Internet dropped out last 2 nights

So it is just once per day around the same time? This sounds like the DHCP lease is renewing at that time. Does the connection come back on its own or do you need to reboot the router? As there is no way to extend the lease I would suggest either rebooting the router at a time where you are not using the router, for example in the middle of the night. Otherwise if you set static IPs for your devices then they shouldn't lose connection.
