My apologies for not beig specific. In the router control panel, all the computers are listed by name, with the IP Addresses for each one. The only exception is the Amiga, in that it shows the IP Address, but lists the device as unknown. I can ping all the computers except the Amiga.
I have found the Ping command in Miami, but when I attempt to use it, the message reads Unable to open miami.library version 8.
AmiTCP-4.3 is also on thre machine, and I am able to start it, but I do not know its' function. There is also an icon for something called Samba.
All of the computers are connected to the router via an Ethernet cable, and the Amiga is able to access the internet.
I have another old PC running Windows 7 I brought out of storage, and it can ping the other computers, but not the Amiga.
I did run Tracert straight from the Search command. Will try the CMD shortly, as well as the Miaminetstat command and post the results. Thank you for your patience and assistance, it is GREATLY appreciated.
