+The MAC Address menu has settings to let you electronically change (or "spoof") the MAC (Media Access Control) address of various network interfaces.
-Note that this function does not change the hardware MAC Address in the actual device chip. It just overlays the different address in software.
+Note that this function does **not** change the factory-assigned MAC Address in the device's chip. It just overlays the different address in software.
+For common device names in FreshTomato, see the [[:faq|FAQ]] page.
 **WAN Port:** In this field, you can enter any valid MAC Address to be assigned to the WAN interface.
-   * Default: This option leaves the MAC Address as the fixed factory hardware address burned in to the device's chip.
+  * Default - This option leaves the fixed, factory-assigned MAC Address as the interface's MAC Address.
-  * Random: Choosing this option assigns a random MAC Address to the device
+  * Random - This option assigns a random MAC Address to the device.
-  * Clone PC: Choosing this option assigns the same MAC Address used by the hardware client connecting to the Tomato router.
+  * Clone PC - This assigns the same MAC Address used by the interface of the client currently connecting to FreshTomato's web admin interface. \\ Some cable and other Internet providers authorize your cable modem and devices based on its MAC address. Every network has a unique address. When your modem requests an address from the Internet provider's DHCP server, the Internet provider will either grant it or deny it access to the network based on it's MAC Address.\\  \\ {{https://wiki.freshtomato.org/lib/plugins/ckgedit/fckeditor/userfiles/image/wiki/macaddress.jpg?983x301&nolink|wiki.freshtomato.org_lib_plugins_ckgedit_fckeditor_userfiles_image_wiki_macaddress.jpg}} \\  \\  \\ Some cable companies also authenticate the network card in your PC/client device after you've logged onto their network. They do this to prevent you from using any LAN client device other than the first one you used (whose MAC Address is regstered with them) using their service with out paying for it. By doing so, they can force you to use the same client device you've always used.   \\  \\ If the provider's network detects a different MAC Address than the one associated with the original client device, it will deny your client device access to the network.  It will only allow devices known to them, in good standing. However, If you let FreshTomato clone your original client device's network MAC Address, it will fool your cable provider into thinking you're still using the same PC/client device interface to access their services, and your router will be allowed on their network.  They don't really care which device you use, the MAC is actually associated to your billing account.  Often you call them and let them know you have a new device and they will change the MAC in their system.
-Many cable-based Internet providers authorize your cable modem based on its MAC address. Every DOCSIS cablemodem has a unique address. When your modem syncs with the Internet provider, the Internet provider will either grant or deny it access to the network based on it's MAC Adddress.
+**Note:** Starting with FT release 2021.8, WAN Port will use a different/new default MAC address based on the eth0 / LAN MAC address.
-Some cable companies, for some reason, also authenticate the network card in your computer. First it will authenticate the Cable Modem, and then when your computer attempts to get online, they'll check and make sure that you're still using the same computer/network card/etc that you've always used. **If you've changed your network card or installed a router, they will deny you access to the Internet. **
+__Set wanX MAC addresses after wireless VIFs (all in one line now):__
-This is why most cable routers have a **"MAC Address Clone" (Use Computer MAC address) feature**. If you tell your router to clone your network card's MAC Address, it makes your cable provider think that you're still using the same computer/network card to access their services, and therefore they allow your router on the network.
