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.
That's absurd. You don't need to route to or from your router. That's it's entire job. Do you also run computations for your computer and speak on behalf of your speaker? Complete madness.
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?
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
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. 👍
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)
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…
Just use an electromagnet instead. Invert the polarization to attract or repell all those pesky wifi particles. This way it boost botb up and download speeds.
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.
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.
Putting a fan begin your router won't boost the range because photons emitted by the router's antenna won't be affected by moving air from the fan. Putting a floodlight however...
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.
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.
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.
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.
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 :-)
But if waves transmit information, and the same information comes at all sides, won't the signals that bounce off the reflector arrive after the waves with a direct line and thus transmit redundant information?
When creating a reflector, you want to place it a specific distance from the focal point, so the waves are in sync with the waves going direct to the device, they will be offset one or two full wavelengths, but that hardly matters. About a half wavelength away from the emitter/antenna is ideal.
There's also a way to calculate the parabolic arc you want to make the signal very directional (the way a satellite dish works, but in reverse. Those dishes collect and concentrate the signal, in this case you want to redirect the emission in the same direction - think about it like a flashlight, where the majority of the light is in a small cone in the middle, but there's still some light going everywhere that isn't blocked by the mirror reflector dish in the flashlight).
There's a hundred different ways to get this done, tons of antenna designs to work with, but in general, wifi uses beamforming, which is a method to use multiple antennas that are transmitting the same signal, but they have the exact waveform slightly offset from eachother, which makes the signal much stronger in the complementary direction. It basically generates a beam the hard way. Wifi has gotten very good at doing this, so reflectors and directors, and all that fancy antenna design stuff isn't really required.
The only real improvement to be made, given wifi's current complexities, is to put in larger antennas; most wifi antennas are quarter wavelength or often smaller.... "Upgrading" to well matched full wavelength antennas may yield some benefit, but there's a lot of nuance there too. It's a deep subject so I'm just touching on how things go. I find it fascinating, I'm sure not everyone does.
Waves can bounce off of everything, wifi/Bluetooth/cellular automatically compensate for this effect. There is a lot of signal processing involved with wireless data transmission to filter noise and correct errors. This is part of the reason why it's taken decades to reach this level of wifi speeds and why Bluetooth has a real hard time matching wired audio.
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.
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.
If it's a silver layer on a glass/plastic pane (like basically any mirror) and it's big enough (more than idk, let's say 20 cm to be safe) why wouldn't it mirror the lower frequencies too?
I'm not fully versed on all the physics of it, but to my understanding, the layer of silver that makes up the reflective surface of a mirror is crazy thin, like, less than the thickness of paint.
The basic concept I was explained is that the longer the wavelength (lower frequency) the easier it is for it to penetrate obstacles, specifically things that are relatively opaque to radio waves. The very high frequency (small wavelength) waves of light, are so small that almost everything interacts with them; so when they make it to the silver layer, despite that silver layer being impossibly thin, the >100THz waves, will bounce. When dealing with stuff that's much lower frequency (like 2GHz to 5Ghz, many orders of magnitude lower frequency), there's not enough of the material to interact with the wave to have any significant effect on its propagation, so it passes right through.
This is a good observation and a great question. I'm sorry I couldn't be more specific, I'm just not as well versed in the physics of it all to really get into the details; but I hope this helps.
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.
In all seriousness, you can have two completely independent routers operating on different channels that don't interfere. This is how large wireless systems work. A large number of wireless access points (same basic premise as a wireless router, but with more wireless features and fewer router features), each will operate on their own frequency that won't interfere with it's neighboring access points. There's a limit to how far this goes, since there's only so many non-overlapping wireless frequencies....
The idea is to move the access points into places that are far enough apart that when you run out of non-overlapping frequencies, you can re-use a frequency that's been used, but is in use far enough away that it won't interfere.
The idea that adding more radios will boost your signal.... that's valid, but the radios need to be very carefully managed to ensure that everything is working in a way where that goal is achieved. This is the foundation of how beamforming works. Each wireless interface is a set of radios; you'll see this advertised as something along the lines of 3x3 or 2x2, on spec sheets. More is better, but both sender and reciever needs the same number to get the full effect. Most cell phones and laptops are 1x1 or 2x2.... how this makes beamforming happen is that one will transmit slightly before the other, and because of the difference in their placement the two signals create what's called "constructive interference" and they effectively combine into a stronger signal.
The big trick to get all this working with wifi, is that all the radios are effectively on the same chip. They're about as closely bonded as they can be. Trying to do this with two different radios in two different devices is nigh impossible. It's certainly impractical.
I'm pretty sure thats unpossible, try a microwave and some garlic it should boost the signal, direct the antennas from the router to the most metallic part of the microwave and the microtextural bogoconductor + full-duplex planck magnetoms as well as the quantized garlic aroma should distribute the signal more evenly around the room (even through walls) than the antennas ever could. Trust me I'm an enginer I've trained for this moment my whole life
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
Then you add ping by changing the path
You can counter those with a pingpong bat.
If you play pong online, your ping will be super low.
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".

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!

Yes I do, computers calculate okay but I'm different
I bet you fing too, you monster.
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
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.
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.

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
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. 👍

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.
We use it for talking to distant satellites, but then we also combine arrays of large directional dish antennas with beam shaping algorithms

The reflective part of mirrors is silver, but yes
But how does the mirror knows what's behind the paper?!
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. 👍
Just use an electromagnet instead. Invert the polarization to attract or repell all those pesky wifi particles. This way it boost botb up and download speeds.
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

Same here. 🤣 I absolutely love when people have the skill of typing out something that your brain reads in a specific voice and manor.
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.
Radio waves are faster in a vacuum, ditch the fan and put it in a shop vac.
But the fan blows the air away, leaving nothing but vacuum
Putting a fan begin your router won't boost the range because photons emitted by the router's antenna won't be affected by moving air from the fan. Putting a floodlight however...
Photons?
Visible light, radio frequencies, microwaves, x-rays, infrared, ultra violet and so on are just light (photons) at different frequencies.
And your friendly EMH.

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!
No no no we make use of MIMO beamforming and let the uplink signal get reflected towards the back of the fan so it slipstreams into the router
Technically yes, but in practice any gains are going to be counteracted if not outweighed by the electromagnetic noise from the fan's motor.

Pretty sure both parts of your answer is wrong
Yeah that's true, but nah.
Well... WiFi is bidirectional. It may be faster receiving but the device sending... Other story than the tcp handshakes...

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.

Anyway, I'm off topic. I'm just a gigantic nerd about this stuff.
It works better if you tie the router to the fan blades.
It will help cool the router, so yes, it will probably work 👍
I mean... closing the window keeps the wifi in so I think this will disperse the wifi instead.
If you put a lamp on the front of a train going 100 m/s, does the light coming out of the lamp go C+100?
If yes then the fan will totally blow the wifis all over the place and give better signal
It's literally the thought experiment Einstein lays out in his book on Special and General Relativity.
Now, let's say you are on a train moving at 0.1 C and you observe a lightning bolt striking the front and the back of the train at the same time...
use a fan with metal blades
And put weapons grade Uranium in front of it to get the quantum boosts.
A bunch of Jerry's in the comments.

Why is it NSFW
The fan lacks a safety cage so it's not safe.
Not grounded

It would actually make more sense to put in in front of the router 😅
Yeah, but I'd be worried about my files getting sliced up by the fan blades.
You could change the MTU size to allow for smaller IP packets without causing fragmentation.
Or switch to TCP, or use error correction with UDP.
Forward error correction algorithms to handle packet losses
Yup i tried it and it worked...
Probably a boost from a better cooling condition.
Hmmm. 144 000 000 000 RPM for 2.4GHz, a bit fast you may need a better fan !
Not safe for work
Wifi are em waves switch on oven for higher speeds
Why do I get better phone signal when the wind is blowing the right way hmmmm
Yeah, duh!
Yeah but you’re gonna have to download more RAM first
No - but you can connect to two routers at the same time, because then the waves will amplify each other making the signal stronger.
I'm a big metal fan. Will my presence boost my Wi-Fi signal?
How would this work? Doesn't each router broadcast its own signal? Wouldn't they interfere?
The poster is being sarcastic.
In all seriousness, you can have two completely independent routers operating on different channels that don't interfere. This is how large wireless systems work. A large number of wireless access points (same basic premise as a wireless router, but with more wireless features and fewer router features), each will operate on their own frequency that won't interfere with it's neighboring access points. There's a limit to how far this goes, since there's only so many non-overlapping wireless frequencies....
The idea is to move the access points into places that are far enough apart that when you run out of non-overlapping frequencies, you can re-use a frequency that's been used, but is in use far enough away that it won't interfere.
The idea that adding more radios will boost your signal.... that's valid, but the radios need to be very carefully managed to ensure that everything is working in a way where that goal is achieved. This is the foundation of how beamforming works. Each wireless interface is a set of radios; you'll see this advertised as something along the lines of 3x3 or 2x2, on spec sheets. More is better, but both sender and reciever needs the same number to get the full effect. Most cell phones and laptops are 1x1 or 2x2.... how this makes beamforming happen is that one will transmit slightly before the other, and because of the difference in their placement the two signals create what's called "constructive interference" and they effectively combine into a stronger signal.
The big trick to get all this working with wifi, is that all the radios are effectively on the same chip. They're about as closely bonded as they can be. Trying to do this with two different radios in two different devices is nigh impossible. It's certainly impractical.

Just buy a satellite dish off eBay and place it behind the router
I'm pretty sure thats unpossible, try a microwave and some garlic it should boost the signal, direct the antennas from the router to the most metallic part of the microwave and the microtextural bogoconductor + full-duplex planck magnetoms as well as the quantized garlic aroma should distribute the signal more evenly around the room (even through walls) than the antennas ever could. Trust me I'm an enginer I've trained for this moment my whole life
here's an illustration hope it helps and have fun with your better internet now!
You just need to sprinkle metallic dust in the airflow and you're ready to surf the web at dangerous speeds!

Run a longer wire.
Speedy speed
Yes.
