The full name of mac clone is mac address clone, which is the physical address solidified in the serial EEPROM on the network card, usually 48 bits long. Mac cloning is generally used on routers. Users use computers to directly dial up the Internet. Later, they add a router and use the router to enable multiple computers to access the Internet at the same time. At this time, mac address cloning is used, which is to copy the mac of the current computer. Clone the address into the router. Because the operator binds your computer's mac address to your account, you have to clone it before you can use it.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
Mac clone, that is, mac address clone, is the physical address solidified in the serial EEPROM on the network card, usually 48 bits long. The Ethernet switch implements packet switching and delivery based on the MAC source address and MAC destination address in the header of a certain information packet. You can fill in the MAC address of the current management PC into the "MAC Address" column. Note: Only computers in the LAN can use the "Clone MAC Address" function.
Generally used on routers. For example, if you now use a computer to dial up the Internet directly, and later added a router, you can use the router to enable multiple computers to access the Internet at the same time. In this case, you need to use mac address cloning. It means cloning the current computer's mac address into the router. Because the operator binds your computer's mac address to your account, it must be cloned before it can be used.
The MAC address is the physical address solidified in the serial EEPROM on the network card, usually 48 bits long. The Ethernet switch implements packet switching and delivery based on the MAC source address and MAC destination address in the header of a certain information packet. You can fill in the MAC address of the current management PC into the "MAC Address" column. Note: Only computers in the LAN can use the "Clone MAC Address" function.
The MAC address is the physical address of the network card. Each network card has a unique MAC address. Although this address cannot be changed, the system can be deceived through software.
Clone is to reproduce an identical one
The main purpose is to share the Internet.
Don’t some operators prohibit the use of routing and only allow one machine to access the Internet? After cloning, the addresses of all ports on the router will be the same, and it will be regarded as only one machine.

mac address cloning: a method to solve the problem of broadband client restricting router sharing Internet access
Method 1
First Make sure that the computer you apply for Internet access can access the Internet in stand-alone mode. It means that the MAC address of the computer's network card is a legal MAC address.
Enter the system's MSDOS mode and issue the ipconfig/all command to find the MAC address of the computer's network card. For example: 00-50-8D-D1-71-A7.
Looking for legal MAC addresses
Unplug the external cable from the network card of the stand-alone computer and insert it into the WAN port of the broadband router; connect the network cards of multiple clients to the LAN of the broadband router port is connected.
Turn on the power of the broadband router. Start the IE browser on the client computer that was previously able to access the Internet.
Type the IP address of this broadband router in the address bar of the IE browser to enter the router's Web settings page.
Click the "Network Parameters" button in the left window of the configuration page and select the "MAC Address Clone" button.
The "MAC Address Clone" window appears.
In the "MAC address of current management PC" window, fill in the "legal MAC address" found above:
00-50-8D-D1-71-A7.
Click the "MAC Address Clone" button again, and the MAC address will be filled in the "MAC Address" window. Finally, restart the router for the settings to take effect.
In this way, the router obtains a legal MAC address bound by the ISP. This allows multiple computers to share the Internet.
Note: The "Clone MAC address" button on some routers is called "clone mac" in English.
Attachment: Modify the MAC address of the network card.
Experience has proven that you can share the Internet by modifying the MAC addresses of all computer network cards in the LAN.
Method 2
In order to limit the number of access users, some broadband providers bind MAC addresses on the authentication server. At this time, you can first connect the computer with the bound MAC address to the router LAN port (but do not connect the router to the modem or the wiring provided by the ISP), and then use the router's MAC address cloning function to copy the MAC address of the network card to the broadband The WAN port of the router.
Method 3
Use the "MAC address cloning" function of the broadband router to break through the address binding of the broadband provider and enable multiple computers to share the Internet.
Take the TP-Link TL-R400 small router as an example. After entering the router's Web settings page from the computer with the bound MAC address, select "Preliminary Settings" under "Basic Settings" in the main menu, click the "Modify" button in the "WAN Interface Type" column, and then select "Dynamic IP".
After saving, return to the "Preliminary Settings" page. There is a text box after the option in the "WAN MAC Address" column. The content in it is the MAC address of the machine. The user can modify the MAC address directly in the text box. , fill in the bound network card MAC address here. If you do not know the MAC address of the network card, you can select the "Clone MAC (MAC Address Clone)" button to directly clone the MAC address of the current computer's network card to the WAN port of the TL-R400. After saving, restart the router to take effect.
