My iPhone 5 will suddenly not Connect to my Wi-Fi?

Will connect to other Wi-Fi locations, but not my house. So obviously it's my network at home. I check for blocked devices, and it wasn't there, and then I even added the MAC address to the allowed devices.

No change.

What do?

Try to reset your router. If not working, there might be something wrong with the wireless receiver.

Does anyone ever open the phone to fix anything?

First reset your network setting which erase all saved Wi-Fi networks if not worked then RESET not restart your router hope it will resolve.

  • Suddenly can't connect to college dorm Wi-Fi? I have an Asus laptop running windows 7. My friends laptops and my iPhone and tablet can all connect to the Wi-Fi here but recently my laptop hasn't been able to identify the Internet. Before whenever this would happen I would restart my computer and I could connect. But not not even that works.
  • IPhone suddenly not working overseas? I'm in Germany for 9 days and I bought the international service plan and so far(been here for four days) it has worked perfectly but yesterday we flew into Munich and it worked fine until i got to my room where it said searching for the whole night. The Wi-Fi from the hotel was bad in my room and i have Wi-Fi now and it says I have bars but where it should say the carrier it says nothing. What do I do?
  • IPhone 6 Plus camera suddenly not working? My camera suddenly stopped working yesterday morning. My phone is brand new and has only been dropped twice but on my carpet, it has always been in a case though. It doesn't work on any apps either, the thing is it's only the front camera. The back camera and the flash are both working fine. I'm not selfie person but it still bothers me. What should I do? I've restored it and hard reset the phone. I don't know what else to do at this point.
