The Picard ManeuverImprove your Wi-Fi with this one trick
carl_dungeonThere are some stupid questions.
I mean technically the weather influences your ping, since the waves travel faster at higher air pressure
henfredemarsI’m not sure if you’re being sarcastic but this is not true. Electromagnetic waves travel fastest in a vacuum, so the presence of air would slow it down very slightly and I would expect higher air pressure would slow it down further again only incredibly slightly because the electromagnetic waves would be traveling through a medium less efficient and more different than a vacuum.
Of course I’m making an assumption that you were using wireless signals. For all I know, you could have some weird acoustic link in which case you’d be absolutely right.
Internet via carrier pigeon. A strong headwind will reduce your effective transmission time.
I believe this mode of communication was actually standardized.
They would travel slower at high pressure and high temperature due to more interactions. Low temp and low pressure are the opposite. Sound is also the opposite on pressure and more complicated on temperature.
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 yeah, I know. I was mostly just kidding. Everything is magic if you’re ignorant and we shouldn’t shit on people for not knowing something and props to them for asking and seeking knowledge and all that.
But it’s really sad that very basic science like radio waves which are introduced in 5th or 6th grade could be some completely misunderstood.
I remember my 6th grade science class having a lively 15 minute discussion about whether or not rockets can work in space since there’s no air…. We’re looking at videos of rockets working in space and then debating whether or not they do. 🙄

This feels a tad different than the person in the screenshot. Screenshot person fundamentally misunderstood how rasio waves worked. Meanwhile, 6th grade you absolutely understood how rockets worked, at least to the level of understanding that they need air to work. Because you were right the whole time, those kinds of rockets can’t work in space without air. The slightly absurd solution that you wouldn’t readily know without a deeper understanding of how the rocket is built is that a rocket literally brings its own air with it.
Yeah- you make good points. I think what I was upset about was that we started with a given (they obviously work in space) and then half the class argued they didn’t for a while.
A better question would have been “how can they work since space has no air in space?” which leads to great q & a I think.
Not everyone went to the same school, and not everyone went to school, for any number of reasons. I first attended a health class in college.
Even less intuitively, the fan would increase the air pressure between the router and receiver, slowing light down slightly. So it would end up (imperceptibly) slowing the signal down.
Quantum physics is not logical, every other field of physics is! Shame that instead of logic we are taught fucking equations, as if we could look up logical conclusions like equations…
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”
“I don’t know, can anyone help me learn?” gets so much respect from me. Incredibly powerful mindset.
it obv goes through the ether
Oh, wow. You really triggered them this time.
This is not stupid at all. If Wi-Fi used matter instead of magnetic fields to propagate (like sound waves), a fan would affect it. Understanding magnetic fields is anything but intuitive.
Agreed, it’s just someone trying to learn.
Alternatively I would guess if fans improved the speed we’d have wifi fans throughout the house. Gaming wifi fans that sound like an airplane taking off with blinding LEDs
Imagine…
Not at all in this case though! Or rather, it depends on your perspective.
“Why doesn’t electricity leak out the outlet?” is a good question, if you know nothing about electricity.
“Why doesn’t electricity leak out the outlet?” is a little stupid, if you know a little about electricity.
“Why doesn’t electricity leak out the outlet?” is a great question if you know a bit more about electricity (because it does leak out, it’s just that 50/60Hz doesn’t couple to freespace well unless you have a colossal antenna).
As to this question, light in a moving media: preprints.opticaopen.org/articles/…/25441108?file…
Fizeau Experiment: Investigating the Speed of Light in Moving Media
This research extensively investigates the speed characteristics of light in a medium through the Fizeau experiment. By leveraging the particle properties of light, a physical model of particle movement in a medium is constructed to dissect the underlying physics mechanisms. The experimental data and theoretical analysis mutually corroborate, revealing the influence of the relative velocities between photons and the electric field, as well as between photons and the medium, on the speed of light in a medium. This research provides a rational justification for the Fizeau experiment and holds significant importance for the research and utilization of light.
Esp those pushed to devices with the form factor of a remote control, running the official reddit app
^yes^ but ~pages~ will ^render^ kinda ~wavy~ i ^use^ a ~box~ fan ^myself^ for ~maximum~ speed
Eager Eagleand you can speedup your upload by switching the fan direction
Fan facing up for upload and down for download, very intuitive.
don’t forget to compensate gravity
Gotta get me one of those oscillating routers.
They do kind of oscillate, just very very quickly.
Depends on the direction the fan is facing. If it’s blowing towards you, that increases air pressure in front of it, which means more things for photons to interact with and a lower speed of light, thus slower wifi. Away from you would decrease the pressure and result in faster wifi due to the increased speed of light. Theoretically at least. I don’t think this effect is measurable.
Not gonna lie, I thought about that, but I didn’t wanna risk sounding stupid, so I just google it instead of posting it on a forum. Luckily I didn’t actually make a forum post.
It is amazing with how little to none in education is sufficient to finish school nowadays.
I learned more from the internet than everything that public school taught me. That’s not to say we should stop funding school, but in fact, we should fund it better, and have more qualified teachers.
If I make an analogy between a wikipedia article, knowledge I learned. I would say that public school taught the eqivalent of the summary paragraph at the top of a wikipedia page, while the internet taught me the rest of the page. That’s how much school just don’t teach.
Example, School didn’t teach: (This is the USA btw)
- Ranked Choice voting (or any alternative voting method, for that matter)
- National Popular Vote Interstate Compact
- Citizen’s United ruling
- Although they did teach 5th & 6th amendments and Miranda Warning, they didn’t be specific and teach the fact that you have to specifically invoke your right to silence. Just remaining silent itself can be used as evidence of guilt.
Amonst many things
School definitely doesn’t teach how wifi works, or even how technology works in general. School never taugh about the fact that you shouldn’t ignore HTTPS warnings. I’m pretty sure like 99% of my school would just instictively click pass an HTTPS warning and just get their info stolen, although we do have HSTS now so we should be better now, but still, there are many other phishing that almost all of my school-mates would fall for, and they wouldn’t even think to scan the sender address or do any verification that its legit.
My (European) school education at least taught me that speed of light (and therefore other electromagnetic radiation, too) can be assumed to be the speed of light without any measurable difference applied by the medium it is passing through.
How do you know that redditor finished school? There are kids on the Internet.
I like this question tbh
jia_tanI hope this is the final straw for OP to finally delete the app that shall not be named
ZachariahWiFi is waves in space, not air.
Followup: Can I get a fan that moves space instead of air? I need to make my wifi faster.
You can define your fan to be moving space and the pushing of air is the side-effect.
Followup: So I need to get a fan with this symbol on it: ☢️?
There’s a few on eBay, but the sellers are all Russian and I’m not sure if they’re scams or not.
I guess I’ll look for radiation fan on Amazon.
Build your own fan out of bananas and you have a radiation fan.
Just get a tube of argon that you can connect from your wifi ap to your device so the waves can travel faster through the tube
So SCUBA for inside the house breathing while gaming, zoom meeting, etc. That's totally doable.
SCBA would be enough.
Just have a miniature wormhole connect your PC directly to the server
Check on Amazon for a “Space fan”.
Waves in the electromagnetic field that permeates all of space, along with many other fields with different topologies and particles.
Technically?
No.
DJDarrenThis might sound stupid, but that’s because it is.
Yeah, but it evens out since now your messages going back to the router have to swim upstream.
Something Burger 🍔Could this be remedied by sending packets on a second antenna, with a fan blowing in the opposite direction?
GhostlyPixelOnly if the two air streams don’t intersect, otherwise you’ll create a dead zone. Modern signal jammers are actually highly sophisticated fans.
You must never cross the streams
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
VindictiveJudgeBitrate wouldn’t change, but it would reduce latency by a tiny amount.
With less matter for the photons to interact with, I assume the WiFi’s SNR would be improved. If fewer data frames need to be retransmitted at the link layer (WiFi), I figure the apparent bitrate at the IP level might actually be improved!
Actually, I would not be shocked if WiFi itself adapts to conditions, e.g. by sending less data per frame with more error correction bits when SNR is already low.
(Not a networking expert, I am just bullshitting.)
Yes, but then it’s slower for your computer to talk back to your Wi-Fi, so it ends up cancelling out
LOL! Yes, one has to consider this. ZOMG your's is the best comment!
Le reddit moment tips cap to you sir
