I recently purchased Netgear CM1100 docsis 3.1 gb modem. More than I need (100 mb isp plan currently) tried to pair it with my existing router via Ethernet connection. Router is a linksys ea6350 dual band router. Is there potential for any compatibility issues with these two devices or am I missing something. Activated new modem with my isp and get internet direct, but when I added the router to the mix I wasn’t able to get WiFi setup, my router kept flashing like it wasn’t getting any signal.
