Yes, but only in one direction and if you use UDP instead of TCP. Also your MTU needs to be small enough for the packages to fit between the blades of the fan, otherwise that causes package fragmentation.
/s
Yes, but the tailwind becomes a headwind on the way back to the router so you won't see any actual speed changes. Putting a fan on both ends will cancel each other out too.
You need to change all the gaseous air out for either liquid or a solid as waves propagate faster through them. You should start with filling your house with liquid oxygen as a nice half step so you still have something to breathe easily, as solids are a bit more tricky.
The general idea is correct, but since we're dealing with electronagnetic waves, they travel slower in any medium. So pumping out all the air of the room would technically make your wifi faster.
Liquid oxygen has (I think) a refractive index of about 1.2, so it would make the signals 20% slower (still very fast)
NERD
Dude waited 11 months of lurking and not posting or commenting anything, and breaks their silence with that attractive string of knowledge. I've got mad respect for them.
I'm a nerd too but come on, he's replying to an obvious joke with high school physics. There are more layers, do you want a more pedantic teardown?
- Most likely, the "Wi-Fi speed" the Reddit poster needs to improve is the data rate, not latency.
- The data rate can be improved significantly by increasing RSSI with a better physical setup, WDS, higher power etc. However, if the rate is too low at full bars, the bottleneck is the ISP plan or hardware specs.
- The latency cannot really be improved without changing hardware or software, as the highest impact one can influence is in processing by the router and device. Some settings such as DNS cache size can improve latency in some cases with some downsides.
Meh, we all have our personalities. A lot of people hate my personality, but I just figure it's best to assume everyone on the internet is a stranger that could be a potential friend. If they answer things blunt or love to extrapolate with excruciating detail... Who am I to judge. I just make jokes and hope they don't accidentally make someone feel bad. Like I really wanted to reply to yours saying that you were just trying to show off and get me to call your words attractive as well ; ) haha.
What if i put the router in front of an open window, open the window behind my computer and put a fan between the two ?
No, the fan will blow the packets all over the place, which is fine for UDP, but any TCP/IP connection will suffer. Place the fan in front of the router so that the blades will catch any dropped packets and throw them back into the datastream.
uh, hi. If you place the blades in front of the router, it will start chopping the packets before they even reach. You need to use an bladeless fan
Alright so I've now got a router using cell signal hardwired into a Roomba randomly roaming the halls so everyone gets shitty connections all the time.
No need, that's why we have the Don't Fragment bit in the IP header
Everyone know that.
It's not 1 way traffic. Signals go both ways. To increase your wifi speeds, have 1 fan blow from your router to your device and 1 fan from your device blow towards your router. Signals go faster in warm air so make sure to pump up the thermostat. It also goes faster with less CO2 in the air so make sure to open all windows (unless you own a Mac). Lower moisture in the air also improves speeds, so crank your AC on max. Also placing both your router and device in rice helps.
device in rice
Say that in any linux forum :)
If you can create a vacuum with said fan, it can be faster.
Maybe if you made this vacuum encapsulated in a line. Surrounded by shielded metal and plastic.
The Wifi isn't waves made of air, the wifi is waves of the electromagnetic spectrum, similar to visible light, and they travel faster than you can perceive.
So no.
But you can do something similar with a microwave oven. It's just that any signal making it through the radiation of the oven would be disfigured and useless.
I mean, that was my first thought... but would there be a measurable difference?
I mean lets be clear, with a fan you're adding like 8 mph to something going 299,792,458 meters per second. You won't notice anything.
But like, vacuum vs glass vs glass moving half the speed of light, could be an interesting what if. Relativity is always where my mind glosses over in physics.

yes.
Yes, but then it's slower for your computer to talk back to your Wi-Fi, so it ends up cancelling out
Push-Pull Config
We can streamline this by making the room into 2 small tunnels from the router to the PC. This way there will be less obstacles in the room. But we need to add leafblowers on each side with a boost button.
What if we make the tubes really really small and wrap them in many protective layers to prevent other wind sources from messing with the signal.

you could also hook into the router and wireless card of the computer to make each of them turn on the corresponding leaf blower whenever they’re sending something. of course you’d probably have to implement some kind of queuing system so only one blower is active at a time, but it will all be worth it for the speed gains
Interestingly, this could be true and you could never find out experimentally iirc.
I watched a veritasium video about the 1 way speed of light vs 2 way that talked about it.
I watched the same video!
I was right about to disagree and type “wait this only applies to light” but then I remembered: radio is light.
Crazy to think about that!
It is nuts. It goes to show how far science goes proving things through deductions rather than direct observation. So much science is done that way.
I think that there would be some infinite energy glitches if it was actually true that light was faster 1 direction than another, so I think the assumption is a good one. But still fun facts

Sort of a serious answer because I'm bored: You're thinking of speeding up the air when what you should be thinking about is speeding up the waves. But then your waves are reaching you plenty fast already with latency being in the single digit ms range. Not much of a point in trying to accelerate that, really. You won't notice anyway.
If you feel like your internet connection via Wi-Fi is slow then the bottleneck is probably not with the Wi-Fi part of your network but the Internet Access Point behind it. Or even further down the line.
Now this is based on the assumption that you are in a fairly typical network environment, i.e. using semi-current hardware with moderate, if any, electromagnetic interference in the area. If you're living right next to a high voltage transformer station and using a router from 2008 then, yes, you're going to have Wi-Fi performance issues.
But in most cases, people complaining about "slow Wi-Fi" are actually suffering from Internet connectivity issues.
Think of it this way: If you enjoy your McDonald's from the local franchise but you can only get 100 burgers per hour from them (of course you need MOAR!) then upgrading your 320hp Camaro to a 400hp Mustang is not going to enable you to pick up appreciably more burgers from the drive through in the same amount of time.
Not entirely true.
In an apartment in the middle of a city, noisy neighbours can be a problem.
In those cases, it's best to jump to 5 GHz, and leave the 2.4 band alone.

There are plenty of things in a normal home that can cause serious signal attenuation (just installed new energy efficient windows? whoops! those IR blocking coatings severely attenuate microwave signals too). Poor AP placement is a very common cause of "slow wifi" and has nothing to do with your internet uplink.

^yes^ but ~pages~ will ^render^ kinda ~wavy~ i ^use^ a ~box~ fan ^myself^ for ~maximum~ speed
Remember: These people vote.
Reminder: most voters are the people.
Yes but you have to put a slit in front of it so the wifi waves turn into wifi particles.
Not inherently stupid question; they just don't know that radio waves don't travel through air but through space.
What is space exactly?

Yeah, but it evens out since now your messages going back to the router have to swim upstream.

There are some stupid questions.
Tbf, it’s not like physics stuff is always obvious, especially when dealing with relativity or quantum mechanics. It just feels obvious if you’ve already learned about the research that’s already been done.
It isn’t even remotely intuitive that light should have a max speed that can’t be added to by moving its source relative to other things. Plus, light does interact with matter, but it can only be slowed down by it.
So less a stupid question and more just one that isn’t educated about something.
Yeah, what if I'm moving my router at the speed of light, not so intuitive now

On the contrary, given the premise its a smart observation from an unknownledged person.
“Wifi is waves in the air” is very very wrong but as it appears it’s what this person was thought to believe. Given that they trust this information the conclusion makes perfect sense.
The only “dumb” here is whoever explain wifi like this to them.
So what the post really amounts to is. “I applied actual reasoning to the information i was provided as fact and my conclusion seemed strange, so i will ask on no stupid questions to figure out whats really going on”
More intelligent than the majority of internet users.

So if I put a fan behind a source of light, shouldn't that make the particles faster?
Yeah but it's gonna scramble your signal, then send it spinning outwards.
If you had a fan blowing out the window, it could slightly reduce the density of the air in your house, leading to a tiny increase in the speed of light through it, so that would make the waves technically faster, but by a vanishingly small margin
It wouldn't increase the bitrate of your router at all, so it wouldn't make a difference, but the waves would be faster
