When I try to plug in the Ethernet cable from my computer into my router, I just get the little yellow warning triangle, but when I plug the Ethernet directly into the modem, the internet works perfectly on this computer, but only for this computer. The Wi-Fi won't work on any device in the house, I even have another computer plugged into the router (Ethernet) and now that computer is getting the little yellow warning triangle.
Router: Netgear Nighthawk R7000
Modem: Cisco Model DPC3825
