IPhone 4 won't connect to home Wi-Fi?

It was just connected to the school Wi-Fi, I turned it off when I left then turned it on when I got home. It says its connecting but never does. I know the password is correct, also. I have restarted my phone twice, and reset the network settings, too. I have iOS 7. The Wi-Fi has been kid of weird the past couple of days but its working on my iPod but not my iPhone so I don't know what to do?

Try to reset it

  • Why won't my iphone connect to my home Wi-Fi? I have an iphone 4 and whenever i try to connect it to my home Wi-Fi it says 'unable to join network'. On my parents' iphone the Wi-Fi works fine. I also have the same problem with my laptop. I can go to another Wi-Fi hotspot and it will work fine but with my laptop and my phone it never works. I've tried restarting my phone and the router already. How can i fix this?
  • Why won't my iPhone connect to my home network? It's connected before today but my mom had people come in and fix it because when she would connect to it, the router messes up and no one was able to use the internet. Now I can use my desktop at the same time she uses her wireless connected laptop. But my iPhone won't join the network and neither will my other laptop.
  • Why won't my iPhone 4s connect to my home Wi-Fi? - 1 I didn't get the new ios update or whatever, but recently it hasn't been able to connect to my homes Wi-Fi. I've never had this problem before and my houses Wi-Fi doesn't have a password. It doesn't even seem to acknowledge that the Wi-Fi is there, and my iPad doesn't have this problem.
