I added the Deco mesh router system (Wifi 6 with three units) to my Netgear 3700 cable modem.  After having the Deco router system up and running I was confused about how to turn off the router functions of the cable modem.  Finally I found the toggle check boxes to disable the router function and toggled it off.  Seems to be what I needed to do.  However now I cannot access the Netgear cable modem web page (192.168.0.1).  Would that be due to switching the router function of the cable modem off??
