Can I block out a device from connecting to my Wi-Fi?

My dad's iPhone keeps shutting my internet down when he leaves/enters the house with it. It really screws me over when playing an online game. Is there a way that I can block his device out of our Wi-Fi? He is a very old fashioned person and doesn't know that the iPhone can do more than call/text so he won't notice at all if block him out.

Added (1). I play online games, he does not.

Can you repair a broken iPhone screen without replacing it?

I have an iPhone 4, and it has a very small crack in it. It isn't really impacting the phone at all, but if my parents see it i'll be in a lot of trouble. Since it's not a crack serious enough to need to completely replace the screen, s it possible to fix the crack? I know you can fix scratches in CD's with a special gel, is there anything like that for glass or touch screens?

Added (1). Also, if it isn't possible to fix it instead of replaceing it, could you explain why?

Does apple have a warranty for stolen iphones?

I was at my friends house last night & she had a small party. My iphone 4 was plugged into an ihome playing music and i left the room for about an hour and a half but when i came back, most of the people there were gone along with my phone. I've tried calling it, texting it, and using the Find my iPhone thing, but whoever stole it turned it off (there's no way its out of battery, last time i saw it, it was on 100%) so basically my questions are, is there a way you can turn on an iphone without physically being near the phone? Is there another way to track it? And if nothing else works, does apple's warranty cover stolen iphones?

Is it free to send picture messaging on Iphone?

I have a 4s iphone on 3 and I'm on contract but sometimes it adds additional charges on and now this months is £2.18. The breakdown of it shows it's from picture messaging but I thought this would surely be free and why is it so expensive I only sent like 2/3. When I'm on Wi-Fi it sends as a text message sometimes and so charges, it only doesn't when sending a pic to an ipod! I dunno I'm not good this technology help! Xx

I need your opinion on this?

I want to get an iPhone 5s in Gold, but it is sold out and Verizon will backorder it by 11/11. Should I wait that long (about 5 weeks)? My phone broke down today but I don't want to waste money on a phone I don't want, but I also can't go 5 weeks without communication. What is your opinion?
