Router is not showing selected DHCP clients including wired. For example, my Canon printer does not show up on the list of "Connected devices" but it works no problem whenever I need t print. I wanted to assign Static IP for this printer but I have no way to check its MAC, it's nowhere on the printer body, windows getmac neither Test Page won't return it. Thought Cisco router will shot it on the list but no.
Ideas?
