[QUOTE="MacInWin, post: 1778209, member: 396914"] Not to make any suggestions, but maybe to trigger thoughts: What Paul is looking at are the IPs that have been ASSIGNED by the DHCP server in the router to devices it sees. The wifi ones use the password to control who gets an IP address, so his changes to that function have worked for wifi, but passwords are not used for directly connected devices. I think the rationale is that if a cable is plugged into the router, the person who owns the router knows and trusts the other end of the cable. Hence, the printer appears even after the password is changed because the password is for WiFi, not cables. So, Paul, are there any other cables plugged into the router? Bear in mind that what you probably have is a combination modem/router, so the cable company line (usually coaxial cable) is connected that is the feed from outside the home and goes to the modem portion of the Arris. Internal to the modem/router, the modem part connects to the cable system, receiving and transmitting signals on their system.
