How do I find a device’s MAC address?
You’ll need to know the MAC address for a device when:
• Assigning an IP address based on a MAC address (when using DHCP)
• Allowing or denying devices access to your Wi-Fi network (MAC filtering)
Tip: To display a list of connected devices, including the MAC address of each
device, go to the Mobile Hotspot Homepage, log in as Administrator, and click the
Wi-Fi icon ( ).
The steps for finding a device’s MAC address depend on the operating system.
Windows
1. Open the command prompt window.
a. Click Start > Run.
b. Type cmd or command and click OK.
2. At the command prompt, type ipconfig/all and press Enter.
3. Write down the Physical address for the entry that relates to the wireless
network connection. (It appears as a series of numbers and letters. This is the
MAC address of your wireless adapter.)
Mac OS X
1. From the Apple menu, select System Preferences > Network.
2. Select the wireless adapter that is connecting to the routing hardware.

4. Select Ethernet. The Ethernet ID is displayed. This is the same as the MAC
address.
