Iphone 5 won't connect to home Wi-Fi anymore?

Up until about two days ago I could sit in bed and use the Wi-Fi at home normally with no problems. Now whenever I go to my room it won't connect! However if I use a laptop that connects just fine. The connection is practically nonexistent unless i'm standing in the same room as the router or at least really close to that room. It's never done this before. I used to have excellent connection throughout the bottom level of our house and my room upstairs. Why is it doing this? How do I fix it? I've already tried rebooting the router and forgetting the network on my phone and then rejoining it. I've also tried turning my phone on and off so what do I do?
