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).
How do you display ARP entries?
To display the arp cache entry for a specific IP address, use arp /a with the inetaddr parameter, where inetaddr is an IP address. If inetaddr is not specified, the first applicable interface is used.

How do I view an ARP table in Windows?
To display the ARP table on a Unix system, just type “arp -a” (this same command will show the arp table in the command prompt on a Windows box, by the way). The output from arp -a will list the network interface, target system and physical (MAC) address of each system.
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.
Why can’t I see other computers on my network?
Restart your computer, open the Network and check if nearby Windows computers are displayed.

Then you need to reboot the computer.
