My iPhone 5 will no longer connect to the Wi-Fi at my house?

A few days ago my iPhone 5 started not being connected to the Wi-Fi I have at home. There's no Wi-Fi to even choose from! You can just select "other" and nothing works… It can't find any Wi-Fi at my house. When I go to school it connects to that Wi-Fi, and when I go to my friends houses it connects automatically also. And, my laptop automatically connects to the Wi-Fi at my house! So I'm really confused. How do I fix this? Plus, I can't restart my phone cause my lock button is broken. (I obviously got a bad phone which I'll probably take back) but for now please help?

First try updating. It may be because you're on an old firmware with a Wi-Fi based issue. If that doesn't work, go to settings>general>reset>reset network settings. And then try reconnecting.

If that doesn't work I would just take it to the nearest apple store. Unless your screen is cracked you're still under warranty and theyll fix or replace it due to the faulty sleep/wake button anyway.
