My iphone will not connect to Itunes? - 1

I have a Iphone 4s, windows 7 Hp labtop.
I have reinstalled itunes many times and it will not connect. I put the phone in DFU mode and still will not connect to itunes. What it does is once it connects to the computer it will charge, open autoplay, and import pics. Its doen't open itunes once connected like it used to and when I open itunes and connect it, it still won't show up.
The only device on my itunes is my iphone ONLY, so that parts not the problem with different devices. Also when I connect my iphone goes to the do you trust this computer thing, I "Trust" and thats when it opens autoplay and imports the pics, but still will not show up on itunes.
I've also seen when I try to do personal hotspot to this computer through USB it just keeps going to the do you trust.

So I have no idea what's going on and I need help real quick.

  • My iphone will not connect to my home Wi-Fi. It can connect to any other network with no problems All my other devices at home connect with no problem, but once i updated my phone it won't connect here. I've reset the router, my network settings, forgot this network, even wiped out my phone and it still won't work. I changed the dns several times. Sometimes that works for a little while, but then eventually stops. What the hell?
