I started using this product since August 2024, for the convenience of building a small-scale shophouse business network easily without cables. After browsing several online sites, my choice fell on the Tp-Link Deco X20 product (which I got version 3.20).

The first day I used this device was very bad, yes the signal was strong, it could reach between floors, but the connection was bad, even only 3 connected devices could not connect to the internet.

I thought there might be a setup error, because it was my first time using this device, but after I saw various tutorials available online, there was nothing wrong, I had done the standard settings correctly.

Until finally after a week later I decided to go back to using the old way, yes .. by using a cable network. And for my laptop/smartphone connection I use Tl-Wr840n, not as strong as the deco signal, but the connection is much better.

Until now I have continued to try to maximize the capabilities of this Deco X20, I admit the signal is strong, but why is there always a bad connection problem?

You may think this only happens to 1 device, no.. not only 1 device, I bought 2 sets of 6 devices, I tried them all one by one and had the same problem STRONG SIGNAL BUT POOR CONNECTION.

Is there anyone else experiencing the same thing? And do you have a solution?
