Nighthawk CAX80 working but only top two lights are lit
I just bought this modem/router and finally got it hooked up and running. It is a 'Renewed' from Amazon router. Only one very small mark on the front just above the two switches. After yesterday ...
Well singles look good.
Some Criticals and a couple of Errors in the events logs that the ISP should review and resolve.
I would presume that there maybe a HW fault with the LEDs.
Last resort would be to try a 30-30-30 reset on the modem with out the coax cable connected, then reconnect when the first LED turns on WHITE, then see if the rest of the LEDs turn ON. WiFi LEDs should turn ON as well.
If not, then would be a HW fault. Up to you to keep it or return it to place of purchase.
Please post a picture of the front LED panel.
Look at the online user manual to see what the front LEDs mean and behaviors:

Has a factory reset on the modem been performed and setup from scratch?
Whos is the ISP that your connected with?
The lights are the power light and the Downstream light.
