Does the Mercury router setup not match the tutorial? The new and old interfaces are two separate menus, and I've mapped both frequently used function locations on both sides

last week, after helping my cousin's D191G change its DNS, I casually dug out an old MAC1200R that's been gathering dust in my drawer for years, hoping to switch it to a relay to supplement the signal for my study. But after scrolling through 'Advanced Settings' in the backend of an old machine, I spent ten minutes — and those four words didn't appear at all. I clicked through the menu from top to bottom, and every page didn't match the tutorial screenshots. At that moment, I realized that Mercury's backend consisted of two completely different interfaces.

1. Mercury really has two different interfaces; the official tutorials are written separately

cousin's D191G is a first-generation cloud router. When melogin.cn you enter the browser, the homepage shows several large cards and a "Advanced Settings" button in the top right corner. Clicking it reveals the network parameters and wireless settings menus, which are set away. But my old MAC1200R was a whole different world inside: on the left was a vertical text menu, running status, settings wizard, network parameters, wireless settings, DHCP server, forwarding rules, IP bandwidth control, system tools—all arranged from top to bottom, with all functions laid out in the open.

this isn't a machine malfunction. For the official Mercury service support document, I wrote two separate tutorials for the 'New Interface' and the 'Old Interface.' The new interface articles all start with the original sentence: Different Mercury routers may have different setup interface styles. For different interface styles, please refer to the old interface tutorial. In other words, if you follow the illustrated tutorials you found online, the screenshots show the new interface but you're on an old machine, and the menus don't match and you can't find them. It's not just a matter of eye contact—it's that the menus of the two versions don't even match each other.

one more thing to be clear upfront: you can't manually switch between the two interfaces; what they look like depends on the model and firmware version. Some older models upgrade their firmware to the latest version, and the interface will be updated accordingly. Before upgrading, remember to check the hardware version. Flashing packages between V1 and V3 can cause problems. I've written a detailed firmware upgrade guide on this .

Moves Two or Three to recognize which interface the machine in your hand is

don't need to remember the model year and year; just look three times in the backend and you'll be able to tell it out. At this login step, both sides have the same door: melogin.cn, or the IP printed on the sticker on the back. If you can't open it, first go through the login troubleshooting . 90% of the time it's stuck because the address was misremembered and the person isn't on this network. After entering, look at the three spots below.

especially useful for third-hand old machines. For older models like MAC1200R, the same name comes in two batches: 100GB and Gigabit versions. The second-hand pages look exactly the same, but the price difference is 20 yuan. Before buying, you must check the back case stickers for a glance. The complete method for identifying stickers is written in the on how to identify models.

3. The Wireless Matter: Name, Dual Band, Hidden, Visitor

the wireless features of the old interface are all concentrated in the "Wireless Settings" menu on the left: Basic Settings This page includes WiFi name, password, channel, and even the hidden signal toggle on this page. Use the checkbox; The encryption method is switched to the "Wireless Security" submenu. Each family has its own address, easy to recognize.

new interface has broken them down and reorganized: in the top right corner, "Advanced Settings" → "Wireless Settings." Dual-band machines are further divided into two sets: Wireless 2.4G and 5G Wireless Settings, each managing its own "Master Network." I want to split two bands into two different names. The switch to turn off is not called dual-band integration, but 'multi-band integration.' It's on Master Network's page. My cousin's 500 Mbps broadband is stuck to 2.4G and only runs 180 Mbps, but after turning it off, it immediately returns to 480 ( to disassemble dual-band full record ). Hiding WiFi is the same idea. In the new interface, the switch is called "SSID Broadcast." It's normal not to find the word "hidden," but the tutorial that simply copies the old interface terminology is even harder to find ( the hidden signal ). If you set up a guest isolation net, go to the wireless settings → guest network, open one every two steps, and even if relatives connect, they can't access your NAS ( guest network settings ).

4. Internet Access and Segments: WAN port, DNS, IPv6

the old interface, change the internet method, select 'Network Parameters → WAN Port Settings', and enter your broadband account and password here; Change the router's own LAN port IP in the "Network Parameters→ LAN Port Settings." If you have a collision with the optical modem subnet, this is the place to move. After making changes, remember to check the DHCP pool ( the entire process of changing the LAN port IP ).

new interface also goes from "Advanced Settings → Network Parameters." WAN port settings remain in the old position, but the most deeply hidden feature is manual DNS—it doesn't set the main page on the WAN port but requires clicking another layer called "WAN Port Advanced Parameters." I also went the wrong way on my first trip and wasted three rounds ( Mercury changed DNS). IPv6 switches are also at the network parameters level; just one switch and one internet access method are needed ( Mercury turns on IPv6). Don't keep stubbornly battling old interface machines; most don't even have this feature. It's true that they don't exist, not that you haven't found it.

5. Managing Equipment: Riding the internet, speed limits, parental control

checking who is freeloading the web, the biggest difference is place: the new interface homepage has a "Connected Devices" card, making device management more comprehensive; The device list for older machines is hidden somewhere you wouldn't expect—the 'DHCP server → client list.' The first time I searched, I clicked the menu on the left from start to finish, but finally found it hanging under DHCP ( the whole process of checking and mooching the web).

Limit device speed: In the new interface, click the device name in Device Management, and fill in the numbers directly in the downstream and uplink boxes; The old interface feature is called "IP bandwidth control," which sets rules by IP range. The pre-installed device still needs to bind static IPs; otherwise, once DHCP drifts the rules, it will be useless ( speed limit reference numbers ). Managing children's internet time is in the new interface under "Internet Control → Parental Control." It's set up in three steps, but there's a big pitfall: all devices outside the parent's list are managed by the child, and the home cameras and speakers will all be blacked out at night ( parental control to get caught in the pitfall).

6. Common functions for aligning a table; if you can't find them, follow this order

port mapping is the biggest difference between the two names: the old interface was called 'Forwarding Rules→ Virtual Server, while the new interface moved to 'Advanced Settings→ Advanced User →Virtual Server.' Not a single character of the name matched. My colleague followed the new interface tutorial to find 'Advanced User' on an old machine and spent half an hour searching ( Five-Step Port Mapping ). Factory Reset and Configuration Backup: The new interface is under "Device Management→ Restore Factory Settings. Backup and import are on the same page. Export the configuration files before resetting to save the whole family from a reconfiguration ( three things to save before factory reboot); These two old interfaces are now under the 'System Tools' menu.

Mercury WiFi App adds another division of labor: it can do daily tasks like checking online devices, changing WiFi name and password, and turning guest networks on and off; Parental control, port mapping, manual DNS—these advanced operations can't be found in the app, so just obediently return to the webpage backend ( remote management ).

really can't find the menu, follow this order: Step one, first recognize the interface, check whether the homepage is a card or a vertical left column, don't rush to click; Step two: follow the table above and search for the name in the corresponding column. Don't use new names to search for tutorials on old machines, and vice versa. Step 3: Take a screenshot of the tutorial: First, check the homepage appearance. If it doesn't match what you have, switch to another post—don't force the steps together. Step 4: On an old machine, look for IPv6 or app binding and other new features to abandon immediately. If hardware and firmware don't support them, try on a new machine. The two interfaces are just the menus that look different; the rules are the same: Mercury doesn't have a default management password—if you forget, you have to restore the factory. Before you start, copy down your broadband account and WiFi password—these actions are the same for both.
