You’ll get faster download, but your upload speeds drop off a cliff
Use another fan to make the wifi circular, then your upload speeds shouldnt be hindered
Genius. Where’s your GoFundMe?
If you make a series of tubes, you can route from the router and reroute back to the router, creating an information highway through, what we call in comp science, a “loop”. Depending on which side you install the turbo, you can replicate the same tech your ISP charges extra for in “speed boost”. If you go bi-turbo—one in inbound and one in the outbound tubes of the loop—you can generate effectively unlimited speed, where onlyfans used in your inbound and outbound tubes limit based on their RPM. This is why I use RC plane turbines. It’s loud, but I’m streaming YT in 480.
If you put all this in a very small tube that you can easily plug into your router and your PC, then we’ve got real innovation on our hands!
I’m interested to learn more about this. Any article I could read?
I am a computer programmer, this is exactly how it works. Why else do you think electronics have fans in them if not to blow fresh, crisp wifi in and stale, soggy wifi out?

The trick is rewiring the outlet to 240v. More power = more signal.
Hey man, 3db is 3db
Doubling the voltage for a given circuit would result in four times the power, P = V^2 R (*This is wrong, it’s over R, see comment below). So 6db
P=V^2 /R
You’re absolutely right
No no, everyone knows you’re supposed to put a mirror behind it, duh.
Funnily enough this may actually have a positive impact
People used to create tinfoil, tin can or wok based reflectors for WiFi to guide the omnidirectional signal into becoming a directional one.
I think the reflective part of some mirrors is essentially tin foil, so it probably would have a mild boosting effect in the direction of the mirror
Edit: in fact if OP’s fan has a rounded metal cage on it, you could take the front half off and you’ve basically got a WokFi setup there, with added danger
A wire in a Pringles can makes for a fabulous directional can-tenna
Also if it’s close enough, the metal of the fan itself serves as a pretty decent antennae. You can accomplish the same by taping a fork to the box!
It’s the silliest little lifehack yet wrapping a wire around a fork, then wrapping the other end around the router works so well
Modern wifi APs have beamforming algorithms. No reflector required.
I’ve heard about this but not had loads of time to read into how it works and how effective the algorithms are. Do you happen to know about it in depth? I’ve wondered for a while how much efficiency is actually improved by the beamforming and what the limitations are
Like I’ve read about cantennas that fire 802.11g over several hundred meters, which in my understanding is obviously is out of reach for regular WiFi antenna even with beamforming algorithms (or is it? I actually don’t know)
Read up on Yagi antennas.
Essentially you are stacking waves. If you have an array of trasmitters, you can have them send a constructive signal or a destructive signal as a signal “wave” passes them. Using this property, you can change the shape of the wave propagation. Think of it like throwing a stone in a pond, and then throwing in a second or third stone at the exact right moment to combine the ripples, creating a stronger wave in a particular direction depending on when and where you throw the stones.
Man, I’ve always wondered how yagi antennas actually managed to produce a directional beam vs something like a dipole. Your comment has really made it click for me, honestly big thanks! Very clear 5-9
Yep. Now imagine each element on the yagi antenna is its own antenna that can be triggered by a controller, instead of just being one big “dumb” antenna. Now by timing the “firing” of each antenna you can create a directional beam in pretty much any direction.
Yep, and the fan moving in back almost certainly will fuck up beamforming as reflections are fairly important to get the beam to do object avoidance and if your reflective surface is angled and moving quickly…
i have used a long tin can, similar to a pringles can before to steal a neighbour wifi back in the day. this is legit
You’re not wrong. Matter of fact, you’re absolutely right!
Back around 2011, I used a pie pan and USB WiFi dongle to snag the neighbor’s WiFi. My pie pan contraption basically tripled the signal strength, and I never had a single dropout. 👍
But how does the mirror knows what’s behind the paper?!
Will probably make the signal noisy, so I’d avoid this. I would recommend just putting the router in a booster seat, so it’s higher off the ground.
My boss almost saw me looking at this. Close call.
Not Safe Fan Wifi
Can confirm, I’m this guys boss
Get back to making me work!
No because the fan that is boosting the Wi-Fi to you would prevent your computer requests to the Wi-Fi box.
So while it’ll be easier for you to get a YouTube video It would be harder for you to actually type a search. 👍
NSFW?
If you work in IT and want to keep your job, it would be NSFW to say something like this
Reminds me of the time I worked in IT and someone put a department’s wifi access point on top of the microwave. No one fessed up to that one lol
I had a friend complaining that his new computer I built for him was crashing a lot.
So I go there and spend a good bit of time trying to make it crash. Nothing.
Then his girlfriend gets bored and picked up the wireless phone. Bam ! Computer crashed!
It had to happen another time for me to realize it crashed when she was picking up the wireless phone. Turns out the phone base was on top of the computer. Tha cpu was a AMD 950MHz and the phone a 900MHz phone. I have no ideas if the frequency is at fault or the phone base was creating bad interferences somehow but taking the phone base away from the computer finally solved the problem.
That’s so weird
I work in IT and we always say stupid shit like this to people.
yes and you can also leave out a plate of cookies where you want a strong signal so the wifi waves will go there when they’re hungry
Just don’t bring the ones from the third party, I heard they’re bad for the privvy or something.
Don’t be silly!
Wifi is not man, Wifi doesn’t eat cookies
It eats lead. That is why wifi antenna’s have a bit of lead surrounded by copper, so it can lure the wifi with the lead and catch it with the copper. Also why it stops at lead walls since it is like a buffet for them.
Ask ElectroBOOM, he would definitely make a video rectifying it
*bang*OUCH F___ S___ why is there a loose wire?If it has metal blades then it will reflect some of the radio signals, making the transceiver more directional. With how it’s set up in the post, it could potentially be a benefit to devices that face the front of the router and fan, but a disadvantage to devices behind the fan. Same logic with that Facebook trick of putting tin foil or cut up drink cans behind the antennae.
However, most newer and higher end routers use beam forming antenna arrays which are already directional and can automatically focus the signal toward your devices. Having reflectors around those can actually interfere with the antenna array and decrease speeds for all devices.
Beam forming is a bit more complex than just being directional.
It makes the signal stronger in the target location, but the antenna is still very Omni-directional. It’s just using extremely small signal offsets between transmission antennas to optimise the amplitude of the signal in the area of the receiver.
Directional antennas can still very much help, as well as wave guides to push more signal in the desired direction (sacrificing signal in another, potentially undesired or unrequired direction).

It gets really interesting when you get into mimo and multi-user mimo, and the system is transmitting on the same channel to multiple endpoints at once, with different data for each. Shit is crazy.
Next you’re going to tell me having the microwave on slows my WiFi down!
Facebook lmao. That trick was around decades before Facebook.
Alright, so according to Bernoulli’s principle says that moving fluids result in a lower air pressure. Light and all electromagnetic waves are fastest in a vacuum. Lower air pressure is closer to a vacuum. So… Marginally? I have no idea how much but I’m guessing it’s miniscule enough to need special equipment to detect. Not worth it. Plus the fan itself could block the waves. The fields around the wires powering the fans would have an effect as well. All of this is going to be super minor but I think the physical blockage of the fan is going to have more of an effect (but still teeny tiny) than anything.

In order to be unessecary specific:
if it would benefit the waves:
it would only benefit the outgoing waves.
The waves coming back feom clients, transmitting data back to the wifi access point would have to fight against this additional airpressure.
But this is all only hypothetical and i am sure in the real world it would make no difference even if there would be a benefit in theory.
And yes you are correct the electromanetic field of the spinning fan would definitly harm and not improve the signal quality.
It’s simple. We point it away from the router except during large uploads!

The wifi beams come out in all direction. You can help boost the wifi by placing a mirror behind the router. Then the rays will be reflected back to you and not wasted.
I’m about 62% sure this is a joke…
Please help, I’m clueless about this kind of stuff.
Look up the DIY parabolic reflectors people used to use on their WiFi antennas, they did actually work! I used one and recorded a marked improvement in WiFi strength at the furthest point in my home that was previously a low connection quality spot.
Radio waves come out of an antenna and just go in every direction, so a router against your outer wall is wasting a lot of its energy just directed into the neighbour’s house. If you can reflect some of that back in, you get improved signal reception. It’s very cool :-)
I think mirror won’t work, but this might:
It’s the same principle of al satellite dish and it works, but I’m 86% sure that mirrors won’t affect wifi, so we’re still not at 100% but getting there.
Depends on what frequency your “mirror” mirrors.
A traditional one reflects higher frequency of electromagnetic rays (visible light) than what you need for wifi (in the microwave frequencies)
So you’re saying the walls of an old microwave might do the trick
Jokes aside, anything made of metal will be a good enough reflector for most consumer use.
A coke can cut vertically in half makes a great parabolic relfector. Pepsi can maybe. Dr pepper not recommended.
Actually yes.
Microwave ovens work by exciting water molecules using many hundreds of watts of ~2.45 GHz microwaves.
This specific frequency has a heating effect on water, so when you blast enough of it at food, which is often very saturated with water, it will heat up. The heat energy will transfer to the rest of the molecules in the food by contact.
That’s the general idea at least… I’m sure there’s more interactions that happen, water is just the most significant, to my knowledge.
So the protection in the microwave is capable of reflecting (for the purposes of containment) 2.4Ghz microwaves very well, and bluntly, does a good job with many other radio waves too, across a pretty broad band of frequencies… so the material that makes up the protective chassis of a microwave is ideal for making a reflector for wifi, since it was constructed with the idea of reflecting 2.4Ghz frequencies. Microwave ovens create the signal fairly crudely with a magnetron, but the underlying concepts are the same.
So, wifi is made up of radio waves, specifically micro waves, which are all sub-classifications of electromagnetic waves.
There’s another common electromagnetic wave you’ve certainly heard of: visible light.
While the wording is a bit awkward, the previous poster isn’t wrong. Just, in radio, it’s referred to as a reflector, not a mirror. Same principle, different area of technology.
EM is incredibly interesting especially since all data communication, with the exception of copper wires, is EM. Fiber optic is light, which we’ve established, is EM, and wifi is radio, which is also EM. Apart from the copper in your ethernet/DSL/Coax cable, it’s all EM. It’s fascinating to me that we use EM for so much, and fiber is considered the pinnacle of data connections, yet, light propagates slower through glass than radio propagates through the atmosphere, so technically, wifi can get a signal from A to B faster than fiber can… and we put that stuff in our house.
All EM is at, or near, the speed of light. Glass, used in fiber, tends to slow the light down about 30% or so… that’s fascinating because the internet is largely fiber, and so the information for this or anything else on the internet is being delivered to your device at, or very near the speed of light.
Anyway, I’m off topic. I’m just a gigantic nerd about this stuff.
Technically yes, but in practice any gains are going to be counteracted if not outweighed by the electromagnetic noise from the fan’s motor. To avoid that interference and see any real improvement in your signal strength, you’d have to either use a fan with a shielded motor (the last such model went out of production in 1953, so good luck finding one) or a fan driven by an alternative power source such as a water wheel.
Pretty sure both parts of your answer is wrong
Yeah that’s true, but nah.
