I'm having issues with Maps and Pandora radio and Wifi

Hey all,

Was wondering if someone can please help me out! First I'm having issues with the Wifi, I already have a network saved on my phone which is my home network and before it was running fine but some reason it's not wanting to connect and I checked the modem and it's fine, or else I wouldn't be using my computer right now with internet LOL

I have no idea what is going on with the wifi on my phone, it's not wanting to connect and the password is correct but I don't know what the deal is

Second issue is the maps not loading like it's supposed to. I was on the phone earlier with a friend of mine and I was using the maps thing as I was talking to her on speaker but, now I can't get the darn thing to load and Pandora is not wanting to load either. I tried to unistall it and re-install it but it's not working!

Can someone please help me! I don't want to have to reset my phone and lose everything
