My iphone 4s is not connecting to Wi-Fi?

It kept showing me up at the top 3G and then the Wi-Fi bars. I didn't know why it was doing this so I tried resetting network settings but I actually regret that. It's not "greyed out'' or anything but when I try to connect to our network and I type in the password, it shows the Wi-Fi bars on top but then it says I failed to join my home network. I'm using ios 7 right now and know I should update to ios 8 but i only have 5GB of space.
What's going on?

In the settings menu disable 3G or mobile internet. This will remove the 3G data use.

then, in the network section in the settings, you should find the Wi-Fi settings, find your router and open it, put in the password as it is written, if there are CAPITALS, you need to put in capital letters, because Wi-Fi network passwords are case sensitive (upper and lower case letters matter).

  • Wi-Fi on iPhone 4S not connecting? I have the iPhone 4S and I've had it for about 11 months. I don't keep up with downloading software and things, but I decided today would be a good day to get some new music and maybe get iOS 6.0.1. However, I tried connecting to my houses Wi-Fi and it would have the little turning circle and say it was connected, but it would still say it was using 3G. I tried restarting my phone, but nothing is working.

And I soon realized that their was Wi-Fi in my house titled "dlink" I've seen this public Wi-Fi before at an old house of mine. Well anyways. It's been working fine for a a couple weeks now. But today around 12 I came home and my phone wouldn't connect to the Wi-Fi. It just does that little loading sign, and it doesn't stop. It just keeps going, can anyone help?
