My Iphone 4 won't connect to my home Wi-Fi? - 1

When I go to settings and click Wi-Fi I see my Wi-Fi and when I click it, it would say, "Unable to join the network." I reset-ted the Wi-Fi settings, turning the Wi-Fi on and of also with the ask to join networks, I updated my phone by connecting it on my pc and turning my phone on and off. Please! Help me. I don't know how to go about this matter.

Since I'm not an iPhone 4 user, I can't confirm whether this answer is correct or not.

Change your router's security settings. The way your router is secured could not be compatible with your iPhone 4, therefore changing from something like WPA2-PSK to Static WEP.

Check your router's settings page (usually 192.168.1.254 should be typed in the address bar), and change the security type settings.

  • 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.
