Netgear Nighthawk AC1900 R700 Devices cannot locate my network

[mamatin]

No wifi in the house. Network status. I cannot connect any wireless devices like a wireless printer and error says Not connected to a network. My other device gives me available network except for mine. Please help, my kid needs wifi for school and finals coming up. Thank you

A little better description might help. 

I'm not sure if its just one device having issues, all devices, or what exactly is going on. 

So a bit more clarity there would help. 

also, what are the led's on the router showing for wifi?

Did something change with it? 

Do wired devices work?
