I bought this product half a year ago. After I bought it, I put these three decos in place and the situation was not so bad. But now the network is unstable from time to time, causing my game to lag. And I don’t feel much difference between using deco and not using deco. The network speed tested by the computer is completely different from the one I tested with deco. After I couldn’t connect to the network for no reason last time, another identical network appeared on my computer, but I didn’t set it up. I don’t know if my problem can be solved
