Review on Enhance Your Wi-Fi Range with TP-Link N300 Range Extender (TL-WA850RE) by Stanislaw Mlekodaj ᠌

I took it from a friend to use it (he bought it, but did not use it). I have a Mikrotik router, and I wanted to expand the blind zones. I plugged it into a power outlet, connected to the Wi-Fi of this repeater, set it up, put it in the kitchen, so that there would be enough coverage in the yard (private house). At first, it seemed to be nothing, moving around the house, the signal reception was everywhere, but judging by the level, there are failures. One gets the impression that the mobile device either connects to another point (when closer to it), then to another, and at these moments the Internet seems to be there, but at the same time it is not. The connection speed jumps a lot, then more than 100MB, then 2-5 MB while being a couple of meters from the repeater. And the next day, at all, the Internet was only in the confident zone of the repeater, but there was no Internet from my router through the air. Even if you turn off the repeater, the Internet is only available via cable. What he did with my router, I'll figure it out. It’s good that I didn’t buy it, I will look for something else, and most likely, I need to look for something much more expensive. Judging by the reviews, cheap devices in general behave the same way as this device.
