To try and put your mind at rest regarding this statement:
The scanner turned up 7 active IP addresses from the previous IP range 192.169.X.XXX that have no mac addresses.

OK, but here is a simple non-technical thing that you can do that may provide potentially useful information.
One of the many services that will do an inbound scan from the internet to see if there are any holes in your inbound firewall protection.

Use the first 'Proceed' button, then select the 'All Service Ports' option.
Wait for the scan result, hopefully all green.
