Nighthawk R7000 suddenly lost internet connection

I've got a R7000 router that is on the latest firmware (V1.0.11.128) that suddenly stopped connecting to the internet (internet light is orange). I've reset it, powered it and the modem off for two minutes then turned them back on, and nothing is working. I can hardwire to the modem and get it connected, but nothing seems to work on the modem. I've also tried multiple ethernet cables to see if that might be the issue with no luck. Note that I was running a combo in bridge mode, and I've temporarily turned the router portion back on to continue working using wifi for the time being, but  I don't think that would have any impact on the issue. Any ideas on source of the problem and resolution steps? 

  • The startup sequence between the router and the gateway can be important.  Remove the power connection from each.  Restore the power to the gateway and give it ample time to boot and stabilize.  Now restore power to the router and give it ample time to boot and stabilize.  The time required for these devices to boot and stabilize is often several minutes.  Two minutes is not enough.

     

    It the above sequence is not successful, repeat with just the opposite.  Power on the router first, wait for it to fully boot and stabilize before powering on the gateway.  Both of the startup sequences should be done with your gateway in bridge mode.

    Has a factory reset and setup from scratch been performed since last FW update?

     

    Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
    Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
    Be sure your using good quality RG6 coax cable up to the modem. 
    Be sure to power OFF the modem for 1 minute then back ON.

    Be sure to use a good quality LAN cable between the modem and router. CAT6 is recommended.
