My Wi-Fi stopped working on my iPhone 4S randomly?

I figured it's a hardware issue because it randomly comes on and off and no other devices on the network have the same issue. I decided I need to buy a new Wi-Fi antenna and a small screwdriver kit.

I'm just wondering, is this all I need or do I need a new "Wi-Fi bracket grounding" in link 3 as well?

My iPhone 5c won't let me slide it so it will unlock and i tried turning it off but i couldn't slide it so it would go off and i can't press cancel but i don't think the touch is broken cause i can slide those things at the bottom that can allow me to turn brightness up or down but then it won't let me actually touch anything.

So I click my dropbox icon and go to Camera Uploads folder and then it says "folder is empty" where the heck are my PHOTOS?
