IPhone :: Choose A Network Won't Pull Up Any Networks?

When I go into Wi-Fi Networks under Settings, the Choose a Network doesn't show any networks - just a spinning circle every few seconds, but nothing comes up. My network used to show up here with a check next to it. The bars at the top of the phone show I am connected to Wi-Fi (I am on my network ok), but in Settings it shows Wi-Fi is Not Connected. I have Reset my phone, but it didn't fix it. I am reluctant to Reset Network setting because I won't be able to choose a network if none are showing up.

Info:
iPhone 4S, iOS 5.1
