Internet Connection not working on iPhone?

Recently I got the iPhone 5, I put my internet connection on it but I accidently put the wrong pass-code and now it just keeps loading and loading and doesn't stop, I tried my cousins connection and it works fine but every time I click on mine it keeps loading and doesn't stop.

Go to the Wi-Fi portion of the iphone, when you see the wireless network name, hit the blue arrow on the right of the network name. On the next screen click the button that says forget this network. Then try to reconnect with the right password. This will work

  • Why is my Wi-Fi connection not working right? I have been experiencing problems with my internet. About a week or two ago my internet started acting funny and then started being normal for a week, then yesterday started acting weird again. The problem is it won't connect my laptop but all the other laptops can connect, iPods and iPhones have connection but it flashes on and off, same with the 3ds, and it kicks you off xbox live. My service is optimum and the tv and phone works just not the internet Wi-Fi.
  • Why internet connection not working? Ok so if my Wi-Fi is working on my laptop and my xbox live, why isn't it working on my iphone 5. Well it works, but internet is slow. But when I restart my iphone, it works for only like 5 minutes then its slow again. This mostly happens in my facebook and instagram. Now, there's no network connection mentioned in my instagram when I was logging in. Username and password is correct but there's no connection. I don't understand.
  • Why does my iPhone still charge for Internet even when I'm not using Internet? So, I recently got a pay monthly plan with my new iPhone 4s. When i'm out and about I'm usually updating my twitter and Facebook account. But, when I'm put my phone down, 3G still says I'm using it and charging me. So do I have to turn it off when i'm finished? Or is there a much easier way?
  • My Iphone is not letting me access the internet or internet based apps? I have an Iphone 5. Never had any issues but now it won't connect to the internet or any apps. It does the same thing it does when I have no service (just has that little circle symbol that means it's trying to get through). Orginally, I thought it must be a universal problem but everyone else has service and they are in the same location as me. Also I always use my phone here with no problems. I have tried turning it off and on again but nothing.
