DAE Have awful WiFi Problems (more info inside)

So I like to watch youtube and twitch on my iPhone 5 and iPad mini, but I really can't without manually reconnecting the wifi every couple of minutes. Neither are jailbroken, the iPhone is on iOS7 (it had the same issues back on 6.1.3), and the iPad is on 6.1.3 too. I also remember having these issues when watching netflix on my phone when I had it (Netflix was terribly inconsistent on my apple TV too but I think that is unrelated). I know this is specific to these devices because all these services are fine on my macbook (wireless) and my PC (ethernet) and this is my connection; ping:32, down:50.89mbps, up:14.62mbps. So does anybody know what could be the cause of this issue and how I could fix it.

Thanks.
