Network Interface Cards (NICs) used in computers are hard-wired with a hardware address called a Media Access Control or MAC address. Routers and other network devices use this address to enable the computer to communicate on a sub-network or network. MAC address - Media Access Control address.MAC addresses - hardware addresses that uniquely identifies each node of a network. It is assigned by the vendor or manufacturer and saved to the device memory. Best Answer: In short, you can't. In long, you can, but it takes some work. It really depends on the type of modem you have. Most newer modems require a JTag and some solder to hack, allowing you to change the MAC address on command.
A Motorola cable modem comes preconfigured with a MAC address that is unique to your device. This MAC address is used to identify your modem as well as communicate with devices such as a router. If your Motorola cable modem fails to work with your router, you may have a communication problem due to a conflicting MAC address. With more recent cable modems, the MAC address the websites report is *larger* than an ordinary MAC address, because it is in three parts! 1 The first part is the MAC address (of the router) which I can manually I change from time to time.

For a validation process I need to know the MAC address of a cable modem. (I do not need to know the MAC address of the network adapter.) The cable modem though is placed somewhere hardly accessible, so I want to avoid physically touching it to read its sticker.
What I do have is a Windows 7 machine connected to it, so I want to look up its MAC address via power shell. How do I achieve that?

Program Modem For Mac Address Checker
If the modem has an assigned IP address, you can find the MAC address using the
ping
and arp
command:- Ping the device:
ping 1.2.3.4
- View arp table:
arp -a
Comcast Modem Mac Address
The MAC address information is pulled by the ping command, and the info is temporarily stored in your NIC. The arp command is to show the stored information.

Assuming you want the WAN MAC address. Many cable modems have a configuration or status page. For Comcast modems, it is typically 192.168.100.1. If your modem is also your router, it will be your LAN gateway address. Here's what I get when I open 192.168.100.1 on my cable modem:
Sorry, I don't know how to do this with powershell.

If the modem has a local address in the LAN you're connected to and you know it, then you could use the
arp
command to see its physical address.arp -a
lists all discovered addresses.For more usage of the
MosesMosesarp
command, you can type arp /?
