How can I determine what a device is on my network
I'm a new user and need to locate my Tivo recorder on the network to open ports for it to work (everything else is working). When the devices were added to the network some have weird names that are impossible to decipher. How do I determine what hardware device is 09AA01C291602MU or BRW5413799F9437 - a google search turns up nothing? I need to point the open ports to the correct device, right?
