    Welcome to Android Central! When you turn on wi-fi and look at the Settings>Wi-fi menu, do you see the list of all available networks and their signal strength, or does the list stay blank?

    The fact that your battery level drops while charging suggests that (a) whatever you're doing while charging is using more battery than the charging rate, and/or (b) your battery is old and failing. Try a new or different battery.

    Are these open public wi-fi networks that are known to be connected to the web?

    I don't think so if the public wifi connected to the web. Well even in my house if I'm not near in my router I can't connect it say "saved and secured " but it's not connecting .

    Do you have a case on? Some poorly designed cases can actually interfere with reception.

    See if the problem persists in Safe Mode: https://support.t-mobile.com/docs/DOC-32821. If it does, then it is more likely to be a hardware problem. That phone is pretty old, so I wouldn't be surprised if it was failing.

    Here's the text from that link:

    Turn on and use safe mode

    Safe mode allows you to turn on the device with third-party apps disabled. Then you can easily uninstall apps that may be causing a conflict or software problem.

    1. Turn the device off.
    2. Press and hold the Power key.
    3. When 'Samsung Galaxy S III' appears on the screen, release the Power key Immediately after releasing the Power key, press and hold the Volume down key.
    4. Continue to hold the Volume down key until the device finishes restarting.
    5. 'Safe mode' will display in the bottom left corner of the screen. Release the Volume down key when you see 'Safe Mode.'
    6. Uninstall apps that are causing a problem.

    Turn off safe mode

    1. Press and hold the Power key.
    2. Tap Restart.
    3. Tap OK.

    In that case, it's probably a hardware issue. You could try a factory reset, but I doubt that'll do anything. It's probably time to get a new phone. Sorry!

    Newer version of Android? That phone won't go beyond 4.3 officially.

    You'd have to find a custom ROM designed for that phone based on a higher Android version. Installing a custom ROM requires rooting the phone. And it probably wouldn't solve your problem, since it sounds like a hardware issue.

    At a (experienced) guess, the antenna connector came loose, so the only "antenna" left is a little piece of copper - or the antenna itself went bad from shock (dropping the phone or knocking it against something). The "even in my house if I'm not near in my router" part is almost a label that says "bad antenna or bad wifi transceiver". If it's the transceiver, it probably doesn't pay to fix, because you'd have to have the motherboard replaced, and you can buy a gently used S7 for less than that would cost. (Most of the cost is the labor - you can get the motherboard itself for US$20.)
