Modem with router - My PC is connected to the internet but won't connect to my wifi

I shut my computer off for a day and when I turned it back on - I lost my wifi connection. I am at my wit's end! I reboot both the modem and the router. I have internet access on my PC just fine, but my PC as well as all my other devices won't connect to my wifi. I am using the correct password. When I open the Netgear home panel, everything looks good, except the wifi says "not connected". I can't connect to my wifi to save my life! Everything appears to be physically connected just fine. Any help is greatly appreciated!
