While looking at the weather report for my area on weather.com, I saw an ad for this SignalTech wifi booster with some text saying internet providers don't want you buying one. I was curious if it was some kind of special device or not, so I decided to click on the link. This is from SignalTech's web site:
https://signaltechbooster.com/info-21.php
Basically what it says is that internet providers throttle your router to make your internet speed become slower over time so you'll upgrade your internet package. This already sounded suspicious to me, because I haven't had this happen to me (though I tend to buy my own router and use 3rd-party router firmware, such as DD-WRT or Tomato). I suppose it could theoretically happen with an ISP-provided router, but even then it seems sketchy and I haven't heard of this happening to other people.
Next, it says that this SignalTech wifi booster "overrides what the internet provider does with your router and boosts your internet to every corner of your house". This sounds highly suspicious to me. If the internet provider is throttling your router speeds, I don't really see how a wifi device like this would be able to override what the ISP is doing to your router. Also, this is a wifi repeater; what about ethernet speed?
And to top it off, that page has a section that says "How does this device work?" and it explains what bandwidth is, but it doesn't actually explain how this device supposedly overrides any bandwidth throttling from your internet provider.
It all sounds bogus..
