What is wrong with the Wi-Fi for the 4S?

I got my phone just last last Christmas (December 25, 2012). Everything was great, my first Iphone (since I came from Samsung). Though it came with a problem (showing wrong battery percent) later on, the problem was gone!

Now that it is a year older the Wi-Fi all of a sudden had a problem. I can turn on my Wi-Fi, but it can't read the Wi-Fi! Sometimes though it picks up, but most of the time no Wi-Fi. I looked it up why it is like this, and other users of the 4S complain of there Wi-Fi because of the recent iOS7 update. But my Iphone was perfectly fine even after the update, until all of a sudden it doesn't work anymore.

Apart from that problem sometimes the phone would hang and I have to either lock and unlock or simply wait for the screen to restart. Is this a possible reason for losing Wi-Fi? My phone also has no protection (which is obviously not good), and I remember dropping it several times in the past. Could the problem come from these times? Or it has to do with its software?

You can try for Hard Reset >> Push Home Button Hold, And Push Power for Off.

Last time i use this method, And can connect to Wi-Fi normally

If you don't understand, You can type on search engine " Hard reset for iphone"

  • Wrong text prank, guy with gauges? Hi! I can't seem to find a text prank online. I've seen it before, and it seems pretty common. I think it's an iPhone text, and the original texting is in his young teens, with not too good of grammar. At the end, the "troll" guy sends a picture of himself, derping with plugs/gauges. Any help would be appreciative!
  • What's wrong with my eye? (picture)? It's a little hard to see, maybe, because my iPhone couldn't seem to get a good picture. It's like 3/4 blue/gray, and 1/4 hazel-brownish looking? What is it? And how rare is it? I've only seen animals with it, no people. I know people have it but I've never met a person with different colors in their eyes at the same time.
