My Iphone won't connect to my Wi-Fi

Ever since yesterday my IPhone 4 AND IPad will NOT connect to my home Wi-Fi. My IPad connects perfectly to my schools Wi-Fi but mine. Everyone can connect to my Wi-Fi but me since I'm the only one with apple items. I tried turning off and on my phone, forgetting the network, turning on and off my Wi-Fi to fix the problem. But all it says is 'Unable to join network' it's getting me very mad because I have homework on my IPad I have to do which I can only access through the IPad.

It's your network. Since it is happening on both at the same time.

You can try Settings-General-Reset-Reset Network Settings and then try and re-join it again but I doubt that will work. Another thing I recommend is unplugging your router from power and plugging it back in.

  • Why won't My sprint iPhone 4 won't connect to 3G? Before you say call them I already have ok. Today I had an upgrade but my aunt used it for her phone since I'm on her plan. It went good but then won't connect to 3G after that we called and they said something went wrong but nothing did so I'm wondering is there anything i could possibly do to fix it or should I call the place that did it? Or should I just call sprint or apple? Please help I have to use my phone a lot in places that don't have Wi-Fi.
  • Why won't my brand new iPhone 5C won't connect to my home Wi-Fi? I just recently bought an iPhone 5C for my mom, along with an HTC One. The 4G LTE seems to work fine on both of them, but my iPhone can't seem to connect to my home internet (the HTC connected perfectly fine). I'm 100% sure I'm inputting the correct password, and it always comes up with the same error: "Unable to join the network '[my Wi-Fi name]'" I've tried turning the phone and router off and on, but it doesn't seem to be doing the trick…
  • My Wi-Fi won't connect on my laptop but will connect to my other devices (an iPhone and iPad)? I have a MacBook Air. Sometimes it does connect but other times it just won't. It takes ages connecting and then in the end comes up with the exclamation mark or is just blank. Is this a problem with my laptop? I've tried researching the problem but have found nothing.
