Why Sys-Admins Are Disabling The Lights on WiFi Access Points (networkworld.com)
More than a dozen IT professionals said they've disabled the LEDs on wireless access points, according to a Network World article shared by Slashdot reader alphadogg:
Some users don't want a beacon shining in their eyes as they try to get to sleep and others worry about the health effects of a blue light glowing all night. Some even resort to unplugging the gear when they're not using it.... "It seems when you are sick and laying in a hospital bed and have trouble sleeping, the single LED shining in your eyes is an issue," [says the wireless network staff specialist for Penn State College of Medicine]. "I get it and understand it..."
Network pros say they have begun asking vendors such as Cisco if they can provide an easier way to dim, rather than turn off the lights on the access points entirely, via wireless controllers. And some would like to see more granular control, such that the power light could be left on to comfort end users that the device is working, but blinking lights could be turned off or dimmed to avoid bothering them.
End users have tried "all sorts of makeshift fixes -- from Post-it notes to bandages to condom wrappers," but one network architect complains that when they disable the LEDs altogether, "I invariably get a ticket (or more) that the access point is offline and wireless is broken because there are no lights on..." On the plus side, when they then re-enable the LED lghts, "magically the wireless performance and coverage is perfect!"

Why can't we get a strip ok old school lcd like in the digital watch of the 1980.
It can show the info without the light.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
This is newsworthy? Slashdot continues to decline with each transition to a new owner. It's literally become a clickbait site.
I just use a black marker to darken the surface. You can essentially black them out or leave a little light passing through.
So, it has come to this. An article on Slashdot about covering up blinking lights.
one network architect complains that when they disable the LEDs altogether, "I invariably get a ticket (or more) that the access point is offline and wireless is broken because there are no lights on..."
Then cover them with black masking tape. Voila, no lights. Plus, everyone can see why there are no lights, so they won't be psychologically fooled into thinking the thing isn't working. And if there really is a problem, they can peel back the tape and have a look.
Bloody hell...
systemd is Roko's Basilisk.
At home I used to disable LEDs on router/access point. The reason was: At night they made it harder to fall asleep.
Now a days, router is away from my sleeping room, so I have no reason to disable LEDs.
At work I would disable LEDs on network equipment only if I would be sitting directly in front of it for prolonged time. Blinking lights are distractive.
Have a look at Turris Omnia - the LEDs are dimmable in 8 steps, the last one being completely off.
They should add light sensor and dim based on that. iPhone display does that btw.
At home, I turn off all the beeping on the UPS. On some, I had to remove the speaker. If I'm home, I know the power is out. I don't need a beep to tell me. If I'm away, my UPS shutdown the systems and it was logged that it went down.
Don't want LEDs shining on you in the night? Turn the router so the LEDs aren't facing you.
LEDs too bright? Use white tape/masking tape over the LED to reduce and diffuse the light.
Don't want LEDs at all? Use duct tape.
Seriously it's not rocket surgery guys...
When you are already in an uncomfortable state, smaller irritants get to you more easily.
Also, different people are different. For some people it is a much bigger irritant than for you.
Once when I was in a hospital, I was alone with a machine that was ticking... and which now and then changed the rate it was ticking. That thing drove me insane. (figuratively)

I've been reading slashdot for years and I've never seen a story about blinking lights and not much else.

You should try a UK NHS hospital. You'd be lucky if you got a room alone - oh wait, you wouldn't, because you do get such a room when they think you are about to die. My experience is that they are like floodlit madhouses, 27/7.
Nope, didn't read the article. The summary itself is all over the place. What are they even talking about? Blue light keeping admins who take naps in router closets from being able to sleep? Or millennials complaining because the are living in their moms basements and being kept awake because the router is still down there? Who the hell walks around the office looking for blue lights shining through to see if wifi is working? Who are these people?
Actually, it IS a big deal. Sleep is important to a patient's recovery, and a lack of good sleep can slow healing.
Patients in a hospital are constantly being disturbed at night due to vital signs checks, administration of medication, pain medication wearing off, etc. Sometimes the disturbance is not even for the patient but for the other patient in the same semi-private room. Falling asleep is difficult enough; getting back to sleep can be worse. Lots of strongly glowing and flashing LEDs and other indicators can make it darn near impossible, especially if the patient is already in pain and having to lie in an uncomfortable position.
Imagine you were trying to sleep in the middle of Times Square at night, with all of the lights and noise. That's what it's like. As IT professionals we can at least cut down on the lights and beeps, even if we can't do anything about the other disturbances.
My last tower's power light was just insane. I used to put multiple layers of tape over it as one layer of opaque tape was not nearly enough. Even during the day, if pointed in your general direction it was painful, and even when pointed away at night it would raise the ambient light level of the room enough to be annoying to sleep with. You could read by it, it must of been equivalent to a ~5 watt light bulb of something in that category. Probably something like 20 times brighter than any other indicator light I have seen before or since.
Troll is not a replacement for I disagree.

Or they just think you might have norovirus.

But if you ask nicely they'll usually give you some sleeping pills...
Actually, after personal experience of both, I've come round to firmly believing in shared wards. The single room wasn't because of imminent check-out (unless there was something they weren't telling me) - just the temporary luck of the draw. Single rooms give you altogether too much time to feel sorry for yourself, whereas on an open ward you have endless distractions and there is almost guaranteed to be someone who has it far worse than you, to put your woes into perspective (in one case, I even got to press the emergency buzzer for a nurse who collapsed on the job). Worse case, if you really are the worse-off person in the room, then you can enjoy your self-pity with the warm glow of vindication.
Turning off equipment because the lights are annoying you is probably a bad idea, though.
In a survey of 100 programmers, 111111 thought that duck-typing was a good idea.
The problem is not limited to access points. Power strips, monitors, speakers, keyboards, mice — everything has a LED.
Some devices have options to turn off the LED when working, but insist on blinking said LED when in standby. Good luck turning your monitor to face the wall so that its blinking LED doesn’t disturb your sleep.
Does anybody make a something like Scotch tape except that instead of being transparent its got about a 90% tint to it?
Of course there are about a 1001 DIY equivalents, from electrical tape to permanent (or even paint-type) markers, but often the DIY solutions have drawbacks that make the lights either impossible to see or require some other intervention (getting a ladder to remove the tape..).
Tinting film for cars works, more or less, but it comes on rolls that are impractically large. Something the size of a scotch tape dispenser would be better.
I know they would cost more and take more room, but what about simple electro-mechanical indicators? For something to replace an multi-color/flashing LED you could get by with a simple rotating coloured disc. You can easily display four different states by having each disc quadrant a different colour. Rotate 90 degrees and you're displaying a new status colour.
For a simple on/off indicator a tiny electromagnet could push/pull a rectangle with two different states on each side.
The alternative to these complex and possibly expensive solutions? First of all use a normal LED, indicators aren't flashlights. Second, put a frosted plastic in front of it to diffuse the light and make it less blinding. Third, blue LEDs were cool when they were introduced, now they're just annoying. Blue is blinding, red is agressive. Why not switch back to green LEDs?
I have my router in my basement. I've covered the LEDs with black electrical tape because otherwise, after a few months, I have spiders and all sorts of other little bugs hanging around and trying to get into my router. I'm not sure if the bugs caused any real performance issues, but it's nice to not have to clean the thing for every hard reset.

How idiotic does a person have to be to not think of covering the leds up with masking tape? People still wouldn't see the lights, but they'd see the tape, and realize that the tape is covering them up and not that they are not even lit.
File under 'M' for 'Manic ranting'
I mean, it's bad enough that the stereotype of techies is we're all fat, slovenly weenies who can't pick up a thick book (let alone a lady). But when we're so freaking lazy we can't even turn the AP to face AWAY from us? Well - we just confirmed the stereotype...
Browsing at +1 - no ACs, I ignore their posts. So refreshing!
If they were that concerned about the led's and wanted to do something about them, assuming the device was no longer under warranty, why didn't they just trace the node that the led is connected to and simply bypass the smt resistor by removing it, taking a small guage solid wire, soldering it to the resistor and installing a 5kohm potentiometer that they could mount to a circuit board that can be fastened down using one or two screws, washers and nuts to the casing, with the pot knob exposed outward so that they can install a pot knob cover. All the job needs is a esd safe soldering station, a small hand drill or electric drill, and access to digikey.
Try that in a hospital and Bioengineering (or whatever they call the folks that are tasked with fixing things with batteries and / or power cords) will be on you like a ton of bricks. No mods! No kinks! No tape! You leave it ** alone ** or something Very Bad could possibly happen and we don't want that, do we?
Hell, I can give our guys the willies by walking around with some zip ties.
Faster! Faster! Faster would be better!
More than a Dozen sys-admins (we used to call them computer operators in the 80's) have put black electrical tape over some LEDs.
Definitely worthy of an article on Slashdot.
We should discuss the relative merits of different varieties of black electrical tape. It's called 'bush league' in Horowitz & Hill and I agree. But that's topic drift, and we mustn't have that, because this is an IMPORTANT and interesting discussion of sys-admins (we used to call them computer operators) covering up the LED indicators on equipment.
I love blinking leds! I want more of it! I want a blinking led for connected users, one of it for transmission errors, one it for internet latency, and more! Nothing is more cool and nerdy than a row of blinking leds :)
You must have gone totally orgasmicwhen the first Alien movie came out.
Faster! Faster! Faster would be better!
Oh, cut the bleeding heart crap, will ya? We've all got our switches, lights, and knobs to deal with, Striker. I mean, down here there are literally hundreds and thousands of blinking, beeping, and flashing lights, blinking and beeping and flashing - they're *flashing* and they're *beeping*. I can't stand it anymore! They're *blinking* and *beeping* and *flashing*! Why doesn't somebody pull the plug!
As both a physician who has worked for years in hospitals, as well as a patient who has spent MONTHS in intensive care, and months on a regular ward because I've been really sick and close to death several times myself (was actually dead once for a couple minutes), I will re-iterate my statement. If an LED is all you can complain about, you've not been in hospital long enough. Your points are valid but irrelevant. A LED pales in comparison to - staff talking loudly, carts rattling down the hallway, other patients (or their family) making noise, blood pressure cuffs inflating every 10-15 mins or so even when no longer necessary, monitors starting to beep if you change position and happen to pinch your IV line or decrease the blood flow to the finger your pulse oximeter is attached to, phlebotomists coming at all hours to draw blood, nursing staff pausing outside your door or by your bed handing off to the next shift, doctors doing the same, etc etc etc. You can't sleep at a hospital, period. I really don't notice the LED at all. Every little bit helps, but don't think you're saving the world if you eliminate a LED.
Seven puppies were harmed during the making of this post.
(in one case, I even got to press the emergency buzzer for a nurse who collapsed on the job).
So what you're saying is that their skimping on rooms for you saved a nurse who could have been killed by their skimping on nurses for you.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
I have one in my house. All of my UPSs, routers, TV antenna amplifiers, VoIP interfaces, etc. sit inside the closet, merrily blinking away. If something goes wrong, I check the lights. Otherwise I don't care.
Have gnu, will travel.
I never really minded the red LEDs of the past, but now some idiot decided that was old, and new is white or blue, both of which are horrible in the dark. Blue is especially awful, and apparently bad for sleep.
Wife has a TV box for the TV in the bedroom, and it has a white and a blue LED on the front for good measure. I throw socks and stuff over it every night before bed.
At work, we are in a dark room a lot, and the horrible blue LEDs on the computers there seem like lasers shining in my eyes. I used a label maker (printed BLUE SUCKS) and stuck it over them. Can see enough light through to determine status, but not be blinded.
I like to watch movies on my home theater setup with the lights out. However...
* The TV has a bright blue (which can be somewhat dimmed to not quite as bright blue),
* Yamaha AMP (tons of lights here),
* mac mini has a LED on the front...
* PDU (not a powerstrip)
Only solution I've found so far is black electrical tape or coloring in all the LEDs with a sharpie..
Why does everything need to have these ultra bright lights? We're not trying to light up a baseball stadium here.

“He’s not deformed, he’s just drunk!”
I'm astonished, after all the years, they still don't understand that we don't want bright LEDs on things.
I've never understood why the LEDs can't be low intensity -- just enough so that you can see if they're on or not.
Instead, at least 50% of all the LEDs on the stuff I own are far too bright.
Usually if companies refuse to give us what we want, there is some profit motive behind it. Is that what's going on here?
White tape pretty much blocks the intensity, but still allows the color to be visible.
I just put a piece of electrical tape over unwanted LEDs.
It's cheap, effective, and totally reversible.

Painter's tape is only easy to detach if you remove it within the time limit of its adhesive (painters tape comes in varying colors to denote the length of time it can safely stay on a surface and still be cleanly removed.) Let that stuff sit on something for a month and good luck getting it to come off cleanly and without damaging powder coating or faux plating on plastic.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
My 10 month old son is recovering from a bone marrow transplant. We LIVE in the hospital. We were in a room recently that had a wireless repeater with a bright blue LED. Nothing contributes more to a less sleepful night for a baby (and a parent who sleeps in the room with him) than that single point of annoying light on the ceiling. Seems to me an old school fuse type device that trips when the access point loses power or signal would make more sense than those stupid LED lights.
Electrical tape is cheaper, lasts longer, and is thicker.
Aluminum tape is also far more effective and just as cheap. A hundred dims for 6 bucks versus being able to punch out THOUSANDS at the same price from a roll of opaque tape.

I expected yet another one of those articles that tell us that hackers can spy on us by studying the blinking lights around our houses. They can tell when our shaver is fully charged or when the flickering neon light in our power strip is about to pass on. They can tunnel in to the heart of our system software and plant worms that cause even more blinking until they drive us insane. Those hackers are shameful with their evil intentions.
...omphaloskepsis often...
This is easy - I just don't keep anything with 24x7 lights in my bedroom. When I did, 1 cent worth of electrical tape darkened the room perfectly. If you are an IT pro and worried about losing sleep due to these lights, you are pretty crumby at your job if you have to sleep with the servers or routers.
This is a hacked account, for which the owner can not be held responsible.
Blue LEDs are disgusting and should all be replaced with old school green LEDs
I use a hardware solution. Whenever I want to turn off an LED I put electrical tape over it.
Yeah, as a story, not a lot of meat here. But I do have to say my home cable modem/router as five lights, three of them blue. The blue ones are bright as hell, and one of those blinks on activity (which is all the time with all the computers in my house). It creates sufficient light to see across the room relatively clearly. Fortunately I don't have it in my bedroom, but I imagine many people really do have that problem. It would be nice to have them at least not as bright. I see no reason for being so "loud".
.....just use a little tap over the light...done and done. Though for me I do not mind it
It's opaque enough to block most of the light, but transparent enough that you can still see the light if you need. And it comes off a lot easier than marker.
It pretty much turns these LED lights from something which lights up your room, to a slight glow on the panel.
Contrary to some posters, this is a classic case of bad, likely unintended, user experience. No product manager said ' let's change the blue lights to something else as we' ll sell more of em.
Likely the same mindset that ended up with cops blue light bars blinding passing vehicles.
I can bet that product managers are asking how hard it'll be to change them out. And will end up changing nothing.
Cited totally out of context. The problem there is the color temperature of your whole screen, which stimulates your brain. This means bluish colors on a large screen (monitor, tablet, phone), not a single tiny bright blue light.
And i solve the led problem mostly with some duct tape.
If these were replaced with IR LEDs, you wouldn't see them normally, but you could take a look with a smartphone camera and see them if necessary.

I wish fire alarms would put an LED on or flash in some distinctive fast pattern when they are going through their "last gasp" series of chirps. I've had enough of being woken in the early hours to try and find which of them is chirping once per minute.

Please provide the raw data used.
Change is certain; progress is not obligatory.
To manufacturers: Just put a flap labelled "open for diagnostics" on top of the indicators.
People who want it, will leave the flap open; those that don't, will leave it closed.

On the other hand I have an access point in a hallway. I originally had a night light as well for my kids. I quickly realized the AP's blinky blue LED's were brighter than the old incandescent night light was.

Simple solution: Gaffer's Tape

Wow. Now I know what to do with the wrapper after I put the condom on the machine so it won't get a virus.

Damn, I did not know that - all I've noticed is the blue. Thx for the info.
Eight in a ward does not sound like fun - in the US (in my experience, both as patient and visitor), two to a room is quite common, with nicer hospitals having private rooms. I had neck surgery about a month ago under MediCal (California's low income health plan) at a teaching hospital; I was quite surprised to get a private room for two days of recovery.
I wonder if that is a trend now; perhaps in order to reduce cross infections.
The LED's on my router have various modes, but the default is that they're off unless I trigger a proximity sensor by waving my hand over the device. Works good.
I have a product from Amped Wireless (extender) that has blinkenlights on it, but has something that sort of confounded me for a few minutes because I'd never seen it before. They have two push-button toggle switches on the rear. One is power (derp), and the other is lights. Turn light switch off and it has no lights at all.
I mention this only because I *LOVE* blinkenlights to indicate the exact status and current activity of a device. For years it's pissed me off that the old 10mbps hubs and switches had lights that were so short in duration per packet that you could literally get an idea of the traffic level of different ports just by looking at it from afar. Then came 100. They started to introduce a delay between blinks. If 200 packets come through in a second, the light only blinks about 3-10 times in that second, depending on hardware. Wireless is worse - it always blinks for no apparent reason (beacons aside). Traffic is hard to discriminate if it's not heavy.
I want a device that has 3/sec, it looks like the ports are in constant use. If there is gigabit traffic going over the port, it looks exactly the same. Fairly useless other than indicating that the network is connected and shit's happening. Can't debug much with that. Home equipment is worse. The cost of LEDs is so low today, who cares? Have there be a separate light for connected, 10mbps, 100mpbs, gigabit, full or half duplex, and activity. Power. CPU activity (routers). Wireless packets. Distinguishing between ARP/reg broadcasts and regular TCP traffic is a whole different thing; I digress.
Why not have it off if everything is working and only on or blinking when something is broken?

Actually, it IS a big deal. Sleep is important to a patient's recovery, and a lack of good sleep can slow healing.
Patients in a hospital are constantly being disturbed at night due to vital signs checks, administration of medication, pain medication wearing off, etc. Sometimes the disturbance is not even for the patient but for the other patient in the same semi-private room.
When I complained that the noise from the IV pump was keeping me awake, the nurse apologized and said, "but hospitals are not a place for resting."
