Netgear Nighthawk AC1750 not working

[Eyedesigns]

The lights are on but these are flashing- internet, 2GHz, 5GHz. Can not connect to WiFi. Rebooted. Cable guy checked and internet is fine. Says router went out. Only had it 2 yrs

What router? AC1750 is a speed, not a model.

What modem is it connected to? 

have you tried a simple factory reset and reinstall? push and hold reset for 7-15 seconds while its powered on. Then let it reboot and try installing it.

Model is R6700v3. I restarted it. It rebooted but I don’t know how to reinstall it??

You rebooted it but did you factory reset it? or just reboot it? 

here's where you can get the install manual.

Yes. I held down the reset button for 15 seconds. It’s working. The white light are supposed to flash when working right? Not stay on all the time? The cable guy said he has the same router and lights are supposed to stay on. ??? He also said I need to replace it but it’s working.
