    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.

          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. 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.

      I’m no expert but from my experience it is the other way around: Upload speed increased, Download speed decreased. Which makes sense because the outgoing data is boosted by the wind whereas the incoming traffic has to overcome the wind. If you want to increase download speed I suggest placing a hoover behind the router.

      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.

      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

    Well… WiFi is bidirectional. It may be faster receiving but the device sending… Other story than the tcp handshakes…

    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?

        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.

    May work in niche cases where passive cooling is insufficient and overeating causes Instabilität.

    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

      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.

    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…

      Even if they were affected by any measurable amount, the photons move so much faster than the air that it’s an absolutely negligible difference incapable of being measured. It’s like 1 trillion divided by 1 trillion and 1 equaling approximately 1. The outcome is unaffected by the extra 1. It’s a non-factor. I’m trying to explain this for the future not-smart-people but I think I’m just making it much worse.

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