lost wi-fi connection with cable modem-router model C3000

[maidie]

I've been using this for a few years with no problem and yesterday, I didn't have wi-fi.  All I know is that all the green lights are no longer on.  The top two and the bottom one are off.

the top 2 are wps and wifi on/off. 

the bottom one is usb. 

Push and hold the wifi on/off button for a couple seconds. Maybe it got hit and turned off. 

do wired devices work?

Thanks for answering.  Yes, the wired devices are working.  Pressing the wifi button on the router didn't help.

You have to push and hold it. 

Was the wifi disabled in the settings?
