part of the home. Also this problem does not only happen with my home wifi it happens with every wifi. Things I have already tried doing. 1) Factory reset the S3. 2) Use custom frimwares. 3) Use apps such as wifi analyzer, wifi fix. Please help me get past this problem.
