Wi-Fi networks my showing up anymore? IPhone 4s?

I've had my phone for over a year and never gave me this problem before. I have not changed anything or updated recently but earlier today it disconnected and has not shown any networks on my phone. The Wi-Fi works fine, since it connects to everything else (xbox, laptop, etc).
The Wi-Fi is NOT greyed out. It just doesn't ever show any networks.

I have tried turning on and off, airplane mode, moving around near router, resetting settings, resetting network settings, manually connecting, and many other things.

When it stopped working I was just browsing through safari.

Have you tried unplugging the power from the router/modem for about 2 mins and plugging it back in?
While the router is off, turn the phone off and power it back on after the router/modem has finished booting?

  • Will any Ireland Mobile Networks support L. T. E (4G) or iPhone 5? The question pretty much says it all. Does anyone know if any Irish networks (I know Vodafone and O2 are not) supporting LTE:4G data? Specifically for the iPhone 5. Leave the fanboy troll comments at the door, a simple yes/no specifics are what I'm after.
  • Why can't my iphone 3g find any wi-fi networks? My iphone 3g is not picking up any wi-fi networks but it's never done this before, i was wandering what happened, does anyone know?
  • My iphone 4s won't recognize any Wi-Fi networks? Recently my iphone 4s stopped recognizing any Wi-Fi networks, i did some research and seems that a lot of people have this problem howeverthe new iOS 6.0.2 update is only availible for iphone 5 and ipad mini. I have pretty much tried everything that i can possibly do to try and fix the issue but nothing works. Does anyone else have this problem? And do you know how i can fix this issue? And does this mean my Iphone 4s is broken? Or it can't be fixed?
  • IPhone 4 has no Wi-Fi networks? So, whenever I open up my Wi-Fi thing it says there aren't any networks to connect to when I clearly have Wi-Fi in my house. I've tried entering the network and password manually, still doesn't work. I reset my settings, still doesn't work. I turned off my phone, still doesn't work. It's only my Wi-Fi that doesn't work, too. It works everywhere but here.So, WTF!
