Why does ARP not show all devices?
You can try iterating over all the IP addresses on your network and pinging each one. That will force your computer to attempt to use ARP to map the IP address to the hardware address for each computer. You can also try pinging the broadcast address of the network ( ping 192.168. 1.255 in this case).

What does arp * command do?
The arp command is a tool that allows you to display the IP-address-to-MAC-address mappings that a system has built so that it doesn’t have to fetch the same information repeatedly for systems it communicates with. In doing this, arp allows you to discover and display details about systems on your network.
How do you resolve an incomplete ARP?
It is easy to check this: go to a Cisco device, check the ARP table, do a clear arp, and check the table again. It should have the same content (or very near to the same content) showing that it does not wait for another data packet to the destination.
