This article introduces the relevant knowledge of "what is the meaning of mac cloning". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The MAC address is the physical address of the network card, and each network card has a unique MAC address. Although this address cannot be changed, the system can be deceived by software. Cloning is to regenerate into an identical one, the main purpose of which is to solve the problem of broadband clients restricting routers from sharing Internet access.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

It is generally used on routers, for example: you now dial up the Internet directly with your computer, and then you add a router to achieve multiple computers surfing the Internet at the same time through the router. At this time, you need to clone the mac address, that is, to clone the mac address of the current computer into the router, because the operator binds your computer mac address to your account, so you have to clone it later.

A MAC address is a physical address that is solidified in a serial EEPROM on a network card and is usually 48 bits long. The Ethernet switch exchanges and delivers packets according to the MAC source address and MAC destination address in a packet header. You can fill in the MAC address of the current management PC into the "MAC address" column. Note: only computers in the local area network can use the Clone MAC address feature.

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 by software.

Cloning is to regenerate into an identical one.

The main purpose is to share the Internet.

Don't some operators prohibit the use of routing and let only one machine surf the Internet? After cloning, the address of each port of the router is the same, and it will be treated as if there is only one machine.

Mac address cloning: a way to solve the problem of Broadband clients restricting Router sharing Internet access

Method one

First make sure that the computer applying for access to the Internet has been able to access the Internet in a stand-alone state. It means that the MAC address of the computer network card is a legitimate MAC address.

Enter the MSDOS mode of the system, issue the ipconfig/all command, and you can find the MAC address of the computer network card. For example: 00-50-8D-D1-71-A7.

Looking for a legitimate MAC address

Unplug the external leads from the network card of the stand-alone computer and plug them into the WAN port of the broadband router; connect the network cards of multiple clients to the LAN port of the broadband router.

Power on the broadband router. Launch an IE browser on a client that previously had access to the Internet.

Type the address of the broadband router IP in the address bar of the IE browser to enter the Web settings page of the router.

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.

Fill in the "legal PC address" found above in the window "current MAC address of Management MAC":

00-50-8D-D1-71-A7.

Click the "MAC address Clone" button and the MAC address will be filled in the "MAC address" window. Finally, restart the router for the settings to take effect.

This gives the router a legal MAC address bound by ISP. Multiple computers will be able to share the Internet.

Note: the "clone MAC address" button of some routers is "clone mac" in English.

Attached: modify the MAC address of the network card.

Experience has proved that changing the MAC address of all computer network cards in the local area network can also share the Internet.

Method two

Some broadband providers bind MAC addresses on authentication servers in order to limit the number of access users. At this point, you can first connect the computer bound with the MAC address to the router LAN port (but the router does not connect to the wiring provided by Modem or ISP), and then, using the router's MAC address cloning function, copy the MAC address of the network card to the WAN port of the broadband router.

Method three

Using the "MAC address cloning" function of the broadband router, it breaks through the address binding of the broadband provider and realizes the sharing of multiple computers on the Internet.

Take the TP-Link TL-R400+ small router as an example. After entering the Web settings page of the router from the computer where the MAC address is bound, select preliminary Settings under basic Settings on the main menu, click the modify button in the WAN Interface Type bar, and then select dynamic IP.

After saving, return to the "preliminary Settings" page. After the options in the "WAN MAC address" column, there is a text box in which the content is the local MAC address. Users can modify this MAC address directly in the text box and fill in the bound MAC address of the network card 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 network card of the current computer to the wide area network port of TL-R400+. Restart the router after saving it and it will take effect.
