How to check who is freeloading on a Mercury router? Browsing the device list in 192.168.0.1, I found two unfamiliar phones
at 11 PM, I watched a show, but the progress bar was stuck like a slideshow. On 300MHz broadband, only 70MB remained. My first reaction wasn't to unplug the router, but to grab my phone and go backend—there were 9 permanent devices at home, 11 of which were listed, and two more appeared: one HUAWEI, one for some unknown "android-7f", online for one afternoon or a week.
was just being taken advantage of. Mercury's backend isn't hard to resolve; the challenge is recognizing people: kick the wrong one, and their own surveillance will be offline for you to see. This article records the entire process of that night, from backstage to kicking people out and cleaning up afterwards—just follow the instructions.
go to the backend and find the list: melogin.cn login, check the device management section.
connect your phone to Mercury's WiFi (if you really can't connect, use a network cable). Enter melogin.cn or 192.168.0.1 in the browser's address bar to enter the same management page. Either route is fine. The domain code is that it only resolves within the Mercury router's own network. If you switch to traffic and open it, it will definitely fail. This is normal, not broken.
Next, enter the management password. This password is set by you yourself when setting up the router for the first time, and it's a completely different thing from the WiFi password. If you can't remember, don't try blindly; guessing is impossible—forgot you have to reset and start over. I've written about the entire process of resetting and redialing after resetting, in the on resetting router. If you can't open the login page at all, that's another issue. Most likely it's stuck with domain resolution or HTTPS hijacking. Just follow the of the melogin.cn article that can't be opened. He had a second-hand machine with no password at all, so let's first look at the rules the initial password for Mercury.
logging in is the key. My D191G has a new interface. After logging in, the homepage immediately shows a list of connected devices. Each device has a line: device name, MAC address, assigned IP, whether it's connected to 2.4G, 5G, or wired, followed by real-time upload and download speeds. If you find the homepage too small, go to the 'Device Management' page to see the full content, it's the same thing.
interface looks different, don't worry—Mercury's firmware has been updated over the past two years. If you can't find 'Device Management,' go to 'Common Settings → Connect Devices'; Even the oldest machines (MAC1200R the batch) have their lists hidden in the 'DHCP Server → Client List', which is a bit rustic, but you can still see who is online on the network.
you can watch even when you're not at home: install a Mercury router app, enter the management password, and swipe in real time in 'Connect Devices'—you can browse your home list even while you're at the office. After a week-long business trip, I wanted to check if there were any unfamiliar devices at home, and that's exactly what I needed.
three ways to recognize people: don't treat your own equipment like a thief
Out of about ten devices on the list, which one is the thief? I have three tricks, ranked by convenience:
first trick is to match the name and time. device name is the biggest distraction—the name displayed on Mercury is half the phone model and half garbled, and something like "android-7f" is impossible to tell who it is. Don't worry about the name—look at "online duration" and "connection time": your device's online routine matches your lifestyle (disconnects in the morning, comes back online at night). People who use the internet often do it all day or stay active during times when no one is working. The HUAWEI I caught was exactly like this—it was online for 7 days without interruption, while no one in my family used a Huawei phone at all.
second trick: check the top six MAC vendors. the first six digits of each device's MAC address represent the manufacturer, search for "MAC OUI lookup"; if the manufacturer matches the device name, it is your own brand. On the WiFi detail page, you can see your MAC and check each one carefully. If it doesn't match, you're the suspect.
third trick: the elimination method. turn off the WiFi of every device at home: turn off WiFi on your phone, unplug the cable from your TV—anyone who doesn't disappear from the list is considered an outsider. This trick is the dumbest but also the most accurate, especially when all the device names at home are a bunch of garbled characters. Cameras and robot vacuums that are hard to turn off are left for last. Kicking the wrong camera can push offline cameras and blow up your phone.
Mercury's 'ban' is to block, not just to kick down. Once you identify a thief
click on the device line and there's a button to disable . Clicking it causes the device to immediately disconnect from the internet, and even if the router is restarted, it won't get in—that's the blacklist. Mercury Tube is called disabled, meaning the same thing.
But what many people think about the "offline" (disconnect once and then reconnect) does not have an independent button in the Mercury backend. If you want to simply disconnect it from the blacklist, the simple solution is to restart the router—but those who use the internet store your password, so reconnecting only takes a few seconds. So my advice is: don't hold back—just disable it altogether.
you kicked the wrong one, it's easy to get it back: in device management, open the "Disabled" list, click "Allow internet access" on that device, and it will revive. So even if you can't figure out the earlier recognition step, if you really make a mistake, there's still a way to regret it.
a quick reminder: if you enter the Tianyi Gateway backend and can't find this feature, that's a different approach. Tianyi Gateway to see the device kick people I've written about it separately. The menu path is completely different, so don't keep stubbornly stubbornly stuck in the same backend.
Random MAC Pitfall: After kicking the second day, another 'new device' appears
After kicking, another unfamiliar device appears in the list, with a different name and MAC than yesterday's—don't rush to doubt your life, it's probably still the same phone. iPhones and recent Android phones have "private addresses" (random MACs) enabled by default, generating a fake MAC for every WiFi connection, and some systems even replace them regularly. You banned their old vest, but they still knocked on the door after changing their disguise.
the cure for this pitfall isn't to keep kicking, but to change the WiFi password . The premise of freeloading is that it stores your password. Once you change the password, it can't even connect, and random MACs are out of reach. The steps to change the password are in the article about changing the Mercury WiFi password on phone—it takes five minutes. After the update, I casually turned off WPS. The 8-digit PIN code on that thing was another broken path.
random MAC has a downside: if you disable a family member's phone, it automatically reconnects with a new MAC. You think you're kicking a thief, but you're actually kicking your own child. So ban the first three skills to recognize people—don't skip a single step.
lazy person cure: Owner Network Protection Whitelist
If your home only has a few devices for years, there's a one-time toggle: advanced settings→ internet controls→ Owner Network Protection . Add your device's MAC to the whitelist; all devices outside the list can connect to WiFi but cannot access the internet. Even if the internet smuggler's password was correct, it was useless—it was just cut off at the door.
the cost is that guests must be allowed through manually. My family has visitors only once a month. I found it troublesome, so I didn't open the whitelist. Instead, I changed my password and regularly checked the device list. If you often have guests, this trick might annoy you. Weigh it yourself.
also has a mindset of "if you don't kick, you can't stop it, making internet users so slow they start questioning life": in device management, setting a 512Kbps limit for unfamiliar devices makes the video unwatchable—the operation path is in the Mercury speed limit section .
wrap up with a complete sequence
handling of those who got caught off guard, and stick to this order to avoid detours:
| sequence | actions | key points |
| 1 | go to the backend to check the device list | melogin.cn or 192.168.0.1, on the Device Management page |
| 2 | the Three Ways to Identify Person | Check the Time→ Check MAC Manufacturer→ Eliminate Method, and go through all of them |
| 3 | disable unfamiliar devices | kick the wrong one, you can recover it from the disabled list |
| 4 | change WiFi password | Completely cure random MAC swaps, close WPS |
| 5 | and check the | list after a week to stabilize your device count |
if your network has other issues besides using the internet, the universal three-layer protection approach is explained more thoroughly in the article on anti- internet. Watch along with it.
