Hi I have an M5  that seems to randomly drop the wifi throughout the day. I have it connected to a Netgear N600 model c3700 which is a modem/router. I currently have the router on the N600 turned off so that the deco is the only option. For some reason at odd points throughout the day the deco will lose its wifi signal. I have power cycled the modem and unplugged the deco to reset them, which occasionally fixes the problem. Other times though it will drop the wifi and then randomly it will be back. Could this be due to it being connected to a router/modem combo? Or is the modem just old and maybe I need s new one? It is like 5 years old now. 

Thanks
