My Wi-Fi isn't working on my iPhone?

So for about 3 days now my Wi-Fi hasn't been working on my iPhone, we have our own Wi-Fi and it worked perfectly fine but lately every time I go to settings to turn on my Wi-Fi it won't let me at all it's just grey it won't even let me slide it on, and I've turned my phone on and off but it's still the same and everyone else's phone gets the Wi-Fi expect mine?

If the Wi-Fi is secured try to delete it from your phone and after that try to reach it again.

My iPhone does the same thing. Your phone is likely doing this because the Wi-Fi antennae in it is broken. I don't know of they can fix that problem though. I dropped my phone in water and the Wi-Fi broke. So I had it fixed, took it to apple, and they confirmed that they could not fix it for me.

  • Why isn't Wi-Fi working on my iPhone? 3G works (that's what I'm using now) but Safari or anything else that uses internet won't load when I use Wi-Fi. Why won't it work?
  • Why isn't the 3g on my iPhone working? It just has a E sign, and nothing will work. Instagram, Twitter, Tumblr, Youtube, etc. I tried restarting it, it still won't work._.
  • Why isn't my iPhone charger working? I have an iPhone and it was working fine but yesterday when I plugged it into my phone it would not charge. So I tried my brother's iPhone charger and it worked. I looked it up online and I think there's a problem with my USB cable and not the wall charger itself. What do I do?
  • Left side of my iphone 4 screen isn't working? Nothing on the left side can be pressed! I did a hard reset (pressing the home and off button) but it didn't work. Then i completely reset it, but there's no difference. I don't have an apple store where i live, how can i fix my phone? Btw, i can still do the *slide to unlock* which is odd, considering that that requires use of the screen's left side
