Want to enter the first backend after connecting Mercury Tenda routers in series? 192.168.0.1 When you reach the second station, you need to use these three tricks to find the superior house number.

On the day I was cleaning the internet cable at my father-in-law's house, I was distracted by something for ten minutes. His family has a typical two-level structure: The Mercury D191G in the living room is used as the main dial-up router. The Tenda AC12 in the study room connects the network cable from the LAN port of the main router to my WAN port. I then connect my phone to Tenda's WiFi and want to change the port mapping in the Mercury backend. Browser knock 192.168.0.1 , entering the Tengda backstage. Plug the computer into the port next to the main router, press 0.1, and it's still the Tenda page - that cable comes out of the Tenda LAN port and is managed by Tenda. I was sitting in the study, and there was a machine just across the backstage of Mercury, but I couldn't reach it.

The router is not to blame for this. After being connected in series (LAN to WAN connection method), the two stations are each independent small kingdoms.: Whoever you connect to WiFi will send you an IP, and your "gateway" will point to that person. Browser knock 192.168.0.1 , the system only regards it as an intranet address and asks the gateway. The gateway is Tenda. When Tenda saw that it was me, it naturally brought out its own backend. If you want to buy the Mercury one, you must first know where it lives in Tenda's eyes. This article writes down the three tricks I used that day in order. They are all zero-cost methods. The first trick is enough for most people.

Think about it first: The gateway only recognizes the next hop, and the upper-level route is not on this map.

Calculate the accounts before the investigation to avoid wasting your work. Connect your phone to Tenda's WiFi, go to Settings and scroll through the WiFi details page. You will see a "Gateway" or "Router" field. That address is Tenda's LAN port IP. There are a large number of tutorials on the Internet to teach you to "check the gateway after entering the backend". This trick is always successful in single-router households. After changing the LAN port IP, I forgot the new address. This is what I teach myself. But there is a natural blind spot in the two-level series structure.: DHCP will only tell you "who is your gateway", which is the machine above your head. It will not tell you who the gateway of the gateway is.

The Mercury main router is the "gateway of gateways" for Tenda devices. This information is not in the address you get on your mobile phone. So don’t scroll through the WiFi details page to find the main router, there really isn’t one there. By the way, you need to know which machine you are connected to is sending WiFi. It is most likely to connect to the wrong door in a home where optical, modem, router, and mesh are all mixed together. I can’t access the backstage article even though I’m connected to WiFi. Listed are five possible ways of making mistakes. First, make sure you knocked on the door correctly, and then proceed to the next three moves.

The first move: Enter the second backend and check the WAN port status. The main router door number is inside.

This is my most recommended move, it’s fast, accurate and smooth. Since you are connected to Tenda’s WiFi, 192.168.0.1 Access to Tenda's backend is smooth, and the main router information is hidden in Tenda's own ledger. Tengdajin tendawifi.com or 192.168.0.1 , after logging in, look for the "Internet Settings" or "External Network Settings" page (the old firmware AC series is in "External Network Settings", the new firmware is near "Network Parameters - Internet Settings"), there will be two lines of key information written on the WAN port connection status.: One line is the connection type "Dynamic IP/DHCP", and the other line is "IP Address/Subnet Mask/Gateway". That gateway is the house number registered by the Mercury main router on the Tenda WAN port side. The situation in my family is 192.168.0.1 ——Both machines have factory default segments, and the main router has not been changed.

Once you get this address, open a new tab in your browser and type it directly, and you will be dropped into the login box in the Mercury backend. The same goes for Mercury.: If the second router is Mercury and the main router is Tenda, enter melogin.cn , turn to the "Internet Settings" page, the gateway column of the WAN port status is also the answer. Pay attention to a detail: Does this trick require that the main router and the second router are not on the same network segment? Not required. Even if both are 192.168.0.1 , the gateway display read from the second background is 192.168.0.1 , you knock again 192.168.0.1 , it is the second station that enters - because DNS resolution and routing are managed by the second station. The series connection of two units in the same section belongs to the lightning connection method. How to connect two routers I strongly recommend staggering the network segments here, just to avoid confusion in today's scenario. The solution to a car crash on the same section is to first change the LAN port IP of one of the cars. Mercury Edition and Tenda version I wrote one article for each of the correction methods. After the correction, I came back and followed the first move.

The second move: Tracert on the computer, the second hop is the main router

The first step is to log in to the second backend. If you have forgotten your password or are too lazy to flip through the page, there is a more wild way on the computer. In Windows, press Win+R to enter cmd and type a line:

tracert 192.168.0.1

The list comes out with one line per line. The first line is your own computer (the starting point), and the second line is the router above your head—whose phone is connected to whom, and whose computer is plugged into it. This move has no effect on "finding the one above your head", and has the same effect as checking the gateway. The real way to play is to chase the external network address:

tracert www.baidu.com

The first hop is your gateway (second router), and the second hop is the main router. Because the traffic going to the external network must first pass through the second station and then be forwarded through the main router, the main router naturally stands at the second hop position. The IP displayed in that row is the house number within the main router pair. The advantage of this method is that you don’t need to touch any background, and everything is done from the command line. ； The disadvantage is that you need a computer, and the tracert that comes with Windows has to run for thirty jumps before it stops working. When you see the second jump, you can press Ctrl+C. The pronunciation of each jump and the meaning of the asterisk, The tracert article I have dismantled it line by line here and will not expand it here.

On Apple Mac, replace the command with traceroute, the same location. There is no ready-made tracert on the mobile phone. Some WiFi toolbox apps claim to have route tracing, but in fact it is restricted by the system in the new version of Android. Don’t expect it, it will be faster for mobile phone users to just take the first step.

The third move: Use the brand app to check the topology, or simply go to the main router.

If both methods are too troublesome, there are still two ways to go. Mercury's MERCURY App and Tenda's App both support the management of local routers. After logging in, some versions can display the "upper-level device" or directly draw the IP of the main router in the network topology diagram, and you can jump to its management page with one click. The firmware of this function varies greatly between versions. I found it once in the Mercury App, but after upgrading two versions, I couldn't find it again, so it should only be used as an alternative, not as the main method.

The last one is the stupidest and the most stable.: People walk to the main router. Take your mobile phone and connect it to the main router's own WiFi (the signal sent by the Mercury in the living room), check the gateway in the WiFi details, that is its house number ； Or simply find a network cable and plug the computer into the empty LAN port of the main router. Look at the gateway in ipconfig. On the trip to my father-in-law's house, I went around and around and used the first trick to get it done. After that, I reflected on it.: There are only a dozen steps from the study to the living room. I held my phone and fiddled with it for ten minutes. A common problem among technical people is that they always want to solve problems that can be solved in two steps across a two-level network.

After finding: Three relapse prevention actions, completed in one go

The door is found just to stop the bleeding. To avoid confusion, I suggest you do three things on the spot. The first thing, Change the main router LAN port IP to an uncommon segment . Both are 192.168.0.1 In the structure of , the word 0.1 is ambiguous - if you type it, it will always be "the one closest to you". Change the main router to 192.168.2.1 (or any segment different from the second level), which backend to enter in the future, the address itself is the answer, no need to guess. The cost and chain reaction of change are Change the five accounts of the network segment I’ve done the math in that article, so go through it before taking action.

The second thing, Do not set the account and password of the two backends to be the same. . I have seen too many families set weak passwords at the admin level for all two-level routers. When there is a problem and you need to distinguish "which router I am logged in to", the same box will pop up on both routers, doubling the confusion. You can also easily distinguish the WiFi name from the main router in the backend of the second station, not to mention that the three networks at home are all called MERCURY._9F2C is such a coincidence, the screen is on the wrong channel, 5G frequency band cannot be found When checked, they are all distractions.

The third item, Keep a home network cheat sheet . The models of the two machines, their respective LAN port IPs, and management passwords were written in the weak current box with sticky notes. This is a trick, but it saves lives more than any other technique. If you don't touch something like the backend address for three months, you will forget it. 192.168.0.1 Can't get into that one 90% of the problems were caused by the first three mistakes. The root cause was "misremembering the house number." A cheat sheet for weak current boxes is posted, and everyone in the family can follow it into the backstage. It is a hundred times more realistic than teaching parents to tracert.

ending: When it comes to finding the backend, order is the answer

Condens this article into one sentence: Whoever checks whom has to go to the next level to read the ledger of the lower level. In a two-level home, the router you want to access is never silent. It registers its house number in the WAN port status of the subordinate router, in the second hop of the tracert, and in the gateway of its own WiFi - there is always one of the three places you can reach. First the first move and then the second move, it only takes two minutes. If both ends are really blocked (for example, the second backend password has been forgotten), don’t forcefully guess the address. Walk to the machine and start over from first principles.: Connect to its WiFi, check the gateway, and enter.

What a long-winded sentence about boundaries?: This method describes the serial connection method of LAN to WAN. The two devices are separated by NAT, so there is a blind spot of "the lower level does not know the upper level". If the second station in your home has been changed to AP mode (the kind where LAN to LAN and DHCP are turned off), then there is only one network for the whole house. The main router comes out after checking the gateway. There is no problem in finding it. How to adjust the second station to AP? The article about two series connections The second connection method is written very carefully. Choosing the right structure is less troublesome than learning any backstage skills.
