Two days ago my iphone was working fine but today it has stopped connecting to my home wi-fi. I am entering the password perfectly but it says "can't connect to network nirvana". I do not have an internet connection or data plan with my carrier. Therefore, I am pretty much dependent on my home wifi for my iphone's net needs.
You get up in the morning and check your emails on your iphone. That is a good start of the day. But my days were no longer going to be good. It took me two days to figure out the solution. Keep reading for the solution.
You have many options and all of them will succeed. First and unliked one is to connect your phone to iTunes and upgrade it to a new firmware. This will work but if your iPhone is jailbroken and you upgrade to 3.1.3 you can no more jailbreak it. So forget this option.
The other my recommended solution to this problem is to go to Iphone->Settings->General->Reset->Reset All settings. This should work for you. Sometimes resetting the network only settings work too. But if that doesn't work for you try resetting all settings. Once your iphone reboots you can connect to your home phone normally.
If even this doesn't work then you need to check if your iPhone is under warranty or not. If it is under warranty make an appointment with Genius Bar. They will replace your phone with a new iPhone.
