Iphone 4s won't find Wi-Fi anymore?

I bought an Iphone 4s a year ago and as soon as i got it it connected to my home Wi-Fi and i used it and it worked just fine until last week i noticed that i wasn't on my Wi-Fi anymore and i looked and i can't find it on my phone at all i tried typing it in and it didn't work i reset network setting twice and didn't work i turned my phone off and Wi-Fi off and didn't work i reset my router and that didn't work but laptops and friends iphone 4s can still get on it.what's wrong with mine? And id prefer not to reset my whole phone.

Mine did this as well yesterday. I have yet to find out either.

Could be a hardware problem with your network adapter. Back your device up and make an appointment at your nearest apple store/genius bar, bearing in mind they are likely gonna wipe your device anyways.

Maybe cellular data is on

  • Why won't my iphone place calls anymore? This didn't happen until I upgraded to ios 6 last night and since then I can't place a call. I will select a person to call and it starts but it never connects then just says call ended. I have an iphone 4, that i got a few months ago. I can still text, listen to music, surf the web, basically everything else I have turned it on and off, and also done a hard reset, neither worked
  • Why won't my iPhone make certain sounds anymore? For some reason my iPhone is not making sounds for certain apps such as camera, or for standby mode. I checked the settings, and both "lock sounds" and "keyboard clicks" are on, yet I don't hear either of these. I know the speaker works, because it plays music and I can use speaker phone. Anyone have any clue what the problem could be? I also tried resetting the iPhone, didn't work.
  • Why won't my iPhone let me download anything anymore? I have the iPhone 4s, and ever since I updated my software to the iOS 6.0, I can no longer download anything to my phone. No apps, no songs, movies, I can't download any of it. For example, when I try to download an app, I tap the price then it says, BUY APP in green. Then I tap BUY APP, and it says that it is installing for a couple seconds, and goes back to the price.
  • Why won't my iPhone 5 send iMessages anymore? It's an iPhone 5 I got in February and it won't send iMessages anymore and yes I'm sure I'm sending the messages to an iPhone and my cellular data is on.
