Where to set up router MAC address cloning? I changed my broadband account and password to a new one, but I still can’t dial up.

Last month, I replaced the router for Lao Zhou downstairs. The broadband account number and password were all copied word by word from the old backend. After installing the new machine, I couldn't dial it in. The page only responded with "Server not responding." He first called customer service, who asked him to wait, restart, and change his password. He struggled until eleven o'clock with no result. Later, I cloned the MAC address of the new router into the WAN port MAC of the old router, saved it, turned off the power, and then on again. It took three minutes to connect. Today I will explain the process clearly based on this pitfall.: First determine whether it is MAC binding, where to copy the old MAC, how to set it up in the new router, and how to choose among the three options.

Make it clear first: The broadband account not only recognizes the password, but also recognizes the MAC of the device dialed for the first time.

There is a WAN port on the outward side of the router. The WAN port itself has a MAC address, which can be understood as the "ID card" registered by the router in the broadband computer room. When fiber optic broadband is opened in many provinces, the computer room will record the MAC of the device that successfully dialed for the first time, and this account will only recognize it in the future. It’s true that the account password is the key to the door, but the computer room asked one more question.: Is this the machine I recognize?

So the old route can be dialed by plugging it back in, but the new route cannot be dialed no matter how hard it is. The passwords on both sides are still exactly the same. This is basically where the problem lies. The MAC address and the IP address are not the same thing. One is more like the factory number, and the other is more like the house number that was issued later. I am What does MAC address mean? I have said it before and will not repeat it here. What really needs to be remembered is: When replacing a new router, if your broadband account was previously bound to a device, you must either move the MAC address of the old device over, or ask the operator to clear the binding first.

Another situation that is easy to get confused is that the account number simply fills in the wrong way to access the Internet. The broadband account password is usually dialed through PPPoE. If you select dynamic IP in the first step of the router wizard, you will not be able to dial it, but the symptoms are different. You can check first. How to choose between PPPoE, dynamic IP and static IP Check it out. If the account number, password, and Internet access method are all confirmed and it still doesn't work, check the MAC binding line again.

Don’t rush to find the entrance yet: It will take ten minutes to confirm whether it is MAC bound.

MAC cloning is not a universal switch. Please go through the following three things before doing it. All three are successful, that’s basically it ； It’s worth trying if you win one. It doesn’t cost anything anyway.:

• When the old router is plugged back into the optical modem, dialing can be made normally, but the new router cannot dial using the same account and password. ；
• Errors such as server no response, 651, and 678 appear repeatedly in the logs of the new router. It is not a simple 691 password error. ；
• If you connect an old computer with Internet access directly to the optical modem dial-up, it will work, but if you change it to another computer or a new router, it won't work.

I wrote a separate article on how to assign responsibility for the error code in the second item. What do broadband errors 678, 691, and 651 mean? , you can check it if you are in a hurry. Just grab a judgment here: If the password is wrong, most of the time it is 691. Just change the password. ； If the server is unresponsive, 651, and 678 are coming in turns, and the old device is normal, don't waste time on the password and check the MAC.

If you're really not sure, just call the operator's customer service and ask.: 「Is my broadband account tied to the device MAC? 」Telecom 10000, China Unicom 10010, China Mobile 10086 are all acceptable. Some customer service staff don’t understand it the first time, so they will try another sentence.: 「I want to change the router. Please help me unbind the MAC of my broadband account. 」There is no charge for this step, and asking clearly can save you half an hour later.

Where can I buy my old MAC?: Only recognize the WAN port status page, do not copy it into LAN port

If you copy this step incorrectly, it will be all in vain. There is more than one MAC in the router, and the LAN port, WiFi, and WAN port each have their own. The computer room recognizes the WAN port. Take the old router and go into the background, look for the operating status, network status, and WAN status pages, and look for the words "WAN port MAC", "Internet port MAC" or "WAN MAC".

In the machines I have touched, the common positions are roughly as follows::

When copying, please note that the format is six groups, two digits per group, separated by colons, like 00:1A:2B:3C:4D:5E . Some people regard the letter O as the number 0 and I as the number 1. It doesn't matter if they fill in the wrong words. A more common mistake is to copy the MAC of the LAN port, which is equivalent to giving the number of the intranet side to the computer room, but the dial-up is still rejected.

The old router can no longer enter the backend, and the sticker on the body only has a MAC printed on it. Don’t try your luck with the one on the sticker. Most of the stickers print the LAN port or wireless MAC, which is different from what is bound to the computer room. In this case, go directly to the operator to unbundle it, which is faster than guessing.

Where to set up new router MAC address cloning: The five backend paths are all different.

After getting the new router, the phone connects to its WiFi and the browser enters its own management address. The clone entrance is basically near "Internet Settings", but the names of the brands differ by one or two characters, so I compared the common ones.:

If I can't find it, I browse through the first-level menus of Advanced Settings, System Tools, and Network Parameters. The names are nothing more than "MAC Clone", "Physical Address Clone" and "WAN Port MAC Settings". Because the Xiaomi device cannot be accessed in the App, I have to use the computer version of the backend. I wrote a separate article Where to set up Xiaomi router MAC address cloning , I happen to have Xiaomi in hand, so I can just follow it. Same goes for other brands: If the mobile website doesn't work, change to a computer and change the browser address to the backend address. Don't look for it in the App.

After the entrance is found, the page usually gives three options, which are described one by one below. Before setting up, first write down the old WAN port MAC you just copied in a note. Don’t fill it in while flipping through the old route, as it is easy to copy the MAC address.

How to choose among the three options: Default, clone local machine, customize old MAC

There are usually three types of MAC address cloning pages:: Default MAC, cloned local MAC, custom MAC. Many people make mistakes here, especially the "clone local" option.

When replacing a new router, the third level is the best choice.: Customize the MAC and enter the WAN port MAC of the old router. Why not "clone this machine"? Because what you are using to set up now is a mobile phone or a new computer, its network card MAC is completely different from the WAN port of the old router. Clicking "Clone this machine" is only suitable for one situation: When broadband was first installed, a computer was first connected to the network cable to dial the number, and then the router was connected. The computer room recognized that computer. Most families have long forgotten which station it is, so they can’t help guessing.

If the operator clearly says that it is not bound, or has just unbundled it for you, then just leave it as default. No need to clone, the new router can dial it by itself. Don’t reverse the order: First ask if it is bound, and then decide whether to fill it in. Don't click clone this machine as soon as you enter the backend, which will complicate a simple problem.

Don’t look at the light immediately after saving: Power off and restart in this order. If you still can't dial, ask someone to untie it.

After filling in the MAC and clicking Save or Apply, the most taboo thing is to stare at the phone and wait for it to communicate on its own. The old session is still hanging in the computer room. Both the optical modem and the new router need to be powered off to refresh the status of both sides. The order is as follows:

Save the MAC cloning settings of the new router first, and don’t rush to unplug it. ； The optical modem is powered off, wait 30 seconds and then plug it back in ； The new router is powered off, wait 10 seconds and then plug it back in ； Power on the optical modem first and wait for the registration light and PON light to stabilize, usually about two minutes. ； Then power on the new router and wait for it to dial up on its own.

I've suffered a lot in this order. At that time, Tu Kuai only restarted the new router, but the optical modem was not touched. As a result, the server was still unresponsive. Later, both were powered off once and then turned on again. There is no need to think too deeply about the principle. It is to ask the broadband computer room to put down the old session, and then let the new router register again with the old MAC.

If you still can't dial it in this order, you can't copy the old MAC, and you can't access the old route, don't restore it to factory settings over and over again. Factory reset will clear other settings in the new router, but the old MAC will not grow back on its own. Call the operator's customer service directly, report your broadband account, and ask them to do a "MAC unbinding". After unbinding the new router, leave the default MAC before dialing. If there is really a line problem, the customer service will tell you, which saves time compared to trying randomly in the background.

In the end, I will give you an accurate judgment.: The old route can enter the background, copy the WAN port MAC to the new route custom file ； If the old route cannot be accessed but the broadband is not bound, the new route will be left as default. ； If you are not sure, call customer service first to ask about binding. These three sentences cover the vast majority of dial-up failures when switching machines, and the rest is the fault of the network cable, optical modem, and line.
