How to turn off the router indicator light that is too bright? I checked through five backend stores, but only two switched it on; the Ethernet port light could only be installed

router had been on my bedside table for two years, and this summer I finally couldn't take it anymore. At three in the morning, one blue light stayed on, four network port lights flashed wildly along with the download progress, and even the eye mask couldn't block the leaking light. The moment I lifted the blindfold, I made up my mind: this light must be turned off today. So I checked the backend of five routers of different brands at home and at my relative's house, and the conclusion was a bit unexpected—only two of the five properly provided switches; the others were either hidden deep or had none at all.

first identify the lights on the panel—not every one can be turned off

recognize the lamp before you start. The lights on the home router panel are divided into two shifts: one is the system light , which is the power, 2.4G, 5G, and internet lights. These are controlled by the firmware, and the software can turn them off; The other is the Ethernet port light , with a small green dot embedded in the RJ45 port. When plugged in, the data flashes along with the data. This light is directly driven by the switch chip, so the router system can't control it at all—which is why some brands later have 'lights flashing even when the lights are off'—not because they weren't turned off completely, but because they were turned off, not the same ones.

how bright it is, let me give you a number. I installed an illuminance meter app on my phone and tested it: the bedroom's nighttime background was 0.3 lux, the router contributed 8 lux from 30 centimeters away, and when downloading and running, the port light flashed to 15 lux. What does 15 lux mean? It's basically the brightness of the hallway night light, and it even flashes. People are much more sensitive to flickering light than to constant light, which is the real reason they can't sleep.

so turning off the lights is a two-step process: first, use software to turn off the system lights, then physically handle the network port lights. Below is a brand breakdown.

Huawei and Xiaomi: There really is a switch in the app, these two are the most worry-free

Huawei and Honor routers, turning off the lights is the simplest solution. Smart Life App, open it, go to your router device, go to 'View More', scroll to the 'Indicator Light' switch, and turn it off with one click. The Honor device uses the same app, with exactly the same path. The official explanation is that even after restarting the router, this setting won't be lost. My mom's Huawei AX3 was turned off last year and still hasn't lit up by itself. During the New Year, I went through broadband reboots, fiber modem battery swapping, and the router restarted several times, but the light never came back.

Xiaomi and Redmi go the Mi App, look for 'Panel Indicator Light' on the router's device page to turn off both the system light and the AIoT light. Which light means and what it means when it flashes. The previous article on light language explained quite thoroughly. If you don't understand the light, go ahead and catch up Xiaomi router indicator light color meaning .

the common limitation of these two brands: the network port light does not use this switch tube. Even if all the system lights are off, the network port light still flashes along with the transmission, so applying blackout stickers for the bedroom machine is probably not a neglect.

ASUS: Changed the WPS key on the back to a light off button, allowing you to set it up in one step for long-term use

ASUS website backend doesn't have a direct "turn off LED" option, but it offers a more elegant solution: change the WPS physical button on the back to a lights-off .

your browser and go to the backend, in System Management and System Settings, there is an option called "WPS Button Behavior." By default, it triggers WPS pairing. Change it to "On/Off LED," then click "App Settings to save." Then the button on the back turns into a light off switch: when the light is on, press once to turn it off; when the light is off, press once to turn it on. After modifying my RT-AX86U, pressing a button before bed is much faster than pulling out my phone to open an app.

two additions. First, some models like the RT-AX82U have a dedicated LED power button on the side, so there's no need to adjust it; Second, after the change, the WPS pairing feature disappears—anyway, I've always recommended turning off WPS because the PIN code method isn't safe. If you understand the principle, check article on whether to disable WPS on routers. It's a win-win situation.

Tenda's biggest frustration: one button for three identities, one wrong button and the whole family loses the internet

many Tenda models have a reuse design: a short press switches to WPS, and after 3 to 10 seconds, the indicator light switches again. If you press it for more than 10 seconds, it returns to factory settings. Three functions are packed into one button, all distinguished by duration.

I turned off the light on my cousin's Tenda in the bedroom, thinking I was skilled at it, pressed it for about 2 seconds before letting go—WiFi was turned off immediately. His robot vacuum, speaker, and camera all went offline in the middle of the night, the Mi Home app showed a gray screen of devices, and the next day his mom thought the router was broken. So Tenda users should honestly press this button for a few seconds in their minds, count to five, then relax.

the backend of the website, some new Tenda models have a "Smart LED Light" option under "Advanced Features," which is quite detailed. It offers both steady-on and timed off-off modes, and can be set to automatically turn off at 10 PM before turning back on in the morning, which is more elegant than physical buttons. On the old model, after searching the background without this feature, all that remains is pressing the body button in a few seconds. If you can't access the backend, first check the Tenda Mercury backend if the backend can't be opened. Don't rush to press reset.

TP and Mercury: Backstage searches but no results, just accept your fate

I searched the

TP-Link home router's web backend twice, inside and out, but there was no LED switch. The AP panel from the other company supports timed lights-off, so don't expect the home model. The old Mercury model also doesn't have it. The new model lets you try your luck in the melogin.cn's "Advanced Settings" and make a profit; if you can't find it, then it's really nothing.

users of these two companies can jump directly to the next section on physics solutions. By the way, the system light has no software switch, and the network port light is attached to the light-blocking machine, so the whole machine goes black at night, which actually gives it a premium feel.

the network port light won't turn off? Three things are more respectable than black tape

Ethernet port light is directly connected to the switch chip at the hardware level; no brand's firmware can turn it off, only physically blocking it. I tried three materials:

First, electrical insulation black tape . Cut into strips about 4mm thick, covering everything thoroughly, with 15 lux straight to zero. The downside is that after a long time, it can leave offset marks when peeled off. You can wipe it off with an alcohol swab, but it's quite difficult to clean the groove on the mesh port.

Second, search for 'indicator light shading sticker' on e-commerce platforms. For just a few yuan, you can get dozens of large sheets—die-cut small round and square sheets. Just tear them off and stick them on—much neater than hand-cut tape. Here's a little trick before posting: let the machine run for a while to download, then keep an eye on which network port lights are most active, prioritize sticking those ports, and the less frequently used port lights are already idle. My current fixed plan is this: one board is enough for the whole family's router and TV standby light.

Third, semi-transparent masking paper . It dims but doesn't go out, and after two layers, you can still faintly see the lights flashing. It's suitable for machines that still have a slight troubleshooting need—after all, the lights are completely blocked, and when the internet is off, you can't see Deng Yu even if you want to. But there is an alternative: if your phone can connect to WiFi and you can access 192.168.1.1, check the status page. Check the logs for disconnection patterns and causes more accurately. I previously used logs to catch a scheduled network outage at midnight, which was more reliable than watching the lights. The idea is in the on how to read router logs . If it reaches the point where the background can't even be opened, then follow the six-step troubleshooting 192.168.1.1.

final piece of advice: if your router is old, noisy, and has lots of lights, instead of sticking them one by one, it's better to move it out of the bedroom. Pay attention to placement the in the article about router placement—both signal and sleep will be saved. For someone like me who nails the nightstand to the edge, I just use the app to turn off the system light, add a blackout sticker, and the mesh port light—just two steps, and I slept the whole night.

the order of hands-on tasks is also laid out: first check the app and background to find the software switch; if you can't find the camera button (make sure to use the multiplex button for a few seconds), use the network port light to physically block it, and after that, remember to leave yourself a way to check the status in the background. The lights are off, but the net can't be blind.
