WOL recently stopped working for Static IP PC attached to R7000, Telnet to R7000 update ARP ?

WOL from a laptop was working on my network for the one PC (hardwired to a switch, which is hardwired to the R7000) with a static IP address for the past three + years. Recently, WOL stopped working.  I tried both connecting the connecting laptop to both LAN and Wireless, no go. I came across the following post here on Netgear Community and like to try the Telnet and setting the ARP, but telnet does not seem to connect to the R7000.  How can I ensure Telnet on R7000 is enabled?
