my iphone 4 disconnected from my wifi and will not reconnect what to do?

Hello Lalaladonna,

It sounds like you are not able to connect to Wi-Fi on your iPhone. I found a couple of resources that will help troubleshoot Wi-Fi issues on the iPhone:

Joining and troubleshooting Wi-Fi networks

Thank you for posting in the Apple Support Communities.

Best,

Thanks for the help, have tried all the above and nothing works, I believe it is a hardware issue and will send it back.
