How do you check who is freeloading on Tenda routers? The network speed control page count shows 8 devices, but my home clearly only has 7

Friday night, I was watching videos on the sofa, stuck into a PPT, the progress bar spinning until I tossed my phone aside. At home, we have Tenda AC10 connected to 300M telecom broadband, which is more than enough for two people. After checking the backend, I found that the 'Speed Control' page had eight devices lying there—my family only had seven, at most: two phones, a laptop, a TV, a smart speaker, a robot vacuum, and a camera. The extra one labeled OPPO-A3 is something I don't recognize at all.

first find the door: tendawifi.com and 192.168.0.1 are the same door

Connect your phone or computer to your own WiFi, enter tendawifi.com in the browser's address bar, and if it doesn't open, switch to 192.168.0.1. Both addresses go to the same backend, so whichever one works. Three details when typing: don't type in the address bar into the search box. My mother-in-law typed it in the search box the first time and found a page of ads; Don't cheaply add HTTPS; old firmware is unacceptable; Distinguish between the letter l and the number 1. If both addresses can't get in, that's another problem: domain hijacking, DNS crash, gateway alteration. I wrote six pitfalls in the article about 192.168.0.1 not being opened, listed accordingly.

forgot your login password, first check the sticker at the bottom of the machine. The old Tenda sticker had a default password, but the new model doesn't have a default password—I set it myself the first time. I really can't remember to read the article about Tengda's initial password . Don't rush to reset—after resetting, you'll have to refill all dialer account passwords.

Where to hide the

device list: Three sets of interfaces for each location

Tengda has changed interfaces several times, but the location of the device list is different, so many people get stuck at the "Where is the list":

my AC10's list is on the "Speed Control" page. This design is counterintuitive—checking how the device ended up on the speed limit page. I spent a long time searching the first time and thought it was in "System Management." List four most useful information for scraping and scraping online: device name, online time, MAC, and real-time speed. That OPPO-A3 was running over 8 Mbps in real time at the time. While others were watching shows at my home, I was watching PPTs at home.

bind the Tenda WiFi App, it's even easier. Even people at the office can browse the list. On the app's homepage, tap 'Router' to access the router, and remotely handle online devices, blocking, and unblocking. I ended up blocking that OPPO during my company lunch break. When I opened the device details, there was a switch to disable internet access, just like in the background. If you haven't bound before, see the Tenda App binding . Note: Android 9 and above requires location permissions, otherwise you won't be able to find the device.

Three

Ways to Recognize People: First, Identify All Your Own Family, Then Catch Strangers

8 units on the list, how do you tell which one is a thief? I followed these three tricks:

first trick is to check the online time. That OPPO-A3 goes online every day at 10 a.m. and off around 9:30 p.m., which doesn't match my daily routine at all—we work during the day, the home camera and vacuum cleaner are on, but the phone isn't there. But the business hours of the nail salon across the street. The online routine of the internet device follows others' schedules, and this is more accurate than anything else.

second trick: inspect the manufacturer. The first six digits of MAC are the manufacturer's identifier segments. If you put the entire MAC into the macvendors.com, you can check its origin, making it obvious whether it's a phone or a TV. But here's a discount now: if your phone has a random MAC enabled, it will show a "random local address," so you can't tell the brand. I explained this thoroughly in the of MAC addresses.

third trick, the elimination method—clumsy but the most reliable. Turn off WiFi one by one on phones and computers in the family, and the list will turn gray one by one. The one that stays lit after turning off is this one—it's all in five minutes. Don't turn off smart speakers and cameras—they're always online, so start with your phone.

By the way, I've also checked the backend for Mercury and Xiaomi, and the terms and paths are different: Mercury's list is in Device Management, and that article is here in ; Xiaomi has a sneaky trick where the Mi Home app pops up new device notifications late at night, written in . If you mix several brands at home, you can check them all out.

handling is divided into two levels: blocking means closing the door, speeding means keeping the door open

confirm it's freeloading, Tengda blocks you in one step: still on the "Speed Control" page, find the device, turn off the "Allow Internet" switch on that line, click confirm, and it will disconnect immediately. The official explanation is that the blocked device can no longer connect to the router's WiFi—this means the device is kicked offline for five minutes and then reconnects again; it closes the door, and even if it enters the correct password, it can't get in.

second option is "More Features" → "MAC Address Filtering." Set the filtering mode to "Blacklist" and enter the device's MAC. Here's an official FAQ pitfall: after filling out the macOS, you must click the "+" on the right side of the input box to make sure it enters the blacklist below, then click OK. The first time I filled it out, I just clicked confirm. That OPPO was lively all night, and only found out the next day it didn't work at all.

don't want to wipe it out—like a cousin who stayed for two weeks online—speed limits are more suitable than blocking, leaving him 20 Mbps of downlink, enough for video streaming, and no one else gets blocked. Tenda's speed limits are set on the same page. I wrote about the differences between the old and new interfaces in the Tenda speed limit article. The old model is based on IP range, and the new model is based on device access—don't mix them up.

accidentally pull your own people, or block them and still stay online

If you accidentally block your own family member

, unblock them at these two points: on the "Speed Control" page, go to the device list and go to the blacklist device, click "Unrestrict" on the right, and confirm; Or go back to 'MAC Address Filtering' and click the '-' on the right side of that device to move out. I once mistook the smart speaker for a thief in the middle of the night, and the next day, no matter how much I called it, it didn't respond. After a long time of digging, I realized it was my doing.

after blocking, the device reappears in the list the next day. There are three possible reasons: first, the random MAC has changed its identity. If the phone has random MAC enabled, forgetting to reconnect the network once will change the address, you blocked its old address, so you need to add the new one; Second, dual-frequency two records: one for 2.4G and one for 5G. You only pull one, while the other is still alive; Third, it doesn't connect to your router at all—it could be the optical modem's own WiFi or the neighboring WiFi with the same name. The official FAQ also reminds you to check the IP and MAC displayed on the screen to match your actual device before proceeding. There's an even more annoying situation: if you block one device, a new one comes in a couple of days, which means the password has already spread among others. At this point, don't try to pull them one by one—just change the password in one go.

Prevent recurrence: Changing your password once is worse than blocking ten people

Tenda's official documentation about the blacklist feature, it immediately exposed the root of the internet access: apps like Master Key automatically share the WiFi passwords of phones connected to the internet. My OPPO probably got in like this—I don't know which relative visiting had a key on their phone, connected to my network, and the password leaked out.

so after blocking, there are two things you must do. First, change your WiFi password to a 16-character or more mixed alphanumeric password. The mobile app can change it in two minutes. The whole process is in Tenda's password change article. After changing it, your family just needs to reconnect. Second, tell your family to remove the master key, at least turn off the auto-sharing hotspot connected to the hotspot. Otherwise, just after you make changes, the key will be shared with you again, and all your efforts will be wasted.

follow this sequence, counting the device to changing the password, and finish within half an hour. Preventing internet access once is enough—passwords don't leak, you don't need to open the backend for half a year, that's better than anything.
