iPhone 4S Dropping Wi-Fi

Hi Everyone,

Recently, I have noticed that my Wi-Fi drops when I'm at home. This is particularly irksome since I don't always notice and I'm using my phone for Internet access (and will now be charged accordingly). I've rebooted my router and that helped a couple of times, turned off my phone, wiped out my Wi-Fi on my phone and redid that, too. I'm out of ideas and I'm becoming increasingly frustrated, as this seems to be a new thing (maybe within the last few weeks).

Any help/ideas will be greatly appreciated.
