iPhone 3Gs can't find network
I have an iPhone 3Gs that is running iOS 6.0 (10A403). This morning my phone can't find our home WIFI network. The iPad and my MacBook are both still using the network, but it doesn't show up at all on my iPhone. As far as I remember, it was working last night, although I don't remember checking for sure. I tried restarting the iPhone, but that didn't do anything. I haven't tried a restore yet, but I'm wondering if anyone else with this problem has a solution. Thanks.
iPhone 3GS (8GB), iOS 6
