C7000v2, Android, wi fi signal stopped

[Braadford1]

Have had this modem/router for about a year with no problems.  Today while watching TV the picture stopped transmitting.  Tried to reconnect via Roku and could not find a wi-fi signal.  Unplugged and plugged power to the router and all lights come back on, and then 2.4 Ghz, 5.0 Ghz, WPS, and Wi-Fi lights turn off.  All other indicators are solid green.  Also did a reset, all lights come on, downstream, upstream, internet blink for awhile then go solid, all other indicators except ethernet  go dark.  Thanks for any help.

Do wired devices work? 

Did the wifi on/off button get hit? Push and hold it for 2-3 seconds.

I am not sure if I have any wired devices.  The printer is wireless, which is not working at this time, and the internet is working.  I pressed the wi-fi button but nothing happened.

You pushed and held it for at least 2 seconds? Not just clicked it? 

Try a hardwired device to see if the c7000 is still working and if you can access the gui

Yes, I have held the wi-fi button for more than 2 seconds.  What would be an example of a hardwired device? I know what GUI stands for, but not sure what you mean about accessing the GUI?.  What could possibly have the modem/router suddenly stop working while sending a signal?  Could it be possible that the modem/router is going out?  I appreciate your help with this, and have to confess that I am mildly literate with hardware and apps, so my questions may seem elemental.

hardwired just means a device connected via ethernet. You can log into the router through the browser and check the ssid (wireless name) settings and to see if they're enabled
