I have a wireless device on my router. I can see the device's mac in the router's DHCP table. My computer is also wireless to the router. When check the arp table via the computer, arp -a, the device is missing. I tried ping 192.168.1.255 but the request timed out. If I hardwire the computer to the router, I can ping .255 and the arp table populates with the missing device?
What's going on? Is there is router setting that I need to change?
