Genius. Where’s your GoFundMe?

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!

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. 👍

The reflective part of mirrors is silver, but yes

Get back to making me work!

this is far too complicated, we just need another fan blowing back toward the router

I work in IT and we always say stupid shit like this to people.

It's a vicious cycle. But you already knew that, doctor.

Same here. 🤣 I absolutely love when people have the skill of typing out something that your brain reads in a specific voice and manor.

Yeah that's true, but nah.

I think mirror won't work, but this might:

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.

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...

Not grounded

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.
