Netgear CM1100 Modem will connect to mesh wi-fi, but not a router or computer.

My ISP was recently purchased by Breezeline (was WOW). Now my modem will not provide a signal to any wired devices connected to it. It is on and providing an internet connection (as evidenced by its connection to my eero mesh). The wi-fi mesh works in either port. When I try to connect a router, or computer directly the port light turns orange and it will not provide a connection. I have tried multiple computers & routers, and switched cables multiple times.
Tried the online support (useless - had already done all of that) hoping they would connect me with someone who knew something other than the online troubleshooting guides. I suspect it is something the ISP is doing for security but there is nothing online about having to use their routers.
Modem Netgear CM1100, Router Netgear R6400 - latest firmware, (also tried TP link router and older linksys router as well)

Be sure that the R6400 router is the only device connected to the WAN #1 port on the modem. The other WAN port can not be used.
Power OFF the CM modem and R series router for 30 seconds then back ON with the CM modem first, then the R series router.
Connect ALL other wired and wireless devices to the R series router.
If you have a Wi-Fi MESH system, you might put this in place with the R series router and use the MESH system instead of the R series router.
Be sure your using good quality LAN cable, CAT6 is recommended.

Thank you will try this when I return home. I'll leave feedback on how it works.

Re: Netgear CM1100 Modem will connect to mesh wi-fi, but not a router or computer.
Thank you for the advice. Finally got to it today. I rebooted using only the router plugged into the port. Worked without a hitch. R6400 handling the wired traffic with the wi-fi disabled. Mesh net handling the wi-fi.
I have used both ports in the past so I was still under the assumption that I could. Saved me a ton of frustration!

Power cycling WHILE ATTACHED to my 3rd part router really helped me with an issue I was having with my CM500-100NAS as well.
Thank you!
