Wow, what a load of crap! I wish I could get the 2 minutes of my life back that I spent speed-reading that garbage. Hey, I can also sell you a nifty device you place behind the battery of your cell phone to extend the range! This has to be however one of the funniest scam ads I have seen in some time. How do I know it is a scam? Notice, they did not even mention anything about the "flavor" of Wi-Fi being used! Notice: Technical content ahead. Commonly called the IEEE 802.11 standard, it is actually a wide range of protocols, signals, and standards. 802.11, 802.11a, 802.11b, 802.11g, 802.11n, and so many more. ac, ad, af, ah, ai, al, aj, aq, ax, ay, and others still under development. Most of these are not compatible with each other, and this makes no mention of which standard is needed, it is not just "Wi-Fi". Secondly, the nonsense of "weak routers" being the cause of slow speed. This thing sits outside of the router, on the "user side" of the equation. It providing a "faster" signal makes about as much sense as attacking a second fitting to the end of a garden hose making more water come out. Uhhh, yea. Nope, not gonna happen. But hey, I am sure that at $50 each some suckers are gonna buy it. Might as well plug in a Glade Plug-in air freshener. It will speed your internet up as much as this worthless hunk of coprolite (that is none at all), and it will make the room smell nicer also.
I have a question for you, Mushy. I get wi fi off my my neighbor who has one of those water cooled super duper computers. It's very fast. I used to get it off of my other neighbor whose was slow as cold molasses. Does their computers and their isp factor in? Thank you, Mushy.
Computer, absolutely not. Once again, it is on the outside, and has nothing to do with the speed of the Internet itself. Might as well claim that changing the tires on your truck will make your car perform better. If you got slower speeds off your neighbor, there are 10,000 other things that can apply. Distance between you and the source (router) and what kind of construction was between you and them, number of devices attached and pulling off of the signal, the type of service they were paying for, and once again many other things. Their computer does not matter at all, you are not connecting to their computer but to their router. ISP, only in what kind of bandwidth are they getting. 500 Kbps is the same, be it through DSL, Cable, Fiber, or OTA. Although of those OTA (over the air - in other words cellular) is going to have a higher latency which will affect performance. That is the issue seen in the various satellite systems. The bandwidth is high, but so is the latency.
internet speed is dependent upon your isp and your service level, nothing else will make it faster... hardwired to your router is faster, safer, more reliable than using it wirelessly... that said: this is interesting: https://www.mushroomnetworks.com/
