About a month ago I purchased the Samsung Captivate, and the wifi connection worked great. All of a sudden when I try to connect to a wifi network, I get an "unable to scan networks" error message. After doing some research online, it seems that doing a factory data reset seems like the only way to go about fixing this. So what I want to know it, is that the only way to fix it? If I do a factory data reset will I lose everything on my phone (contacts, pictures, apps that I've downloads, etc.)?
